Brazed plate exchangers with ASME certification and CRN code for Canada

20/03/2026

Tempco is pleased to announce that it has obtained ASME certification with CRN code for the use of its brazed plate heat exchangers in the Canadian market.

CRN (Canadian Registration Number) number is a unique code issued by Canadian provincial/territorial authorities, required for the installation and use of pressure equipment, such as boilers, heat exchangers, pressure vessels, and fittings (fittings, valves, piping) in Canada. CRN certification is mandatory for equipment operating at pressures above 15 psig (approximately 1 bar) and, in the case of Tempco, ensures that the design and engineering of our brazed heat exchangers comply with Canadian safety standards.

A key safety requirement for importing and installing pressure-bearing components in Canada, this new certification, combined with the ASME certification, ensures that Tempco brazed plate heat exchangers comply with Canadian industry standards. Specifically, the CRN code is valid for installation of our brazed plate exchangers in the provinces of Ontario (ON), Quebec (QC), British Columbia (BC), Alberta (AB), and Saskatchewan (SK).

Brazed plate exchangers for hydrogen applications, electrolysis and fuel cells

13/03/2026

For hydrogen applications, such as electrolytic cells and fuel cells – systems involving less challenging operating conditions than hydrogen refueling systems with PCHE printed circuit exchangers – our partner Kaori has developed, through years of experience in the sector, a complete range of brazed plate exchangers, ideal for the production of green hydrogen through electrolysis and for fuel cells.

Fuel cells are electrochemical devices that convert the chemical energy of hydrogen into electrical energy with high efficiency, producing water and heat as a byproduct. Green hydrogen (green H2) is therefore hydrogen generated from renewable energy sources, with no carbon emissions. Water electrolysis is the most commonly used method for hydrogen generation, using a chemical reaction that separates hydrogen from oxygen.

As a green energy, green hydrogen can therefore be used in a variety of sectors, replacing fossil fuels and promoting the energy transition. Green hydrogen can be used for fuel cells, but it can also serve as a direct energy source for aviation, marine, automotive, and heavy-duty transportation, as well as for on-site industrial power generation.

Regardless of the type of electrolytic cell technology – be it PEMEC (proton exchange membrane electrolyzer), AEMEC (anion exchange membrane electrolyzer), AEL (alkaline electrolyzer), SOEC (solid oxide electrolyzer), or any other electrolysis technology – brazed exchangers offer high-value, high-efficiency solutions for electrolysis equipment, electrolytes, reaction water and gas preheating, working fluid cooling, and system energy recovery.

For these hydrogen applications, Kaori offers two types of brazed plate exchangers: the high-nickel alloy exchangers are the ideal solution for high-temperature SOEC/SOFC applications, capable of operating at temperatures up to 900°C. The new full-stainless steel brazed exchangers use stainless steel as the brazing filler material. This makes them suitable for hydrogen generation via PEM electrolysis and for fuel systems, or for low-conductivity deionized water that does not allow the passage of copper ions.

Electric fans, stricter energy efficiency requirements from 2026

06/03/2026

The new Regulation (EU) 2024/1834 is scheduled to come into force on July 24, 2026, defining new ecodesign requirements for fans with an electrical input power between 125 W and 500 kW. The new regulation replaces the old Regulation (EU) 327/2011 and aims to tighten the minimum energy efficiency levels these devices must meet.

These devices are widely used in temperature control, cooling, and thermoregulation systems in the process industry developed by Tempco. The regulation defines a fan as a device consisting of at least three components: stator, rotor, and motor. The fan must therefore achieve the minimum required energy efficiency at its optimum operating point, where efficiency is calculated as the ratio of airflow performance to electrical power input.

The new Regulation on electric fans also requires more information on partial loads and specifies the documentation requirements for the manufacturer/distributor/user, including information on reparability in addition to efficiency. The regulation thus aims to promote the development of the circular economy through the availability of spare parts.

Image showing an installation of electric cooling fans in the process industry, devices for which the minimum energy efficiency limits are expected to be tightened from July 2026.

The new requirements, which increase energy efficiency performance levels for fans compared to those established by the previous Ecodesign Regulation, will therefore further reduce energy consumption in industrial systems for temperature control and cooling. These savings can also be further increased in electric fans through the use of inverters and systems that adapt air volume to actual process needs, thanks to speed regulation.

Fans that comply with the minimum energy efficiency limits set by the regulation are recognized by their CE labeling, certifying their compliance. Only fans that comply with the CE regulation will therefore be allowed to enter the European market, regardless of whether they are manufactured in the EU or imported from non-EU countries.

Finally, a transition period until July 24, 2027 is foreseen to comply with the new efficiency requirements and the extended documentation requirements imposed by the regulation for fans installed in other products, so-called built-in fans.

Thermal control units in chocolate forming and cooling 

27/02/2026

Fine temperature regulation goes through every stage of chocolate production, to which we’ve dedicated specific posts in recent months, starting with the roasting of the cocoa beans, through refining, conching, and tempering.

Now we come to the final stage: forming and cooling, where the chocolate is poured into molds and finally takes its shape.

Image illustrating the final shaping and cooling stages with temperature control units in chocolate production.

After tempering, the chocolate mass is rapidly cooled to crystallize uniformly and achieve the ideal consistency. Low, stable temperatures, around 10-15°C, are essential to ensure the chocolate solidifies without defects, such as air bubbles or irregular surfaces. TCU thermal control units also ensure that the process runs smoothly during this phase, avoiding thermal shocks that could compromise product quality. Furthermore, well-managed cooling speeds up production times and optimizes the efficiency of the production line.

The magic of chocolate ends with this phase, leaving us with perfect bars, ready to be packaged and enjoyed. A precision work that transforms each piece into a masterpiece!

Brazed plate heat exchangers for high pressures up to 140 bar

20/02/2026

Brazed plate heat exchangers represent an extremely compact and efficient solution for heat transfer applications where space is limited and high performance are required. The standard version of these exchangers is designed for operating pressures up to 30 bar, but for more demanding applications, Tempco offers special high-pressure versions, with models capable of reaching 70, 100, and up to 140 bar design pressures.

One of the most common applications for high-pressure exchangers is gas cooling in compressors, as shown in the photo below: a high-pressure compression system for technical gases, where the exchangers are used to dissipate the heat generated during compression. In these systems, robustness and mechanical sealing are essential to ensure safety, continuity of service, and longevity.

Image showing a cooling system for technical gas compressors with special brazed heat exchangers for high pressure, up to 140 bar.

Therefore, these are some of the main advantages offered by this special type of high-pressure brazed exchangers:

• Compact design and simplified installation

• High mechanical resistance, up to 140 bar

• No routine maintenance thanks to the absence of gaskets• High heat exchange efficiency even at low flow rates

• Customized versions available for specific gases, oils, or process fluids

The high-pressure versions of brazed exchangers are also used in heat recovery systems, CO₂ hydraulic circuits, HVAC systems for transcritical refrigerants, and in the hydrogen sector, where operating conditions require absolutely reliable equipment.

High efficiency exchangers for liquid cooling in AI/HPC data centers

13/02/2026

The exponential global growth in computational capacity is driving the energy consumption of high-power chips. In AI and HPC (High Performance Computing) data centers, increasing power density is pushing air-cooled systems to their physical limits. On the other side, liquid cooling technology, which until recently was marginal, is rapidly becoming a core infrastructure, offering the significant advantage of ensuring thermal efficiency hundreds of times greater than traditional air cooling.

The AI/HPC data centers sector is therefore accelerating its transition toward the use of large-scale liquid cooling technologies, driven by the achievement of sustainability targets and high power efficiency (PUE) values ​​in new, large, high-performance data centers. To address this significant trend, Kaori, a Tempco partner in the field of heat transfer, recently introduced two new heat exchangers with highly attractive features specifically designed for new liquid cooling solutions in high-performance infrastructures.

This is the B390 heat exchanger, which features an asymmetric plate design specifically designed for high-density AI and HPC data centers. With a cooling capacity of up to 2.000 kW and support for 4-inch high-flow connections, it easily manages the transient heat loads of next-generation high-power servers. Measuring only 321 mm in width and 751 mm in length, the B390 offers exceptional cooling performance in a compact footprint—perfectly integrating into In-Row CDU systems while maximizing space efficiency.

Optimized for the pressure drop differences on both sides of In-Row CDU systems, the B390 ensures stable flow distribution and higher overall performance. It is available in single or multi-pass configurations and supports vertical, horizontal, or flat installations, providing flexible integration for various system and space requirements in data center environments.

B390 continues the core advantages of Kaori’s B Series:

  • Exclusive plate pattern design: maximizes heat transfer efficiency while maintaining low pressure drop.
  • High working pressure construction: ensures long-term reliability for high-pressure liquid cooling systems.
  • Compact design: pptimizes space utilization to meet high-density integration needs.

A second interesting heat exchanger model, also developed specifically for next-generation, high-density data center environments in the AI ​​era, is the K390. The same-sized K390 heat exchanger features a symmetrical plate design, ideal for balanced bidirectional flow systems.

Image showing a front view of an innovative, high-efficiency heat exchanger for liquid cooling applications in modern, high-density data centers in the AI ​​and HPC era.

Together, the B390 and K390 form a complementary solution, offering greater design flexibility and performance options for in-row liquid cooling architectures.

Thermal control unit for radiators test bench in Dallara Automobili

06/02/2026

Dallara is a historic Italian manufacturer of racing cars, true gems on four wheels that have shaped the history of Made in Italy motorsport over the years. The company was founded in 1972 in Varano de’ Melegari, in the province of Parma. In the high-performance world in which Dallara Automobili operates, extreme attention to detail makes the difference, and this also applies to cooling and thermal control.

With such a prestigious reference, Tempco is very proud to have contributed to ensuring the high performance of Dallara cars, thanks to the supply of a TREG HE temperature control unit employed for radiator test benches of Dallara Automobili’s racing cars. The unit is specifically designed to heat a thermal oil circuit, operating in a temperature range of +30°C to +180°C and transferring heat to the test fluid via a brazed plate heat exchanger. The flow rate range of the test fluid is between 5 and 80 l/min.

Test benches for these components are essential for laboratory simulation of the same track conditions that the cars will be subjected to during races. Tempco’s thermal control unit is therefore meticulously designed to ensure the simulation of the thermal conditions in which the Dallara supercar radiators will operate, precisely regulating the flow rates and temperatures of the test fluid with great stability and repeatability (temperature regulation accuracy ± 2°C).

Behind every tested radiator, there is thus a control unit that ensures that every degree truly counts in determining the maximum performance of Dallara racing cars. At the heart of the test bench, the TREG HE thermal control unit uses low-specific-power resistors, offering PID-controlled temperature regulation with proportional SCRs and integrated safety logic. An electro-pneumatic modulating valve ensures the necessary heat transfer stability even at low flow rates (5 l/min), maintaining the correct turbulent flow rate on the brazed exchanger.

Finally, the system was designed to always maintain maximum efficiency in regulating the temperature of the test fluid, taking into account the strong variability of the fluid’s viscosity as the temperature varies, together with the need to contain pressure drops.

Air/water heat exchanger for thermoforming in the medical sector

30/01/2026

We recently supplied an air/water heat exchanger with a special ElectroFin treatment for a medical equipment production line, specifically for medical tubing.

This specific application for the medical sector requires a precise and controlled cooling of the air temperature within the medical tubing thermoforming line. Rapid and stable cooling allows indeed the final geometry of the tube to be set immediately after forming, ensuring repeatability and consistent quality.

The solution used is an air/water exchanger made of UNI6082 aluminum with a special ElectroFin treatment. It is ideal for medical environments thanks to the corrosion resistance and sanitization of the surfaces guaranteed by the special treatment. This involves a series of steps that include testing and inspection of incoming parts, cleaning and degreasing of production residues, and e-coating in a cathodic epoxy bath. All with complete process traceability.

Integrated into the machine, the heat exchanger works with precisely regulated chilled water, maintaining the air temperature within the range required by the process. Thanks to the precise control of the air temperature in the thermoforming line, the result offered by the solution therefore involves greater stability, reduced waste and repeatable quality of the medical product.

New monitoring requirements for Legionella prevention

23/01/2026

The problem of Legionella has sadly returned to the forefront in the final weeks of 2025 in Italy, so we believe it’s important to take an opportunity to revisit the topic of Legionella prevention and control, which, in terms of thermal management, is closely related to systems using evaporative cooling towers. These cooling systems are equipped with a series of measures to prevent Legionella, such as self-draining tanks to prevent water stagnation, in addition to water treatment systems with additives that reduce algae and bacteria.

The Italian regulatory landscape on this topic has undergone a significant transformation in 2025: Legislative Decree 102/2025, which came into force on July 19, 2025, made mandatory certain Guidelines drawn up by the Ministry of Health in May 2015. The new obligations for prevention and control established in the Legionella Decree 2025 include:

  • Mandatory monitoring activities. Activities are now classified according to a Priority code. Water monitoring is now mandatory in facilities beyond the previous regulations, such as hotels, sports centers, and restaurants.
  • Preparation of the Water Safety Plan (PSA). The Water Safety Plan (PSA) is a mandatory risk assessment and management model for managers of internal building water systems.
  • Appointment of the Internal Water Distribution Manager (GIDI). For Priority facilities, the role of the Internal Water Distribution Manager (GIDI) has been introduced. The GIDI is responsible for the building’s internal drinking water system and must be appointed. He or she is responsible for verifying that analyses and the PSA are performed.

Finally, penalties have also been increased, with fines of up to 30.000 euro for failure in compliance with monitoring parameters.

Waste-to-energy and high-efficiency thermoregulation in circular economy

16/01/2026

Tempco is very pleased to share a new application case that combines industrial thermoregulation and the circular economy. Our TREG diathermic oil thermoregulation unit has been chosen for the pilot site of a major European project, installed at the end customer’s site in the Turin area.

The project aims to transform waste treatment into an advanced energy process: increasing biomethane production while simultaneously converting non-recyclable waste into syngas (gas mixture obtained from the gasification of biomass or carbon-based waste), through thermochemical processes such as gasification and pyrolysis.

For these processes, heat regulation is critical: the heat supplied to the process must be stable, precise, and available at high temperatures. The Tempco control unit is therefore designed to ensure the required temperature regulation with maximum levels of safety and operational continuity of the system.

Our TREG meets these requirements precisely:

  • It works with diathermic oil at high temperatures, ensuring proper thermal decomposition of the materials.
  • ATEX certification, essential in environments with potentially explosive atmospheres.
  • Remote control, which allows for remote management of process parameters, reducing on-site interventions and increasing operational continuity.

AI image illustrating a Tempco TREG thermoregulation unit used in a gasification and pyrolysis plant in waste treatment in line with circular economy principles.

From waste to Syngas: a closed cycle
TREG’s seamless integration into the project therefore represents a concrete example of circular economy applied to energy, with a green perspective and fostering sustainable energy transition:

  • Waste becomes a resource: materials that were previously a disposal cost are now transformed into an energy-rich gas.
  • The district becomes more self-sufficient, thanks to a process that recovers value from flows considered to be at their end-life cycle, achieving circularity.
  • Lower emissions and greater efficiency, because high-temperature thermoregulation makes the entire conversion cycle stable and reliable.
