Cold season is coming. So be aware of freezing temperatures of antifreeze solutions in you thermoregulating and cooling plants, heat exchangers, free coolers for endothermic engines and overall in machines employing hydraulic circuits.
To avoid expensive and unwanted bursting and damages, here’s a useful technical table from the Resources section in Tempco site with freezing temperatures of some of the most employed antifreeze solutions.
