Safe-T-Therm is an inhibited-propylene glycol designed to protect metals such as brass, copper, solder, steel and cast iron. The fluid’s formula also includes an orange dye for leak detection and an antifoam agent to minimize foaming during service. Using the propylene-glycol based fluid in place of brine solutions or uninhibited glycol/water solutions can lower maintenance costs and improves heat transfer efficiency.
