Veris Industries TZ502M 2-SPDT Relay M/R Freeze Stat W/50' Copper Tubing

The Veris Industries TZ502M 2 SPDT Relay Manual Reset Freeze Stat with 50-foot copper tubing is a temperature protection control used to protect cooling coils. It continuously monitors air temperature across the coil using a capillary sensing element and activates when temperatures approach in HVAC systems. It is placed between the heating and cooling coils within air handling units, and it can interrupt equipment operation or trigger protective control sequences. It integrates with building control circuits to protect coils, piping, and associated components maintain consistent operation and preventing damage caused by low-temperature conditions.
