Description
The Mars 33455 is a refrigeration thermostat engineered for dependable temperature switching in commercial and light commercial refrigeration applications. With a fixed open setpoint of 20°F and a close setpoint of 60°F, this thermostat provides a wide operating differential that makes it well suited for defrost termination, evaporator fan control, and other refrigeration temperature-sensing duties where precise cut-in and cut-out points are essential.
Key Features
- Opens at 20°F — breaks the circuit at low-temperature setpoint for reliable refrigeration protection
- Closes at 60°F — re-engages the circuit as temperature rises, enabling automatic defrost termination or fan cycling
- Wide temperature differential for stable, chatter-free switching in refrigeration environments
- Compact, durable construction designed to withstand the demands of refrigeration systems
- Direct replacement for compatible refrigeration thermostat applications
Typical Applications
- Defrost termination control in walk-in coolers and reach-in refrigeration units
- Evaporator fan cycling and temperature limit control
- Commercial refrigeration equipment temperature management
- Light commercial refrigeration OEM and service replacement
