REFRIGERATION CONTROLLERS
T4031, T6031
For limit or temperature control in refrigerated areas where remote mounting
of sensing element is required.
• Liquid-filled copper elements provide rapid sensing to control the
compressor system.
• Control temperature in a duct, tank, freezer or cooler.
• Controller element can be directly immersed in the controlled medium.
• Adjustable control setpoint.
• Ambient temperature compensation provides good temperature control.
