Corrosion Resistant Construction: The stainless steel diaphragm and capillary tube are engineered for longevity in high-moisture industrial environments
Industrial Durability: Rated for high-temperature media and high-pressure differentials
The brushed metal look plate provides a durable finish that meets NEC requirements while the teeter-type terminals simplify field wiring
using it with higher-pressure refrigerants like R-410A will result in incorrect trip points and potential system damage
Using it with other refrigerants will lead to incorrect superheat and potential system failure
Trane CNT2237 Defrost Controller Refrigerant Corrosion Resistant Construction: The stainlessThe Trane CNT2237 Defrost Controller is a high precision OEM electronic board engineered for demand based defrost management in specialized Trane heat pump systems. As a veteran grade HVAC replacement part, this 24V AC controller replaces legacy boards by utilizing advanced adaptive control logic to monitor evaporator coil temperatures. Unlike standard time and temperature units, the CNT2237 uses localized sensor data to initiate the defrost cycle
