Heatcraft Refrigeration 5857A Terminal Block On Air Defrost

The Heatcraft Refrigeration 5857A Terminal Block on Air Defrost is an essential part used in HVAC systems particularly associated with refrigeration units having defrosting of air. The secure electrical connections offered by this terminal block make defrost cycles in refrigeration systems run smoothly. It minimizes ice buildup on evaporator coils by managing power flow to defrost heaters efficiently so that they are only used when they are indicated by the sensor and only as small portions of the evaporator time are defrosted or freeze dried as necessary. Used commonly in commercial refrigeration, freezer units and cold storage systems, it improves energy efficiency, minimizes downtime and extends the equipment longevity, while providing reliable and cost effective operation in demanding environments.
