FreezGard Self-Regulating Crankcase Heater for Refrigeration Compressors

Introduction

Crankcase heaters are designed for use with refrigeration compressors up to 5 HP and 40 inches or less in circumference. The heaters should be used in non-hazardous areas. The self-regulating cable provides peak heat during cold periods and reduced heat when the air temperature rises.

When compressors operate in cold areas, refrigerant can migrate into the crankcase oil whenever the compressor is not running. On start-up, this can cause excessive motor wear and a loss of refrigeration efficiency.

FreezGard self-regulating crankcase heaters provide reliable peak heating during critical cold periods and, unlike conventional constant-wattage heaters, reduce their heating once the compres-sor starts up or the air temperature rises. Also, self-regulating heaters can be safely overlapped and closely spaced without burning out; So one size fits all hermetic compressors up to 5 HP that are 40 inches or less in circumference.
