Description
The Lennox 93M09 is a crankcase heater belt used specifically to maintain the right operating temperature of crankcase oil in HVAC equipment. it is a jacket that surrounds the crankcase and turns electrical energy into heat. This heat is then transferred to the oil so as to avoid thickening of the same in cold climates. Thicker oil reduces the ease with which the equipment can pump the oil and this may cause some of the equipment to wear out. Crankcase heater belts are utilized in air handling unit, rooftop unit and chillers. Advantages of the crankcase heater belt are better circulation of oil, less wear and tear of the crankcase and other parts, and easier starting of the HVAC equipment.
