Alper-010 Heated Clamps

Alper heated clamping bands are characterized by a solid construction. The efficient knurled steel strap with a tensioning system allows for easy installation. It can be used in environments where a high IP class is required.

Heated clamping bands show excellent mechanical and electrical reliability both at high and low temperatures.

Application and advantages of heated clamping bands

The use of heated clamping bands proves to be essential for maintaining the ideal functioning of the compressor. The Alper crankcase heater is a solution that adapts to all needs. It prevents bearing stress and facilitates engine start-up.

The use of a screw-in tension hook not only enables quick installation but also ensures excellent adhesion of the compressor crankcase heater, and thus ideal heat exchange with the compressor.

It is also possible to produce this crankcase heater according to customer specifications, with power cables of various lengths, resistant to UV rays and low temperatures.

The compressor crankcase heater can be equipped with protective thermostats and thermal fuses. Additionally, metal terminals or other connectors can be supplied at the customer's request.
