Product Description

Air-to-Water Heat Pump Operation Training Bench Unit

An Air-to-Water Heat Pump Operation Training Bench for studying the use of heat pumps to transfer heat from one source at a certain temperature to another source at a higher temperature.

The Air-to-Water Heat Pump Operation Training Bench Unit  is designed to allow students to gain both practical and theoretical knowledge of the operation of heat pumps.

The Air-to-Water Heat Pump Operation Training Bench Unit has been designed and manufactured to incorporate all current safety standards.

The refrigerant used complies with anti-pollution legislation.

Experiments
