Description

The bench STE 130 allows the study of a heat pump air/water reversible. The circuit is composed of a hermetic compressor, a plate heat exchanger (water), a forced air exchanger (air), a set of 4 valves allowing the reversibility of the cycle and all the accessories necessary for the operation and the study. The bench is supply with an auxiliary module including a water tank and a ventilated exchanger to dissipate the calories produced.

The electric box includes a PLC managing the operation and display the measurement. The signals from the sensors are transferred to dual well terminals opposite for external use.

The robust design of this device makes it suitable for use in schools.
The equipment is set up on an Anodized aluminium frame on casters wheels. This gives it great strength and a flexibility of integration into your premises.
The manufacture of this equipment complies with the European standard for machinery manufacturing.

The bench is installed on an aluminium profile structure equipped with four non slip feet.

It includes an electrical box with general power disconnector and 30mA differential circuit breaker
