MUENR-H4 Series
Industrial Range
Inverter Water Chiller MUENR-H4 Series
DC Inverter fan motor and compressor
All range units incorporate a DC Inverter fan motor and a compressor, in this way performance is improved in middle frequencies and ensure a more sensitive and effective control.
Hydraulic module
Module fully integrated and equipped with hydraulic components and expansion tank, plate-type heat exchanger and circulation pump.
Plate-type heat exchanger
The plate-type heat exchanger is made of stainless steel AISI 316 to ensure high efficiency of thermal exchange. It is also equipped with an electrical heater and a pressure differential switch.
High accuracy refrigerant flow control
Thanks to the electronic expansion valve (EXV) that maximizes performance and minimizes the impact of defrost. Precise and stable control of the refrigerant. The EXV control valve allows to adjust the flow accurately, monitor temperature and create an atmosphere of comfort.
Wide working temperature range
The MUENR-H4 equipments can operate in extreme temperatures, in heating mode up to an outside temperature of -15 °C and in cooling mode up to 46 °C.
Energy saving and high reliability
Thanks to the plate heat exchanger and high efficiency compressor and fan Inverter DC motor, power consumption is reduced and the unit operation is optimized.
Built-in control panel
All series units incorporate an electronic control panel that lets you adjust all operating parameters.
Moreover, in the models MUENR-10/12/14/16-H4, there is the possibility to connect a wall-mounted wire control (CL92340).
