R-134a or R-449A refrigerant, other refrigerants by request.
Hermetic reciprocating compressor mounted on shock absorbers, with discharge muffler and internal klixon.
High performance condensing coil in copper pipes and aluminium fins.
Centrifugal motor fan with available static pressure for a ducted outlet of condenser hot air (centrifugal version).
Refrigerati on circuit equipped with HP and LP switches, filter dryer, liquid receiver and sight gauge.
Digital control of condensation pressure with the optional electrical board, and all-nothing condensation control with condensers without electrical panel.
Proportional control of condensing pressure through fan speed variation (included in MDH series 4).
Full control and power board with compressor and motor fan protection.
Electronic regulation with evaporator control pad (-N version with optional electrical board).
Built-in oil separator (-V multi -service version).
Liquid injection system for negative temperature models with R-449A.
Refrigerant gas not included
N versions: Without electronic controller: designed for the control of stop / start due to low pressure (drop due to low or pump down).
V version (multi -service): The multi -service version features VRC system to adjust the refrigerant flow to the demand of the evaporators, keeping the pressure constant in suction the line.
The VRC system is composed of a set of pressure and temperature regulation valves to progressively modulate cooling capacity from 100 % to 10 % of its nominal capacity, while reducing energy consumption and preventing compressor overheating
