R-134a or R-449A refrigerant, other refrigerants by request.
Reciprocating hermetic compressor, acoustically insulated with discharge muffler, mounted on shock absorbers, with crankcase heater and internal klixon.
Large-surface condensing coil made of copper tubes and aluminium fins, with tropicalised dimensioning for ambient temperatures up to 50 °C.
Low speed axial motor fan.
Refrigeration circuit equipped with high and low pressure switches, ceramic filter and sight gauge.
Digital control of condensation pressure with the optional electrical board, and all-nothing condensation control in condensers without electrical panel.
Proportional control of condensing pressure through fan speed variation (included from MDF-NY-2086 and MDF-NG-1038 without electronic control).
Full control and power board with compressor and motor fan protection.
Liquid injection system for negative temperature models with R-449A.
Gas refrigerant not included.
N version. Without electrical board. Designed for on/off operation depending on the suction pressure (pump-down).
With electrical board as an option. Electronic controller to manage the condensing unit and the evaporator built-in solenoid valve as an option.
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 control valves to progressively modulate cooling capacity from 100 % to 10 % of its nominal capacity, while reducing energy consumption and preventing compressor overheating.
