Replace a belt-driven compressor and retain the factory A/C circuit

VEHICLE UPGRADES

Replace a belt-driven compressor and retain the factory A/C circuit

An electric compressor can drive an existing circuit, but it is not a universal plug-in replacement. The original heat exchangers, metering device, oil management, controls and pressure protection must be checked as one system.

BEST STARTING POINT

An MD-series or enclosed compressor drive selected for the circuit capacity, supply voltage and control strategy, with new mounting, power and safety hardware.

SYSTEM APPROACH

How this comes together

01

Retain

Keep the factory evaporator, condenser and cabin controls only when their capacity, refrigerant and condition are suitable.

02

Replace

Remove the belt compressor and adapt the suction/discharge lines to the selected electric compressor.

03

Protect

Retain or add high/low-pressure protection, condenser-fan control, thermostat demand and correctly sized fuse/cabling.

BEFORE BUYING

  • Original vehicle and donor A/C details
  • Refrigerant and compressor oil type
  • Original compressor displacement or cooling duty
  • Hose sizes and connection details
  • System voltage and available continuous current
  • Factory pressure-switch and thermostat logic
