Industrial Heat Pump Repairs in Johannesburg & Gauteng

High-capacity and cascade heat pump repairs for plants and process water.

Industrial heat pump plant is usually multi-module, three phase and tied into a buffer or calorifier bank. Repairs have to account for staged control, flow balancing across modules and the fact that the plant normally cannot be shut down for long. We work off pressure and temperature logs before touching the refrigerant circuit.

Related faults we diagnose

Heat Pump Not Heating Water

The unit runs but water stays cold or only reaches lukewarm temperatures.

Heat Pump Keeps Tripping the Breaker

The circuit breaker or earth leakage trips shortly after the heat pump starts.

Heat Pump Leaking Water

Water pooling under or around the unit, sometimes continuously.

Heat Pump Making Noise

Rattling, grinding, screeching or loud humming during operation.

Heat Pump Compressor Fault

The compressor will not start, hums and trips, or cuts out on overload.

Heat Pump High Pressure Fault

The unit locks out on a high pressure error, often after running for a while.

Heat Pump Low Pressure Fault

The unit trips on low pressure, typically in cold weather or early morning.

Heat Pump Icing Up

Ice forms on the evaporator coil and does not clear between cycles.

Additional work is quoted before it is carried out.

Which faults do you see most often in Johannesburg?

On heat pumps in this area the recurring issues are heat pump high pressure fault, heat pump low pressure fault, heat pump icing up. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.
