Bitzer screw, semi-hermetic and reciprocating compressor service and rebuilds.
Overview
Bitzer compressors sit inside a huge share of the packaged chillers, process cooling skids and industrial heat pumps in South Africa. We rebuild, replace and re-commission Bitzer screw and semi-hermetic compressors, including CM-SW / CM-RC protection module work and oil management.

Troubleshooting
Tap a fault for likely causes, what to check on site, and when to call us out.
Likely causes
What to check
Read the LED fault code on the module before resetting and check motor PTC resistance.
When to call us
Repeated module trips mean the compressor is being run outside its envelope — call us to fix the cause, not the symptom.
Likely causes
What to check
Check the oil sight glass level at steady state and inspect the separator drain line temperature.
When to call us
Oil in the evaporator kills capacity — book a service before you chase a phantom refrigerant problem.
Likely causes
What to check
Do an oil analysis and log vibration at the bearing housings.
When to call us
Bitzer publishes rebuild hour intervals — call us to schedule a rebuild rather than run to failure.
Parts & Spares
Bitzer is well stocked in South Africa through authorised distributors. Gaskets, valve plates, oil and protection modules are usually same-week; complete screw rotor sets and reman compressors run 3 – 6 weeks.

Yes — we source OEM parts through South African distributors wherever the part is still catalogued. Where a component is obsolete or on long lead time, we offer a tested equivalent and tell you up front which route we are taking and what it does to the warranty.
Absolutely. Most of the Bitzer plant we look after in Gauteng is well past its warranty period. We service, rebuild and re-commission older units rather than pushing you straight into a replacement.
We work with the unit controller and integrate it with BACnet, Modbus or your existing BMS head-end. That includes alarm mapping, trending, setpoint scheduling and getting fault history off the panel so we can see what actually tripped.
Same-day across Johannesburg, Pretoria, the East Rand, West Rand and the Vaal Triangle. Mpumalanga, North West, Free State and Limpopo are typically next-day, sooner for critical plant.
