Local context
Working in Olifantsfontein
We service Olifantsfontein Industrial and the surrounding blocks of Olifantsfontein, Midrand, with access off the R21 and N1. Highveld summers push afternoon ambients past 32 °C with heavy thunderstorm humidity, so condensers here are sized with a generous approach and cleaned before every summer.

FAQ
Danfoss process chiller maintenance in Olifantsfontein
How fast can a technician service Danfoss equipment at a airfreight perishable handling site in Olifantsfontein?
Olifantsfontein sits on the R21 and N1, so our Midrand dispatch reaches most Olifantsfontein Industrial sites inside a standard callout window. Emergency process chiller maintenance runs 24/7 because ramp exposure breaks the chain before uplift.
Do you stock OEM components for Danfoss systems?
Yes — Danfoss ETS/TES valve bodies, AKS 32R transmitters and EKC 202 controllers. Danfoss (Denmark) equipment on R134a/R744/R449A charges is supported with the fast-moving spares held at our Pretoria North workshop and non-stock items brought in on OEM order.
What pressure testing and gas compliance certificates are provided?
Every process chiller maintenance job closes with a pressure test record and gas handling Certificate of Conformance issued under SANS 10147 by a SAQCC Gas registered technician, plus the IATA PCR documentation your auditors expect.
What operating envelope do you commission this equipment to?
Airfreight Perishable Handling run at +2 °C to +8 °C at 85–90% RH, with process chiller maintenance performed against −20 °C to +15 °C process supply. Ramp exposure breaks the chain before uplift
