FAQ
Danfoss plc & controller programming in De Aar Industrial
How fast can a technician service Danfoss equipment at a mining & bulk air cooling site in De Aar Industrial?
De Aar Industrial sits on the N10 and N12, so our De Aar dispatch reaches most De Aar Industrial sites inside a standard callout window. Emergency plc & controller programming runs 24/7 because underground heat stress limits shift productivity.
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/R717 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 plc & controller programming 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 MHSA documentation your auditors expect.
What operating envelope do you commission this equipment to?
Mining & Bulk Air Cooling run at +2 °C to +12 °C chilled water at 90–100% RH, with plc & controller programming performed against Full plant control range. Underground heat stress limits shift productivity
