Local context
Working in Aeroton
We service Aeroton Industrial and the surrounding blocks of Aeroton, Johannesburg, with access off the N1 and N12 and M1. 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 humidity control systems in Aeroton
How fast can a technician service Danfoss equipment at a mining & bulk air cooling site in Aeroton?
Aeroton sits on the N1 and N12 and M1, so our Johannesburg dispatch reaches most Aeroton Industrial sites inside a standard callout window. Emergency humidity control systems 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 humidity control systems 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 humidity control systems performed against 45–95% RH depending on product. Underground heat stress limits shift productivity
