Local context
Working in Secunda Industrial
We service Secunda Industrial Complex and the surrounding blocks of Secunda Industrial, Secunda, with access off the N17 and R546. Lowveld heat and escarpment humidity combine into high wet-bulb loads through the citrus and subtropical pack season.

FAQ
Danfoss temperature mapping & validation in Secunda Industrial
How fast can a technician service Danfoss equipment at a mining & bulk air cooling site in Secunda Industrial?
Secunda Industrial sits on the N17 and R546, so our Secunda dispatch reaches most Secunda Industrial Complex sites inside a standard callout window. Emergency temperature mapping & validation 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 temperature mapping & validation 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 temperature mapping & validation performed against Client setpoint band, typically +2 °C to +8 °C. Underground heat stress limits shift productivity
