Local context
Working in Howick Industrial
We service Howick Industrial and the surrounding blocks of Howick Industrial, Howick, with access off the N3 and R103. Sub-tropical coastal humidity keeps wet-bulb temperatures high year-round, which raises evaporative condenser duty and accelerates coil corrosion.

FAQ
Sabroe plc & controller programming in Howick Industrial
How fast can a technician service Sabroe equipment at a mining & bulk air cooling site in Howick Industrial?
Howick Industrial sits on the N3 and R103, so our Howick dispatch reaches most Howick 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 Sabroe systems?
Yes — Sabroe valve kits, Unisab control boards and oil separators. Sabroe (Denmark) equipment on R717/R744/R134a 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
