Local context
Working in Briardene
We service Briardene Industrial and the surrounding blocks of Briardene, Durban, with access off the N2 and M12. Sub-tropical coastal humidity keeps wet-bulb temperatures high year-round, which raises evaporative condenser duty and accelerates coil corrosion.

FAQ
Danfoss plc & controller programming in Briardene
How fast can a technician service Danfoss equipment at a potato & onion storage site in Briardene?
Briardene sits on the N2 and M12, so our Durban dispatch reaches most Briardene Industrial sites inside a standard callout window. Emergency plc & controller programming runs 24/7 because condensation on bins causes rot spread through the stack.
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 R404A/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 GLOBALG.A.P. documentation your auditors expect.
What operating envelope do you commission this equipment to?
Potato & Onion Storage run at +4 °C to +10 °C at 85–95% RH, with plc & controller programming performed against Full plant control range. Condensation on bins causes rot spread through the stack
