Local context
Working in Stanger Industrial
We service Stanger Industrial and the surrounding blocks of Stanger Industrial, KwaDukuza, with access off the N2 and R102. Sub-tropical coastal humidity keeps wet-bulb temperatures high year-round, which raises evaporative condenser duty and accelerates coil corrosion.

FAQ
Danfoss humidity control systems in Stanger Industrial
How fast can a technician service Danfoss equipment at a potato & onion storage site in Stanger Industrial?
Stanger Industrial sits on the N2 and R102, so our KwaDukuza dispatch reaches most Stanger Industrial sites inside a standard callout window. Emergency humidity control systems 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 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 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 humidity control systems performed against 45–95% RH depending on product. Condensation on bins causes rot spread through the stack
