Local context
Working in Apex
We service Apex Industrial and the surrounding blocks of Apex, Benoni, with access off the N12 and R23. 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 Apex
How fast can a technician service Danfoss equipment at a third-party cold storage (3pl) site in Apex?
Apex sits on the N12 and R23, so our Benoni dispatch reaches most Apex Industrial sites inside a standard callout window. Emergency humidity control systems runs 24/7 because a single plant outage puts several clients' stock at risk.
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/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 HACCP documentation your auditors expect.
What operating envelope do you commission this equipment to?
Third-Party Cold Storage (3PL) run at −25 °C to +4 °C at 85–90% RH, with humidity control systems performed against 45–95% RH depending on product. A single plant outage puts several clients' stock at risk
