FAQ
Danfoss humidity control systems in Markman
How fast can a technician service Danfoss equipment at a citrus packhouses site in Markman?
Markman sits on the N2 and R335, so our Gqeberha dispatch reaches most Markman Industrial sites inside a standard callout window. Emergency humidity control systems runs 24/7 because cold-treatment temperature drift fails an entire export consignment.
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 GLOBALG.A.P. documentation your auditors expect.
What operating envelope do you commission this equipment to?
Citrus Packhouses run at −0.6 °C to +8 °C at 90–95% RH, with humidity control systems performed against 45–95% RH depending on product. Cold-treatment temperature drift fails an entire export consignment
