Local context
Working in Markman
We service Markman Industrial and the surrounding blocks of Markman, Gqeberha, with access off the N2 and R335. Coastal salt-laden air plus wide day-night temperature swings demand coated coils and tight vapour barriers.

FAQ
Danfoss temperature mapping & validation in Markman
How fast can a technician service Danfoss equipment at a airfreight perishable handling 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 temperature mapping & validation runs 24/7 because ramp exposure breaks the chain before uplift.
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 R134a/R744/R449A 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 temperature mapping & validation 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 IATA PCR documentation your auditors expect.
What operating envelope do you commission this equipment to?
Airfreight Perishable Handling run at +2 °C to +8 °C at 85–90% RH, with temperature mapping & validation performed against Client setpoint band, typically +2 °C to +8 °C. Ramp exposure breaks the chain before uplift
