FAQ

Danfoss packhouse chiller maintenance in Markman

How fast can a technician service Danfoss equipment at a cheese maturation rooms 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 packhouse chiller maintenance runs 24/7 because humidity swings crack rinds and stall ripening.

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/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 packhouse chiller maintenance 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?

Cheese Maturation Rooms run at +8 °C to +14 °C at 80–90% RH, with packhouse chiller maintenance performed against −1 °C to +8 °C room design. Humidity swings crack rinds and stall ripening
