FAQ
Danfoss variable speed drive installation in Parow Industria
How fast can a technician service Danfoss equipment at a airfreight perishable handling site in Parow Industria?
Parow Industria sits on the N1 and R300, so our Cape Town dispatch reaches most Parow Industria sites inside a standard callout window. Emergency variable speed drive installation 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 variable speed drive installation 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 variable speed drive installation performed against Turndown to 30% of rated duty. Ramp exposure breaks the chain before uplift
