Working in Nuffield

FAQ
Danfoss refrigerant leak detection in Nuffield
How fast can a technician service Danfoss equipment at a convenience & forecourt retail site in Nuffield?
Nuffield sits on the N17 and R29, so our Springs dispatch reaches most Nuffield Industrial sites inside a standard callout window. Emergency refrigerant leak detection runs 24/7 because unattended failure overnight loses the full chiller line.
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 refrigerant leak detection 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 R638 documentation your auditors expect.
What operating envelope do you commission this equipment to?
Convenience & Forecourt Retail run at −18 °C to +6 °C at 50–60% RH, with refrigerant leak detection performed against System-dependent, tested to design pressure. Unattended failure overnight loses the full chiller line
