FAQ
Danfoss data logging & alarm systems in Markman
How fast can a technician service Danfoss equipment at a vaccine cold chain facilities 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 data logging & alarm systems runs 24/7 because loss of ultra-low storage destroys irreplaceable stock.
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 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 data logging & alarm 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 SAHPRA GDP documentation your auditors expect.
What operating envelope do you commission this equipment to?
Vaccine Cold Chain Facilities run at +2 °C to +8 °C and −20 °C / −70 °C at 45–60% RH, with data logging & alarm systems performed against Continuous logging at 1–15 minute intervals. Loss of ultra-low storage destroys irreplaceable stock
