FAQ
Danfoss co₂ transcritical service in Letsitele
How fast can a technician service Danfoss equipment at a quick service restaurant chains site in Letsitele?
Letsitele sits on the R71 and R529, so our Tzaneen dispatch reaches most Letsitele packhouse precinct sites inside a standard callout window. Emergency co₂ transcritical service runs 24/7 because kitchen downtime closes the store outright.
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 co₂ transcritical service 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?
Quick Service Restaurant Chains run at −20 °C to +4 °C at 50–60% RH, with co₂ transcritical service performed against −35 °C evaporating, 90–120 bar high side. Kitchen downtime closes the store outright
