Local context
Working in Letsitele
We service Letsitele packhouse precinct and the surrounding blocks of Letsitele, Tzaneen, with access off the R71 and R529. Long, hot lowveld summers regularly exceed 36 °C, so high-ambient head pressure control and shaded plant rooms are non-negotiable.

FAQ
Carel process chiller maintenance in Letsitele
How fast can a technician service Carel equipment at a supermarket central distribution 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 process chiller maintenance runs 24/7 because rack failure halts store replenishment across a region.
Do you stock OEM components for Carel systems?
Yes — Carel EVD Evolution drivers, NTC/ratiometric probes and pGD terminals. Carel (Italy) equipment on R404A/R744/R448A 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 process 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?
Supermarket Central Distribution run at −25 °C to +12 °C multi-temp at 80–90% RH, with process chiller maintenance performed against −20 °C to +15 °C process supply. Rack failure halts store replenishment across a region
