Working in Tzaneen Industrial
We service Tzaneen Industrial, Letsitele packing precinct and the surrounding blocks of Tzaneen Industrial, Tzaneen, with access off the R71 and R36. Long, hot lowveld summers regularly exceed 36 °C, so high-ambient head pressure control and shaded plant rooms are non-negotiable.

FAQ
Danfoss variable speed drive installation in Tzaneen Industrial
How fast can a technician service Danfoss equipment at a flower & floristry coolers site in Tzaneen Industrial?
Tzaneen Industrial sits on the R71 and R36, so our Tzaneen dispatch reaches most Tzaneen Industrial sites inside a standard callout window. Emergency variable speed drive installation runs 24/7 because ethylene build-up and desiccation shorten vase life.
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 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 SANS 10147 documentation your auditors expect.
What operating envelope do you commission this equipment to?
Flower & Floristry Coolers run at +1 °C to +4 °C at 85–90% RH, with variable speed drive installation performed against Turndown to 30% of rated duty. Ethylene build-up and desiccation shorten vase life
