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
Isocab spray foam insulation in Letsitele
How fast can a technician service Isocab equipment at a seafood processing & fisheries 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 spray foam insulation runs 24/7 because slow freezing forms large ice crystals and ruins texture.
Do you stock OEM components for Isocab systems?
Yes — Isocab panel joints, door sets and hygienic coving. Isocab (Belgium) equipment on R404A/R717/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 spray foam insulation 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?
Seafood Processing & Fisheries run at −40 °C blast to −25 °C hold at 85–95% RH, with spray foam insulation performed against Applied thickness 25–150 mm. Slow freezing forms large ice crystals and ruins texture
