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

Evapco spray foam insulation in Letsitele

How fast can a technician service Evapco equipment at a reefer container depots 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 a failed pti holds the box and the booking.

Do you stock OEM components for Evapco systems?

Yes — Evapco spray nozzles, drift eliminators, fan drives and water treatment kits. Evapco (USA) equipment on 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 SANS 10147 documentation your auditors expect.

What operating envelope do you commission this equipment to?

Reefer Container Depots run at −30 °C to +12 °C at 80–90% RH, with spray foam insulation performed against Applied thickness 25–150 mm. A failed PTI holds the box and the booking
