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

Alfa Laval glycol chiller installation in Letsitele

How fast can a technician service Alfa Laval equipment at a potato & onion storage 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 glycol chiller installation runs 24/7 because condensation on bins causes rot spread through the stack.

Do you stock OEM components for Alfa Laval systems?

Yes — Alfa Laval plate packs, gaskets and cleaning-in-place chemistry. Alfa Laval (Sweden) equipment on R717/R404A 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 glycol chiller 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 GLOBALG.A.P. documentation your auditors expect.

What operating envelope do you commission this equipment to?

Potato & Onion Storage run at +4 °C to +10 °C at 85–95% RH, with glycol chiller installation performed against −8 °C to +4 °C glycol supply. Condensation on bins causes rot spread through the stack
