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.
Rapid 4-hour pull-down windows after field heat arrival Slow pull-down causes SO₂ pad burn and berry shatter

FAQ
Carel temperature mapping & validation in Letsitele
How fast can a technician service Carel equipment at a table grape packhouses 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 temperature mapping & validation runs 24/7 because slow pull-down causes so₂ pad burn and berry shatter.
Do you stock OEM components for Carel systems?
Yes — Carel EVD Evolution drivers, NTC/ratiometric probes and pGD terminals. Carel (Italy) equipment on 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 temperature mapping & validation 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 PPECB documentation your auditors expect.
What operating envelope do you commission this equipment to?
Table Grape Packhouses run at −0.5 °C to +1 °C at 90–95% RH, with temperature mapping & validation performed against Client setpoint band, typically +2 °C to +8 °C. Slow pull-down causes SO₂ pad burn and berry shatter
