FAQ
Copeland temperature mapping & validation in Letsitele
How fast can a technician service Copeland equipment at a grain & seed 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 temperature mapping & validation runs 24/7 because insect activity and germination loss above 18 °c.
Do you stock OEM components for Copeland systems?
Yes — Copeland scroll sets, CoreSense modules, crankcase heaters and POE oil charges. Copeland (USA) equipment on R404A/R134a 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 GLOBALG.A.P. documentation your auditors expect.
What operating envelope do you commission this equipment to?
Grain & Seed Storage run at +10 °C to +18 °C at 50–60% RH, with temperature mapping & validation performed against Client setpoint band, typically +2 °C to +8 °C. Insect activity and germination loss above 18 °C
