Local context
Working in Mobeni
We service Mobeni Industrial and the surrounding blocks of Mobeni, Durban, with access off the N2 and M4. Sub-tropical coastal humidity keeps wet-bulb temperatures high year-round, which raises evaporative condenser duty and accelerates coil corrosion.

FAQ
Copeland thermostatic expansion valve diagnostics in Mobeni
How fast can a technician service Copeland equipment at a macadamia processing site in Mobeni?
Mobeni sits on the N2 and M4, so our Durban dispatch reaches most Mobeni Industrial sites inside a standard callout window. Emergency thermostatic expansion valve diagnostics runs 24/7 because moisture pickup drives rancidity and kernel downgrade.
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 thermostatic expansion valve diagnostics 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?
Macadamia Processing run at +8 °C to +15 °C at 55–65% RH, with thermostatic expansion valve diagnostics performed against −40 °C to +10 °C evaporating. Moisture pickup drives rancidity and kernel downgrade
