Local context
Working in Croydon
We service Croydon Industrial and the surrounding blocks of Croydon, Kempton Park, with access off the R21 and N12. Highveld summers push afternoon ambients past 32 °C with heavy thunderstorm humidity, so condensers here are sized with a generous approach and cleaned before every summer.

FAQ
Güntner evaporator coil descaling in Croydon
How fast can a technician service Güntner equipment at a seafood processing & fisheries site in Croydon?
Croydon sits on the R21 and N12, so our Kempton Park dispatch reaches most Croydon Industrial sites inside a standard callout window. Emergency evaporator coil descaling runs 24/7 because slow freezing forms large ice crystals and ruins texture.
Do you stock OEM components for Güntner systems?
Yes — Güntner EC fan modules, defrost heaters and coil blocks. Güntner (Germany) equipment on R404A/R717/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 evaporator coil descaling 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?
Seafood Processing & Fisheries run at −40 °C blast to −25 °C hold at 85–95% RH, with evaporator coil descaling performed against −30 °C to +8 °C air-off. Slow freezing forms large ice crystals and ruins texture
