Local context
Working in Perseverance
We service Perseverance Industrial and the surrounding blocks of Perseverance, Gqeberha, with access off the N2 and R335. Coastal salt-laden air plus wide day-night temperature swings demand coated coils and tight vapour barriers.

FAQ
Güntner forced-air pre-cooling systems in Perseverance
How fast can a technician service Güntner equipment at a seafood processing & fisheries site in Perseverance?
Perseverance sits on the N2 and R335, so our Gqeberha dispatch reaches most Perseverance Industrial sites inside a standard callout window. Emergency forced-air pre-cooling systems 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 forced-air pre-cooling systems 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 forced-air pre-cooling systems performed against −1 °C to +4 °C air-off at high airflow. Slow freezing forms large ice crystals and ruins texture
