Local context
Working in Halfway House
We service Halfway House Industrial and the surrounding blocks of Halfway House, Midrand, with access off the N1 and R101. 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
Evapco freezer room construction in Halfway House
How fast can a technician service Evapco equipment at a seafood processing & fisheries site in Halfway House?
Halfway House sits on the N1 and R101, so our Midrand dispatch reaches most Halfway House Industrial sites inside a standard callout window. Emergency freezer room construction runs 24/7 because slow freezing forms large ice crystals and ruins texture.
Do you stock OEM components for Evapco systems?
Yes — Evapco spray nozzles, drift eliminators, fan drives and water treatment kits. Evapco (USA) equipment on R717/R744/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 freezer room construction 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 freezer room construction performed against −18 °C to −25 °C room design. Slow freezing forms large ice crystals and ruins texture
