Local context
Working in Silverton
We service Silverton Industrial, Waltloo and the surrounding blocks of Silverton, Pretoria, with access off the N4 and R104. 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 insulated floor slab installation in Silverton
How fast can a technician service Evapco equipment at a seafood processing & fisheries site in Silverton?
Silverton sits on the N4 and R104, so our Pretoria dispatch reaches most Silverton Industrial sites inside a standard callout window. Emergency insulated floor slab installation 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 insulated floor slab installation 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 insulated floor slab installation performed against Design to −30 °C with MHE loading. Slow freezing forms large ice crystals and ruins texture
