Local context

Working in Jacobs

We service Jacobs Industrial and the surrounding blocks of Jacobs, 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

Evapco insulated floor slab installation in Jacobs

How fast can a technician service Evapco equipment at a potato & onion storage site in Jacobs?

Jacobs sits on the N2 and M4, so our Durban dispatch reaches most Jacobs Industrial sites inside a standard callout window. Emergency insulated floor slab installation runs 24/7 because condensation on bins causes rot spread through the stack.

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/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 GLOBALG.A.P. documentation your auditors expect.

What operating envelope do you commission this equipment to?

Potato & Onion Storage run at +4 °C to +10 °C at 85–95% RH, with insulated floor slab installation performed against Design to −30 °C with MHE loading. Condensation on bins causes rot spread through the stack
