FAQ

Emerson variable speed drive installation in Wilsonia

How fast can a technician service Emerson equipment at a airfreight perishable handling site in Wilsonia?

Wilsonia sits on the N2 and N6, so our East London dispatch reaches most Wilsonia Industrial sites inside a standard callout window. Emergency variable speed drive installation runs 24/7 because ramp exposure breaks the chain before uplift.

Do you stock OEM components for Emerson systems?

Yes — Emerson Alco valve bodies, EXD drivers and supervisory licences. Emerson (USA) equipment on R134a/R744/R449A 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 variable speed drive 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 IATA PCR documentation your auditors expect.

What operating envelope do you commission this equipment to?

Airfreight Perishable Handling run at +2 °C to +8 °C at 85–90% RH, with variable speed drive installation performed against Turndown to 30% of rated duty. Ramp exposure breaks the chain before uplift
