FAQ

Alfa Laval energy retrofit & optimisation in Markman

How fast can a technician service Alfa Laval equipment at a data centre & critical cooling site in Markman?

Markman sits on the N2 and R335, so our Gqeberha dispatch reaches most Markman Industrial sites inside a standard callout window. Emergency energy retrofit & optimisation runs 24/7 because thermal runaway trips racks within minutes.

Do you stock OEM components for Alfa Laval systems?

Yes — Alfa Laval plate packs, gaskets and cleaning-in-place chemistry. Alfa Laval (Sweden) equipment on R744/R134a 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 energy retrofit & optimisation 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 ASHRAE TC9.9 documentation your auditors expect.

What operating envelope do you commission this equipment to?

Data Centre & Critical Cooling run at +18 °C to +27 °C supply air at 40–60% RH, with energy retrofit & optimisation performed against Plant-wide kWh reduction of 15–35%. Thermal runaway trips racks within minutes
