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
Alfa Laval energy retrofit & optimisation in Jacobs
How fast can a technician service Alfa Laval equipment at a reefer container depots 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 energy retrofit & optimisation runs 24/7 because a failed pti holds the box and the booking.
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 SANS 10147 documentation your auditors expect.
What operating envelope do you commission this equipment to?
Reefer Container Depots run at −30 °C to +12 °C at 80–90% RH, with energy retrofit & optimisation performed against Plant-wide kWh reduction of 15–35%. A failed PTI holds the box and the booking
