Climate control, commercial refrigeration and mechanical services for retail, hospitality and industrial operations — delivered from the Eastern Cape, held to one group engineering standard.

The South Africa operation
Engineering built on cold-chain reality
The South African operation runs from the Eastern Cape, with teams based in Queenstown (Komani), East London and Mthatha. The work started in commercial refrigeration — cold rooms, display cases and the systems that keep stock sellable — and has grown into full climate and mechanical services.
That background shapes how we approach everything: temperature stability, plant reliability and maintenance access are not features, they are the job.
Retail floors, hotel kitchens, warehouses and offices all get the same process — survey first, engineer to the duty, install to the drawing, prove it before handover.

What we deliver locally
From walk-in cold rooms to full building climate systems.
02
Air Conditioning
Split, multi-split, VRF and packaged cooling solutions specified to the building and its duty.

HVAC Systems
Design, supply, installation and commissioning of complete HVAC systems for new build and refurbishment.
Discuss with the SA team04
Ventilation
Supply, extract and mechanical ventilation, including air handling, for occupied and process spaces.
Discuss with the SA team05
HVAC Maintenance
Planned preventative maintenance, fault response and system optimisation across the installed base.
Discuss with the SA team06
Mechanical Services
Coordinated building mechanical services — plant, distribution, controls and interfaces with other trades.
Discuss with the SA teamHow we work locally
Keeping operations running while we work
Stores trade, kitchens cook and warehouses dispatch while we install. Works are sequenced around operations — staged cutovers, out-of-hours commissioning and redundant capacity where the job demands it.
- 01
Survey on site
Loads, ambient conditions, existing plant and stock/occupancy constraints recorded first.
- 02
Engineer to the duty
Plant sized for South African ambient conditions and real usage — not catalogue figures.
- 03
Install around operations
Phased execution with cutovers planned so trading, cooking or dispatch continues.
- 04
Verify & maintain
Temperature and performance verified at handover, then protected by planned maintenance.
