Local context
Working in Kramerville
We service Kramerville Industrial and the surrounding blocks of Kramerville, Sandton, with access off the M1 and N3. Highveld summers push afternoon ambients past 32 °C with heavy thunderstorm humidity, so condensers here are sized with a generous approach and cleaned before every summer.

FAQ
Bitzer energy retrofit & optimisation in Kramerville
How fast can a technician service Bitzer equipment at a mining & bulk air cooling site in Kramerville?
Kramerville sits on the M1 and N3, so our Sandton dispatch reaches most Kramerville Industrial sites inside a standard callout window. Emergency energy retrofit & optimisation runs 24/7 because underground heat stress limits shift productivity.
Do you stock OEM components for Bitzer systems?
Yes — Genuine Bitzer valve plates, gasket sets, oil pumps and OLC-D1 protection modules. Bitzer (Germany) equipment on R134a/R744/R717 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 MHSA documentation your auditors expect.
What operating envelope do you commission this equipment to?
Mining & Bulk Air Cooling run at +2 °C to +12 °C chilled water at 90–100% RH, with energy retrofit & optimisation performed against Plant-wide kWh reduction of 15–35%. Underground heat stress limits shift productivity
