Local context
Working in Modderfontein
We service Modderfontein Industrial and the surrounding blocks of Modderfontein, Johannesburg, with access off the N3 and R25. 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
Bock screw compressor service in Modderfontein
How fast can a technician service Bock equipment at a ice cream & frozen dessert plants site in Modderfontein?
Modderfontein sits on the N3 and R25, so our Johannesburg dispatch reaches most Modderfontein Industrial sites inside a standard callout window. Emergency screw compressor service runs 24/7 because heat shock during hardening causes ice crystal growth.
Do you stock OEM components for Bock systems?
Yes — Bock shaft seals, suction filters and gasket kits. Bock (Germany) equipment on R404A/R717/R744 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 screw compressor service 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 HACCP documentation your auditors expect.
What operating envelope do you commission this equipment to?
Ice Cream & Frozen Dessert Plants run at −30 °C to −25 °C at 80–85% RH, with screw compressor service performed against −45 °C to +5 °C evaporating. Heat shock during hardening causes ice crystal growth
