Local context

Working in Seshego Industrial

We service Seshego Industrial and the surrounding blocks of Seshego Industrial, Polokwane, with access off the N1 and R521. Long, hot lowveld summers regularly exceed 36 °C, so high-ambient head pressure control and shaded plant rooms are non-negotiable.

FAQ

Danfoss temperature mapping & validation in Seshego Industrial

How fast can a technician service Danfoss equipment at a data centre & critical cooling site in Seshego Industrial?

Seshego Industrial sits on the N1 and R521, so our Polokwane dispatch reaches most Seshego Industrial sites inside a standard callout window. Emergency temperature mapping & validation runs 24/7 because thermal runaway trips racks within minutes.

Do you stock OEM components for Danfoss systems?

Yes — Danfoss ETS/TES valve bodies, AKS 32R transmitters and EKC 202 controllers. Danfoss (Denmark) equipment on R134a/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 temperature mapping & validation 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 temperature mapping & validation performed against Client setpoint band, typically +2 °C to +8 °C. Thermal runaway trips racks within minutes
