Local context
Working in Blackheath
We service Blackheath Industrial and the surrounding blocks of Blackheath, Cape Town, with access off the N1 and R300. Mediterranean summers with strong south-easters carry dust and salt onto condenser coils, and winter rain drives condensation risk at dock openings.

FAQ
Danfoss temperature mapping & validation in Blackheath
How fast can a technician service Danfoss equipment at a potato & onion storage site in Blackheath?
Blackheath sits on the N1 and R300, so our Cape Town dispatch reaches most Blackheath Industrial sites inside a standard callout window. Emergency temperature mapping & validation runs 24/7 because condensation on bins causes rot spread through the stack.
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 R404A/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 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 GLOBALG.A.P. documentation your auditors expect.
What operating envelope do you commission this equipment to?
Potato & Onion Storage run at +4 °C to +10 °C at 85–95% RH, with temperature mapping & validation performed against Client setpoint band, typically +2 °C to +8 °C. Condensation on bins causes rot spread through the stack
