Local context
Working in City Deep
We service City Deep Fresh Produce Market, City Deep Container Terminal and the surrounding blocks of City Deep, Johannesburg, with access off the M2 and N17 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.
Simultaneous cooling, dehumidification and reheat Humidity excursions cause mould loss in drying rooms

FAQ
Danfoss variable speed drive installation in City Deep
How fast can a technician service Danfoss equipment at a cannabis cultivation & drying site in City Deep?
City Deep sits on the M2 and N17 and N3, so our Johannesburg dispatch reaches most City Deep Fresh Produce Market sites inside a standard callout window. Emergency variable speed drive installation runs 24/7 because humidity excursions cause mould loss in drying rooms.
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/R449A 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 variable speed drive installation 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 SAHPRA GACP documentation your auditors expect.
What operating envelope do you commission this equipment to?
Cannabis Cultivation & Drying run at +15 °C to +22 °C at 50–60% RH, with variable speed drive installation performed against Turndown to 30% of rated duty. Humidity excursions cause mould loss in drying rooms
