FAQ
Danfoss variable speed drive installation in Wilsonia
How fast can a technician service Danfoss equipment at a cannabis cultivation & drying site in Wilsonia?
Wilsonia sits on the N2 and N6, so our East London dispatch reaches most Wilsonia Industrial 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
