Ice machine re-gassing with proper leak detection first: we find and fix the leak, then weigh in a fresh charge rather than topping up. In Witkoppen this is luxury gated estates work on sealed refrigeration system systems, attended within about 65 minutes of dispatch.On Defy equipment specifically — domestic double-door, side-by-side and chest freezers — the faults we see most in Witkoppen are inverter compressor board faults and water dispenser valve leaks.Every visit starts with a full diagnostic and a written quote before any part is fitted.Mixed access; some sections open, some boomed.

Refrigerant data
| Gas | Classification | Suction pressure | Discharge pressure | Typical use |
|---|---|---|---|---|
| R134a | HFC (A1) | 80-140 kPa at -5 degrees C evaporating | 900-1 200 kPa at 45 degrees C ambient | Wine cellars, display cabinets, medium-temperature commercial refrigeration and some heat pumps. |
| R404A | HFC blend (near-azeotropic) | 40-60 kPa (approx. 2-4 bar) | 1500-1900 kPa | Older commercial ice machines, cube makers, ice bins and blast chillers |
| R448A | HFO/HFC blend (low GWP) | 50-75 kPa | 1600-2000 kPa | Modern commercial ice machines, cube and flake units, coldroom retrofits |
| R290 (propane) | Natural hydrocarbon (A3 flammable) | 30-50 kPa | 1000-1400 kPa | Undercounter and self-contained ice makers, nugget machines, back-bar units |
Common questions
Why is ice building up at the back of my Defy fridge in Witkoppen?
That is almost always a defrost circuit failure: the heater, bimetal or defrost sensor. The ice blocks the evaporator, airflow drops and the fridge compartment warms up while the compressor runs constantly.
Can you just top up the gas in my ice machine?
No: a machine low on refrigerant has a leak, and topping up hides it. We leak-trace electronically and under nitrogen, repair the joint, fit a new drier, pull a deep vacuum and weigh in the exact plated charge.
Do you charge a callout fee?
A standard callout and diagnostic fee applies and is quoted upfront. It is credited against the repair when you accept the quote.
