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.We work across every major brand installed in Witkoppen, and diagnostics start from the plated design data rather than a guess.Every visit starts with a full diagnostic and a written quote before any part is fitted.Mixed access; some sections open, some boomed. Ice Machine Repairs bookings in Witkoppen are logged against Block 12 so we can allow for power availability on site.

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
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.
Why is my ice cloudy or melting too fast?
Cloudy, soft ice means the freeze cycle is being cut short or the water is carrying too many dissolved solids. We test hardness and TDS on site, fit the right filtration, descale the plate and re-time the cycle so cubes freeze clear and hard.
Is scale really a problem for ice machines here?
Yes, it is the single biggest cause of lost output on this water supply. Scale insulates the evaporator, so the machine runs longer for less ice and eventually pits the plate. Regular descaling is far cheaper than an evaporator replacement.
