| 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 |
Common questions
Can a built-in Sub-Zero be repaired without removing the joinery in Witkoppen?
In most cases yes. The units are designed to be serviced from the front through the grille and toe panel; full de-racking is only needed for sealed system work.
Why is my cube ice machine making hollow or small cubes?
Hollow or undersized cubes almost always mean the plate is not being wetted evenly: a scaled evaporator, a weak water pump, or blocked distribution holes. We measure pump flow, descale the plate and re-time the freeze cycle so cubes come out at full weight against the data plate.
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.
