Inverter Upright Chiller
The Inverter Upright Chiller is a commercial storage chiller available in 2, 4 or 6 door models to suit different kitchen sizes. All run an inverter compressor with R290 refrigerant for lower energy use than a standard chiller.
Berjaya Inverter Upright Chiller is built for kitchens that need steady cold storage without a heavy power bill, from busy cafés up to hotel back-of-house. The 2, 4 and 6 door configurations, so you can match storage capacity to the size of your operation rather than overbuying or running short on shelf space. All three run an inverter compressor with R290 refrigerant, which is what sets this range apart on running cost against a standard fixed-speed chiller.

Frequently asked questions
Q1. What is R290 refrigerant and why does it matter?
R290 is a natural hydrocarbon refrigerant with a very low global warming potential compared with the older synthetic gases. The 2DUC-IV-Z, 4DUC-IV-Z and 6DUC-IV-Z all run on R290, which keeps the range ahead of refrigerant phase-down rules in Malaysia.
Q2. What does the inverter compressor actually change day to day?
It varies its speed with the load instead of switching on and off at full power. On the Inverter Upright Chiller that means a lower starting current, a quieter kitchen, steadier holding temperatures and a lower electricity bill than a fixed-speed equivalent.
Q3. Why does the insulation thickness matter?
Thicker, high-density foam slows heat transfer from outside to inside, so the unit maintains a stable internal temperature with less strain on the cooling system.
