Inverter Upright Freezer
A commercial upright freezer range built for -18 to -12 degree frozen storage, available in 2, 4 and 6 door sizes with an inverter compressor for lower running costs. Stainless steel construction and R290 refrigerant come standard across every size.
Berjaya Inverter Upright Freezer range gives Malaysian kitchens frozen storage that holds -18 to -12 degrees Celsius while cutting the electricity bill against a standard compressor. The range runs from the 2-door through the 4-door to the 6-door, with gross volume rising as door count increases so you can match capacity to storage space rather than overbuying. All three use an inverter compressor with R290 refrigerant, a solid self-closing door and stainless steel construction, with full specifications for each model set out in the table below.

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 older synthetic gases. The Inverter Upright Freezer range uses R290 throughout, keeping the equipment 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. That means a lower starting current, a quieter kitchen, steadier holding temperatures and lower running costs 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.
Q4. What defrost system do these freezers use?
The Inverter Upright Freezer range uses an automatic electric heater defrost system, which keeps energy consumption down and the defrost cycle as short as possible with no manual defrosting needed.
