Product features
Efficient, uniform cold air distribution in the cabinet
Three installation / airflow routing variants for each type of cooling equipment (VM=middle; VW=wall; VD=ceiling)
Wide range of applications with a temperature range down to -20 °C
Robust aluminium housing, scratchproof powder-coated finish
Reliable and robust refrigeration cabinet air coolers
In gastronomy, the catering industry, the requirements for air coolers are as varied as the food and beverage offered. In large kitchens, restaurants, bars and cake shops, drinks, ice cream, marinades, meals and their ingredients must be hygienically chilled. Because the doors are frequently opened, the cooling equipment is subject to significant temperature fluctuations. This means that high-performance cooling is required. Furniture air cooler from Roller guarantee reliable, efficient cooling of food, even under extremely difficult conditions.
Installation depth decisive for commercial cabinet coolers
In commercial refrigerators, refrigerated cabinets and counters, every mm³ available space matters.
The compact air coolers VW and VM can be placed perfectly between the door openings of refrigerated cabinets due to their extremely narrow dimensions. The same applies to the flat VD ceiling units.
The EC fans used as standard make operation particularly efficient.
The standard dip coating of the evaporator block is ideal as corrosion protection for mixed storage of open foods such as salad, marinades,...
All new features at a glance
New, high-performance EC fan
with approx. 80% energy savings compared to the previous model. The fan is installed flat to the housing.
Flexible installation of the drip pan
The drip tray can be turned 180° (VD) and offers more installation flexibility in the refrigerated cabinet
Terminal box for individual electrical connection
Fans pre-wired on terminal box with increased IP protection (fan with IP65)
Simple air cooler replacement
Fixing points and external dimensions for easy 1:1 replacement unchanged

Medical technology - VW - Stiel
Over the years, the company Stiel Kälte und Klima based in Tübingen has developed into a specialist for medical and laboratory cooling. When building its systems, it relies on special heat exchangers from Roller. In this case, for cooling medicines, the company opted for Roller's VW 3 fan cooler for cooling equipment and cold rooms with water cooling.
