GERMANY: Roller has introduced a range of narrow air coolers for commercial refrigerators, refrigerated cabinets and counters.
In applications where every cubic millimetre of available space matters, Roller’s VW and VM compact air coolers can be placed between the door openings of refrigerated cabinets due to their extremely narrow dimensions. The same applies to the new flat VD ceiling units.
For efficient operation, EC fans are used as standard, saving 80% in energy compared to the previous model.
The dip-coated evaporator block and the powder-coated aluminium housing protect the unit against corrosion. The housing is also available in stainless steel as an option.
In addition to the direct evaporation version with conventional refrigerants, the evaporator series is also available for operation with fluids (brine) and “natural” refrigerants propane or CO2. For the CO2 evaporators, the maximum pressure is 80bar.
EC fans are IP65 and pre-wired on terminal box. The fan panel is removable for easy access to the important components. The drip tray in the VD ceiling-mounted unit can also be rotated through 180°.
The VM offers air routing on both sides and is installed in the centre bar between two cooling compartments, the VW is wall-mounted and the VD is ceiling-mounted, each with one air direction guide.
