The current multi-purpose compact DUPLEX units are popular also due to the wide range of versions available, thus allowing the installation of these units not only in a horizontal position, but also vertical, ceiling-suspended or floor-standing (flat) position.

These options have now been extended by a upright version, which has all 4 outlets headed upwards, and the ductwork is in some cases much more simple and as a result saves installation space.

The new upright version is available not only for DUPLEX units with a cross-flow heat recovery exchanger, but also for units with a counter-flow heat exchanger with high heat recovery efficiency.

Like all other types, the new upright version of the unit may be equipped with a built-in control system, either of a power type, a digital type or a special type for commercial kitchens.

Furthermore, the units may be fitted with a heater, a water / direct cooler, a by-pass damper and a circulation damper, shut-off dampers on both the supply and the exhaust side.

As standard, these units are supplied with mounting legs and condensate outlets.

The upright units are also fully supported by the special selection software from version 5.20 upwards, which makes the design of the unit and all accessories significantly easier and faster.

New upright version 50 and 51 of DUPLEX and DUPLEX-S will be available from January 2009.
