On 1. 7. 2011 new version 5.90. of the selection software for DUPLEX units was released.

Please download the updated version of the software on the dedicated site.

Detailed listing of new functions:

1) added DUPLEX-S 1600 and DUPLEX-S 2600, new compact multi-purpose units including new controls of the RD series

• rather new line of universal “stock” units
• more information you will find on catalogue pages

2) for small unit ventilators (EC, ECV) added function of ventilating air calculations based on room selection

• similar like to dual-zone units, you can now calculate ventilation rate according to the rooms or people

3) unification of air inlet/outlet nomenclature with the EN 13779



4) catalog sheet update

5)  many internal changes for faster program performance

6) And a lot of other minor modifications and error corrections

The product range of small unit ventilators was extended with the DUPLEX 540 ECV with max. airflow of 550 m³/h. You can find detailed information in the updated catalog sheet.

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.

Further information you can find in DUPLEX 2000 to 8000 units and DUPLEX-S 1500 to 5600 units.

We would like to inform you about the widening of the range of electric air heaters. The current range of EPO electric air heaters has been completely replaced by a new EPO-V range.

Main changes:

• rectangular types added to the range
• types with a higher capacity up to 54.0 kW added to the range
• unification of types – as standard, all heaters now contain non-spurious switching elements and can be used for all types of control systems – digital, power and kitchen systems – and also for EC and ECV units
• lower minimum air flow demand (as a result of lower accumulation inside the heater)
• unlike in previous types, the housing of EPO-V's can be fully insulated, with the exception of the lid
• two heaters can be installed in series one after another to increase output
• the maximum power output in high-output heaters can be easily reduced – see the catalogue sheet
• All EPO-V types will be permanently available in stock

New EPO-V heaters 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.

EPO-V heaters will be available from January 2009, for a limited period of time simultaneously with the existing EPO range.
