Indoor compact unit ventilators of DUPLEX-S 1500 to 5600
series are used for comfort ventilation, as well as warm-air
heating and cooling of small office areas, shops, retail
facilities, school buildings, restaurants, small stores, sport
centres, industrial halls and swimming pools.
The units are suitable for all facilities where effective
ventilation or warm air circulation heating/cooling
at minimum operating costs is required; it means high-
efficient heat recovery, low power consumption of fans
and minimum noise level.
The units are available in two basic versions:
– indoor version
– rooftop version
(with double insulation)
The units may optionally be equipped with efficient EC type
fans with constant airflow control option.
The DUPLEX-S unit is designed as a compact appliance.
In single casing it contains: two independently controlled
centrifugal fans with anti-vibration motor support,
• high recovery efficiency of counterflow exchanger – up to
80%
high-efficient
counterflow
air-to-air heat recovery core
• highly compact shape enables space reduction up to 60 %
assembled from thin plastic plates, removable supply
compared to units with modular design
and exhaust air filters of the G4 or F7 class, condensation
• low purchase cost
pans, an optional internal by-pass with a remote-controled
actuator and a mixing damper with an actuator.
• up to 32 installation configurations
The unit casing consists of steel L–profile frame
• choice of non-standard connection ports (round or
and sandwich panels made of aluminum metal sheets filled
rectangular) on request

configuration based on an order.
• high chemical resistence of the hPS exchanger
In the rooftop units inlet and outlet ports are standardly
• optional hygienic design according to the VDI 6022
covered by hoods. We recommend that both shutoff
dampers be installed to prevent drafts.
• optional delivery in disassembled state for inaccessible spaces
