The compact DUPLEX 2000
–
8000 heat recovery
ventilators 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
centers, 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:
(with double insulation)
The DUPLEX unit is designed as compact appliance. In single
casing it contains: two independently driven centrifugal fans
with anti-vibration motor support, high-efficient cross-flow
air-to-air heat recovery core assembled from thin plastic
plates, removable supply and exhaust air filters
of the G4 or F7 class, condensation pans, an optional
internal by-pass with a remote-controled actuator
and an internal mixing damper.
The unit casing consists of steel L-profile frame and sandwich
panels made of aluminum metal sheets filled with
polyurethane insulation (thermal resistance R = 1,05 m KW ,
or 2,1 m KW ). The sandwich panels are fixed to the frame.
A front access door enables comfortable access to all
components and filters. Standard surface finish.
Inlet and outlet ports are round or rectangular with different
location configuration based on an order.
Indoor ports of the rooftop unit are from bottom and outdoor
ports are fitted with hoods. They can optionally be fitted with
sound attenuators. It is recommended that both shutoff air
dampers be installed to prevent draft.
The units can be equipped with high-efficient EC fans with
optional constant volume flow control.
