Description
Description
FEATURES
Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings.Heat and humidity recovery minimizes ventilation heat losses during cold season and reduce air conditioner load during hot season.Controllable air exchange for creating the best suitable indoor microclimate.Compatible with round Ø125 mm air ducts.
FANS DESIGN
High-efficient external rotor EC motors and centrifugal impellers with backward curved blades are used for air supply and exhaust.EC motors have the best power consumption to air flow ratio and meet the latest demands concerning energy saving and high-efficient ventilation.EC motors are featured with high performance, low noise level and totally controllable speed range.Dynamically balanced impellers. The casing is made of expanded polypropylene (EPP) 15-26 mm thickness with high heat- and sound-insulating properties.
AIR FILTRATION
The supply and extract air streams are stripped of impurities on the panel G4 air filters. Optionally a F8 replaceable filter may be applied.

HEAT RECOVERY  
KOMFORT EC S5B270 have a counter-flow polystyrene heat exchanger. In the cold season the extract air heat energy is absorbed by the cold intake air and the ventilation heat losses are minimized. The condensate produced by heat recovery is collected in a drain pan and drained to the sewage system. In the warm season the heat of the outside air is absorbed by the exhaust air. This way the supply air is pre-cooled and operation load for air conditioners is reduced.
KOMFORT EC S5B270-E have a counter-flow enthalpy membrane heat exchanger. In the cold season the heat and moisture contained in the extract air are transferred to the intake air flow through the enthalpy membrane. This way the ventilation heat losses are minimized. In the warm season the heat and moisture of the outside air are absorbed by the exhaust air through the enthalpy membrane. This way the supply air is pre-cooled and dehumidified and operation load for air conditioners is reduced.
BYPASS  
The KOMFORT EC S5B270(-E) models are equipped with a bypass which can be opened if there is a need to cool down the ventilated area with cool intake air.
MOUNTING  
The ventilation units are designed for wall mounting.Due to universal casing design both left and right mounting is possible.The service panel located on the left and on the right from the unit as seen from the supply air direction.
CONTROL AND AUTOMATION
KOMFORT EC S5B270(-E) S14 has an integrated control panel with sensor buttons and LED indication.

FREEZE PROTECTION

The freeze protection is based on shutdown of the supply fan. In case of a freezing danger communicated by the temperature sensor the supply fan turns off for a period that enables warming up of the heat exchanger with warm extract air. After a freezing danger is no longer imminent the ventilation unit reverts to the standard operation mode.
