ECONET® Air Handling Unit

© Fläkt Woods 5

Fläkt Woods is a world leader in energy recovery systems for air handling units. The most popular systems are:

Run around coils solutions, ECONET or EcotermNo risk of odour and bacteria transferFree to separate the supply air unit from the exhaust air unit

Rotary heat exchangerGood heat recovery efficiencyRisk of odour and bacteria transfer

Plate heat exchangerSimple solutionModerate heat recoverySmall risk of odour and bacteria transfer

High Efficient Energy recovery systems

ECONET® The new heat/cooling recovery system

The traditional wayThe ECONET way

Unique for ‘run around coils’Flexible installation and performance

No leakage between the supply and return air

(no odour and bacteria transfer)

Can also be used for corrossive and polluted air

ECONET® The new heat/cooling recovery system

The traditional wayThe ECONET way

Unique for the ECONET way1 component, 4 functions

lower pressure drops,shorter AHU

Increased heat recovery efficiency 60…75% performance

Able to use cooling recovery

Allways prepared for cooling and cooling recovery

Possibility to utilize process/waste heat

Perfect for district cooling/heating

Fitted for VAV systems

ECONET reduces the investment costs Reduces the size of the chiller Reduced cold water flows, pipe work dimensions

Reduces the size of the boilerReduced hot water flows, pipe work dimensions

Can utilize cheap waste heat

Reduced energy costsBetter energy recoveryPossibility to use waste heat

Smaller foot-print1 component instead of 3 components in the supply air unit

Shorter installation timePre-fabricated pump unit with pre-programmed control box.
