USE

KWT plate heat exchanger with X-shaped air passage designed for exhaust air heat recovery in conditioning and ventilating systems. The heat exchangers are connected directly to the rectangular ducts both with parallel and perpendicular or diagonal ducting at 45°. Various connection modification are possible due to bend fittings which shall be ordered in the required quantity. The transported air shall not contain solid, fibrous, aggressive and explosive impurities.

DESIGN

The heat exchanger casing is made of galvanized steel. The surface of the heat exchanger consists of thin aluminium plates for efficient heat exchange. Some condensate quantity which can be generated at exhaust surface can be removed at the bottom removable panel. KWT heat exchangers equipment list includes connecting pipe on the bottom panel for condensate removing.

ACCESSORY  

BH BEND

Designed for easy mounting of the heat exchanger in any modifications of the air duct.

SB C4 SUMMER BLOCK

For the summer period the heat exchanger can be replaced with the summer block SB C4 which performs no heat recovery but reduces pressure loss by 10 %. It is applied in systems without by-pass at the inlet and in systems with no cooling.

Additional characteristics
Additional characteristics

Heat recovery efficiency and air resistance in the air duct are the basic factors that determine the heat exchanger performance.

 

The thermal efficiency is calculated as following:
ŋ = (ts - ti) / (te - ti)
ts – supply air temperature after heat recuperation ti – intake air temperature before heat recuperation te – extract air temperature before heat recuperation
