Modular unit with run-around coil heat exchanger for air flows from 0.2 to 11.0 m³/s

Product description
WLB is a modular unit equipped with a run-around coil heat exchanger. The modular design offers great flexibility when it comes to choosing functions. Run-around coil heat exchangers are not normally as effective a method of thermal recovery as other types of heat exchangers. They do, however, offer other advantages that may be of interest in certain types of applications. One advantage is that you can install the supply and exhaust air components in different parts of the building. Piping is then used to transport the energy between the two. This can be of interest when there is too little room for another unit type. Another advantage is that the air streams are completely separated without any risk of odour transfer.
WLB is available as a modular or turnkey unit. Even turnkey units can be easily dismantled into modules after delivery to simplify transport.

WLB can prove favourable in applications where odour transfer must be ruled out and/or where space is insufficient for other types of heat exchangers.
WLB units are available for installation indoors, outdoors or with extenders for a downwards warm-side duct connection, through the rooftop. The latter option includes a foundation frame that is normally delivered 2 weeks before the unit to facilitate installation.
