ECW 10÷100
WATER CASSETTE 3-SPEED OR EC INVERTER RADIAL FAN
The Water Cassettes ECW 10÷100 have been projected to be installed on false ceiling. The intuitive design makes installation and maintenance process easier, while guaranteeing the highest levels of energy efficiency and silence, both in domestic environments or in the services sector including offices, hotels, restaurants, gyms and shops.
When part of a hydronic system equipped with a Liquid Chiller, the Water Cassette generates cool air, while, during the winter, if combined with a thermal system, it provides warm air, making possible to meet home or business heating needs. The series, in addition to having a rich set of accessories to complete the unit, also has an attractive and modern intake grill cover panel, with neutral and well-balanced shapes that integrates perfectly in the surrounding environment as well as adjustable deflectors to distribute the air in the room in an ideal manner.
Units are available both with 3-Speed and EC Inverter fans. The units equipped with EC Inverter motor modulate the air flow, adapting the performances instant to instant to the actual needs of the room to be conditioned, assuring a total comfort with greater energy savings.
