SystemX - Wholehouse heat recovery ducting kits
Ducting system for mechanical ventilation with heat recovery.
Key features
Type: Ducting system Application: Mechanical ventilation with heat recovery
The range
Xpelair Xcell wholehouse heat recovery units feature over 90% heat transfer efficiencies and low running cost ‘LongLife’ dc motors. To ensure that as much of this valuable heat energy gain is delivered back to the living areas, Xpelair has developed two SystemX kits which contain all the main ductwork components needed for a standard three or four bedroom two level new home. Kit 3 is suitable for a typical 3 bedroom home and Kit 4 is suitable for a typical 4 bedroom home.Not only does this simplify the specification but the kits offer substantial savings over the cost of the individual components.
The systems are based on a low pressure drop design, aiming to keep the air paths as large as possible and providing the main resistance at the inlets and outlets.
The kits consist of Profile 150 and Xflex TFD components for ducting in uninsulated cold areas such as the loft, Profile 60 components for vertical risers in stud walls and other vertical voids, and splitters and RegulAir intake and outlet terminations for wet rooms and living areas.
Site conditions will inevitably mean that a few components more or less will be required to complete the project. Choose these from the accessory list.
SystemX components are delivered in a series of easy to handle master cartons with first fix items separate from the second fit fixing and grilles.
Because of the grease content, it is recommended that kitchen canopies are not connected to the system. Instead, use a separate extract point at ceiling level.
