Benson Recoupak cased de-stratification fans are purpose designed to provide a permanent reduction in roof space temperature. The displacement of this pool of warm air from the roof void to working zone level has a positive impact in the reduction of fuel usage which, depending upon building height, can be as much as 15%. Additionally, the air movement recommended has distinctly beneficial effect on operative comfort levels by providing a high level of uniformity of warmth throughout the area where fans are applied.
Specification:
Casing: Manufactured from electro zinc coated steel sheet finished with a durable stove hardened epoxy polyester powder paint. Four eye bolt suspension points are provided. Purpose designed fixing kit available as an option.
Controls: Recoupak fans are supplied ready for automatic operation with installations only requiring mounting and connection of a single phase electrical supply. Each fan is fitted with an integral thermostat which makes on temperature rise.
Air Distribution: The in-built thermostat prevents the premature discharge of cold air, automatically operating the fan on temperature rise gently re-directing the warm air downwards through an adjustable four way louvre.
Testing: Every fan is individually inspected and tested prior to despatch.
Guarantee: Benson Recoupak fans are provided with a twelve-month parts only guarantee.
Design:
Firstly: Select the fan unit to suit the mounting height requirements. Ideally the fan/s should be positioned about one metre under the highest roof point or apex
Secondly: Calculate the building volume in cubic metres, then multiply the volume by two so that the fans displace the building air volume twice each hour.
Thirdly: To determine the number of fans required divide the result of the building volume multiplied by two by the fan displacement (as measured in cubic metres per hour)
