Product Development...

The Company is continually updating its products to comply with changing energy saving technologies, so the introduction of the PVHRU Range of low profile heat reclaim air handling units is based on changes in Fan technology, with the introduction of EC backward curved direct driven plug fans, with 0<10V speed control. Multi fan wall arrangements have been adopted to give higher performance with lower energy consumption. Our team of research professionals are committed to developing products with sustainable energy solutions to meet today’s demands for reducing ventilation energy consumption.


The Packaged Void Heat Reclaim Unit range has been developed to meet the specific fan power requirements of Building Regulations, BS EN 1886 Class B Construction Standards and Ecodirective ErP 2018.

Acoustic Performance...

Extensive acoustic testing of casework construction has been carried out at both the companies testing facilities, and Salford University Acoustic Testing Laboratory. Acoustic tests were carried out on eleven double skin composite panel/frame systems, eight different triple and quadruple skin composite panel/frame systems, to BS. EN ISO10140-2 (2010) which have all been certified as UKAS accredited.
