Herefordshire Council needed to replace the existing fresh air ventilation unit at Halo Leisure Pool. The unit was old, with several attempts made to improve the pool hall humidity and the unit’s energy efficiency over the years, however it had never worked well.

Recotherm were tasked with creating a bespoke, energy efficient replacement unit. Our engineers worked on various different configurations to utilise heat recovery whilst still maintaining the existing inlet and outlet positions. Avoiding the existing unit’s method of a run-around coil system meant we were able to design and build a bespoke unit that incorporated recirculation, allowing humidity control.

The existing 20 year old unit was 8m tall, supported by a welded steel frame; utilising scaffolding and reciprocating saws we were able to remove the unit ready for the new installation.

A steel table was constructed to take the weight of our new unit, which had been delivered on-site in flat pack form. The entire project took 4 weeks, resulting in an energy efficient, state of the art, swimming pool air handling unit incorporating controlled fresh air and heat recovery via a plate heat exchanger with EC speed-controlled fans.  

The council will realise considerable savings on running costs, and importantly much improved conditions in the pool hall with the humidity now under control.
