Calorex brings new lease of life to indoor swimming pool

Conditions in this swimming pool in Staffordshire have been transformed following the replacement of the full-fresh-air ventilation system with a Calorex HRD air-handling unit.
Conditions in the swimming pool of South Moorlands Leisure Centre in Staffordshire have been transformed following the installation of a heat-recovery air-handling unit from Calorex Heat Pumps. Before the overhaul of the existing ventilation system, the pool hall suffered condensation and damp problems, resulting in rotting windows and doors as well as unpleasant conditions for swimmers and staff. The HRD30 air-handling unit was installed by George Birchall Ltd with minimal downtime. It typically removes 300 litres of water in a 24 h cycle and plays a vital role in maintaining temperatures and conditions for the indoor environment. It typically offers 300% heat recovery to pool water and/or air in the pool hall, compared to 50 to 60% from recuperator-type air-handling units. John Thomas, independent consultant for the project, explains, ‘The Calorex unit was an obvious choice as we were looking for a system that would not only overcome the ongoing problems caused by condensation but also operate with greater efficiency than the existing 30-year-old system, which was coming to the end of its life cycle.’ The installation was part of a scheduled shutdown for repairs. HRD units can reduce energy consumption by up to 60% and associated carbon-dioxide emissions by up to 55% compared to a full-fresh-air ventilation system similar to that replaced.
