Specialist heat-pump and heat-recovery-system manufacturer Heatstar has shown the large commercial indoor pool Taurus units for leisure centres and municipal applications, which will now feature ‘Low Carbon Ventilation’ EC fan technology.

This technology, which Heatstar says has proved so successful in reducing project energy consumption in their Phoenix and Andromeda models, is now being extended throughout the larger product range.

The special fan features the latest Electronically Commutated (EC) technology based around a DC motor coupled to an integrated frequency inverter which, coupled to a high efficiency ‘backward’ curved fan impeller, enables the same quantity of air flow to be produced, but at much reduced motor power consumption. The adjustable fan will also automatically operate in a slow speed ‘eco-mode’, during periods when there is low demand for either air heating or dehumidification during unoccupied periods.

The Taurus range (see picture) offers refrigeration dehumidification rates between 16.2 and 138.4 kg/hr and air flows from 1.1 to 15.6m³/sec, and with the capacity to deal with the largest leisure centre or Olympic-sized pool complex. Taurus units are available in six different capacity sizes and three different versions: the Taurus HP, a heat pump dehumidification type system; Taurus HPXF – a heat pump dehumidification and X Flow air-to-air plate recuperator; and Taurus XF – with just X flow air-to-air plate recuperator.

Heatstar also says its 2012 model Aquarius heat pumps will be offered with a 20-year titanium heat exchanger and aluminium chassis guarantee. On-site aftersales support is provided by Heatstar’s own technicians.
