Vent-Axia HR500 Through-the-Wall Unit

All prices are inclusive of VAT



Vent-Axia HR500 Heat Recovery Unit (formerly the Indux 1) is an ideal solution for controlling moisture, mould, and odours in the pool environment whilst recovering up to 70% of the heat from the stale pool air. This self-contained, through the wall unit is the perfect solution for commercial pool halls where a high performance system is required.

The HR500 is an 'intelligent', high performance, and energy efficient system that simultaneously extracts air from inside and supplies fresh air from outside. Both air streams are passed through a specially designed polymeric plastic heat exchanger which extracts heat from the stale air from the pool hall, and pre-warms the fresh air supply. This heat exchanger retrieves heat that would otherwise be lost, whilst consuming no power at all itself.

Speed is fully controllable and there is also the facility to reverse the supply air fan and provide 'double extraction' for warmer periods where heat loss is desirable. The unit should be ducted to the atmosphere using an integral wall liner, should fit wall thicknesses between 450mm and 670mm, and should have washable reticulated foam filters provided in the supply and extract airflows.

Two models are available:

  • HR500 - Standard model with fitted shutters. Weighs 16kg
  • HR500X - Has all the features of the HR500 with the addition of integral shutters. Weighs 19kg
