Water evaporates from the surfaceat hundreds of litres every hour.Evaporated water needs to be removedor it will turn to condensation that willimmediately start to cause problems tothe building environment and fabric.The HRD contains all necessary sensingand control equipment within its cabinet.It will remove all of this moisture from theair, collect its latent energy and reuse it toassist water and air heating.Heat recovery from the unit is usuallysufficient to satisfy all of the operationalpool water heat requirements.By this means a heat cycle is created whichkeeps heating costs to a minimum.This also significantly reduces the carbonfootprint of the leisure centre.Clearly evident, the Calorex HRD30 guarantees minimal CO2 emissions(per annum) compared to the other processes tested.8-pageFinal.indd 4 28/1/08 15:57:23
