Captive Energy's Heat Recovery Water Heaters are designed to use the waste heat created from cooling loads to satisfy heating loads in a building. Advanced semi-hermetic compact screw compressors are used and operate on the refrigerant vapour compression cycle of R134A. By recovering heat from the condenser water of a conventional water-cooled water chiller, this energy can be used to satisfy a building's potable water heating or space heating loads up to 140°F. Normally this energy is wasted by rejecting it to ambient air in a rooftop cooling tower. Instead, this energy is captured, greatly reducing the fossil fuel consumption of the boiler. In addition the load on the cooling tower is reduced and the condenser water entering on the conventional water chiller is slightly reduced allowing it to meet the cooling demand more efficiently. Depending on the size and timing of the heating and cooling loads it is possible to completely eliminate fossil fuels used for heating. Captive Energy Heat Recovery units are suitable for new installations and as additions to buildings with existing water-cooled water chillers.
For parts and service, we’ve partnered with Control Temp Inc., one of the industry’s most respected HVAC contractors.
Since 1984, Chilliwack's IMW Industries has been a manufacturer of compressed natural gas (CNG) systems used globally to fuel vehicles as well as supply natural gas for industrial users. IMW systems offset more than one million tonnes of GHG annually, and ongoing production will increase offsets by another 400,000 tonnes each year. In Canada, IMW equipment is used in transit bus fleets in Vancouver, BC and Hamilton, ON as well as many fleet and public CNG stations.
