Condair HP - new in-duct high pressure humidifier
The Condair HP is a new in-duct high pressure spray humidifier that can deliver up to 1,300kg/hr of humidification and a potential 884kW of evaporative cooling from just 2.2kW/h of electricity.
A high pressure pump provides water at around 70bar to a series of spray nozzles located on a stainless steel manifold inside an air handling unit. The nozzles release the water as a very fine mist that is quickly absorbed into the airstream. Any water that isn’t fully evaporated is removed from the air by a droplet separator guaranteeing droplet-free humidification.
As the spray nozzles are located uniformly across the duct, the humidity is spread evenly for optimum humidification with minimal waste water. Seven-stage operation on the standard model offers humidity control of ±4%RH while a close control option has 15-stage control and provides ±2%RH.
The Condair HP can deliver humidification in up to four AHUs from a single pump station with local control on each zone. This makes the humidifier an economic option for AHUs that incorporate humidification of incoming fresh air as well as an evaporative cooling/heat recovery combination on the exhaust air.
The Condair HP pump station features a water-lubricated, oil-free stainless steel pump with an 8,000 hour guarantee, driven by a low energy Grundfos motor. The pump station also features optional integrated reverse osmosis water treatment plant making it ideal for areas without an existing RO water supply. The humidifier operates on RO water so that minerals are not introduced into the AHU.
The humidifier's hygiene management system incorporates regular flush cycles to ensure water cannot remain in the pipelines to stagnate. Optional ultra violet sterlisation will kill microorganisms in the water supply. All sections of the water system are manufactured in strict accordance with the HACCP/ISO 22000 Hygiene Management System.
