The CTR is an electrically operated 3-way valvedesigned specifically for operation in CO2 systemswith heat reclaim. CTR is designed to allow fullproportional control of the surplus heat fromcompressor pack into the heat exchanger oftrans critical heat reclaim solutions.The proportional control of the CTR ensures thatthe exact amount of heat required is available atany time, and the possibility to operate smoothlyin changeover sitiuations allowing for stablecontrol.The typical application for the CTR is a Pack/rack system in food retail application workingwith trans critical CO2. Heat reclaim is the currentmost attractive energy advantage of trans criticalCO2. Even as trans critical CO2 systems are onpar or outperform traditional HFC installationson energy performance, this also ensures thepossibility to supply high quality heat to beexploited. Heat reclaim is seeing an increaseddeployment and becoming a norm in mosttrans critical CO2 retail installations today
