Mitsubishi Electric utilizes Lossnay heat recover paper cores within its MVHR and packaged AH systems to provide excellent ventilation alongside heating and /or cooling system, ensuring a healthy and comfortable environment, whatever the building. Developed and refined over the past 35 years, our Lossnay heat exchanger cores have perfected mechanical ventilation with the recovery of heat energy that would have otherwise been wasted. This helps to reduce overall energy costs by extracting stale air and then recovering the heating or cooling energy to either warm or cool incoming fresh air.
