Vent-Axia has launched the new Lo-Carbon Tempra – the first single room heat recovery unit on the market which allows contractors and social housing specifiers the opportunity to quickly and easily replace existing, inefficient fans with a discrete, low energy, continuously running alternative. <br> <br> The unit’s compact heat exchanger is capable of recovering any heat from extracted air and returning it back into the dwelling. This performance, taken together with Tempra’s integral Lo-Carbon DC motor, brings energy savings. <br> <br> Complying with Part F for intermittent extract fans and whole house ventilation systems (depending on its application), Tempra is available in a choice of four models. These include a standard version, an option with light switch control, a T version with an overrun timer and an H version with built-in humidistat.<br> <br>
