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.

Providing up to 78% heat recovery, the Tempra is the only unit of its type which can be retrofitted through a 100mm diameter hole in the wall. This enables standard bathroom, kitchen, toilet or utility room fans to be easily changed for a Tempra without the need to make the hole any larger, saving significantly on installation time and cost.

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 significant energy savings and will help reduce a home’s carbon footprint.

Tempra is discrete and quiet in operation. It can be set to run continuously at 6 l/s or 9 l/s, boosting up to 13 l/s if required. For intermittent extract applications, the unit can be set to operate at 15 l/s. It also incorporates a manual summer bypass to ensure that when it is warm outside, it operates on extract only. This eliminates the risk of a dwelling overheating in hot summer conditions.

Complying with Building Regulations 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.

Tempra is part of the Vent-Axia Lo-Carbon™ collection of energy saving ventilation solutions. The aim of the Lo-Carbon™ initiative is to offer the latest low carbon ventilation technology to reduce building energy consumption and carbon emissions.
