Heat Recovery Systems
There is a current demand in line with government regulations for all new buildings to be highly energy efficient. This includes commercial and industrial buildings. This can be achieved through an energy saving ventilation system. At Neatafan we provide heat recovery systems that utilise warm air that is extracted from the building and would otherwise be wasted. The exhaust or waste stream is recovered and used to heat the building. Rather than mixing the waste air with the fresh incoming air, they pass over one another in a grid formation allowing the transfer of heat from the waste air to the fresh incoming air. Essentially the fresh air is warmed by the waste product with minimal use of energy which maximises efficiency and results in reduced energy bills. The exception being when the exhaust air is polluted, corrosive or greasy, as this would compromise the heat exchanger, and so doesn’t suit a dirty environment.
We have designed heat-recovery systems that are super energy efficient; recovering heat from the exhaust air stream and speed controlled fans that use less energy and last up to 3 times longer than conventional AC fans. Our products are easy to install, require little or no maintenance, utilise less energy and have a longer lifespan. We have been manufacturing air handling units with heat exchangers since 1984, continually improving our products to maximise efficiency. The recovery efficiencies achieved in our heat recovery systems in practice are between 45% and 75% when compared to a system that doesn’t utilise such technology. This helps the user to save energy and money whilst maintaining good energy saving practices aligned with current government regulations. Our systems can also be used to cool the building during a summer evening if the outside ambient temperature falls sufficiently. A Neatafan control system combined with a by-pass damper further optimises these opportunities.
Our latest heat recovery units now benefit from EC/DC motors with built in speed control. Not only can the air volume be reduced for low occupancy but it can also be reduced in very low ambient temperatures if the ventilation demand can be met. The power requirements of these motors falls away more rapid then the equivalent inverter controlled AC motors. The increased energy efficiency of these systems together with high-efficiency filters ensures longevity of our systems and low maintenance which also helps to save money in the long run.
It is with this in mind, combined with our reputation for quality combined with decades of experience, that positions us at the forefront of the commercial ventilation market.
