Fresh Air Exchanger
Bidirectional ventilation: Through bidirectional ventilation between indoor and outdoor, the intake and exhaust air are exchanged in equal amounts, controlling the temperature changes and ensuring a continuous supply of fresh air.
Filtration treatment: Equipped with different filtration materials, fresh air filtration treatment can effectively purify the air. Installing different filters can effectively prevent pollutants such as dust and harmful gases from entering the room.
Safe and reliable: The low-noise fan and internal noise reduction treatment prevent interference with the site. The entire machine has no moving parts except for the fan and requires almost no maintenance, ensuring long-term stable and reliable operation.
Low cost and high efficiency: It can replace fresh air treatment equipment, eliminating the need for a separate operation room, which can reduce equipment investment and building area. By utilizing heat recovery technology, it saves energy and reduces consumption, significantly lowering operating costs.
Fresh air exchanger series
Energy and environment
Air-conditioner nowadays has become a protector for people from heat and chill. However, it has an innate defect, which is a problem many users have been facing, interior air contamination. This is the main cause of out-bursting and spreading of air-conditioning sickness, respiratory disease, SARS virus, and Legionnaires’ disease. It is proved that when the air-conditioning is on, number of bacterium in the air is 3-4 times of that when the air-conditioning is off. Indoor air contamination has become the biggest environmental cause of human health problems. An air-conditioning room is lack in Oxygen and fresh air, which has been an unsolved problem. Cool and heat energy in the exhaust air not been effectively recycled has become a shocking phenomenon of energy wasting. As energy crisis be a worldwide concern, China has taken energy saving as a long-term strategy of sustainable development.
New healthy concept of fresh air
Features of thermal insulation and high air tightness of air-conditioning room determines that method of windows to exchange fresh air is bound to be replaced by heat exchanger with a hundred percent fresh air ventilation. GRAD fresh air exchanger provides an overall experience of fresh air in the air-conditioning room, as if it were the breathing organ of the muted house. It keeps out various pollutants, such as smoke, dust, stench and other uncomfortable air, through regular air exhausting and supplying. Pure, comfortable air with abundant Oxygen is drafted into the room. GRAD fresh air exchanger has become the “lung” of nowadays residential buildings virtually. It is a new healthy and green product of fresh air exchanger
New high-efficient and energy-saving concept of heat and humidity recovery
GRAD fresh air exchanger breaks the technical bottleneck of low efficiency in heat recovering of traditional machines with applications of High-tech nano membrane, convection technology, antistatic technology, maintenance-free, and muffling technology. Our products’ recovering ability of energy in exhaust air has been improved a lot, with 75% of heat and humidity recovered so that our users can enjoy fresh air in a low cost. Not only is the lump sum investment in the equipment reduced, less space does the main engine occupy, but also the operation cost of integral system is reduced.
New companion relationship with air-conditioning
Since at least 90% of one’s life is spent indoors, the air quality of an air-conditioned room has great impact on human health. Our health is decided by four indispensable elements: air, water, nutrition and appropriate exercise. Our fresh air exchanger not only solves the problem of lack in fresh air, but also recycles the energy in exhaust air, which meets the idea of health and energy efficiency. The fresh air exchanger has become a necessary companion product to air-conditioning.
