The ALH series product is the "heat exchanger air processor". The venting of air conditioner and the new air coming into the room should first enter into this equipment.The venting air and new air do the heat exchanger. Use the energy of venting to pre-treat the new air. In summer and winter, the new air can get the cooling and drying or warming and wetting processing so as to do the energy cycling to ensure the circulation of fresh air in the room and effectively recycle the energy.The core part of ALH heat exchanger air processor uses the wing board structure. It can make the cross convection. The special treated film separates the air coming in and the air venting out, making sure the efficient exchanging of the heat and the fresh air coming into the room. Characteristics: 1) The film of the filter is very small, you almost cannot see the fiber constitution of the air hole that reduces the circulating ratio of water- solubility gas, such as ammonia and hydrogen. 2) The crossing airflow board is made of a kind of environment protection board. With the high hydrosphere particularity, it helps the exchange of the vapor that improves the exchanging efficiency of the heat and reaches the conversion of low efficient gas and high efficient heat.Type: ALH-500LX2 Power: 380V/50HZ Electric: 21.5A Rated wind : 5000(1900-7300)m3/h Output pressure: 380Pa Rated temperature : 77% Rated : 5700W Rated power: In air : 2.2(2.2-5.5)KW Out air : 2.2(2.2-5.5)KW Shopping efficiency: cold room: 60% warm room: 66% Noise(Distance=1m): 57.5dB(A) Noise(Pitch=45Distance=1.5m): 79dB(A) Size(whole): 2000 * 1200 * 1960mm Size(in wind): 1100 * 420mm Size(out wind): 640 * 420mm Repaire room : 600mm
