The material for panels is PU, PE or glass cotton. polyester foam as a whole. The cabinet has advantages of anti-corrosion, beautiful, durable and small air leakage rate.Air filterAHU Filters is specifically designed for Air Handling Unit, which are widely used for filtering the air and thus, ensure clean air for healthy breathing. Our assortment of AHU Filters is used for proper ventilation &suctions of AHU's installed at hospitals, hotels, malls and other such establishments.The specially designed plate filter can be freely extracted from the left, right, upper and lower sides of the unit, so it is especially suitable for the maintenance and cleaning of compact space.The filter material can be made of cotton concave and convex net or non-woven fabric.Optional Filter Class:G4+F7+H10+H13:FanThe fan is centrifugal type fan with low noise and high efficiency external rotor. The fan is balance corrected precisely to ensure its stable operation, low noise, small vibration and superior performance.The definition of air handling unit from ANSI/AHRI Standard 430-2009 states that it is "A factory-made encased assembly consisting of afan or fans and other necessary equipment to perform one or more of the functions of circulating, cleaning, heating, cooling, humidifying, dehumidifying and mixing of air...."The AHU is used to control the following parameters of the space.TemperatureHumidityAir MovementAir CleanlinessAn Air Handling Unit (AHU) is used to re-condition and circulate air as part of aheating, ventilating and air-conditioning system.The basic function of the AHU is take in outside air, re-condition it and supply it as fresh air to abuilding. All exhaust air is removed, which creates an acceptable indoor air quality. Depending on the required temperature of the re-conditioned air, the fresh air is either heated by arecovery unit or heating coil, or cooled by acooling coil.In buildings, where the hygienic requirements for air quality are lower, some of the air from the rooms can be re-circulated via amixing chamber and this can result in significant energy savings. Amixing chamber has dampers for controlling the ratio between the return, outside and exhaust air.The AHU is alarge metal box containing separate ventilators for supply and exhaust, heating coil, cooling coil, heating/cooling recovery system, air filter racks or chambers, sound attenuators, mixing chamber, and dampers. AHUs connect to ductwork that distributes the conditioned air through the building, and returns it to the AHU.A heat/cooling recovery exchanger is normally fitted to the AHU for energy savings and increasing capacity.An AHU designed for outdoor use, typically on roofs, is also known as arooftop unit (RTU).The following is just for your reference:Air flow4ROW6ROW8ROWTCSCWaterflowWaterresistanceTCSCWaterflowWaterresistanceTCSCWaterflowWaterresistancem³/hkWkWL/SkPakWkWL/SkPakWkWL/SkPa21108.507.770.381.013.4010.190.623.416.4511.520.766.1364019.4315.320.916.026.6518.831.2614.931.1920.851.4624.8518030.2922.771.4316.139.8727.491.8836.345.8630.192.1559.3558029.3123.131.397.340.3528.501.9216.947.3731.622.2527.7799046.0834.702.1818.961.0142.042.8740.963.6963.513.069.21041063.4046.513.0137.873.8252.323.5310.987.0958.204.1818.11282079.6357.843.6859.794.2365.744.4718.3110.1072.835.2630.31080062.4046.852.9816.082.4456.723.9536.294.9962.374.5258.31409085.3062.634.0631.499.5370.544.7710.8117.5878.545.5617.917380108.7378.645.1854.1127.5888.966.0818.4149.3298.667.1830.420670117.5188.605.6313.3156.33107.687.5129.4180.23118.438.6046.117030103.8875.964.9934.8120.3085.205.7610.8142.1194.876.7917.920980131.1294.816.1956.7153.81107.247.3318.5179.44228.698.4829.524930141.99106.926.8213.4188.68129.869.0929.6217.35142.7710.3746.328890169.72125.988.1319.9222.26151.9710.5141.6234.26157.8311.2214.625650158.78115.217.3759.7188.76131.349.0818.9220.20145.4010.5830.630470173.25130.488.3113.4230.47158.6011.1029.6266.12174.6412.6746.336010204.73154.149.8315.0272.10187.2713.0732.3314.43206.3114.9750.041720245.31181.8911.8022.4320.99219.3415.2545.8338.41227.8416.3221.547250284.63208.7613.6831.1366.25249.5317.0059.5391.14261.3518.8629.152950306.38227.4314.7335.6419.38283.4120.1786.1445.44295.9021.4638.347930280.50208.3713.3919.6368.50251.8417.6042.3387.50261.1718.5121.554520326.50240.0515.5927.6425.50289.1120.3358.8450.50301.1721.5329.561100375.50272.9217.9437.8435.50306.5520.8126.1513.50341.1924.5439.059970360.50264.5617.2227.5468.50318.1822.3958.4496.50331.6623.7324.067210410.50299.1519.6137.0527.11357.4324.4072.9565.50375.5527.0331.874450462.50334.5522.1048.6540.50377.5825.8327.0634.50419.4730.3340.881220504.50364.9224.1151.0590.50412.2528.2229.8692.50457.7133.1044.594760589.50426.0728.1756.5688.50480.7432.9135.5805.50532.9138.5152.198500616.50444.4129.4754.6720.50501.7234.4421.7842.50556.1940.2834.5107720682.50489.4032.6268.9800.50556.5638.2727.3932.50613.0644.5843.3116940731.99527.5533.0173.8880.50606.1642.0933.71018.50668.2048.6952.8124060774.96558.9634.5872.2933.50642.7944.6328.91081.50709.3051.7146.3133930821.00596.8533.9673.21018.50698.4548.6935.21174.50768.7456.1656.0143810842.50624.9440.2819.71102.50753.7052.7142.11269.50829.0960.7067.0153680913.50673.2443.6723.61190.50810.6456.9250.21353.22884.4862.1872.8160720920.50689.7844.0118.91220.50837.3758.3640.01402.99919.6465.5359.51725701010.50749.6648.3123.11323.50904.5963.2848.01391.50938.0166.5428.31844201095.50812.7552.3827.61427.50972.2668.2656.81506.501010.6672.0433.31962701180.50865.4456.4432.51530.501039.5173.1966.51621.501083.3577.5438.8Air-handling unit installation instructionsIn units neighboring, especially the side with maintenance door and external water pipe, enough space should be reserved for filter extraction and maintenance.A horizontal base is indispensable. Any slant base will affect normal water drainage of water pond and working fan's dynamic balance.Air is sucked in by unit. The heating hot water temperature must not be higher than 65ºC. The water must be cleaned (soft water). Awater filter is needed if necessary.The condensate pipe of units must be equipped with steam trap. The height of it can be measured through residual pressure +height of 100nn water (following picture is the specific requirement), and asmooth condensate pipe and drainage slope be higher than 0.005 must be assured.Weight of air pipes and water pipes connected to the units must be born by ahanger or support column not the unit itself.The electric motor power supply must have protection when the power lacks phase or is overloaded. Voltage reduction should be started in amotor with power more than 11Kw. Units power supply is 380V, 50Hz.After the installation, before switching on the power, please rotate the leaves of fan with hand to check if they are in good condition. Don't forget to check the voltage to see if it is the right one, without missing phase or is an imbalance triphase. After power on, first of all, switch on the electric power to check if the fan rotates in the right direction, if not, please change the phase sequence. only without exceptions can the unit be put to use. No empty running for the unit.Before the unit starts, air inlet and outlet valve should be half open. After the start, please adjust the opening space of air valve to make sure that the motor runs within rated current.Air filter should be cleaned regularly. During non-use period in winter, measures of freezing-proof are necessary, or empty the coil to prevent it from frost cracking.After two years of operation, acomprehensive maintenance is necessary for the unit, including cleaning dirt on heat exchanger fins and scale in water pipes.A professional technician is needed if the unit breaks down.Ordering GuidePlease be sure of the size, model, cool and heat quantity and left/right form in selecting air handling unit.Electrical controller is not part of the unit. However, the electric protector and air quantity speed regulation (including variable frequency controller and thyristor controller) is addable according to clients' needs. Neither is inlet and outlet air quantity valve part of the unit. Please inform us before ordering if you need it.Our products are not limited to our routine units.
