Air Handler Unit
Overview
GRAD Air Handler Unit covers vertical (air volume from 2000 ~ 60000m3 /h), horizontal (wind increased from 2000 ~ 60000m3/h), and ceiling-type (air volume from 1000 ~ 16000m3/h) three series of air-handling unit to meet customers’ need of cooling, heating, humidification, dehumidification and so on. It is widely applied in hotels, theaters, shopping malls, office buildings and a variety of places requires comfortable environment. It also can be used in electronics, chemical, medical, pharmaceutical, cigarettes, food, light engineering and other industrial buildings.
The characteristics of air-handling units
↘Frame structure
The unit adopts aluminum alloy frame structure or metal frame structure, it has the following features
A: Good performance in mechanical strength, light in weight, corrosion resistance, beautiful shape and accurate size.
B: Flexible assemblage, very convenient to install, remove and maintenance. Also, it has longer service life than steel structure.
↘Fan, motorl
A unit adopts centrifugal fan with both air inlet. The fan runs smoothly in the rigorous static and dynamic balance ̀ test.
B: With ball bearings sealed, and functions of pre-lubricating, self-aligning, self-locking, automatic thrust, etc., the fan is maintenance-free in normal use.
C: Fans of a small model unit are driven directly by external sub-motor, no belt, and easy to maintain.
↘Filter
Unit filter is coarse plate. Filter material is cleanable convex Nylon net.
Air handling unit performance (Table I ~ Table VI)
1. Air-conditioning working condition means that the dry bulb temperature of intake air is 27℃, wet bulb 19.5℃ while cooling, and dry bulb 21℃ while heating.
2. Fresh air working conditions (l00% fresh air) means when cooling, dry bulb temperature of intake air is 350℃, wet bulb temperature 28℃, dry bulb temperature of intake air -5℃ while heating.
3. Cold water temperature: supply water is 7℃, back water is 12℃. Hot water supply temperature is 60℃.
4. The motor power values from table I to tableVI correspond with its different residual pressure. The residual pressure is flexible, which can be decided by our customers according to needs.
5. The noise values from table I to table VI are tested in the muffling section 1m (GB/T9068) away from each surface of the units.
Ordering Guide
Please 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. According to clients’ special needs, unit can be equipped with additional electrical (auxiliary) heater, humidifier (steam humidifier, wet membrane humidifier, high-pressure spray humidifier and electrode humidifier), silencerand so on. Our company follows the principle of constantly improving our products. Please kindly excuse us if we do not inform you in time about changes or improvement of product performance, specifications, and materials, and keep in touch with us to obtain the latest information.
