Air Handler
Overview
GRAD Air Handler 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
↘Panel structure
A: The panel is formed by two layers of colored steel plates. Filler between the layers is high-density polyurethane or polystyrene, which has a better performance in thermal isolation than other materials like glass wool. o ̀ thermal bridge will be produced while working in all weather or working conditions.
B: panels are fixed in a special way, with sealing material to strengthen its thermal and air resistance. This structure has the best performance in thermal isolation, noise reduction and intensity, so it can be used in places require high quality of air.
↘Cooler
The selected parameters of surface air cooler are designed by CAD/coi1 software. The standard cooler normally has copper pipes of φ6. It is tightened by an overall rise up of brass strung by corrugated aluminum fin tubes. Staggered copper pipes have good heat transfer performance, low airflow resistance and superior corrosion resistance, ensuring the cooler has a higher heat transfer coefficient and a longer life.
↘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.
