Product Description

1.Eurostars air handling unit and air handler features
Rotary heat exchanger (heat recovery wheel) is mainly used in building ventilation or in the air supply/discharge system of air conditioning equipment. The wheel transfers the energy (cold or heat) contained in exhaust air to the fresh air supplied to indoor.It's a piece of important equipment and a key technology in the field of construction energy saving.

Rotary heat exchanger section
1. Rotary heat exchanger is composed of heat rotor(wheel), frame, drive system, double purge sector and sealing parts etc..
2. Supply air(SA) passes through half of the wheel, exhaust air(EA) passes through reversely the rest half of the
wheel, meanwhile the wheel is rotating driven be the drive system. Thus, the wheel can be self-cleaning.
3. Drain pan is equipped under the wheel, in case condensed water occurs from fresh air in summer or return air in winter when their temperature is decreasing. Meanwhile, make sure the drainpipe is expedite and water seal is installed.
4. Ice jam might occur on the exhaust side when operating in very cold area, if so, rotary speed reduction or turn-on of bypass is required to ensure safe operation of the wheel.
5. On some occasions with strict cleanness requirement, to minimize the carryover from return air to supply air, exhaust fan shall be placed in the leaving section of the exhaust side to create passive pressure, and the pressure shall be lower than that of supply side, so that the double purge sector can perform more effectively.
6. For easy transportation or easy installation in limit space, the wheel can be cut into segments.

2.Eurostars Air handler,air handling unit, ahu application
EUROSTARS air handling unit can cool, dry, heat, humidify, filter and purify air with silencer function. It can be widely applied in the places where the air needs to be conditioned in a centralized way, such as shopping malls, hotels, office buildings and stadiums, as well as other purification air-conditioning places, such as hospital operating rooms, pharmaceutical, tobacco, food, precision instruments manufacturing rooms.

Filters
Filters are to remove particles and contaminants of various sizes from the air. The type of air filter being used will very much depend on the application of the system.
Panel Filter is a flat and rectangular in shape and provides a minimum low efficiency filtration which is acceptable to the air conditioning industry. The high velocity filter
is arranged vertically whereas the low velocity filter is arranged in V shape. Typical air velocity that moves through the filters is in the range of 2-3 m/s.

HEPA Filter is very efficient and is able to achieve efficiencies up to 99.97%, removing minute particles and airborne bacteria from the air. It is usually used in clean room
applications such as semiconductor production floor, operating theaters and critical processes.

Electrostatic Filter is used to remove particles from the air by using highly charged electrodes that ionized the air.
Bag Filter is able to remove dust particles and is thrown away after use.
Roll Filter is used for high velocity filtration where the used part is rolled up automatically/manually.
