5. Components-air handling unit or air handler
Casing Panel and Insulation
• Double skin construction is provided by sandwich type panels comprising inner and outer painted steel skins and polyurethane foam with minimum 48kg/m3 density, providing a good thermal and acoustical performance
• The gasket liner between the panels and frame ensures the air leakage rate to comply with GB/T 14294 clean air conditioning requirement
• The factory painted steel sheet covered with 6 insulation coatings, complies to 500h salt spray testing, showing an excellent corrosion protection performance


Frame
•Penta-post extra heavy gauge aluminum profiles and strong fiber-reinforced PE corner connection forming the structural  frame
• superior mechanical strength and rigidity to the unit frame and to prevent any buckling or deformation
• Thermal bridge free design, the profiles filled with polyurethane foam for insulation
• Anodizing surface treatment for profiles, corrosion-resistant
• Stainless steel frame available


Famous Brand Fan and Motor
• Fan selection based on the air flow and air static requirement  is done by fan selection software
• Direct driven/ belt driven, forward curve/ backward curve centrifugal fans, and EC fan is available for option
• Nicotra, Kruger, Deton, Yilida is offered as option

• All coils tested at 30bar pressure underwater 24 hours
• Various corrosion resistance coils for option:
-Cooper tube with cooper fins coil
 -Epoxy coated fins coil
 -Electrophoresis fins coil
-Heresite coated coil

High efficiency filter
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.

7.FAQ
Q:What is air handler?
A: An air handler, or air handling unit (often abbreviated to AHU), is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system.
 
Air handlers usually connect to a ductwork ventilation system that distributes the conditioned air through the building and returns it to the AHU. Sometimes AHUs discharge (supply) and admit (return) air directly to and from the space served without ductwork.

Small air handlers, for local use, are called terminal units, and may only include an air filter, coil, and blower; these simple terminal units are called blower coils or fan coil units.

A larger air handler that conditions 100% outside air, and no recirculated air, is known as a makeup air unit . An air handler designed for outdoor use, typically on roofs, is known as a packaged unit or rooftop unit .

Q: What information do you need to provide in order to get a quotation?
A: Generally, we need to know following items:
-Cooling Capacity in KW or RT or Btu
-Cold water conditions if available is better
- Local ambient temperature conditions
-Application
-Electrical power supply, such as 380V-3Phase-50HZ or 440V-3Phase-60HZ or others.
 
If can not give full answers for above items, we can via another way, such as room or building drawing,application,etc

10.Installation instruction or installation photo, project photos

---1. During installation, enough space should be reserved around the unit, especially aside the access door and water pipe, for the repair machine passing. 
---2. The unit should be mounted on flat base (concrete or welded C-channel).  Drainages are available around the base.
---3. Floor drain should be set in the machine room for the discharge of condensing water and washing water.
---4.Pay attention to condensing water discharging; to ensure the condensing water discharge smoothly.
---5. The unit should be installed on a horizontal platform or hanger.  After the unit is installed, connect the kinds of pipes and ducts:
A. The chilled water pipe connection with cooling coil;
B. The condensing water drain pipe connection;
C. Humidifier pipes connection;
D. The connection for the fresh/return air inlet with its air ducts;
E. The wiring connection for the control box.
When connecting the air duct, 100-150mm flexible connection (airtight canvas or artificial leather cloth) should be set between flange and air inlet/outlet, to avoid the air leakage caused by the unit vibration.

The control box normally is installed on the unit cabinet or in the machine room. Please make the wiring according to the related electrical regulation by your country.

---6.After all water pipe, wirings and air duct are correctly connected, the air handling unit can be started.
[ !]The first time starting should be instructed by an experienced person at site, non-experienced person can't operate the equipment without permit.  The defect caused by misuse shall not be our obligation;
[ !] Before first time starting, please remove the temporary fixing plate from the fan and motor;
[ !] The power and voltage supply must be compatible with the unit.  After connecting the power to the motor, start motor first, then check the running direction of the fan. If it is running in opposite direction, please stop and change the phase sequence, then connect the power to motor finally. If there is protection device on the supply fan motor, the motor raring should be connected to ground.  The motor in this unit use "reduced voltage starting".
---7. Adjustment of the driving belt
---8. Before moving the unit, please fasten the damping device.  Putting down should be slowly to make sure that the damping device is forced evenly to protect the damping device.  The connection between damping device and the unit should not be by welding
