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
Fan and motor
•NICOTRA centrifugal Fan or other brand fan;
•Double inlet
•Electric motor driven
•Back curved or front curved
•low noise, high efficiency, stable operation, low vibration, good strength, low bearing temperature rise, and wide working temperature and humidity range.
•Customized configuration of the motor selected high-quality brand-name motor, smooth operation, low noise, long service life, and can be equipped with a specified brand of motor or motor insulation, protection level people according to user requirements, to meet the needs of different occasions.
•EC Fan is optional
• plug fan is optional
Vibration Eliminator
• To reduce the transmission of vibration and noise, fan and motor are installed on an independent complete base frame
• The complete base frame is isolated by deflection type spring isolators
• This unique structure not only reduce the vibration and noise, but also protect fan and motor during transportation
Cooling Coil
Cooling Coil is used to cool and dehumidify the air.Both DX (direct expansion) cooling and CW (chilled water) cooling coils are available for use depending on the system design.
These coils are arranged in rows with different fin spacing.Aluminum fins and copper tubes are used in the design of the coils.The corrosion resistance hydrophilic fins are also used due to its lower cost and lower resistance to the air velocity.
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.
Stainless Steel Drain Pan
• Slop type design, no drain water carryover and keep the pan dry
• Avoid the micro-organisms growth inside the drain pan
Antimicrobial Drain Pan is offered as option
• SteriTouch technology Drip Pan Coating
• Antimicrobial surface
• Good exterior durability and corrosion resistance
• Excellent adhesion
• Non-toxic, comply with BS476 part 7
Electrical control cabinet(optioanl)
•According to the requirements and functions of the unit to design the control console or cabinet
•Auto control each section of the unit to make sure the temperature, humidity and cleaness
•High quality and international brand electrical elements
•DDC and PLC available

7.FAQ
Q:What are the differences between an air conditioner and an air handler?
Air handlers are an important part of your overall HVAC system, but they are not the complete air conditioning system.
An air handler is responsible for housing the equipment necessary to move air through your home or business.In most cases, it is located inside and operates both the heating and cooling systems.Air handlers look like a furnace, and are sometimes even mistaken for one.Air handlers can be made to work with a heat pump or air conditioner.It includes the indoor coil, which depending on the setting your system is running on, is used for both heating and cooling.
Air conditioning units include the condenser and are usually kept outside of your home or business.Air conditioners actively pull heat out of the building through a variety of components configured together, and then this hot air is redirected outside.Throughout the process, air moves through the system via return ducts and over a refrigerant coil.Instead of adding cold air to the room, which is what it feels like, the system is actually just pulling hot air out and then recirculating the same air (without the heat) back into the building.

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
