With multi-direction air flow supply, automatic swing wind, users can set auxiliary wind gap to send part of air to other place, so as to improve the indoor temperature and the air flow uniformity. System adopts big diameter vortex centrifugal fan to make running silently, and optional anion generator to make pure and fresh indoor air.
Ultrathin frame, min-thickness for frame is only 260mm, users can chose installation direction for connection pipe depending on spot situation, the overall dimension for part of unit is only 590x590mm easy installation with low installation cost.
Remote control is available, flexible control method.
High lift water pump design (750mm); Disposal of condenser water pipes is easy and flexible.
Water level switch protection ensures no water leakage, water in the discharge pan can be
discharged manually; and the water holder pan is designed with discharge hole, which can
discharge the remaining condenser water on time, so as to reduce the possibility for bacteria growth, meanwhile discharging dirt in the regular time reduces clogging probability for water pump.
â??Câ?? type heat exchanger can aid terminal air flow and the uniformity for cooling system, the effect for 4-way air-out can be more balanced, and system leak out possibility can be lower. Hydrophile aluminum coil fin can greatly reduce condensation water remaining on the fin, therefore it reduces the windage and the effect for heat exchange is also improved.
Available for BMS concentrate intelligent control system. And some more designs for easy installation including built-in water valve (optional) for easy exterior connection installation, hand protection grilling and stainless steel soft pipe connection.

protections.
Testing:
Condenser coils are leak tested at 450 psig after production and the entire condenser unit is tested at 350 psig working pressure after production.
In all TI UNIT air handling units the frames are from aluminum profiles while the chassis and body panels are made from galvanized steel sheets in appropriate thicknesses.
All units are completely painted in the proper thickness.
Blower(S):
Double width-double inlet centrifugal fans with forward curved blades are normally used for low pressure drop requirements as opposed to fans with backward curved blades which are for high pressure drop applications. Fans and housings are made of galvanized steel each set off a plus other related components such as shafts are statically and dynamically balanced, shafts are selected from proper material and size. Other power transmission components such as pulleys and belts are also suit ably chosen depending on the required fan speed and electric motor power.
Fan(s) and the corresponding electric motor(s) are installed on an independent chassis which is itself installed on the main chassis using vibration dampers in order to eliminate transfer of vibrations to the structure. To further reduce the effects of vibrations, fan outlet (s) are also connected to the structure via flexible material such as canvous.
All 380V/3/50Hz electric motors are selected with insulation class of (f) and ingress protection of (IP- 54). Electric motors with ingress protection of (IP- 55) are also available upon request.
Coil (S):
Cooling and heating coils or either one of the two depending on the Requirement May be installed. Cooling coils are available in two, types of chilled water and direct expansion (D.X.) as per clients requirements. The chilled water coils are constructed of 5/8 O.D copper tubes plate finned (8, 10, 12 or 14 FPI) in aluminum or copper upon request.
The D.X. Coils are constructed of 3/8 OD copper tubes also plate finned (10, 12 or 14 FPI) in aluminum or copper as required. The chilled water for cooling coils in to be supplied by a water chiller and in the D.X. coils cooling is provided through the use of refrigerant such as R-22, R-407c or R-134a. Chilled water coils may be requested in 4 or 6 rows and as to the D.X. coils, they are available in 4 or 6 row configurations. Heating coils are available in two types of hot water and steam. The hot water coil similar to chilled water coil is offered in 1 or 2 row configurations. Steam heating coils are constructed of 1/2 seamless steel pipe spiral finned in aluminum or copper. Coils in 1 & 2 -row configurations are available upon request.
Mixing box:
Fresh and return air streams are mixed in the mixing box .An independent air damper is included for each air stream. Air Dampers are manufactured from aluminum in opposed blade configuration and are air sealed through the use of rubber strip gasket. Damper actuators ma y be easily installed when required. Washable aluminum filter modules 2 inches in thickness are arranged in (V) type configuration inside these boxes. Housing for
