THERMALCOOL air handling units are designed with excellent quality and performance. It has multi-functional air handling functions, including cooling, heating, humidification, dehumidification and purification.  Each and every individual model and design gives the strength and durability required for industrial and marine applications.  The minimum air volume of the product is 2,000 m3/h and the maximum air volume is 140,000 m3/h. We can also customize designs according to customers' special requirements. The casing can be fabricated with galvanized steel sheet or stainless steel 316L as per customer’s requirements. Power supply available is AC 380V/440V, 50Hz/60Hz and 1Ph/3Ph. Cooling capacity available is from 20 kW to 880 kW and the refrigerant is R407C, R404A, R410A & R134A. We are also able to make customized design as per customer’s requirements.

The standard coil is made of copper pipes mechanically connected with aluminum or copper fins, and internally threaded copper pipes are used to increase the heat exchange area, all of which are contained in a galvanized steel frame.

Below optional coils can be ordered as below:

  • Anti-corrosion coating or electrophoresis anti-corrosion treatment
  • heating steam coil
  • copper fins
  • Stainless steel frame

All coils are selected by software to ensure high heat exchange efficiency under the premise of low pressure drop. All coil leak detection tests are carried out at a maximum of 28 bar, and the coil design is based on a maximum pressure of 25 bar. The condenser drain pan is of dry design and is made of stainless steel 316L . When the air speed is higher than 2.5 m/s , the rear side of the coil is equipped with a water baffle made of SS304 or SS316 .

Other parts are of good quality:

Filters are made of synthetic medium or a glass fiber with G2 to G4 level, mounted on the slide frame or galvanized steel. Synthetic fiber or glass fiber media bag filter, F5 to F9 class, installed in galvanized steel and aluminum alloy frame, with gasket to avoid air bypass.

High-efficiency compact HEPA filter, H10 to H13 grade, fixed on heavy-duty galvanized steel washer structure with brackets, nuts, bolts or clamps.

Dampers should have a high strength extruded aluminum vanes, the ABS drive gear, and should be installed inside / outside. The blades should be equipped with "O" type gaskets. The shaft and control rod should be made of steel or copper, and their design should be suitable for use with actuators. The damper shall be controlled manually or electrically. Final damper size shall be finalized with the customer.

The unit is equipped with a double-inlet backward-inclining centrifugal fan. All wheels are statically and dynamically balanced according to ISO1940 and AMCA 204-G2.5 standards. The motor is a fully enclosed fan cooling type, with an insulation class of F and a protection class of IP 55 . The specially designed motor and fan base frame provides a very simple and flexible installation and maintenance method for fan and motor adjustment. The basic frame is completely isolated from the unit shell to avoid vibration in the cabinet.
The frames are made up of high strength, stability, corrosion-resistant coating, and excellent insulation performance with durable high-quality gaskets to ensure perfect sealing. Double-layer heat insulation board are made of galvanized steel and SS316L material casing is optional. High-density hard CFC (foamed polyurethane) is pressure-injected between two sheets to produce a high-strength insulating double-layer board. The panel only needs to be locked on the frame with screws or springs. The whole plate thickness is 25-50 mm , and the insulation density is 45-50kg/m 3 .

The panel design of each unit is easy to be disassemble and easy to maintain. The unit is equipped with an access door for daily inspection and maintenance. It is recommended to use inspection windows and waterproof lights for the fan part and other required parts.
