Chilled Water Type Fresh Air Handling Unit Features:
1. This is a packaged air conditioner that integrates the condensing, evaporating, and control parts into one unit, first introduced and applied in South America, North Europe, and Australia.

2. It is an air-cooled direct evaporation and expansion air conditioner, eliminating the need for cooling water or chilled water systems. This means no cooling towers, cooling water pumps, chilled water pumps, related piping, electrical controls, or terminal equipment are required, saving user investment.

3. The evaporating and condensing parts are integrated into a single unit installed outside, saving indoor space. Users only need to install ducts, without connecting refrigerant piping. It operates under intelligent control with minimal maintenance.
 
Application Range:
It is mainly used in factories, schools, auditoriums, warehouses, and similar environments.

Structure:
1. Panels and frames are made from galvanized steel coated with polyester powder paint to ensure resistance to atmospheric agents.
2. Direct expansion coils with condensate drain trays.

Hermetic Compressor
1. High-efficiency scroll compressors for the entire range, with built-in thermal overload cut-out and crankcase heater, mounted on rubber vibration dampers.
2. Acoustic insulation for the compressor section and thermal insulation for the coil and fan section, resulting in low noise levels.

Centrifugal Fan
1. Forward curve centrifugal fans for air treatment and axial fans for condensation.
2. Front, side, and underside air discharge options.
3. High external pressure, allowing long air supply distances.

Electric Panel
1. Electric panel includes breakers and contactors for compressors and fan motors, phase sequence relay, and other necessary protection devices for main components.
2. User-friendly line controller.
3. Cooling/Heating/Auto mode.
4. Error indication feature.
5. Timer for on/off operation.

Optional Features:
1. Economizer with fresh and return air dampers and a fresh air hood.
2. Free cooling function for low ambient temperatures.
3. Low ambient temperature control device for outdoor unit operation between -10°C and 20°C.
4. BMS devices available.
5. T3 (Tropical climate) option.
6. Condenser coil guard.
7. Metal or aluminum filter.
8. Air pressure switch for indoor fan.
9. High static pressure condenser fan option with sealed and drained condensing section.
10. Optional water heating coil.
11. Metal or plastic mesh on the condenser coil.
12. Optional supply and return air configurations.
13. Upgraded evaporator fan motor drives.
14. G4 filter, plate, and bag filters available.
