High reliability

Providing Constant temperature & humidity, Cleanliness environment to ensure the main equipment run in good condition. All-day running design can guarantee the main equipment safe operation. All parts had passed severe test and confirmed stable and reliable before delivery.

High energy efficiency

Heat ratio is up to 91%. Compressor energy efficiency ratio is over 3.1, and chilled water cooled unit’s cooling energy efficiency is larger than 25. The optimal and high efficiency compressor and fans. “W/M” type evaporator with super large heat exchange area. Independent air duct design can reduce air resistance significantly and minimize fans power. Variable frequency design on ODU is more efficient and has longer working life. Advanced control logic can effectively avoid competitive running and output cooling capacity according to actual cooling capacity demand.

Easy maintenance

Front panel maintenance: All maintenance work can be operated from front panel. Air filter with metal frame: Cleanable repeatedly, low maintenance cost Self-cleaning humidifier: lower maintenance work Modular design with least spare parts Pressure difference monitoring for air filters can detect whether air filters was blocked or not.

Multiple types

Wide capacity range: air cooled type(5kW~120kW),Water cooled type(5-120KW),chilled water cooled type(30kW~200kW).

Multiple cooling mode: air cooled, water cooled, glycol cooled, chilled water cooled(with single/dual coil), air cooled & chilled water cooled, air cooled & free cooling, Freon pump free cooling.

Multiple air supplying modes: cap tuyere mode, air duct mode, floorboard mode. Multiple refrigerant types: R410A, R407C, R22. Wide ambient

1. IDC rooms solutions: Coolnet precise air conditioning can control temperature, humidity and particle filtration within tight tolerances 24 hours a day and can be remotely monitored.

2. Higher reliable scroll compressor: Famous brand, Copeland, high efficient scroll compressor.

3. High efficient evaporator, energy-saving dehumidify

4. Immersed electrode humidifier: High reliability, well-known brand, Carel.

5. High efficient indoor & outdoor motors: Well-known brand, Ziehl-Abegg.

6. Double wall casing design, improve heat insulation

• Heat-insulated casing can prevent the condensate from the unit body.

• Galvanized steel sheet of nitrogen treatment and powder spray coating make the casing of indoor unit anti-rust and fire resistance.

7. Accurate microprocessor control technology

8. Air plenum box as optional (only for top delivery models)
