Technological Room Precision Air Conditioning Units , CRAC Air Conditioning Unit

Product Introduction

Precision air conditioning controls the ambient environment by providing constant temperature and humidity conditions to costly and sensitive sophisticated electronic equipments throughout the year. This is in contrast to normal air conditioning which provides only the cooling comfort to people sitting in a room.

Benefits

• Computer room and data center
• Switch room and mobile center station in telecommunication
• High-tech environment and lab
• Industrial automation control room and precision manufacturing workshop
• Standard test room and calibration center
• UPS and battery room
• Test room in hospital
• Biochemical culture chamber

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

Sensible 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.
