CJA Series Rack Mounted Precision Cooling Unit for High Density Server Rooms

Introduction                                      

COOLNET CJA Series Rack Mounted Precision Air Conditioner is a cabinet-level temperature control product specially designed for integrated cabinets, micro-modules or high heat density data centers. It can be placed close to the heat source in the cabinet and it can accurately handle the high sensible heat generated by the equipment in the cabinet. It can effectively prevent the generation of local hot spots, reduce the return air distance, increase the return air temperature, improve energy efficiency ratio, have significant energy saving effect and effectively develop green data centers for long term.

Advantages                                        

High-level Configuration

• High-efficiency inverter compressor, ultra-precise PID control, more precise temperature control. The well-known EC centrifugal fan can adjust the air volume output ratio in real time as needed
• Equipped with electronic expansion valve, smoothly adjust the throttle opening, realize precise adjustment of the unit.
• Outdoor motor chopper speed regulation, which can realize 25-100% wide voltage speed regulationcontrol.
• R410A environmentally friendly refrigerant design.

Safe & Reliable

• Very wide grid adaptability, can meet 土 209% voltage range, adapt to various harsh grid environments.
• Multi-drainage and anti-back flow design to prevent cabinet flooding.
• Intelligent self-detection of refrigerant capacity and intelligent early warning to ensure the safe operation of the refrigeration system

Easy Installation & Maintenance

• Standard modular design to fit into standard server racks.
• Thedesign of plug-in terminals on the fan side and the whole machine makes the whole machine easy to maintain andfast to install; it occupies a small area and has 100% full frontal maintenance.
• Refrigeration piping is connected with quick couplings.

Features                                   

• Embedded in the cabinet design, occupying little space, saving the area of the server room and reducing space cost for customers.
• Close to heat source cooling, zero loss of cooling capacity, reduced energy consumption, and improved efficiency.
• DC inverter compressor, dynamic cooling, steplessly adjustable cooling capacity, matching IT load operation Pull-out design, easy installation, and maintenance save operation and maintenance costs.
• Can be placed in any cabinet, flexible and suitable for various needs of customers.The building and maintenance are flexible and efficient.
