DRA 25KW-50KW Single system

Category Large and medium precision air

Deeray CRA series large and medium-sized precision air conditioners are specially designed to ensure high precision temperature and humidity environment. It adopts a modular structure, and different modules can be combined to achieve different cooling capacity. The cooling capacity of air conditioner covers from 25kW to 100kW, and the refrigerant can be an environmentally friendly R410a.

The unit adopts a modular design to reduce the area occupied by the air conditioner in the machine room, and can be carried in different modules to reduce the difficulty of carrying and avoid the quality risk caused by the on-site assembly of modules.

 Deeray CRA series precision air conditioners have a variety of air return modes, such as upper air channel supply, upper air cap supply, lower air supply, EC fan sinking air supply, etc. There are options of single cooling type, single heating type, single humidification type and constant temperature and humidity type etc., which can be selected and matched according to the on-site situation.

  • Features
  • Specification Details

Product advantages:

l  The unit has a wide range of adaptation, can be used in any computer room nationwide, in the outdoor temperature range of -40℃ to 45℃, Liyao air conditioners can run well.

l  A wide control range and high control accuracy:

        Range: temperature 15--32℃, humidity 30--80%

        Accuracy: temperature±1℃, humidity±5%

l  The unit adopts a modular structure, and can be carried in different modules to avoid the quality risk caused by the on-site assembly of modules.

l  The unit is with full frontal maintenance, and there is no need to leave maintenance space on the side and back.

l  Modular structure, the unit covers only a small area.

 

High-end configuration:

High-precision control system

l  Standard 7-inch color touch screen, good man-machine interface, high-precision control, and the control is accurate and reliable, can display:

Ø  Unit parameters

Ø  Running status of the unit

Ø  Operating status of main components

Ø  Operating time of the unit and the main components

Ø  Real-time alarms and historical alarms

Ø  The curve of temperature and humidity

Ø  Other parameters

l  The control system adopts three levels of password security protection, so that you can have different levels of control for different people.

l  With the group control function, using a more reliable CAN group control mode, it can achieve group control of 32 units, to achieve the polling, hot backup, fault backup, to avoid competitive operation and other functions.

l  The standard with RS485 interface, supports ModBUS protocol, SNMP card can be configured, and TCP/IP can be selected.

l  With a variety of protection functions:

Ø  Power protection

Ø  Water leakage alarm

Ø  Temperature and humidity over-limit alarm

Ø  System device protection

Ø  Other alarm protection

Evaporator

l  The evaporator of the unit adopts the "A" type or "V" type design concept, with the internal threaded copper pipe, hydrophilic aluminum fin production, compact structure, with the minimum space to obtain the maximum heat exchange effect.

l  Two evaporators are used for each refrigeration system, the surface air volume of evaporator is even.

 

Scroll Compressor

l  Using a valley wheel scroll compressor, the stable design achieves high reliability and durability. It is able to achieve low noise, low vibration and high energy efficiency during the entire operation.

l  There are few activity parts in scroll compressor, so that the noise and vibration of the unit is reduced. The compression process of compressor is continuous and stable, and the scroll compressor without high and low pressure valve which will reduce the valve loss, prevent liquid strike and low starting current.

l  Equipped with high and low voltage protection function, safer operation.

 

Throttle Device

l  Thermal expansion valve or electronic expansion valve are available.

l  Fast adjustment and precise flow control to ensure the system runs stably in various environments.

 

Outdoor Unit

l  The outdoor condenser adopts copper tube and aluminum fin material, which has a large heat dissipation area, to reduce wind resistance and maintenance times.

l  The outdoor units adopt aluminum alloy shell structure, which can adapt to various harsh environments.

l  The outdoor fan adopts high-efficiency axial flow fan made by German ZIEHL-ABEGG, and equipped with a self-developed fan controller, which can run stepless speed regulation according to the pressure of the refrigeration system, ensuring the stable operation of the system in a wide temperature range.

l  EC fan is optional to achieve energy saving and high efficiency.

 

EC Fan

l  It uses aviation composite material anti-corrosion blades, light weight, high efficiency, low energy consumption.

l  EC Fan adopts brushless DC motor, which can run 0-100% stepless speed adjustment. It is energy saving, high efficiency and low noise.

l  The EC fan adopts soft startup to reduce the impact on the power grid.

 

 

High-end auxiliary heating configuration

l  Configured with semiconductor PTC ceramic electric heater, which heats up quickly, and can achieve automatic temperature adjustment and heating evenly.

l  The electric heater adopts multi-stage control, which is more suitable for the high precision of temperature in the machine room.

l  Configured with over-temperature protection device, it is safe and reliable.


Humidifying unit

l  The electrode humidifier can wash the unit repeatedly. The humidifier has the advantages of small volume, large humidification capacity, fast humidification speed and can produce pure steam and so on.

l  Humidifiers can be washing repeatedly on-site to reduce maintenance costs.

 

Optional Spare Parts

l  Long coupler

l  Low temperature parts

l  Belt leak

l  Lightning protection

l  Others
