3. Product Feature And Application of The CM Series Precision Air Conditioner 20~100kw


Product Features:

High Efficiency and Energy Saving:

Perfect control and setting function, easy to use, easy to maintain, strong adaptability.


The design of large air volume and small enthalpy difference is suitable for heat dissipation of the main equipment in the equipment room, and provides continuous and stable temperature and humidity environment for the main equipment.


Using Emerson "Wheel" brand scroll compressor, specially for high performance requirements for adjustment.


V-type evaporator with large area and high heat dissipation efficiency adopts internal threaded tube design to ensure heat exchange efficiency and improve evaporation effect per unit area.


Quick Dehumidification Design: 

Aluminum alloy fin, fast temperature rise, over temperature protection, ensure dehumidification accuracy, reduce reheat power consumption.


The far infrared humidification system can achieve instant humidification under any water quality condition, with greater humidification capacity and higher efficiency.


Danfoss electronic expansion valve, good superheat control characteristics, high reliability, fast response, more accurate control.


The EC fan adopts low-current soft start technology, automatically adjusts the fan speed, dynamically outputs the air volume, and saves energy by more than 30%.


The lower air supply fan adopts "sinking type" design to lower the fan unit to the floor for air supply and further improve the air supply efficiency.


The intelligent controller adopts a 7-inch LCD screen with additional function keys to avoid damage caused by static electricity of the human body.


The advanced controller automatically balances the operation and wear of the components to prolong the life of the system. The power distribution part adopts the separation design of strong and weak electricity to avoid the interference of strong current to the signal line.


Outdoor fan adopts stepless full speed control, to ensure that the system runs healthier, more energy saving, lower noise, outdoor fan maintenance requirements are very low, suitable for all kinds of climate conditions, outdoor structure adopts fatigue resistant, corrosion resistant aluminum, prevent coil wear.


Perfect Control and Setting Function:

Intelligent and stable constant temperature and humidity function, the controller adopts advanced fuzzy logic PID self-tuning technology, with multi-level password protection, can effectively prevent illegal operation.


The whole Chinese large screen graphics display, with multi-level password protection, can effectively prevent illegal operations, through the menu operation can accurately understand the running time of the main components, equipment running status.


The expert fault diagnosis system automatically displays the current fault information, which is convenient for maintenance personnel.


It has the function of self-start by incoming call, and can set delayed start time. It can store up to 400 historical alarm records for reference.


It has three remote functions of telemetry, remote communication and remote control, realizing real-time control and point-to-point control.


It has standard RS485 monitoring interface and adopts the communication protocol of the Ministry of Industry and Information Technology.


The pressure difference detection sends alarm signals when the air flow of the fan is lost due to the fan failure. The powerful teamwork working mode can realize the teamwork control of up to 32 units and can be divided into multiple groups.


According to the load of the machine room, the number of units can be dynamically adjusted to coordinate the work of the unit in the unbalanced load of the machine room. The flexible switching function of master and standby units can realize the automatic switching and rotating function of the unit.


Easy to Use, Easy to Maintain, Strong Adaptability:

Small footprint, 100% full frontal maintenance, customized design according to special needs, environmentally friendly design, compatible with R22 and R407C refrigeration system.


Modular detachable handling structure, can be disassembled and installed according to special site requirements.


Ultra wide input voltage range, with a variety of power protection functions, to provide a suitable environment for different temperatures (including low temperature start) configuration.


A power SPD is optional to provide more reliable security, and a water leakage detector is optional to provide water leakage alarm and linkage functions of the whole system.


Provide ultra-far installation distance and ultra-high drop scheme to ensure normal start-up operation of the unit.


Integrated disassembly fan, heating, humidification system, high reliability, long life, easy maintenance.


According to 365 days a year, 24 hours a day continuous operation long life design, high stability, low maintenance.



Medium and large switching and mobile rooms, computer rooms and data centers, high-tech environment and laboratories, industrial control rooms and calibration centers, UPS and battery rooms, biochemical culture rooms, hospitals and testing rooms.
