Main component for RTR close control air condition

Component name	description	picture
Cabinet	The surface of cabinets is made of the electrostatic spraying cold-rolled plates. They are light weight, high structural strength and appearance of the fluid.The inside door with flame retardant insulation layer level, surrounded with fixed special double-seal, to good insulation, noise and sealing effect.
Compressor	All units are using Copeland scroll compressor, which ensure the high efficiency units, less moving parts, less vibration, and low noise
Microprocessor controller	Unit control system uses advanced Carel microprocessor, thus it is providing more convenient and accurate system monitoring functions and parameter setting. In normal use of the temperature and humidity range,temperature control accurate to within ±1℃, the temperature control accuracy to within±5%
Throttling device	Electronic expansion valve provides highly efficient electronic control of the flow of refrigerant in a precise
Axial Fan	Use world well-know Ziehl-Abegg fan for outdoor unit
EC fan	Use variable speed EC fan for indoor unit and horizontal airflow will save the cost on the energy during operation
Humidifier	The electrode humidifier system is used for the units. The capacity of humidification,water outlet and water inlet which are controlled by a microprocessor.Automatic humidifying tank cleaning procedures to ensure humidifier can maintain normal humidifying efficiency
Heater	The electric heater has a perfect protection and anti-ionizing functions
EU4 Air filter	It is using the fold-plate filter that can be clean. It is made of vinegar synthetic fibers with high dust-rate and low initial resistance characters. The filtering media can be reuse and change easily
Evaporator	We use a highly efficient evaporator with high-quality materials and advanced professional technology. It has a large area of heat transfer
Condenser	Condenser shell is made of anti corrosion materials. Using the external rotor axial fans designed to meet the environment requirement of noise. Fans speed control the speed of different temperature that guarantee good results and energy saving operation
