Evaporator

An efficient evaporator made from quality material with advanced professional technology and featuring large heat exchange area and the realization of higher sensible heat factor of precision air conditioning unit.

Expansion Valve

Expansion valve adopts advanced thermal expansion valves with strong reliability and stability and can precisely control the supply of refrigerant. In order to achieve the reduction of energy consumption for refrigeration equipment, we employ advanced electronic expansion valves in high-performance precision air conditioning units to realize less energy consumption.

Humidifier

An internationally advanced electrode steam humidification system under which the amount of humidification and water inflow and outflow are all controlled by computer, the auto cleaning program for the humidifier cylinder ensure normal humidification effciency of the clinder.

Filter

Air filter which is EU4 standard which is metallic bracket , filtering the dust and particulate effectively by air circulation , then purifying the air environment of telecom room.

Scroll Compressor

The core power of the unit is from Copeland hermetic scroll compressor that guarantees the high efficiency ,low noise and the long life of the unit.

Indoor blower fan

A blow fan adopts direct drive centrifugal fan with backward curved blades, the range of static pressure can be adjusted from 0 to 400pa, realizing the continuous operation of 365 days* 24 hours, 10 years’ average life. 

The high-performance unit employ energy-saving EC fan controlled by 0-10V signal,DC driven and stepless speed regulation,which is more excellent than traditional fan in energy-saving filed.

Heater

An electric heater with perfect overheat protection function and ionization resistance, able to meet environmental requirements of the small heat-load machine rooms for base stations in cold arctic-alpine area.

Condenser

With an enclosure of anti-corrosion alloy that ensures service life and appearance of the is elaborately designed and able to satisfy the environmental protection requirements on noise, and a fan speed regulator that controls the rotating speed under different temperature and ensures sound operating effect and energy saving.

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.
