Product Description

Advantage:

1.Applied to dry areas;

2.Compact structure, installed on the roof, convenient for installation, do not take up too much space ;

3.Sufficient external static pressure, suitable for connecting air duct system, reduce indoor noise greatly;

4.Cooling capacity:meet different requirements;

5.The framework of units is anti-cold bridge aluminum alloy, which eliminates cooling leakage and condensate water due to large temperature difference between inside and outside.

6.The main parts are imported quality products, with excellent performance;

7.The evaporator and condenser adopt the technology of enhancing heat transfer, which makes the exchanger of high efficiency and save energy.

High quality control component

It strictly complies with CE and IEC standards and is empowered with advanced electric control technology and able to work under a power source of 380V±20%.
In addition, it is installed with a power supply protection module, enabling it to make a selection of protective value in a range of 380V±50%.
When voltage goes beyond the selected range, it will automatically protect the unit.
While when the voltage becomes normal, it will automatically restart the unit.

Scroll Compressor

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

Filter

Air filter under G4 standard which is metal tank bracket , filtering the dust and particulate effectively by air circulation , then purifying air environment of telecom room.

Evaporator

An efficient evaporator made from quality material with advanced professional technology and feature large heat exchange area to get 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.

Indoor blower fan

A blow fan adopt radial flow fan with reverse blades and  electronic steering DC dynamo, the range of static pressure can be adjusted from 0 to 400pa, realizing the continuos 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 step less speed regulation, which is more excellent than traditional fan in energy-saving filed.
