The evaporator adopts a reinforced copper tube with inner and outer threads, the copper tube has a good cooling effect. The evaporator barrel is insulated with a 25mm thick PE insulation board. No condensation and less cooling loss.
The condenser adopts German and Japanese original copper tubes, which are processed into trapezoidal low-rib tubes to enhance heat transfer capacity. The inner surface of the copper tube becomes
● Screw Compressor(Bitzer/Copeland/Hanbell) which is 20-30% more energy efficient than the general compressor.
● This central air cooled chiller has obtained patents from many countries in Europe and America and has passed the ISO9001:2000 international quality certification.
● Efficient 5:6 patent asymmetrical gear shape.
● Capacity control can be four-stage (100%-75%-50%-25%) or three-stage (100%-66%-33%) and non-stage control system.
● The combination design of 11 bearings and A-type axial thrust balancing drum greatly increases the bearing life by 2.5-3.5 times.
● High-efficiency silicon steel plate with special groove design and omni-directional cooling flow to make the compressor motor perform at the highest efficiency under any load.
● The unique built-in hydraulic system ensures the best lubricating effect of the compressor without oil pump.
● Multiple refrigerant options. In addition to R22 refrigerant, environmentally friendly refrigerants such as R134a and R407c are also available.
● All-round compressor capacity ratio (V1=2.2/2.6/3.0/3.5) can be selected, which can effectively avoid additional energy consumption due to compressor overload or insufficient compressor pressure.
Pressure protection, overload protection, anti-freeze protection, delay protection, over-temperature protection, water flow protection.
