The unit uses high efficiency heat exchanger with advanced, unique shape design and systems. Units can be installed directly on the roof, or other well-ventilated place outdoors, without a separate room, space saving construction. Compact shape, appearance, unit uses "W" type coil design, space utilization, small unit size, in order to adapt to the outdoor weather conditions to ensure that the unit has a good operating results during the life cycle.
Friendy choose to use environmentally R407C, R134A or R410A refrigerant ect.
There may be change of the dimensions without pre notice. For accurate you are welcome to ask us for installing drawing.
Compressor
Select semi-closed 5:6 asymmetric twin-screw compressor from world-renowned brand. The possibility of shaft seal leakage is zero. Using a rotating exhaust design, the lastest development of the fourth generation line, optimize the circumference speed, excellent design of gear so that the unit has higher compression efficiency. Motor chamber compression chamber integrally cast, high precision. Double pressure compensated rotor housing, very strong, no expansion even in the state of high pressure, and it effectively reduces the noise.
Heat exchanger
The condenser and evaporator of this series unit adopts shell and tube heat exchanger, using new high efficient heat exchanger structure. Heat exchanger adopts the most advanced and effcient heat exchanger tube bundle with unique geometric characteristics and enhanced tube nucleate boiling required vaporization core, strengthen the fluid in the tube and delay perturbationat the same time, the water side fouling, heat transfer enhanment, the inside wall in order to get the best performace, comparade to the previous design, the unique design of the heat transfer efficiency is increased by 30%.
Evaporator evapotation tube with inner grooved on outer concave tooth enhanced heat transfer technology, condenser tube with inner grooved cutter teeth technology, improves the evaporator and condenser heat transfer efficiency and the evaporation temperature, and improve the energy efficiency ratio for the unit.
PLC
A good Chinese-English interactive interface is to achieve automatic control function before the LCD display real-time statues of the machine work, precise monitoring unit operating at optimun state, the touch pannel sealed, waterproof, dustproof, corrosion-resistant, long-key life. Equipped with cooling pumps, cooling water pumps and cooling tower fan interlock control function.
