Explanation: 
High quality compressor 
Considering that the compressor is the heart of the cooling-water machines.Naser cooling-water machines select and use the high quality prototype compressors from Europe, America and Japan, Built-in security protection settings, lowest noise, lowest electricity consumption and longest service life, it will bring you full satisfaction. 
Water tank evaporator 
Water tank evaporator is made with thick stainless steel having automatic water compensation function, with out requiring of installation of expansion water tank makes maintenance more convenient and is fit for high flow rate and small temperature difference and other special applications. 
Water cooling type condenser 
Using the newest CAD/CAM designing and processing techniques, with newest high efficiency external spiral steel tubes from Kobe, Japan which have the features of high capacity of heat dissipating, compactness, the water cooling condenser is manufactured by CNC processing center, having the features of compact conformation, high reliability, beautiful appearance, high efficiency and low energy consumption. 
Fan cooling type condenser 
Fan cooling type condenser is punched by high speed punching machine, cooling fan's quality is reliable, two times of edge flanging making the steel tube and the fan touch more tightly each other result in high efficiency of heat exchange completely adopting imported steel tubes and full automatic bent tube welding technique greatly enhances oxygen leak-proof and completely avoids the leaking of cooling mediums,so,this type of condenser is more fit for the district where lack water or where water hardness is high. 
Unit composition 
The unit incorporating accurate electric temperature control which can accurately control the temperature between ***5℃,built-in compressor overburden protector, circulating water pump overburden brake, system abnormal high and low pressure protector, circulating water pump filter and expanding valve, repairing hard valve interface and other settings is insured to be safely and reliable operated and conveniently maintained.
