Product Name:Screw type chiller

machine unit features
Adopt international famous brand dual screw cooling compressor,there is efficient,low noise, low abradate and long life using.
Tubular condenser,evaporator adopts dual sides strong heat exchange tube, highly improved heat exchanging efficient; heat exchanger compact structure ,disassembled plate,easily

cleaning and maintenance,A part of machine unit adopts dual heat expansion valve design control, to ensure rated ability,widely working system, cooling controlling will be high

precision, keep reliable working and good status.
comprehensive safety protection
1、discharge line valve:ensure compressor run-stop later,preventing high pressure discharge end gas backflow
2、phase sequence:prevent power netting through voltage, less voltage,less phase protection,reverse protection ,compressor reversal and damaged.
3、oil heated protection：before running,strong setting oil heat program,ensure engine oil dilute strength.
4、compressor inner motor heats protection:prevent to damage the compressor because of the overload or badly condition leads the high temperature.
5、high and low pressure protection:when meeting badly work and fault ,the high and low pressure switches to protect the compressor and system.
6、safety valve:ensure the condenser working in the safe range.
7、water flowing protection:preventing the running if no water come.
8、anti-icing protection :machine units running preventing the running if no water come.
9、overload protecrion:soft and hard dual protection,ensure compressor overloads safety.
10、oil pressure protection :when machine unit running,because of system oil not smooth,to lead the pressure not enough,timely protect compressor.
11、oil lever protection: protect compressor during less oil.
12、cooled tower fans overloads protect:ensure cooled tower motor overloads safety.
units using widely as below:
Al Oxidation, Hard Al Oxidation, chromed,molding injection, Extruding,foaming Machinery,bottle Blowing And Film Machine ,Etc.
