Features of product
Compressor: Screw type, smooth operation, the vibrate, noise, activate the torque are all less than reciprocating and centrifugal type. No clearance loss, high volumetric efficiency. Attached unloading device for energy control, R22 refrigerant.
Condenser: shell & tube type, High heat transfer efficiency. The shell is made of seamless steel tube, which by the antirust processing, 410PSI pressure. 150PSI pressure of tube side, Seamless copper tube and pin hinge teeth cooling fins, double water circle Double to achieve the best effect of heat transfer. Straight pipe easy cleaning and maintenance, end cover is made from cast iron, two end cover interchangeable facilitate change up direction, and attach the relief valve, safety valve, etc.
Evaporator: Direct expansion shell & tube type, 350SPI pressure. Surface with flame retardant low thermal mass materials insulation, with refrigerant evaporation pipeline which use seamless steel tube. The cooling fin is internal thread type, good cooling effect, 150PSI pressure. Water flow on the refrigerant pipe, add PP manger to make the chilled water roundabout flow up and down the screen, increase the heat transfer efficiency.
Refrigerant pipeline: contains high pressure check valve, expansion valve, solenoid valve, fluid flow check valve, window, moisture indicator, filter drier and other accessories. Composite evaporator have their pipeline respective, System unbalanced situation will not occur.
Control box: including activator, delay switch, control relay, lack phase inverse phase protector, cease to reactivate switch and overloading protector, indicator light etc. And chain with external water flow switch.
Frame of unit: with a thick steel plate and Angle steel, channel steel, durable and never deformation. Antirust processing on the surface. With shock resist on footstand for compressor.
