Work Condition: 1)Refrigerant side(In the tube): R22,R134a,R407c,R410a etc. 2)Water side (Between the tube and PVC-U shell):Nature water,sea water,salt water ,swimming pool water or other corrosive solution. Material: 1)Heat transfer Tube: Pure titanium tube. 2)Shell: PVC-U. Features: 1)Usually used for heating. 2)Pure titanium tube has super strong corrosion proof ability and high intensity. 3)The seamless titanium tube was tested by 4.0MPa pressure precise Halogen Leak Detection to make sure the tube is strong and not leakage . 4)The PVC-U shell was tested by 0.2Mpa water pressure to make sure the water system not leakage . 5)Working temperature:(1)PVC shell : -5 Deg C to40 Deg C, (2)PP shell : -10 Deg C to 75 Deg C, (3)PE shell : -30 Deg C to 40 Deg C . Application: The heat exchanger are widely used for pool heat pump, heating machine, water&ground-sourced heat pump ,heat pump water heater,industrial heat pump,swimming pool etc. Notice: 1) The data list is our suggested data, We can produce any capacity heat exchangers according customer requirement and design. 2) To guarantee constant inprovement of technology , the parameters shall be changed without further notice.
