1:Strictly obey to produce, inspect, to ensure quality of products
2:The products use high efficient copper pipe with external thread, heat exchange rate is high, volume is low, weight is light.
3:In order to ensure quality, all the products are tested under 2.4MPa pressure.
4:In order to ensure safety while cooperating, pressure vessel has fusible plug, once the temperature of liquid in the vessel
reaches certain degree, the fusible plug will automatically melt and release pressure.
5:There are two end covers on two sides of tube, in order to avoid damaging heat exchange pipe from frozen water, when environment temperature is low in winter.
