BHBR semi-soldered plate heat exchanger (ammonia evaporator) specifically designed in the refrigeration system; The ammonia takes the soldering channel, while the secon dary refrigerant (calcium chloride solution, ethylene glycol, etc. ) takes the spacer channel; This kind of structure ensures the reliable sealing of ammonia-side channel as well as boasting the dismountable advantage. Besides, it is also applicable to the vapor--liquid heat exchange with phase change and liquidliquid heat exchange without phase change, which require high safety.

At monment, ourcompany have three types of ammonia evaporator, BHBR0.25, BHBR0.35, BHBR0.65.
