Plate-Type Heat Exchanger is one of the ideal heat exchanger of liquid-liquid or gas-liquid, which has many advantages like high heat transfer coefficient, small heat loss, compact structure, small occupation, convenient install and washing, widely use and long usage life etc. Compared with pipe-type heat exchanger, this equipment has a 3-5 times in transfer coefficient but only occupy 1/3 in the dimensions, which is used in metallurgy, petroleum, chemical, food, pharmacy, watercraft, textile, paper making areas. It's a good option for heating, cooling, heat recovery or rapid sterilization.
