Heat Exchanger Plates Material
The key point to reduce the thermal resistance of the phe fouling layer is to prevent plate fouling. When the plate fouling thickness is 1 mm, the heat transfer coefficient is reduced by about 10%. Therefore, it is necessary to pay attention to monitoring the water quality at heat exchanger both end side to prevent plate fouling and to prevent the inclusion of impurities in the water on the plates. Some heating units add chemicals to the heating medium in order to prevent water theft and corrosion of steel parts. Therefore, it is necessary to pay attention to the water and viscous agents causing debris to contaminate the heat exchanger plates. If there is sticky debris in the water, it should be treated with a special filter. When using a drug, it is advisable to choose a non-stick agent.
