non-detachable spiral heat exchanger(stainless ste

non-detachable spiral heat exchanger is made by the two rolling forms two uniform helical channel, so the two heat transfer media counter-current flow of the whole can be greatly enhanced heat transfer effect, even small temperature difference between the two media, but also achieve the desired the effect of the heat exchanger. Nominal pressure has PN 0.6,1.0,1.6,2.5 Mpa (means of access under the maximum working pressure), according to materials can be divided into carbon steel and stainless steel. Single piece of equipment can not meet the application requirements, you can use more than one portfolio, but the portfolio must meet the following requirements: parallel combination of series combination of the same equipment and channel spacing. Mixed combination: a channel parallel, a serial channel.
