Performance characteristics: the exchanger body and four independent filter blocks, the filter block in turn work, work pressure, good sealing performance, wear resistance, long service life. A filter block preheating station and exhaust structure. When changing the net net net new gas can keep changing the net pressure balance, completely solve the "bubble" of the problem. The location is also block the exhaust preheat position, can guarantee to change the network and the network is changing the temperature consistent, to avoid the new block because of the low temperature crystallization and melt fluidity and even crystal.
Scope of application: this type of exchanger for granulation, pipe, sheet, plate, PVB explosion-proof membrane production line, especially has obvious effect in the PET and PP drawing, spinning, EPE, EPS, XPS foam production.
