Heat exchanger replaces tandem foam extruder.A combination heat exchanger heat exchanger Any of several devices that transfer heat from a hot to a cold fluid. In many engineering applications, one fluid needs to be heated and another cooled, a requirement economically accomplished by a heat exchanger. and static mixer A static mixer is a device for blending (mixing) two liquid materials. The device consists of mixer elements contained in a cylindrical (tube)or squared housing. The static mixer elements consist of a series of baffles that are made from metal or a variety of plastics. from Fluitec Georg AG in Neftenbach, Switzerland, is being used to replace the second cooling extruder in tandem Adv. 1. in tandem - one behind the other; "ride tandem on a bicycle built for two"; "riding horses down the path in tandem" tandem extrusion of PS foam. At four commercial installations, a 15-in.-diam. Fluitec CSE-XR unit mixes and cools PS foam to 230 to 248 F, producing insulation and construction sheet with high homogeneity Homogeneity The degree to which items are similar. and uniformity. The heat exchanger can replace the tandem extruder for relatively low foam outputs of 220 to 1000 lb/hr. For higher outputs, the heat exchanger is used together with a tandem cooling extruder, raising the extruder's output and improving thermal homogeneity.
