Calif.-based George Fischer Inc. reports its Calorplast Flexible Heat Exchanger is designed to
prevent particulate buildup with fluids containing fibers or other suspended solids, while also
allowing efficient reclamation of reusable energy. Suitable applications include commercial
laundry, wastewater treatment and heat recovery. Smooth-walled tubing elements within the device
attach to a special feed and return flow manifold at one end only. The free ends move inside the
chamber to prevent plugging or solids buildup on the tube wall.Calorplast heat exchangers can be
custom-designed using polypropylene (PP) and polyvinylidene fluoride (PVDF). PVDF versions are
rated for 230 psig at an ambient temperature of 68°F.
