Vacuum Calibration Tanks
ESI’s Vacuum Calibration Sizing Tanks are designed for the processing of plastic profiles in a variety of rigid and flexible materials. Tanks can be supplied in a variety of cross sections and lengths with different manifold and cooling options. ESI also offers hot water annealing of the front section to minimize bow in profiles with uneven thicknesses, allowing the product temperature to drop below the glass transition point before cooling with chilled water. This greatly reduces bow and camber on many profiles.
Heavy-duty bulkheads are fitted to the front section for mounting of customer’s calibrators. Product can be submerged or spray cooled, depending on options chosen. All tanks are manufactured of stainless steel and incorporate non-corrosive internal components. Standard features include high performance liquid seal vacuum pumps for accurate and consistent vacuum control and multi-directional tank movement with hand wheel adjustment.
Profile calibration tanks also feature multi-port water and vacuum manifolds with individual control valving, full length and width stainless steel overflow trays. All ESI tanks are available with optional features such as closed loop circulation systems with high output pumps and stainless steel reservoirs, multiple vacuum pumps.
