A new combination dry-calibration- table/vacuum-tank system from Conair can replace high-horsepower (hp) liquid-ring vacuum pumps with much lower hp pumps, or even vacuum blowers with variable-frequency drives, cutting energy consumption by up to 50 per cent.

Designed for almost any application — from small profiles to the largest lineal profiles, or even fencing or siding profiles — the system will also allow extruders to use all their existing dry calibration tooling and form guides typically used in auxiliary tanks.

Additionally, the tooling can be spaced so as to maximize heat-transfer while minimizing warping, bowing or twisting. Existing form guides easily slide into mounting brackets in the cooling tank. The brackets are designed so that the form guides do not interfere with the high-intensity spray and thus they don’t affect the cooling of the profile. Finally, the tank can be built with multiple chambers, each with different vacuum levels and even different water temperatures.
