Wittmann Inc.´s CoolMax portable chillers incorporate dual pumps for maximum flow rates, one for process and the other for recirculation between the tank and evaporator.
In other chillers, according to Wittmann, the flow rate is restricted by the evaporator, but CoolMax´s dual-pump design provides independent circuits for maximum flow rate in each one. The chiller also can cool the tank without running the water to the process.
In other product news, Wittmann´s compact Drymax Dual PDC dries and conveys resin to a single drying hopper, and sends material to one or two injection presses. The integrated drying and conveying cell costs about 12 percent more than a single drying unit and cuts total floor space by 25 percent compared with two single units.
In robot news, Wittmann introduced the W 711 C DS robot designed for quick removal of parts from stack molds and two-plate, single-face molds. Mechanically, the robot is based on the platform of the W 711 series with a fixed kick-stroke frame. However, unlike standard robots in the series, this model has a second, fully independent vertical axis, driven by servo drives.
Wittmann, of Torrington, Conn., also has added higher temperature capabilities to its Basic line of mold temperature controllers, with the Basic 300.
