Wittmann touting its dual-pump chillers
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.

K-Tron introduces latest SmartConnex
K-Tron Process Group introduced the next generation of its SmartConnex feeder controls, the KCM, or K-Tron Control Module.
The KCM integrates the control and motor drive modules directly on the feeder, in a single, compact, new housing.
It can function as either a volumetric or gravimetric feeder control, supporting all K-Tron feeders equipped with the SFT II or SFT III load cells. It readily connects directly to any factory programmable logic controller.
In other news from K-Tron, based in Pitman, N.J., the company has expanded its Bulk Solids Pump feeder line by adding two models, both available in volumetric and gravimetric versions.
The BSP-135 feeders can be configured using a platform scale, three-point or one-point suspension weighing. The BSP-150-P can be configured as a loss-in-weight feeder using three-point suspension weighing.
BSP feeders do not use the usual screws or augers, belts or vibratory trays to convey material. Instead, they use positive displacement action to feed the materials.

Franklin Miller offers twin-shaft shredder
Franklin Miller Inc.'s Taskmaster Titan twin-shaft shredder uses an innovation to handle jobs that normally require shredders that use two to three times the power and cost thousands of dollars more.
The design uses two counter-rotating shafts, but its intermeshing cutter stacks have two different diameters. One is much larger than the other. The result: a high-capacity shredder with a large inlet opening size and large shredding chamber that does more with less power.
The cutting chamber ranges in size from 14 inches by 16 inches to 14 inches by 60 inches.
A sensor detects jam conditions and automatically reverses the shredder to clear the obstruction.
Franklin Miller is based in Livingston, N.J.
