CHICAGO (July 28, 5:25 p.m. EDT) — At NPE, Universal Dynamics Inc. debuted a blender it is touting as more efficient, and a dryer that promotes safety.
The space-saving TSWB weigh blender has a loader mounted on top of it, as a single machine. Materials are vacuum loaded into the weigh hopper, where colorants and other materials are added through separate components. The resin then is dropped into the blender, project manager Till Menzel said.
"The beauty is you´re combining the loading with the blending," in a system that is less than 8 feet tall, added John Fleischer, vice president of sales and marketing.
The "plug and play" design allows manufacturers to wheel it over to a machine, plug it in and let it go, he said.
"As soon as a customer gets the weight they want, they don´t really have a whole lot of things to do," Fleischer said.
Also touted for its efficiency is the PCT2 series of twin-bed dryers.
Unlike previous Una-Dyn dryers, the PCT2 series is enclosed in a cabinet, better recirculating air through the closed-loop system so that it has no chance to escape.
The dryers have a capacity of 300-1,500 pounds per hour and can be be powered by gas or electricity, said Una-Dyn President Donald Rainville.
Though not a new product for Una-Dyn, the LS2 series vacuum chamber has been reintroduced with several design changes to promote safety.
The clamps on the top of the hopper now are oversized, to allow an employee to manuever them with one hand, Rainville said.
"In many cases they are standing up on a machine. We want them to have one hand free to hold on," he noted.
A single steel stand is connected to the mounting flange to allow the varied sizes of vacuum chambers to be removed and used interchangably, he said.
The chambers range in size from 0.75-6 cubic feet.
The new vacuum system will remain the same price as its predecessors, Rainville said.
