Pelletron offering its latest dedusters
Pelletron Corp., which makes equipment for removing dust, fines and fluff from resin pellets, introduced the XP-series of dedusters.
Pelletron cut the height of the deduster in half, reducing the space needed for installation. The design also doubled the area of the cleaning decks, to boost throughput, and cut air consumption by improving the air distribution setup.
New integrated air boosters provide accurate flow control. A newly designed venturi zone minimizes the carry-over.
The company from Lancaster, Pa., also introduced a new family of its Pellbow elbow shapes to streamline movement of pneumatically conveyed resin and cut dust and streamers as it speeds along. Pelletron enlarged the bend at the incoming side to produce a soft layer of pallets just before they impact the angled part.
Pelletron also introduced a new ball-type diverter valve for powders and pellets. A modular design means the valve can be changed to flow angles of 45, 90 and 135 degrees.

TowerKlean enhances water management
TowerKlean LLC of Waterford, Mich., debuted a new concept in industrial water management, called the TK2.
A new reaction vessel, with a conical design, gives four times the capacity of previous TowerKlean columns, with a smaller footprint. Other new features include:
* The unit now includes an onboard conductivity controller.
* The system can grow by adding additional reaction media, and adjusting the flow. A single vessel can treat from 1,800-7,200 gallons.
*A pivoting reaction vessel allows for quicker and easier maintenance when performing the annual change of media.

Gneuss touts latest filtration systems
Filtration equipment maker Gneuss Inc. showed the new generation of the RSFgenius, and the new rotary model of the SFXmagnus.
Improvements to the RSFgenius include a faster purging time, so a complete color or material change can happen within three to 10 minutes. Other advances are the operator's ability to monitor melt quality and the reduction of energy consumption by 35 percent.
Gneuss developed the rotary SFXmagnus for applications that do not require an integrated screen changing.
Gneuss, of Matthews, N.C., also debuted a compact viscosimeter for on-line measurement of melt viscosity. The instrument is fitted between two flange connections. Using a metering-gear pump, a small amount of the melt is diverted from the main melt channel, through a precisely manufactured slot capillary.

Ritemp highlighting mold-cooling system
Australian firm Ritemp Technologies Pty. Ltd. introduced a way to cool a mold efficiently and uniformly by creating a vacuum, so the cooling water can boil at very low temperatures.
The heat is transferred directly to the water, and the boiling water cools the mold. The water will always boil where it is hottest and condense where it is coolest - so the temperature profile throughout the mold gets evened out automatically. There are minimal variations in temperature across the mold surfaces.
The vapor rises to the top of the mold, where it is condensed by simple heat exchangers.
Ritemp, based in Edwardstown, claims its licensees have cut cycle time by 20-50 percent. The firm said that maintaining efficient, uniform control of mold surface temperatures during mold cooling is a major challenge facing the plastics industry.
When water boils at very low temperatures, the water can absorb heat at an enormous rate. Since it is only necessary for water to contact the target surface for this to happen, there is no need for high-velocity, forced-flow water circuits.
Most areas of the mold can be accessed by the coolant, regardless of mold complexity. Ritemp officials said multiple circuits are not normally needed, but they are easy to balance if they are required.
