Rodon Beats the Heat with 'Green' Cooling Towers
Custom molder The Rodon Group recently upgraded its plant in Hatfield, Pa., with three new cooling towers that replaced units that had been in service for 25 years. The three towers have 240 tons of capacity and were installed during the plant shutdown for the July 4 holiday weekend. The move allowed Rodon (rodongroup.com) to increase its cooling capacity within the same footprint as the previous towers. In keeping with the facility’s commitment to “green” practices, the new towers were also designed to reduce water loss and power usage, and the old towers were recycled. The new units are made of non-corroding fiberglass/plastic composite.
“Through the hottest summer in recent memory, the new towers have maintained a remarkably consistent water temperature,” says Lowell Allen, sr. vp of manufacturing. “Our cooling capacity was increased by 40%, while cutting the energy consumption in half. We won’t know how much less water we are consuming for a few months, though we expect to reduce water usage by 20% or more. All of this while requiring almost no maintenance.”
The cooling system was furnished by Thermal Care, Niles, Ill.
A plastics molding plant runs on more than electricity—it runs on water.
For most injection molding jobs, cooling is 95% of the cycle time.
In the injection molding process, tool temperature is an important factor in achieving high-quality parts.
