L & R Refrigeration: Increase energy efficiency in plastics processing with modern refrigeration technology
System for cooling of plastic machines - (Image: L & R Refrigeration).
The L & R Refrigeration GmbH & Co. wants to use the Fakuma 2012 to plastics processors demonstrate a not often used possibility of increasing efficiency. Modern refrigeration technology can reduce energy requirements for injection molding, but also in other processes such as extrusion, calendering, blow molding and finishing thus much.
Besides the generation of compressed air is the refrigeration of the largest single energy consumer in plastics processing. Companies that rely on continuous improvement of its efficiency, will find opportunities to reduce costs and also to improve their CO2 footprint.
As a specialist in industrial refrigeration wants L & R show at Fakuma 2012, the plastics industry, how to achieve this goal can be. Shown is a "typical" refrigeration system, which comes in an injection molding for use and equipped with energy-saving design features is. This variable speed compressors, pumps and fans are as much as a sliding "Vari-Kon" condensation control and a sophisticated electronic "Frigo Control" controller which controls the system as needed.
Proves to be very effective in practice, therefore, a winter relief. Then an additional free cooler is known that at low temperatures using the ambient cold for cooling and thus relieves the refrigeration and with it the energy cost budget.
Since these measures can achieve at a reasonable cost by rebuilding and upgrading of existing facilities, the user does not have to buy a completely new system in order to reduce the cooling-related energy costs.
It is crucial from the perspective of L & R that the optimization of refrigeration is not associated with impairment of quality and productivity. The opposite is true: A modernized cooling system could result in the plastics processing industry often means that the temperature-controlled processes are regulated precisely. This creates the conditions for faster cycle times and increased productivity. The user benefit is twice when he uses modern refrigeration systems: due to energy savings and increased yield.
