The Cullet Preheater System (CPH) improves glass furnace energy efficiency by transferring waste heat to cullet prior to melting. 

Proven in continuous operation since 1995, the CPH has been installed in glass plants worldwide, helping to achieve some of the highest furnace efficiencies in the industry.

Drawing on over three decades of operational experience, the system is engineered to deliver longevity, reliability, and ease of maintenance — all within a compact, cost-effective footprint.
