DHT series

The sterilizing tunnels of the DHT series dry, sterilize and depyrogenize glass containers using a low-turbulence vertical air flow. The sterilizing-grade filters or integrated high-efficiency particulate air filters (HEPA filters) do not require any sealing on the air discharge side. Special hot gas filters in the sterilization zone produce a cleanroom class A atmosphere in all operating conditions (even during the pre-heating and cooling phases). The tunnels have multiple insulation layers to prevent heat loss and maximize energy efficiency.

Energy efficiency

Energy saving is also a top priority at B+S.
  • The sterilization process offers the greatest potential for reducing line energy consumption.
  • Multilayer insulation is used to minimize heat loss in the tunnel tube.
  • The pressure cascade is optimized to minimize the heat loss resulting from cross-flow between zones.
  • Air is recirculated within the sterilization zone, eliminating the need for an external air supply and maximizing energy efficiency.
  • Thanks to these and various other measures, B+S consistently achieves exceptional energy efficiency, setting the benchmark in the market.
