Description

The cooling furnaces consist of furnace modules that have a standard length of 2.25m. Pennekamp has incorporated other proven details into the furnace design to increase the performance as well as the productivity of the furnaces while reducing energy consumption.

Features

  • Band widths up to 5.5m
  • Gas or electric heating
  • Heated zones with inner hoods as well as circulation fans and belt grates made of heat-resistant stainless steel
  • Entrance door made of stainless steel
  • Gas heating system with compact burners and all safety devices
  • Electric heating system based on thyristor control
  • Furnace completely insulated up to the cold end (approx. 300mm mineral wool)
  • Circulating fan with direct shaft, no V-belts (maintenance free)
  • Automatically controlled air intake dampers in the rapid cooling zones, i.e. in case of production stop direct reaction of the furnace to maintain the set temperature curve
  • Automatic control and regulation of the furnace temperature
  • Electronic control system for automatic optimization of air movements (drift) inside the furnace to reduce consumption (supply and exhaust air dampers)
  • Special fan wheels at the cold end for mixing the cold air with the air inside the furnace before contact with the glassware
  • Optimal temperature distribution over the furnace belt width
  • Easily adjustable belt run adjustment at the furnace belt drive
  • Optional additional cooling system at the furnace outlet
  • Communication link to the charging system
  • Conveyor return inside the furnace with self-cleaning effect
  • Adjustable tunnel exit temperatures, important for cold end tempering
