Typical Applications for Continuous Systems

  • Annealing
  • Hardening
  • Preheat
  • Normalizing
  • Stress Relieving

Benefits of Continuous Operation

  • Batch systems require constant heating and cooling.  This wastes energy and stresses materials
  • Batch material handling is difficult to automate
  • Energy recuperation is easier and less costly with continuous systems
  • Continuous takes up about half of the floor space than multiple batch units
  • Longer equipment life – typically 40+ years

Designed to Meet Your Needs

  • Temperature ranges from 4000F – 22500F (2000C – 1,2000C)
  • Suitable for atmospheres from air or products of combustion to exothermic (EXOGAS™), Endothermic (ENDOGAS™), Nitrogen/Hydrogen or Ammonia (AMMOGAS™) or steam
  • Throughputs are unlimited but typically from 500 pounds (225 kg) to 15,000 pounds (6,800 kg) per hour
