Bayonet-Ultra Recuperators are high efficiency heat exchangers designed to fit into the exhaust leg of single, U, O, W or Trident-type radiant tubes. They’re frequently paired with Tube Firing burners and suitable for use with exhaust streams up to 2100 Degrees Fahrenheit provide fuel savings up to 30%. Conventional recuperators have only one heat transfer tube. Each Bayonet-Ultra contains multiple tubes to dramatically increase the heat transfer area while significantly decreasing the amount of fuel required to maintain required heat levels. Plus, an air cooled housing cools the work area.
