• Four-pass wet back design eliminates refractory baffles between flue gas passes.
• Minimum maintenance with rugged construction for extra-long life.
• U.L. listed packaged burner for firing gas, oil and combination gas/oil.
• Factory tested and checked for optimum operating efficiency.

• Durability
  Built in accordance with the ASME Code, the wet back design has proven to give much longer useful life cycles than dry back boilers.
  
  
• Quality
  Each unit is tested and inspected, and is registered with the National Board of Boiler and Pressure Vessel Inspectors.
  
  
• Design
  Hurst Boiler utilizes state of the art computer design techniques in every boiler. This accounts for accurate calculations of construction materials and optimum utilization of the boiler's performance criteria.
  
  
• Efficiency
  The Series 50W is designed for optimum fuel efficiency and has proven in certified tests to meet and often exceed the efficiencies of 4-pass boilers.
  
  
• Low Maintenance
  There is no refractory rear doors to maintain or replace. Elimination of these will result in thousands of dollars of savings.

• Tube Sheets
  The wet back has independent tube sheets with uniform temperatures. Four pass dry back boilers have tube sheets with large temperature variations and this results in premature tube failure and cracks in the tube sheets.
  
  
• Easy Access
  Since there is no large refractory rear door, one man can easily remove the rear cover plates for access to the tubes. Front doors can be opened without removing burner components or controls.
  
  
• Compact
  With computer aided design, Hurst has made the wet back a space saving workhorse without sacrificing the principle of 5 sq. ft. of heating surface per BHP.
  
  
• Combustion
  Dynamix uses name brand burner components with proven reliability. Every unit is boiler/burner compatible and tested at the factory prior to shipment
