Hurst 500 Series

The Hurst 500 Series four-pass wetback scotch marine boiler is an ideal choice for all commercial and industrial applications when engineering mechanical systems using the latest HVACR technologies. The Hurst 500 Series boiler provides fuel efficiencies that exceed most four-pass designs. Having no large refractory rear door, these boilers allow one technician easy access to all tubes. The boiler front doors can be opened without removing any burner components or controls.

Standard Features

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 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 500 is designed for optimum fuel efficiency and has proven in certified tests to meet, and often exceed, the efficiencies of four-pass boilers.

Low Maintenance
There are no refractory baffles to replace or maintain. Elimination of these will result in thousands of dollars in savings.

Tube Sheets
The wet back has independent tube sheets with uniform temperatures. Three and 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 the 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
Hurst uses name brand burner components with proven reliability. Every unit is boiler/burner compatible and tested at the factory prior to shipment.
