-Double Helical Coil Configuration: Three passes of flue gas along conservatively designed surface area.

-Base efficiencies can exceed 88% (LHV Basis), and with an optional economizer can exceed 93% (LHV basis).

-Flue gasses are significantly cooled eliminating the need for most internal shell insulation: Minimal long term maintenance concerns.

-Vertical Up-Fired, Vertical Down-Fired, or Horizontal Configurations

-Capacities available from 500,000 to 75MM Btu/hr.
