Removable access covers top and bottom provide for easy access to tubes without disturbing the piping.

Ease of cleaning with flue brush or water wash. Automatic water injection tube cleaning system available.

Securely attached tube permits replacing or plugging individual tube if required.

Two pass design permits convenient exhaust in the exhaust out of the top side of the vertical unit or in and out of same end of the horizontal unit. Exhaust inlet and outlet nozzles may be opposite one another or at 90 degrees from one another.

The vertical unit is supported on sturdy legs arranged to permit easy removal of bottom access cover.
