Series 200
Two Pass Dry Back Packaged Scotch Boilers
Two and three-pass dry back scotch marine boiler. Two pass design eliminates
refractory baffles between flue gas passes. Minimum maintenance with rugged
construction for extra-long life. Efficiencies allow for burning number 5
and number 6 oil with complete combustion with low heat release.
Available in Steam or Hot Water Versions |
15 - 800 HP Pressures to 300 psig
