Series 200

Two 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

• Two-pass design eliminates refractory baffles between flue gas passes.
