Vertical rental boilers are popular for steam users needing smaller requirements of steam and do not have much space available. This type unit is used very often by customers who need a small amount of steam to keep storage tanks warm during outages when their steam source is not available. These units can be fired on natural gas, propane and some can fire number 2 fuel oil. We offer up to 60 HP and 150 psi steam design pressure in this style of boiler. Skid mounted vertical boilers include the feed water system, pumps, a blow down separator and stack.
