The DeltaFlex and eVoFlex flexible watertube boilers are available with a low water content design to comply with some state or provincial laws for stationary engineers.
Ontario’s TSSA has certified this boiler that uses less than 75 imperial gallons of water in operation for up to 300 HP with the integrated economizer. This boiler offers the best fuel-to-steam efficiency and does not require operators.
These boilers can also be supplied with a circulating pump to comply with the coil type design and provide the same operator exclusion while offering higher efficiency and steam quality than a coil type boiler.
When firetube boilers are not the favoured type of boiler due to the stationery engineer’s regulation constraints, a flexible watertube boiler usually offers a much cheaper alternative.
Stationary engineers usually account for the second-highest boiler room operating costs, right after the fuel costs. Choosing the right type of boiler for your application is, therefore, very important.
