    Corner Tube Boilers

    The ERK (corner tube) Boiler is a modern, natural-circulation, single drum water tube boiler. The main characteristics are a very active water circulation, rapid load change capability, light-weight construction and self-supporting structure.

    Fire Tube Boilers

    Fire tube boilers are the backbone of low pressure steam and hot water applications. The flue gases pass through the furnace and various smoke tubes. Typically, such boilers provide saturated steam or hot water. However, superheated steam supply is possible. With ERK Tubes such boilers can be very compact and low cost.

    Bi-drum Boilers

    Bi-drum boilers are well-known and widely established systems. Typically, operating in natural circulation to provide saturated or superheated steam. ERK does provide bi-drum boiler designs but has adapted the standard version with an advanced water circulation to improve operational performance and reliability.

    Special Boilers

    Some applications require special boiler or heater systems. ERK has designed many special boilers and heater to meet particular demands, such as heating of chemicals or simultaneous supply of steam and hot water. Special systems can be designed in natural or forced circulation, with multiple fuels, and for multiple working fluids.

    Marine Boilers

    Marine boilers have to cope with the various ship movements without losing operational performance. ERK marine boilers are ideal for such applications as the design is self-supporting and has a very stable water circulation. The natural water circulation minimises auxiliary power consumption.
