ULS Series – High-Efficiency Shell Boiler

ULS Series steam boilers are robust, high-efficiency three-pass shell boilers designed for saturated or superheated steam generation in commercial and industrial settings. With output ranges from 1 250 to 28 000 kg/h and pressures up to 30 bar, they offer exceptional versatility and thermal efficiency up to 95.5%, with even higher recovery when combined with an integrated economiser or condensing heat exchanger. The design features large water volumes for stable load response, low NOₓ burner compatibility, and seamless integration with intelligent control systems. Suitable for use with gas, oil, biogas, hydrogen, or hybrid fuel systems, the ULS Series delivers sustainable steam performance with a compact footprint and low operating cost.
