- Furnace construction utilizes a welded-membrane wall design.
- Large, water-cooled, gas-tight furnace areas.
- Boiler wall constructions are 100% water-cooled and refractory-free.
- Only single-source supplier for integrated boiler, burner, and control solutions.
- High power in a slim fit.
- Can accommodate selective catalytic reduction (SCR) and CO catalyst.
The O-type design features a water-cooled furnace and an evaporator section with a low gas-side pressure drop that reduces fan power consumption. The vertical gas outlet minimizes the width of the overall package and allows for large steam capacities in restrictive footprints. This rugged design has become the true workhorse of the rental boiler industry. Its symmetrical design is ideally suited for mounting on a trailer for over-the-road transport. Cleaver-Brooks line of rental units continues to provide efficient and reliable service year after year, while withstanding rapid emergency startups.
