Low Pressure Steam Boilers | Lathrop Trotter | Lathrop Trotter

Low Pressure Steam Boilers. Steam boiler technology is used for a wide range of applications. Many steam boiler systems require saturated steam, which means the water and the steam in the vessel must be at the same temperature. When this steam is 15 PSIG or below the boiler is considered low pressure as defined by ASME Section IV.

Steam Boilers - Rite Boilers If the required steam pressure/temperature

If the required steam pressure/temperature is 13psi/246° or less you are looking at a low-pressure boiler. Anything above this pressure/temperature requires a high-pressure steam boiler. The Rite Advantage - Our steam boilers are built with an integral superheater. Superheaters provide more energy per lb of steam compared to other designs.
