Hermetic & Custom Designs

Hermetic & Custom Designs
 
The Spencer Engineering Edge is indispensable when you are faced with handling flammable, explosive, unstable, toxic or hazardous gases and are not able to change the process that requires or produces them. Hermetic and custom blowers and gas boosters can be built to handle methane-rich landfill and digester gases, flue and stack gases, radioactive waste gases, acid fumes, etc. Maximum parameters include temperatures to 1100°F, housing design pressures to 1000 PSIG, operating pressures to 300 PSIG.
 
Spencer® Gas Booster and Special Blowers Catalog
 
We create cost-effective designs that meet your needs in the most sensible way. For example, if you have a process generating corrosive gases or fumes that might destroy a carbon steel or cast iron blower, we may offer special coatings for components in the gas stream or special materials of construction such as 316L stainless steel to deliver more blower longevity.
 

Nuclear industry experience

Spencer made the first gas boosters approved for use in nuclear breeder reactors. Our special high-pressure gas boosters with hermetically welded seams and internal electric motor are virtually leak-free; shaft seals are not required. We have lengthy experience with nuclear power plant blowers and gas boosters for component cooling, process ventilating, off-gas systems and LOCA (Loss of Coolant Accident) systems. 
 
Spencer is a trusted vendor for the most critical air and gas handling applications in the world. Some examples:
 
Hermetic Gas Boosters
 
Hermetic Gas Boosters
Hermetic construction can be supplied where the gas composition and temperature are compatible with available motors (the explosion-proof motor is encased by the blower housing, where it is cooled by flowing process gas). Electrical connections are made through a terminal box on the outside of the housing. Leakage rate can be as low as 10-9cc/sec.

Other Specials
Digester Gas and Landfill Gas Booster Skid Packages
Digester Gas and Landfill Gas Booster Skid Packages
These custom, packaged systems contain gas boosters, controls and other equipment for handling methane-rich gases from organic decomposition in anaerobic wastewater digesters and municipal landfills. Instead of seeing them as only “nuisance byproducts,” informed operators are recovering these flammable gases as valuable alternate fuels for boilers, gas turbines, sludge heaters and fuel cells.
 
A companion Spencer product is the Natural Gas Dilution System, which compensates for variations in the supply of digester gas or landfill gas by adding natural gas to ensure a steady energy supply.
