Propane Systems

Blender Compressors

Types: Propane-air and natural gas-air

Power: Electric, propane or natural gas

Typical uses/applications: Mission-critical, life-safety and healthcare facilities that require an on-site redundant fuel source and facilities with natural gas curtailments agreements.

Propane-air is an effective back-up fuel for high-efficiency, natural gas fired boilers. Propane-air can also be used to continue operation of other appliances including kitchens, independent space heating equipment, domestic water heaters, etc.

Natural gas-air is an excellent back-up fuel for low heat content bio-gas applications such as anaerobic digesters and landfill gas. The natural gas can be blended with air to match the properties of the biogas to supplement periods of reduced production.

Capacity/pressure: Systems can be engineered to meet a wide variety of capacity and pressure requirements Fuel types: Propane, natural gas


Types: Liquid propane (LPG), ammonia vaporizers

Power: Electric for control and vaporization in smaller systems. Electric for control and propane for vaporization in larger units.

Typical uses/applications: Remote facilities not served by natural gas infrastructure. Used in conjunction with a mixer for back-up and redundant fuel in larger facilities. Also used in selective catalytic reduction (SCR) applications

Capacity/pressure: Systems can be engineered to meet a wide variety of capacity and pressure requirements.

Fuel types: Propane, natural gas (NG), compressed natural gas (CNG), liquefied natural gas (LNG)

During periods of high demand, natural gas utilities inject propane-air mix into the distribution system to meet capacity requirements, a process known as “peak shaving.”
