Shop used, surplus and secondhand gas generators from IPP – in stock and engineered for chemical, pharmaceutical and utility operations

Save on infrastructure costs with IPP’s ready-to-ship gas generators for backup power, process heat and energy resilience

Used gas generators provide flexible, efficient energy production using natural gas, propane, syngas or biogas. Whether supplying backup power, reducing electricity dependence, or generating process heat, gas generators are key assets for facilities requiring continuous and controlled energy sources. With more than 47 years of expertise, IPP delivers used, secondhand and surplus gas generators from 20 complete plant sites and a massive inventory of 15,000+ systems that are ready for rapid deployment.

IPP’s offerings include skid-mounted units, combined heat and power (CHP) systems, and engine-driven generators from top brands like Caterpillar, GE, Waukesha, Siemens and Jenbacher.

Primary uses across industries

• In chemical and pharmaceutical plants, for process gas generation or emergency power backup
• In utilities and municipal systems, for grid support and peak shaving
• In manufacturing and refining, for CHP integration and facility-wide energy efficiency
• In food, beverage and agri-processing, for low-emission onsite energy and thermal drying

Types of materials processed or consumed

• Natural gas and propane for fuel
• Biogas and syngas from anaerobic digestion or waste-to-energy operations
• Process gases integrated with scrubbers or dryers for heat recovery

Common materials of construction

Industrial gas generators are engineered for continuous-duty use and environmental resilience:

• Steel skid frames for portability and protection
• Stainless steel components for corrosion and heat resistance
• Explosion-proof enclosures for hazardous area compliance

Key features of gas generator systems

• Continuous or standby operation with auto-start controls
