Energy Source: Hot water (waste heat or boiler loop)
Function: Converts available hot water into cooling, making it perfect for facilities with waste heat recovery or dedicated hot water sources.
Capacity Range: 422 kW – 9,305 kW
Key Benefit: Great choice for heat recovery, cogeneration, or facilities with industrial hot water streams.
Energy Source: Direct-fire heat (e.g., gas burner)
Function: Uses direct flame-generated heat to drive the absorption cooling cycle — ideal where fuel heat is available without an intermediate loop.
Capacity Range: 528 kW – 7,034 kW
Key Benefit: Efficient cooling without external steam or hot water systems; perfect for plants with fuel-based heat sources.
Energy Source: Steam (from boiler or cogeneration)
Function: Uses steam heat to drive the absorption process — excellent for industrial sites or campuses with steam infrastructure.
Capacity Range: 528 kW – 11,631 kW
Key Benefit: Best for large-scale cooling where steam is abundant, such as manufacturing plants or utilities.
Energy Source: Exhaust heat + hot water
Function: Flexible dual-source system that can use either exhaust gas heat or hot water to power the chiller, maximizing available thermal energy.
Capacity Range: 528 kW – 7,034 kW
Key Benefit: Versatile solution for facilities that generate both exhaust heat and hot water — boosting overall energy efficiency.
