All our systems are built to deliver superior performance, significant energy conservation, and long-term savings.

Combined Heat and Power (CHP) Systems
Harness the power of a single system to meet your energy needs. Yanmar's Combined Heat and Power (CHP) systems use a clean, natural gas-powered engine to generate both electricity and heat simultaneously.
This advanced technology maximizes energy efficiency, allowing you to:
- Lower your utility bills by generating power on-site.
- Reduce your carbon footprint with a more environmentally friendly solution.
- Improve your energy independence with a reliable power source.
With Yanmar CHP, you get a smarter, more sustainable way to power your facility.
Gas Heat Pump (GHP) & VRF Technology
Experience a new level of heating and cooling with Yanmar's Gas Heat Pumps. These systems utilize a natural gas-powered engine and Variable Refrigerant Flow (VRF) technology to deliver precise temperature control.
Unlike traditional systems, our GHPs capture waste heat from the engine to boost efficiency, ensuring powerful heating performance even in colder temperatures.
With Yanmar, you get an energy-smart solution that provides superior comfort while significantly lowering your operational costs.
