With YANMAR, Reliability Comes Naturally

Our gas engines have been the core of our technology for more than 30 years, and installed in more than 300,000 CHP and VRF applications across the globe. Because the engines were developed from our already world-class diesel engine technology, they are designed to last with the longest maintenance interval in the industry at 10,000 hours for CHP.

Environmental Stewardship from Day 1

Well before green initiatives were mainstream, we were dedicated to developing environmentally-friendly products. Our passion for more earth-friendly technology started with our founder. Magokichi Yamaoka was committed to reducing fuel waste and creating products that could lead to a better world.

Reliable to the Core

YANMAR’s reliability stems from the core technologies that drive our systems. The primary component of the YANMAR CHP and VRF systems is our YANMAR-designed, lean-burn Miller Cycle Gas Engine. The lean-burn system optimizes ignition timing and matches the excess air intake, reducing NOx emissions and creating low fuel consumption.

For CHP, the engine adds to the unit’s operating efficiency by offering a 10,000 hour maintenance interval, which is the longest in the industry.

In VRF systems, the compressor is driven by natural gas instead of electricity. This leads to a 90% reduction in electric consumption for the total heat pump system. VRF also uses exhaust heat from the gas engine to maintain indoor comfort levels regardless of the outdoor temperature.

Strong Since 1912

Our strength comes in large part from being privately owned and family-run since 1912. This has provided a foundation that has helped us to remain focused on our vision, while growing our business across the globe. As we have expanded, we have invested in placing the right people in each market. We employ more than 16,000 people in more than 17 different countries with an even more expansive support and service network of distributors and dealers. Our current product offerings not only include Energy Systems, but also industrial diesel engines for off-road applications, marine diesel engines for pleasure and commercial applications, agricultural equipment and compact construction equipment.

Controlled from Design to Application

YANMAR products are engineered for specific applications. We have manufactured more than 250,000 gas engines for use in Energy Systems products and more than 15 million diesel engines ranging from 4.5 to 5,000 horsepower. In fact, more than 1 million YANMAR engines power some of North America’s leading-edge mobile and stationary off-highway equipment. We design critical components for engines together because components that are made together work better together. By controlling the process from design to manufacture to end application, we create greater efficiency and reliability.

Long Term Savings

Our efficiency and reliability gives our energy systems products some of the lowest lifecycle costs in the industry. When you consider the purchase price, maintenance costs, cost of operation and expected life of the product, there’s simply no comparison. Investing in YANMAR products pays off in the long term.

Green Procurement Guidelines

As restrictions on environmentally hazardous substances become stricter worldwide, YANMAR is continuing to act for the prohibition of hazardous substances from our products. And, as the growth of global procurement continues, these activities need to extend to YANMAR group companies all over the world. Thus, we ask our suppliers to follow the YANMAR Group Green Procurement Guideline regarding prohibited hazardous substances.

This guideline, the Third Edition from August 2010, specifies the prohibited use substances regulated by Japanese laws and international treaties (the previous guideline only described our intention and did not list the prohibited use substances).
