Yanmar Unveils New Commercial Rooftop Unit Lineup: Setting a New Standard for Efficiency, Reliability, and Seamless Upgrades

Branford, CT, October 27, 2025 – Yanmar, a global leader in advanced industrial equipment and energy solutions, today announced the launch of a new line of Commercial Rooftop Units (RTUs). Rooted in a century of engineering excellence, the Yanmar RTU lineup is designed to maximize energy efficiency, ensure superior climate control, and dramatically simplify the unit replacement process for commercial and industrial facilities.

The new RTU line is engineered to provide facilities with exceptional operational performance and long-term cost savings, directly challenging the industry standard with robust construction and advanced control technologies.

Engineering Excellence Backed by Industry-Best Warranties

The Yanmar RTU is built with durability and longevity in mind, demonstrated by its best-in-class structural and warranty features:

• Industry-Leading Warranty: Each unit is backed by a robust 5-Year Parts Warranty and an unparalleled 25-Year Non-Prorated Heat Exchanger Warranty, offering unmatched protection for a critical component.
• Superior Efficiency: The Yanmar RTU boasts an impressive Integrated Energy Efficiency Ratio (IEER) of up to 21.3, significantly surpassing current industry standards and translating directly into lower operating costs.
• Built in the USA: Manufactured with meticulous quality control in the United States, the units feature durable double-wall, 20-gauge panels and are available with industry-leading short lead times, often as quick as 4 weeks for standard configurations.

Three Models to Meet Every Facility Need

The new RTU lineup is available in three primary models to provide flexible solutions for varying commercial requirements:

1. Standard Rooftop Unit: A high-efficiency packaged system (available in 5-50 tons) delivering robust, reliable heating and cooling for a wide range of applications.
2. Advanced Heat Pump with Dual-Fuel Capability: This innovative system (available in 5-30 tons) integrates an electric heat pump with natural gas auxiliary heat. It automatically selects the most economical fuel source based on outdoor conditions, ensuring maximum efficiency and cost savings year-round.
3. Dedicated Outdoor Air System (DOAS): A specialized solution (available in 3-60 tons) designed to condition 100% fresh outdoor air. The DOAS improves indoor air quality, manages humidity independently, and utilizes integrated energy recovery technologies for superior efficiency.

Simplifying the Upgrade Process

Recognizing the challenges of replacing outdated equipment, Yanmar has prioritized an effortless transition for facility managers and contractors:

"We built this RTU line not just for performance, but for the customer experience," said Eddie Caton, Manger Yanmar Energy Systems. "Our commitment to the simple, reliable swap is rooted in our innovative in-house curb adapters, which ensure a perfect fit for existing footprints. This feature, combined with our fast lead times and the industry’s best heat exchanger warranty, makes the Yanmar RTU a strategic investment in a building's efficiency and future value."

The Yanmar RTU line is ideally suited for facilities 1,500 square feet and above, including office buildings, retail centers, healthcare facilities, manufacturing plants, and educational institutions.
