Delivering a Turnkey Energy Efficient HVAC Solution for Yanmar Warehouses
When a world-class equipment manufacturer needs to upgrade their own facilities, they need a partner who can manage the job from the structural engineering down to the final software programming.
We are proud to announce the successful completion of a massive HVAC integration for the Yanmar Tractor and Parts Warehouses. For this project, Controlled Air served as the lead organizer and turnkey provider, delivering a seamless “design-to-execution” experience that modernized the climate control for two massive industrial spaces.
Here is a look behind the scenes at how Controlled Air managed this complex infrastructure project.
The Scope: Total Project Management
This was not a simple “swap and drop” equipment changeout. This was a comprehensive facility upgrade.
Beyond the mechanical installation, our team managed the critical logistics to keep the project running smoothly:
- Structural & Architectural: We handled the structural reviews and the installation of pre-engineered deck support systems to safely hold the new heavy-duty equipment.
- Roofing & Rigging: From crane rentals and rigging to the necessary roofing repairs and curb installations, we ensured the building envelope remained secure.
- Utilities & Safety: We managed the complete gas piping infrastructure, electrical connections, and fire alarm tie-ins (including duct smoke detectors).
The Technology: High-Efficiency Synergy
One of the most exciting aspects of this project was the equipment selection. We paired high-performance air handling with Yanmar’s own cutting-edge engine technology.
To condition this massive space, we furnished and installed a robust system designed for longevity and efficiency:
- Air Handling: Seven (7) Aaon 30-ton Rooftop AHUs, fully equipped with VFD blowers for energy efficiency and a high-grade filtration system using MERV 8 and MERV 13 filters.
- Heating & Cooling: These units are powered by fourteen (14) Yanmar 14-ton Gas Heat Pumps (GHP). This 2-pipe natural gas system utilizes Yanmar’s engine technology to provide efficient heating and cooling with reduced electrical demand.
- Reliability: The system includes custom 14″ roof curbs, stainless steel drain pans, and vibration isolation to ensure quiet, long-term operation.
2. The Parts Warehouse
Similar to the tractor facility, the parts warehouse received a top-tier upgrade:
- Three (3) Aaon 30-ton Rooftop AHUs paired with six (6) Yanmar 14-ton GHPs.
- This setup ensures that valuable inventory is kept at consistent temperatures while maintaining high air quality standards through double-wall cabinets and advanced filtration.
Intelligent Controls
Controlled Air furnished and installed a complete Johnson Controls ecosystem to tie the entire facility together.
We deployed panel-mounted controllers across both warehouses, complete with all necessary sensors, relays, and current switches. For the Parts Warehouse, we installed a Johnson Controls Supervisory front-end controller. This web-based user interface allows facility managers to monitor the system remotely, ensuring peak performance and immediate diagnostics.
The Controlled Air Difference
By handling everything from the certified air balancing and start-up testing to the permits and gas meter coordination, Controlled Air ensured that Yanmar could focus on their business while we handled their building.
We are thrilled to hand over a facility that is energy-efficient, structurally sound, and controlled by the latest in building automation technology.
