HVAC Solutions Engineered Around Your Facility

Tesla Gigafactory 1 is a lithium-ion battery and electric vehicle subassembly factory near Reno, Nevada. The facility supplies battery packs for Tesla electric vehicles and stationary storage systems and is located at the Tahoe Reno Industrial Center in Storey County.

Manufacturing batteries is highly energy intensive, and the equipment throughout the factory generates significant heat, making dependable cooling essential. Tesla required a manufacturer capable of providing custom air-handling solutions with the flexibility to accommodate detailed project requirements while remaining cost effective. Tesla turned to Dunham-Bush because of its ability to provide flexible, custom features at an economical price point.

Dunham-Bush teamed up with Tesla to design the cooling system for the factory. In the factory's 2B area, Dunham-Bush installed 44 air handlers, ranging from 5,000 to 7,500 CFM, in a vertical configuration with stainless interior liners, a custom top diffuser section, and 4-inch final filters.

Tesla also required hot spot cooling, so Dunham-Bush supplied three 10,000 CFM air handlers with explosion-proof construction in a vertical configuration.

The project also called for CCL units, and Dunham-Bush installed two 45TR air-cooled ACPSJ DX packaged units with VFD scroll compressors for cooling only, direct-drive plenum fans, supply and return fan control from 0-100%, economizer control, and 12-inch final filters after the supply fan.

The project was commissioned by Dunham-Bush in March 2018. Tesla was extremely pleased with the efficiency, reliability, and ease of use of the units, as well as the cost effectiveness the project provided for the factory.

The Yacht Club at Portofino is a 34-story luxury high-rise residential building located in South Beach, Miami, Florida, featuring 361 residences and premium shared amenity spaces. To maintain year-round comfort throughout the building's common areas, the property required a high-performance HVAC solution capable of conditioning 100% outside air while operating reliably in South Florida's harsh coastal environment.

South Florida's climate is hot and humid, making air conditioning necessary year-round. Because the Yacht Club at Portofino is located very close to the ocean, the equipment also needed to withstand highly corrosive coastal air. The building required a unit capable of cooling 100% outside air for common areas including hallways and the lobby. Because the project was a retrofit with limited access conditions, the unit also had to be delivered completely knocked down for assembly at the job site.

Dunham-Bush USA partnered with Debonair Mechanical to provide a customized water-cooled packaged solution for the building.

The unit featured 316 stainless steel construction for extreme corrosion protection, along with coils protected by a 10,000-hour ASTM B-rated corrosion coating. Modulating hot gas reheat technology was incorporated to provide precise humidity control.

Because of the retrofit installation requirements, the unit was supplied in knocked-down construction and assembled on site by Debonair Mechanical and Dunham-Bush before commissioning.

The completed installation delivered reliable year-round cooling, enhanced humidity control, and long-term corrosion resistance in South Florida's demanding coastal environment. Knocked-down construction and on-site assembly also reduced installation complexity and allowed the end user to avoid the costly expense of a crane.

11190 Biscayne Center is an eight-story commercial office building located in Miami, Florida, with a total built-up area of 131,445 square feet. The building serves tenants that demand high-quality comfort cooling and indoor air quality.

When the building owner decided it was time to replace the existing 29-year-old water-cooled chiller, they turned to Dunham-Bush and their local representative for an energy-conscious solution. The existing chiller was outdated, consumed a significant amount of energy, and was costly to maintain. When the time came to retrofit the chiller plant, the owner relied on the Dunham-Bush team to provide an energy-saving solution capable of meeting the building's cooling requirements.

Dunham-Bush supplied a high-efficiency water-cooled magnetic bearing oil-free centrifugal chiller, model DCLC230MD.

The chiller was designed with multiple compressors and a common refrigerant system to provide reliable, high-efficiency operation. The DCLC-M magnetic bearing oil-free centrifugal chiller series is capable of Integrated Part Load Value performance in the low 0.30 range while also providing quiet operation, with overall sound ratings averaging approximately 65-68 dB(A).

Since the magnetic bearing chiller was placed into operation, the system has delivered over 40% savings in monthly energy consumption while providing precise control of the building requirements.

The combination of reliable operation, energy efficiency, and quiet performance made the magnetic bearing chiller a strong fit for the needs of 11190 Biscayne Center.

The Ohio Veterans Home in Sandusky is a 427-bed nursing home facility. The home opened in 1888 to care for veterans of the Civil War and has remained in continuous operation since. The facility is located near Lake Erie in Sandusky, Ohio.

At approximately 650,000 square feet, the Ohio Veterans Home required a cooling system capable of keeping up with the demands of a large facility. The organization wanted a more efficient and cost-effective solution that could provide dependable cooling while remaining easy to operate and maintain.

Dunham-Bush teamed up with the Ohio Veterans Home to design the cooling systems for the facility.

Dunham-Bush installed one DCLC-M300 300-ton magnetic bearing chiller along with air handling units. The DCLC-M magnetic bearing chiller was selected to provide a highly efficient cooling solution that is easy to use and maintain.

The new system provided a much more efficient cooling solution for the facility. The Ohio Veterans Home was extremely pleased with the efficiency, reliability, and ease of use of the units, as well as the cost-effective nature of the new equipment.

Hill Air Force Base is a major U.S. Air Force base located in northern Utah, approximately 30 miles north of Salt Lake City. The base is home to the Air Force Materiel Command's Ogden Air Logistics Complex, which manages a wide range of aircraft, engines, missiles, software, avionics, and accessory components.

Hill Air Force Base needed to reduce energy use while operating in a desert location that experiences extreme temperatures during both the summer and winter months. The base required a cooling solution with a proven track record for reliability that could handle substantial seasonal temperature swings while remaining cost effective to operate and maintain.

Dunham-Bush teamed up with Hill Air Force Base to design the cooling system for the base.

Multiple Zeus Series ACDS air-cooled scroll chillers were installed to keep up with the extreme temperature swings experienced during the summer and winter. The units incorporated multiple scroll compressors, environmentally sound HFC-410A refrigerant, high-efficiency plate heat exchangers, and Micro Vision controls.

The result was a more efficient cooling system designed to be easy to use and maintain at a cost-effective price.

The project was commissioned by Dunham-Bush in January 2019. Hill Air Force Base was extremely pleased with the efficiency, reliability, and ease of use of the units.

The base was also very pleased with the cost effectiveness of the project given the extreme nature of its location.
