Mojave Energy Systems has announced a $19 million Series B funding round intended to scale production of its ArctiDry platform as commercial buildings make humidity control a deliberate priority. The announcement was made on September 23, 2026 from the company's headquarters in Sunnyvale, California. Demand is growing across grocery, industrial, healthcare, hospitality, education, and other sectors where humidity performance is becoming essential.
Funding Details and Investor Participation
The Series B round was led by new investor Fairtree Elevant Ventures and included a significant investment from River Bay Investments. Returning investors At One Ventures, Fifth Wall, Myriad Venture Partners, and Starshot Capital also participated, while Cleo Capital and MetaTrail joined as new backers. This expanded investor group supports Mojave's mission to redefine humidity control and improve energy efficiency in commercial buildings.
Strategic Use of Capital
Mojave will use the new funding to grow its sales organization, expand manufacturing capacity, and accelerate development of new products on the ArctiDry platform. The company says these investments will help bring its humidity-first climate systems to more buildings faster. The capital is designed to meet increasing demand from facility teams that need reliable humidity management, lower energy consumption, and healthier indoor conditions.
ArctiDry Technology Platform
Mojave's patented ArctiDry DX unit is a liquid desiccant air conditioner that controls humidity and temperature independently, often serving as a Dedicated Outdoor Air System. The company introduced ArctiDry Hydro in 2026 for buildings that already operate chilled-water plants. This hydronic system uses conventional chilled-water temperatures to deliver supply-air dew points as low as 25 degrees Fahrenheit and improves overall plant efficiency by up to 20 percent.
Energy Savings and Operational Impact
Customers using ArctiDry report 30 to 60 percent lower energy use than standard HVAC systems, with typical payback periods under 18 months. Installations are expanding across the United States as building owners prioritize humidity performance alongside cooling. The platform is being adopted in grocery, healthcare, hospitality, education, and industrial facilities where indoor conditions directly affect operations.
Investor and Executive Perspectives
Chief Executive Officer Phil Farese said demand for Mojave products continues to increase because customers are done treating humidity as a side effect of cooling. David Evans, managing director at Fairtree Elevant Ventures, described the company as having the team and technology to transform the sector. Tom Leonard, CEO of River Bay Investments, added that his firm is already introducing Mojave to contacts in grocery, data centers, hospitality, and schools.
Company Background
Mojave Energy Systems is focused on humidity performance, which it defines as the intentional design, control, and continuous verification of humidity conditions a building needs. The company's ArctiDry platform includes its first two products, ArctiDry DX and ArctiDry Hydro, with a commitment to expanding the line across a wider range of buildings and climate systems.

With $19 million in new capital, Mojave Energy Systems is positioned to expand its ArctiDry product line and accelerate adoption of humidity-first climate technology.

Continued product development and strong investor support may help reshape how commercial buildings approach air conditioning and dehumidification.
