Leadership Comments

“We’re thankful for the strong support from existing and new investors during this exciting phase of the business,” said Phil Farese, CEO of Mojave Energy Systems. “Demand for our products continues to increase because customers in grocery, industrial, hospitality, education, and other sectors are done treating humidity as a side effect of cooling.

“We back ambitious teams harnessing breakthrough innovation to redefine the future,” said David Evans, managing director at Fairtree Elevant Ventures. “Mojave has turned years of engineering work on liquid desiccant technology into equipment that building facility teams are rapidly putting to use, unlocking energy savings, superior humidity performance, healthier buildings, and reduced building carbon footprints.

Market and Business Growth

Mojave says customers using its ArctiDry systems report 30% to 60% lower energy use compared with standard HVAC systems, with typical payback periods of less than 18 months.

Its ArctiDry Hydro system can deliver supply-air dew points as low as 25°F and improve overall chilled-water plant efficiency by up to 20%.

The company is expanding ArctiDry installations across the U.S. as commercial building owners adopt its technology.

What Happens Next?

Mojave plans to expand its sales and manufacturing operations while continuing to develop new products on the ArctiDry platform.

The company aims to extend its humidity-first approach across a wider range of commercial buildings and climate systems.
