The Company

AirGreen Inc. was reorganized as a Delaware C-Corp in November 2017 from AirGreen LLC. The company has its main offices and assembly facility in New Castle, Delaware.

AirGreen manufactures a novel and patented air conditioning and dehumidification system designed to provide superior comfort while also saving significant energy costs. Unlike traditional mechanical cooling systems, AirGreen uses a closed-loop liquid desiccant system to strip the moisture (humidity) from the air while also cooling it.

The AirGreen system has been designed to provide superior comfort at substantial lower operating costs. If humidity is an issue – this is where AirGreen’s performance really sets us apart. When compared to mechanical systems that overcool and reheat to control humidity, the AirGreen technology can save up to 60% in cooling season energy costs. And because we are providing comfort with much drier air, the actual A/C setpoint can be raised a few degrees with no loss in comfort. Finally, our liquid desiccant cooling system also scrubs the air of pollutants, pathogens, and microbes, improving air quality and reducing the chance of mold formation – which can occur frequently when moisture and humidity are not controlled.

The AirGreen technology improves the reliability, economy and efficiency
of any manufacturing or processing operation that is humidity-,
temperature- or microorganism-sensitive. We provide reliable, precise
and economical temperature and humidity control. Advantages include:

  • Reduced energy costs via simultaneous air cooling and dehumidification
  • Neutralization of airborne microorganisms and pathogens
  • Reduction or elimination of mold and bacteria
  • Improved ventilation via more energy-efficient treatment of outside air
  • Reduced refrigeration tonnage by eliminating costly sub cooling and reheat of process air
  • Improved product quality

The heart of our proprietary process is a patented multi-stage liquid desiccant system that can handle Latent Heat Ratios up to 100%. The products use both cold and hot water to provide sensible and latent cooling in summer and heating and humidification in winter. Enthalpy recovery from the exhaust airstream is approximately 85%. When used with a water-to-water heat pump both the cold and hot sides are produced at very high efficiency, where CoPs are typically 5.0 or higher on each side.

As compared to existing desiccant wheel dehumidification technologies, and other chemical dehumidification systems, AirGreen provides a cost-effective approach that is both reliable and efficient.

AirGreen installed and commissioned a number of initial commercial applications during 2019 and is launching its 3rd generation design in the 4th quarter of 2020. We plan to exhibit this break though technology at the forthcoming AHR/ASHRAE conference in Chicago in early 2021.

The AirGreen Vision

At AirGreen, we wish to do our part in combating climate change by providing engineered HVAC and dehumidification systems that do not add to the growing problem but provides a solution to it. Left unchecked, the expansion of traditional air conditioning systems in a warmer world will actually add to the climate issue, requiring significantly more greenhouse gases that are a traditional by-product of powering such systems.

We will deliver commercially competitive systems saving more than 50% of the energy costs of such traditional mechanical systems and will do it in such a way that scrubs the air of unwanted pathogens. We will provide custom systems for indoor growing applications to significantly lower the energy footprint of such facilities, facilities designed to solve future food supply needs.

All the AirGreen products are made in the USA.

The AirGreen Mission

It is AirGreen's mission to design, develop, manufacture, and deliver a new and innovative approach to HVAC equipment – one that provides significantly lower operating costs, is more environmentally friendly and sustainable, addresses significant shortfalls in treating humidity, and provides superior indoor air quality by allowing more outside (fresh) air while also killing various pathogens including bacteria, molds, and viruses.

Eric Holloway 
COO and Investor

Eric was born and raised in Wilmington, Delaware.  After attending AI DuPont High School, he went to Hamilton College and majored in Economics and minored in Literature.  Having worked every summer in the family industrial distribution business and having an interest in working in the industry, he went to Texas A&M University and proceeded to obtain a Bachelor’s of Science from the Industrial Technology Department in Industrial Distribution which is a mix of business and engineering curriculum.

After TAMU Eric joined Holloway Bros Tools Inc representing the third generation of the family to work in the business.  Five years later he bought out his father’s interest in the business and proceeded to grow it through acquisition over the next five years before selling beneficially to an industry consolidator, MSC Industrial Supply (NYSE: MSM).  Eric had a two-year contract to help integrate the business into MSC but quickly realized he enjoyed the entrepreneurial style of work.

He partnered in the purchase of Signature Systems, today renamed Signature Furniture Services.  That business spawned a couple of other businesses, Signature Construction Services LLC and Signature Executive Search LLC all of which Eric is the sole owner today and are managed by a Controller.

Eric has always had an interest in small business having been a member of YEO, Young Entrepreneur’s Organization, through his 30’s where he made many friends and contacts he is still close to 20 years later.

Eric is married to Monique Holloway and they have two children Ben and Dana.  Monique is a co-owner of a small investment advisory business. Ben works in San Francisco for a boutique private equity company and Dana is a junior at Hamilton College. Besides working, Eric has been a member of the Wilmington West Rotary Club for 25 years, 6 of which he was the Treasurer as well as President for a term.  He is a member of the Greenville Country Club and has served on the board in the capacity of Director of Facilities as well as President and is President again in November 2017. He serves on the Tatnall School Financial/Endowment Committee.

Brett Riley
Development Engineer

Brett Riley is a recent graduate of Temple University with a B.S. in Mechanical Engineering and concentration in Energy Systems. Fields of interest are renewable & alternative energy systems, HVAC design, and sustainable farming. He has had previous internship experience with a sustainable farming start-up based in Jerusalem, Israel where he helped to design aquaponics systems built out of recycled/repurposed material as an affordable means for families in lower income urban areas to be able to grow their own food.

Brett has also worked on a project to renovate a high tunnel greenhouse at a community garden near Temple University that grows fresh and affordable produce for the local community in North Philadelphia. His team installed a rainwater catchment system to decrease the dependence of municipal water, implemented a passive ventilation system to promote air circulation and better regulate the greenhouse environment, and installed a solar powered system to provide a source of electricity to power the necessary equipment the farm might require. The produce grown in this greenhouse, managed by Federation of Neighborhood Centers (FNC) a nonprofit organization focused on youth development and urban farming, provides fresh and affordable food to the local community that would normally not have access to. It has become a continuing Senior Design project for College of Engineering students at Temple University, and Brett continues to work with future groups to improve on the system and efficiency.
