The rapid growth of the Indoor Agriculture industry and its Controlled Environment Agriculture (CEA) facilities, demand a precise and complicated set of HVAC design requirements. Essentially, all HVAC systems that meet these design requirements would fall under the category of custom. As a result, significant risks for operators remain with: scalability; high CapEx; and high OpEx. Harvest Air is a patent pending system that leverages proven technology and is designed specifically for use in CEA facilities. Harvest Air provides value to operators in three key categories: 1. The lowest total cost among qualified systems: Initial CapEx reductions of ~25% and up to 75% reductions in annual OpEx. 2. Improved scalability and increased speed to market: Factory built and tested, with a production capacity of 100 units per month. 3. Unrivalled control of your production environment Zero transfer of outside air to the cultivation environment, and a completely packaged and factory tested control system. At the heart of the patent pending Harvest Air design is the HarvestWheel; a total energy wheel used for indirect air-to-air economization. Indirect air-to-air economization is the use of outside air to cool and dehumidify the cultivation space, without bringing the outside air into the space. The production capabilities behind the Harvest Air units extend to complete supply chain ownership by centralizing the wheel manufacturing, and complete unit controls integration, under one roof. The result is a completely packaged and factory-tested system that ships and installs as a single piece.
