InSpire Transpiration Solutions Advances Energy Efficiency in Cannabis Cultivation with Sustainable Dehumidification System

InSpire Transpiration Solutions, an HVAC products and services provider in the controlled environment horticulture industry, is leading energy efficiency efforts in the cannabis cultivation space. The company has incorporated innovative sustainable dehumidification technology into its HVAC system designs. InSpire's patent-pending technology can help cultivators reduce heating, ventilation and air conditioning (HVAC) operating expenditures by as much as 30 to 50 percent. InSpire's Chief Technology Officer, Robbie Batts, presented on this technology and other best practices in HVAC on a panel last week at the Resource Innovation Institute's Indoor Agriculture Energy Solutions Conference

"Cannabis cultivation is an extremely energy intensive process, with primary energy demands coming from lighting and HVAC systems," said Adrian Giovenco, CEO of InSpire Transpiration Solutions. "Energy efficiency and sustainability are becoming increasingly important to cannabis businesses looking toward the future. At InSpire, our goal is to help our clients maximize profits and plan for future growth. Our holistic facility design approach coupled with our sustainable dehumidification technology has resulted in substantial energy savings for our clients - while driving product quality and maximizing biomass and chemotype expression."

Most commercial HVAC systems rely exclusively on a compressor, driven by an electric motor, to pressurize gas, exchange energy and reduce the temperature and humidity of the air in a given space. InSpire's sustainable dehumidification systems involve the use of a patent-pending multi coil water runaround loop to efficiently transfer energy before and after compressor-based dehumidification. The multi coil system reduces energy use and increases energy efficiency in two main ways:

  • Pre-Cooling: Cools the temperature of return air from the grow room to at or near the dew point prior to being dehumidified, without compressor energy
  • Free Reheat: Heats the temperature of the air after dehumidification without compressor or other new energy to bring it back to the grow room set point

This innovative technology allows cultivators to achieve superior environmental control with less compressor tonnage, resulting in substantial HVAC energy savings of up to 50 percent. InSpire executes additional efficient system design practices, such as targeted CO2 enrichment, microclimate mitigation via canopy airflow optimization, and cloud-based room control.

The 13 MP autofocus camera uEye XC is especially easy to operate and delivers high-resolution images and videos in the blink of an eye. Unlike typical webcams, it has been specifically designed for use in industrial applications and delivers sharp image data even in changing light conditions. Setting up and operating only requires a cable connection. The webcam-like camera is characterised by its particularly elegant and lightweight magnesium housing: with dimensions of only 32 x 61 x 19 mm, it is compact, sturdy despite its light weight and absolutely suitable for industrial use - benefiting, for example, kiosk systems, applications in industrial production or agriculture. With the uEye XC Starter Set, IDS offers a full-package deal for $500. (launch promotion, valid until 30 November 2022) that allows customers to evaluate and use the full range of functions of the new camera. The set includes not only the camera, tripod adapter and cable, but also a macro lens. Thanks to this lens, the camera is also suitable for demanding applications at close range. It easily shortens the minimum possible object distance and opens up additional application possibilities.
