About the company
Controlled Environments Inc., doing business as Conviron, is a for-profit small business manufacturer headquartered in Pembina, North Dakota, registered with SAM.gov since August 2, 2001. The company specializes in the design, manufacture, and installation of specialized plant growth chambers, environmental control systems, and related equipment for agricultural research, biotechnology, and life sciences applications. Conviron supplies advanced controlled environment systems to federal agencies that require precise climate control capabilities for critical research initiatives across the United States.
Conviron has established a substantial federal contracting presence across multiple federal agencies, demonstrating particular strength with the U.S. Department of Agriculture's Agricultural Research Service, which has awarded the company numerous contracts spanning various regional areas including the Pacific West Area, Northeast Area, Plains Area, Southeast Area, and Midwest Area. The company has also secured significant awards from the Food and Drug Administration for growth chambers supporting the Center for Food Safety and Applied Nutrition, the National Institute of Standards and Technology for specialized environmental and curing chambers, and the Department of Health and Human Services. Conviron's prime federal contract portfolio includes the delivery of numerous plant growth chamber models, including the PGC-FLEX, Model GR144, Model E8, Model E7/2, and Model GR128, as well as walk-in growth chambers, dual-compartment chambers, and LED greenhouse lighting systems. The company frequently provides comprehensive packages that include delivery, installation, training, warranty coverage, and preventative maintenance services. Notable recent awards include a $258,565 National Institute of Standards and Technology contract in December 2025 for environmental and curing chambers supporting additive construction research, and a $222,407 USDA award for a three-tier plant growth chamber with advanced controls. Conviron has received numerous small business set-aside designations throughout its contracting history, though it has also competed and won unrestricted and sole-source procurements.
