Mestek Inc. is proud to announce a strategic partnership with BioTherm, a leading provider of greenhouse climate solutions, to bring Sterling HVAC and RBI products to greenhouses, indoor farms, and controlled agricultural environments. This collaboration combines over a century of HVAC and horticultural expertise to deliver comprehensive, energy-efficient climate systems that help growers cultivate healthy, thriving plants.

With energy consumption being one of the largest operational costs in commercial and institutional greenhouse markets, BioTherm’s packaged hydronic heating systems are designed to maximize efficiency and minimize expenses. At the heart of these systems are RBI’s high-efficiency boilers and water heaters, which provide hydronic heating, irrigation tempering, CO₂ enrichment, and support for AC and dehumidification systems. Their compact design allows for seamless integration into existing facilities, even those with limited space, while delivering precise temperature control and reduced operating costs.

Complementing root zone heating, Sterling HVAC’s Agricultural Series unit heaters maintain ambient warmth for complete climate control. Engineered to perform in the most demanding agricultural conditions, Sterling’s unit heaters feature corrosion-resistant ZM coated steel cabinets and high-quality stainless-steel components, including tubular heat exchangers, in-shot burners, and flue collectors, for superior durability and heat transfer efficiency. A totally enclosed motor protects internal components from dust, humidity, and debris, ensuring long-lasting performance.

“We are thrilled to be a part of this exciting partnership to provide best-in-class technology for the greenhouse growing industry,” said Chuck Perry, vice president of sales and marketing at Sterling HVAC. “Sterling’s advanced technology is built to withstand the harshest environments while delivering reliable, efficient heat.”

“Working with Mestek’s family of brands means growers can source everything they need for efficient greenhouse heating under one roof,” said Jim Rearden, president of BioTherm. “The combination of high-performance boilers and unit heaters provides unmatched reliability and climate control, and we’re proud to integrate that technology into our engineered climate systems.”

This partnership underscores Mestek’s commitment to innovation and sustainability in agricultural HVAC solutions, offering growers a trusted, all-in-one source for advanced climate control.
