Reduce heat stress and improve air quality with Schaefer’s uniquely designed circulation fans. These fans are engineered to produce greater air movement and superior cooling no matter the application. Also known as Horizontal Air Flow (HAF) fans, these fans move air in a coherent horizontal pattern, creating a gentle racetrack air flow pattern needed in greenhouses to maximize heat distribution and humidity control by mixing the air, from ceiling to floor. Mount models without OSHA guards 7 feet or higher. SchaeferVentilation.com

Schaefer slantwall exhaust fans flush-mount from the inside of the building and shed water and snow once they are installed. Designed for high air flow and high efficiency, and available in many sizes and configurations to meet application requirements, the fans ship to growers fully assembled with aluminum inlet shutters, self-adjusting belt tensioner (on belt-drive models), and galvanized outlet guard. Available with VFD compatible three-phase motors for increased energy efficiency and ventilation flexibility.

The Schaefer Wet Wall Evaporative Cooling System uses the natural cooling process of water evaporation in conjunction with Schaefer exhaust fans to provide up to 30°F of cooling for large volume buildings. The snap-together, no-leak PVC system, including supply line, spray line, and reservoir, is easy to install, operate, and maintain. Water that does not evaporate is recycled through the pads, so no water is wasted. The system comes with single- or multi-stage automatic controls and center-feed and end-feed water supply.

A 2-inch oversize blade design means more Cubic feet per minute (CFM) per watt and lower fan blade rpm for longer life. The fans are made from heavy-gauged, die-formed aluminum and have a deep spun orifice. Tubular bearing and motor supports are welded to the frame for strong construction. Quietaire.com

J&D’s Green Breeze HAF Fan assists in reducing winter heating costs by efficiently moving air throughout the greenhouse, creating a more uniform temperature. Its patented open front guard helps cut cleaning time and maintenance costs, so you are back to full operation in no time. jdmfg.com

The Typhoon Exhaust Fan has heavy-gauge galvanized housing that includes an aluminum shutter that fits tight to the frame for less vibration. This fan is designed for exceptional performance, low maintenance, and low operating costs.

J&D’s ES Shutter Fan can be used indoors or outdoors and offers great performance. The totally enclosed UL507 outdoor-certified, energy-efficient motor is quiet and maintenance free, with sealed ball bearings. It is pre-wired for a No Electrician Required operation.

The PTP features a stainless steel tubular heat exchanger as standard on all units with a 10-year heat exchanger warranty, providing growers with peace of mind. Users of the PTP will also benefit from a design that allows for quick and easy installations. Modine.com

The Modine Effinity with BMS monitoring system offers unprecedented temperature control. By using a simple and inexpensive room sensor, Modine customers have functions of a BMS thermostat with the added benefit of equipment alarms and statuses that would not be available using a conventional BMS thermostat method. Modine’s board supports the energy saver function, which destratifies warm ceiling air temperatures before turning on the burners.

BioTherm’s Toob Oxygen Infuser and associated products provide a robust solution for increased dissolved oxygen levels in irrigation water. Systems start with flow rates as low as 2 gallons per minute and are able to scale as high as required. Infusion products can be installed in any type of system and are designed to increase levels of dissolved oxygen, providing a broad spectrum of plant health benefits. BioThermSolutions.com

Growers can maximize heating efficiency with a pre-engineered, custom Hydronic heat system from Stuppy. The system heats the soil at the root zone with rubber tubing radiant heat for even control of soil temperature. Hydronic bench heat promotes a higher seed germination rate, accelerated rooting in young plants, and faster plant growth, which leads to quicker crop turnover, better plant quality, less disease, and more economical heating costs. Get direct contact from tubing to root zone for maximum soil and plant temperature control. EPDM rubber tubing resists high temperatures and chemicals, offering superior heat transfer capabilities. The tube design creates different temperature zones for flexible growing, and reduces water volume, allowing the system to respond quickly and efficiently. Manifolds custom designed for each system are guaranteed not to leak, and tubing spacers are cut to bench width for ease of installation and optimum design spacing. Stuppy.com
