Humidification and Cooling Systems

HART provides unique and high-quality humidification products and systems to agricultural/farming, food, and other environmental industries. We address state-of-the-art improvements for hard to solve applications.

Our products include Ultimix™ and AirSaver™ atomizing spray nozzles, SoniQuench® evaporative gas cooling and conditioning of hot process gases, fogging systems for fruiting and grow rooms, and fugitive dust control. HART also designs the HEI (High Energy Ionizer) wet electrostatic precipitator for fine particulate emissions control.

Replacement and retrofit capabilities have provided clients with more reliable components, improved performance, and savings in operating costs.

In connection with our humidification and cooling systems, we have developed more improved spray nozzle designs. These spray nozzles improvements are to the existing inventions and designed to provide finer fogging quality, greater flow range, energy savings, and more robust construction for wear resistance.

The ULTIMIX™ and AIRSAVER™ designs provide flexibility in operating conditions by adjusting the air and liquid pressures and flow rates to maximize your application. These adjustments allow you to create a desired spray pattern to meet your requirements. HART spray nozzles are very user friendly and essentially self-cleaning due to the atomizing air pressure. Our nozzles produce sub-micron size droplets which evaporate before wetting walls and/or product.

For evaporative hot gas cooling applications, the nozzle assemblies can be equipped with a shielded cover to reduce possible abrasion from industrial dirty gas flows.

Another item we offer is our non-drip water valve for humidification applications such as farming/agricultural growing rooms where wetting is not desired on floors or product.
