The Neptronic SKD Direct Steam Injection Humidifier is engineered to provide precise, high-capacity humidification in commercial and industrial HVAC applications by injecting clean, low-pressure steam from an on-site boiler directly into the airstream. Custom designed to meet specific steam capacities and non-wetting distance requirements, the SKD integrates with various steam distribution configurations — including jacketed tubes and Multi-Steam™ dispersal systems — to ensure uniform moisture addition with minimal condensate carryover.

Equipped with the SKDESC electronic steam controller, the SKD modulates steam delivery based on real-time humidity demand and steam quality, optimizing performance while reducing energy waste. Optional technologies like high-efficiency insulated distributors and patent-pending pressurized condensate return (PCR) provide enhanced heat transfer efficiency and drain-free operation. Designed for integration with BACnet or Modbus networks, the SKD is ideal for demanding environments such as hospitals, laboratories, airports, museums, and other facilities with stringent humidity control requirements.
