High-Pressure Atomizing Humidifier for Commercial and Industrial applications
High-Pressure Atomizing Humidification Technology
The Neptronic SKH4 is a high-performance atomizing high-pressure humidifier designed to deliver efficient, precise, and hygienic humidification across industrial, commercial, and specialized environments. By pumping water at 1,000 psi (≈ 70 bar) through precision nozzles, the SKH4 generates an ultra-fine mist (7-35 µm droplets) that evaporates through adiabatic cooling (extracting heat from the surrounding air).
With output capacities ranging from 210 to 2,800 lb/h (≈ 100 to 1,250 L/h) and a high turndown ratio approaching 20 lb/h (≈ 10 L/h), the SKH4 provides wide flexibility across load conditions.
Whether your goal is humidification, evaporative cooling, or precise climate control, the SKH4 stands out as an energy-efficient, low-maintenance solution.
What makes the SKH4 the right choice for large HVAC systems?
High humidification at low power
Because the SKH4 uses adiabatic evaporation, it consumes minimal energy compared to isothermal or compressed-air methods.
Broad capacity range & high turndown
Its modulation can scale from 20 lb/h up to full output, allowing fine control over various demands.
Low maintenance, hygienic design
Stainless-steel, water-lubricated pump option and anti-drip nozzles reduce clogging and maintenance overhead.
Flexible zone control
Up to 4 zones per pump station with stage valves and remote valve panels.
Smart integrated controller
The SKH4’s controller offers a menu-driven LCD interface, user role levels, quick configuration, and scheduling.
Versatile distribution options
Nozzles may be placed directly in space or in ducts. Use fan-assisted mist distributors (MDU / ADU) to maximize homogeneity.
Awarded for innovation
The SKH4 humidifier was honored as “Humidity Control Product of the Year” in the UK in 2025
