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.
Frequently Asked Questions
What is the Neptronic SKH4 humidifier?
The Neptronic SKH4 is an atomizing high-pressure humidifier designed for commercial, industrial, and specialized HVAC applications requiring efficient humidification, evaporative cooling, or precise climate control.
How does the SKH4 high-pressure humidifier work?
The SKH4 pumps water at approximately 1,000 psi / 70 bar through precision nozzles to create an ultra-fine mist that evaporates into the air through adiabatic cooling.
What capacity range does the SKH4 offer?
The SKH4 provides high-capacity output from approximately 210 to 2,800 lb/h, or 100 to 1,250 L/h, with strong turndown for varying humidity loads.
Why choose the SKH4 instead of a steam humidifier?
The SKH4 uses adiabatic evaporation, which consumes less energy than steam humidification and can also provide evaporative cooling in suitable HVAC applications.
Can the SKH4 serve multiple zones?
Yes. The SKH4 can support up to 4 zones per pump station using stage valves and remote valve panels for flexible humidity control.
Where can the SKH4 nozzles be installed?
SKH4 nozzles can be installed directly in the space or inside ducts. Fan-assisted mist distributors can also be used to improve mist distribution and humidity uniformity.
Awarded for innovation
The SKH4 humidifier was honored as “Humidity Control Product of the Year” in the UK in 2025
