High-Pressure Mist Humidifier
A high-capacity adiabatic system that pressurizes treated water and atomizes it through precision anti-drip nozzles into an AHU or large controlled space.
- Fine High-Pressure Atomization
- Low-Energy Adiabatic Operation
- Anti-Drip Nozzle Manifold
- Integrated Water Treatment
Product Introduction
A stainless multistage pump raises treated water to high pressure and supplies a manifold of precision nozzles. Each orifice creates a fine mist that evaporates into the airstream, adding moisture while absorbing sensible heat. Filtration and reverse-osmosis pretreatment limit nozzle deposits, and staged nozzle banks or variable pump control match output to demand.
Key Features
Stainless pump, tubing and manifold resist continuous purified-water service.
Anti-drip nozzles close positively when pressure falls and reduce post-cycle wetting.
Integrated filtration and treatment protect small orifices from scale and suspended particles.
Customer Product Concerns
High-pressure systems require fine atomization, clean water and controlled staging so droplets evaporate before reaching surfaces.
Nozzle deposits change spray pattern and create large droplets.Fine filtration and low-mineral treated water protect the precision orifices.
Nozzles drip after the pump stops.Spring-loaded anti-drip valves close each nozzle below operating pressure.
Short duct length does not allow full mist absorption.Nozzle placement, droplet size and staged capacity are matched to airflow and available distance.
A fixed-output pump causes repeated on-off cycling.Variable-speed pressure control or staged nozzle zones follow the actual humidity demand.
Typical Applications
Large pharmaceutical cleanroomsElectronics manufacturing hallsData-center air handlersPrinting and paper productionIndustrial evaporative cooling and humidification
