AQUA-FILTER
Marvel Ventilation presents Aqua Fill, an advanced water management solution designed to optimize the performance, reliability, and efficiency of HVACR systems. Aqua Fill provides precise control over water levels, reduces waste, and maintains consistent system pressure, enhancing equipment longevity and operational efficiency. Ideal for commercial and industrial applications, Aqua Fill simplifies maintenance, improves energy efficiency, and supports environmentally responsible operation. Its innovative design ensures dependable performance, making it a trusted solution for professionals seeking reliable and efficient water management in HVACR systems.
Construction Details
The Aqua Fill wet-scrubber is fully constructed from high-grade stainless steel (SS-304) and features multiple water nozzles along with dual baffle-type filters to retain water droplets. This design ensures effective grease filtration, efficient fire protection, and significant reduction of exhaust gas temperature. The interior of the unit is accessible from both sides for easy cleaning or filter replacement.
The water nozzles produce an adjustable spray that covers the entire gas flow area. Each nozzle is removable for cleaning and includes an inner filter to remove water impurities, achieving maximum cleaning efficiency with minimal water usage. The specially designed casing minimizes external condensation and reduces dripping to a minimum. An integrated control box featuring a manometer, pressure-reducing valve, and electrically operated solenoid valve ensures the system operates in sync with the fan, maintaining optimal water pressure at the nozzles for consistent performance.
Operating principles:
Water is sprayed in fine droplets to achieve five fundamental effects:
- To create jets of water to sweep away drops of grease and other air-born solid particles, to the collector tray.
- Even when there is no sweeping effect, the drops of grease grow on contact with the water droplets and are caught more easily in the filters.
- Condensation of grease and oil which go from a gaseous to a liquid state as a consequence of the sprayed water’s undergoing an adiabatic change of state.
- Dissolution of soluble compounds, principally aromatic compounds, in the drops which will later be trapped by the filters.
- Extinguishing sparks.

How water spraying affects the temperature:
The first effect we achieve by spraying water is to increase the contact area between water and air. To understand this just imagine that an amount of water is composed of drops together.
Of all those only the upper part of those on the surface are in contact with the air. When we spray what we do is separate them, which brings the total surface area of each drop into contact with the air. Thanks to this effect, what we achieve is, on the one hand to sweep a large area effectively and, on the other, facilitate the adiabatic change of state through which, with no input of heat, and without reaching its evaporation point, the water passes to a gaseous state with the consequent absorption of heat and drop in temperature.
The higher the temperature and the lower the moisture content of the fumes, the greater the drop in temperature will be. In ideal conditions, it is possible to achieve drops in temperature of tens of degrees
For example, if the air in the kitchen is at 20ºC and the relative humidity is 50% and the fan is extracting the fumes from a barbecue at 75ºC, the drop in temperature would be more than 50º C, giving a final temperature of about 25ºC.
(In practice we shouldn’t expect such spectacular drops in temperature as it difficult to achieve a complete transformation).
