How It Works
Understanding the complete filtration and protection cycle
Water Circulation & Initial Filtration
Water circulates through the HVAC system, carrying heat or coolness to different zones. Magnetic filters capture ferrous particles (iron, steel) that can cause wear and damage to pumps, valves, and heat exchangers. These powerful magnets remove even microscopic metal particles before they can cause damage.
Air & Dirt Separation
Air and dirt separators remove non-magnetic particles, air bubbles, and sediment from the system. Air separators extract dissolved gases and air bubbles, while dirt separators capture sediment and debris. This prevents blockages, reduces corrosion, improves heat transfer efficiency, and eliminates system noise.
Flow Balancing & Control
Balancing and control valves ensure proper flow distribution throughout the system. They enable precise system balancing, maintain consistent flow rates regardless of pressure variations, and optimize energy efficiency by ensuring each zone receives the correct flow rate.
Water Treatment & Pressure Management
Chemical dosing systems introduce treatment chemicals to maintain water quality and prevent corrosion. Expansion tanks accommodate thermal expansion of water, maintaining proper system pressure and preventing overpressure conditions. Automatic air vents continuously remove trapped air to maintain optimal system performance.
System Protection & Clean Circulation
Safety relief valves monitor system conditions and automatically respond to overpressure or excessive temperature, preventing damage to expensive equipment. Clean, filtered, and properly balanced water continues circulating through the system, ensuring optimal heat transfer, reduced energy consumption, and extended equipment lifespan.
System Components
Each component plays a crucial role in system protection and efficiency
Magnetic Filters
Magnetic filters use powerful magnets to capture ferrous particles from the water system. They protect pumps, heat exchangers, and other critical components from wear and damage. RBM magnetic filters are designed for both residential and commercial applications.
Air & Dirt Separators & Hydraulic Separators
Air and dirt separators remove air bubbles, dissolved gases, non-magnetic particles, sediment, and debris from the water system. They prevent blockages, reduce corrosion, improve heat transfer efficiency, and protect sensitive components. These separators ensure optimal system performance and longevity.
