Spirotech Steel Deaeration Units
Every system is susceptible to the problems associated with air. Automatic Air valves are very limited in their ability to remove air from the system because they can only remove air that is local to it and only when the system is in a static (non circulating) condition. The Spirovent Deaeration unit is considered the industry leader as it is extremely fast in separating both Free air (large bubbles) and Dissolved air (microbubbles) from the circuit even when operating at flow rates up to 3 mtrs/sec.
Beyond this the unit harnesses “Henry’s Law of Physics” (the absorption of gasses in a fluid) to ensure the system remains air free for life.
These passive units Require no maintenance and with no power consumption, they provide the contractor with the fastest possible commissioning times and the end user with a system that operates at optimum efficiency and protection against ongoing air related and corrosion issues.
Available versions:
• Standard flow steel Units (designed for a nominal flow velocity up to 1.5 m/s)
• Hi-Flow Unit(designed for a nominal flow velocity up to 3 m/s)

Benefits:
• Fast and efficient removal of air from system.
• Fastest possible commissioning of circuits – Repeatable gauge readings, no chasing of air around the system.
• Permanent air free system (including dissolved oxygen).
• No cavitation of circulating pumps
• Silent operation of system, no cascading of air at system high points
• No more bleeding of radiators or other circuits.
• Other units available for a complete range of sizes, pressures and temperatures.
