SpiroVent Superior S600
High-Capacity Vacuum Degasser SpiroVent Superior S600 is a fully automatic, high-performance vacuum degasser designed for closed heating, cooling, and process water systems. It is particularly suited for large installations where mechanical air separators are insufficient or where systems have significant static height. How It Works The S600 operates by applying vacuum degassing. A portion of […]
What Is Vacuum Degassing?
Vacuum degassing exposes system water to very low pressure, significantly below atmospheric pressure, causing dissolved gases to be released.
Water naturally absorbs gases until it reaches saturation. The saturation level depends on pressure and temperature: at lower pressure, less gas can remain dissolved. SpiroVent Superior processes system fluid in small, controlled volumes and subjects it to vacuum pressure, releasing the dissolved gases – similar to opening a carbonated beverage bottle.
The degassed liquid is returned to the system. This ‘gas-hungry’ liquid absorbs air pockets present in the system and carries them back to the unit for removal.
Why Choose Vacuum Degassing?
In complex systems, it is often impossible to predict where air will accumulate. In such cases, vacuum degassing provides a system-wide solution, eliminating air even in locations where gas release is difficult to anticipate.
Air in the system reduces energy efficiency and causes corrosion, noise, circulation problems, and increased maintenance. Traditional air separators remove free air bubbles but cannot eliminate dissolved gases.
Smart Control and Installation
Modern SpiroVent Superior models feature a clear display and remote control capabilities (S400 and S600 include Modbus as standard). The interface provides real-time system status and alerts for refilling needs.
Product Selection
The most important selection criteria are system fluid and operating pressure:
- Water / 40% water-glycol / 40% water-ethanol (0…+90°C):
- S400 (1–4 bar), S600 (2.5–6 bar), S10A (5–10 bar), S16A (9–16 bar)
- Options: -R (automatic refill unit), -I (insulated)
- Water (+15…+70°C): S250 (0.5–2.5 bar)
Ensure system reliability and energy efficiency – choose SpiroVent Superior, a leading solution in vacuum degassing.

Key Benefits of SpiroVent Superior:
- Lower energy consumption: Air-free systems transfer heat and cooling more efficiently.
- Reduced maintenance costs: Prevents corrosion and sludge formation, extending the lifetime of pumps, valves, and heat exchangers.
- Silent operation: Eliminates noise such as gurgling and flow disturbances.
- Fast commissioning: Accelerates filling and venting of new systems.
- Fully automatic operation: Continuous monitoring and automatic degassing.
Typical Applications
- Residential and commercial buildings
- District heating networks
- Cooling systems (chillers)
- Underfloor heating systems
Additional Advantages:
- Removes all gases: free air, microbubbles, and dissolved gases
- Degassed liquid absorbs and removes trapped air pockets
- Energy-efficient operation with extremely low residual gas content

Placement and Operation
Because vacuum degassers remove dissolved gases through pressure reduction, their placement is less critical than traditional air separators. They are particularly suitable for systems:
- with multiple branches and low flow velocities
- with small temperature differences
- where inline air separation devices cannot be installed
- where gas release locations cannot be predicted
- with very low local flow velocities
