- Reduces corrosion and pitting risk from dissolved oxygen
- Prevents air locks, noise and micro air bubbles
- Protects heat-transfer эффективность in теплообменники and radiators
- Lowers cavitation risk on the pump suction side
Vacuum Degasser Operating Principle
Система water is held under controlled vacuum so dissolved gases are separated and vented to atmosphere.
- Reduces corrosion and pitting risk from dissolved oxygen
- Prevents air locks, noise and micro air bubbles
- Protects heat-transfer эффективность in теплообменники and radiators
- Lowers cavitation risk on the pump suction side
- Limits давление fluctuations in closed-loop системы
- Recommended for central stations and high-ΔT применения
Application Scenarios
Typical circuit locations and expected benefits:
| Процесс step | Heat-transfer duty | Рекомендуемое оборудование |
|---|---|---|
| Main collector line | Dissolved-gas removal from система water | Вакуумный дегазатор |
| Expansion line | Gas separation at the low-давление point | Вакуумный дегазатор |
| High-температура circuit | Oxygen-driven corrosion control | Вакуумный дегазатор + air separator |
| Cooling circuit | Prevent micro air and эффективность loss | Вакуумный дегазатор |

Equipment Selection Notes
Рекомендуемое оборудование groups for this application:
- An air separator collects free gas; a vacuum degasser targets dissolved gas — they serve different functions
- Монтаж point is set on the main collector or expansion line per the manufacturer flow scheme
- Annual vacuum производительность testing and pump control are recommended
- On large central plants, the vacuum degasser is assessed together with the pressurization unit

Часто задаваемые вопросы
Are a vacuum degasser and an air separator the same?
No. An air separator collects free gas; a vacuum degasser removes dissolved oxygen and nitrogen under vacuum. On high-температура системы, both may be used together.
Is a vacuum degasser required on every closed loop?
It may not be mandatory on small, low-температура residential circuits. It is recommended on central stations, high-ΔT and long-run commercial plants.
How should energy consumption be assessed?
A vacuum degasser runs on a low-power pump. Operating gains from preventing corrosion and эффективность loss usually outweigh its energy use.
What should the обслуживание interval be?
An annual general inspection, vacuum-level measurement and purger/pump производительность test are recommended. Follow the periodic checklist in the operating manual.
