HC Pressurisation and Degassing Automats

The Compact Unit with 5 Functions

For the smooth and long-term stable operation of a heating system, the factors of degassing and pressure maintenance are of utmost importance. The Olymp Pressurisation and Degassing Automat HC is the ideal solution for this. Free and dissolved gases, as well as air bubbles that enter the heating system during filling or through system components, are removed again using the unique ventilation process in the Heating Water Controller. 

5 Functions:

• Expansion: Compensates for the expansion of water.
• Automatic Pressure Maintenance: Ensures constant pressure within fixed limits.
• Refilling: Compensates for water losses (leakage-monitored).
• Degassing / Ventilation: Supports facility management.
• Sludge Removal: Achieved through relaxation in the storage tank.

How Does the HC Work?

1. Pressure Build-Up & Pressure Reduction

The “Pressure Build-Up” and “Pressure Reduction” functions of the Olymp Heating Water Controller HC are key components of efficient heating water regulation. The controller continuously monitors and adjusts the system pressure to ensure optimal heating system performance.

With precise sensors and automated control mechanisms, the HC ensures that the pressure remains within the ideal range at all times, maximizing heating efficiency and energy savings. Additionally, the HC protects the system from pressure fluctuations that could cause damage or operational disruptions.

2. Degassing

The degassing function plays a crucial role in ensuring the efficiency and longevity of the heating system. The HC removes dissolved gases, such as oxygen and nitrogen, from the heating water to prevent corrosion and air pockets in pipes and radiators. This process guarantees an even heat distribution throughout the system. The HC continuously monitors the degassing process automatically, ensuring smooth and reliable heating operation.

The principle behind it: When you open a bottle of sparkling water, you hear a “hiss” as gases escape. Simply put, the Pressurisation and Degassing Automat works on the same principle. It removes all aggressive and disruptive gases from the heating system – even from extremely unfavorable areas. The physical foundation of this process is based on Henry Dalton’s law.

3. Refilling

The refilling function ensures a constant and optimal water pressure within the heating system. As soon as a pressure drop is detected, the HC automatically regulates the refilling of heating water to restore the desired pressure.

This prevents performance losses and protects the system from damage caused by insufficient water pressure. The precise control mechanism also ensures efficient water resource management and contributes to the long-term operational reliability of the heating system.

4. Ionized Disinfection

The ionized disinfection function is an innovative water treatment technology that operates without chemical additives. Through ionization, germs, bacteria, and other microorganisms in the heating water are effectively reduced.

This environmentally friendly process enhances water quality and protects the heating system from contamination and deposits. The controller’s automatic regulation ensures continuous disinfection, contributing to an efficient, hygienic, and sustainable system operation.

The Olymp Automats are ideal for the following uses:

• All sealed heating and chilled water installations up to 120°C designed to EN12828
• Chilled water sytems with up to a 40% glycol content to -5°C
• Also available for degassing/deaeration without pressurisation and top up functions 
• Single or twin pump versions  

5 Good reasons to use the Olymp Automat

1. Small footprint multi function. Expansion – Automatic Pressure Maintenance – Top up -Degassing/Deaeration – Dirt removal – System Dosing
2. Injector at inlet. Lets gasses escape producing water poor in disolved gases (stripped) = „gas poor“ top up.
3. Maintenance free vessel. Long life – completely neutral to all system materials.
4. No intermediate vessel required. The use of high quality solenoid valves suitable for a high inlet temperature means that no intermediate vessel is required.
5. Long term stability. Industrial grade controls, sensors and solenoid valves keep the pressure constant year on year. Exceptional long life through continuous use during Summer and Winter cycles.
