Oxygen barrier is the main function
The primary function of the EVOH layer is to block oxygen diffusion. EVOH prevents oxygen from passing through the pipe wall. This protects the system from oxygen-related corrosion. PEX-EVOH pipes EVOH layer is an oxygen barrier.
Corrosion prevention
Oxygen in water causes corrosion in metal components. Boilers, pumps, and radiators can rust and degrade. The EVOH layer stops oxygen from entering the water. PEX-EVOH pipe prevents corrosion of system components.
Protecting heating systems
Hydronic heating systems have many metal parts. Oxygen attacks these parts and creates sludge. The EVOH layer maintains water quality and system efficiency. PEX-EVOH pipe is essential for heating system longevity.
Extending system lifespan
Corrosion reduces the lifespan of heating systems. Boilers and pumps fail prematurely. The EVOH layer extends equipment life. PEX-EVOH pipe increases the overall system lifespan.
Maintaining water quality
Oxygen can also degrade water quality. It supports bacterial growth in the system. The EVOH layer keeps the water clean and pure. PEX-EVOH pipe maintains water quality for system operation.
Meeting German DIN standards
German standard DIN 4726 requires oxygen barriers for heating systems. Permeability must be below 0.1 mg/m²·day. PEX-EVOH pipe EVOH layer meets this standard.
Example: a residential boiler system
A home has a boiler and radiator heating system. PEX-EVOH pipe is used for the distribution pipes. The EVOH layer prevents oxygen from reaching the boiler. Example: the boiler lasts 25 years without corrosion.
Example: a commercial hydronic system
A large building uses a chilled water system. PEX-EVOH pipe carries the chilled water. The EVOH layer protects the chillers and pumps. Example: a long-lasting, efficient cooling system.
Chemical resistance of EVOH
EVOH is resistant to many chemicals. It resists acids, alkalis, and salts. This makes it suitable for various water conditions. PEX-EVOH pipe EVOH layer is chemically stable.
Durability of the EVOH layer
EVOH is a durable material when properly manufactured. It bonds well to the PEX layers. It remains effective for decades. PEX-EVOH pipe EVOH layer is designed for long-term use.
Limitations of EVOH
EVOH is sensitive to moisture and UV. It requires proper storage and handling. It can degrade under extreme conditions. PEX-EVOH pipe EVOH layer needs protection.
Final main function summary
The main function of the EVOH layer in PEX-EVOH pipe is oxygen barrier. It prevents oxygen from entering the water system. This protects metal components from corrosion. It extends system lifespan and maintains water quality. It meets DIN 4726 standards for oxygen barriers. The EVOH layer is chemically resistant and durable. It requires proper storage and handling. PEX-EVOH pipe EVOH layer is essential for heating and cooling systems. Example: a key component for system protection and longevity.
