AFRISO AAV 300, G1 1/4"

The AFRISO AAV 300 anti-freeze valve is designed to provide reliable frost protection for heating and cooling systems, particularly those using air source monoblock heat pumps. This valve is essential for preventing damage caused by freezing, ensuring the longevity and efficiency of your system. Here's why the AAV 300 is a crucial component for your installation:

• Robust Brass Body: Constructed from high-quality brass (CW617N) for durability and resistance to corrosion.
• G1 1/4" Connection: Features a G1 1/4" connection size, making it compatible with standard piping systems.
• High Flow Coefficient: Offers a Kvs value of 70 m³/h, ensuring efficient flow and effective frost protection.
• Precise Opening Temperature: Opens at 3°C (± 1°C) to prevent freezing, and closes at 4°C (± 1°C) to conserve energy.
• Integrated Vacuum Breaker: Prevents vacuum formation, enhancing the valve's performance and reliability.
• Mounting Valve Included: Simplifies the replacement of the thermostatic element without the need to drain the heating circuit.
• Maintenance-Free Design: Requires no regular maintenance, reducing the overall operational burden.
• Special Outlet Shape: Reduces surface tension to prevent water droplets from sticking and blocking the outlet.
• Wide Operating Temperature Range: Suitable for medium temperatures between 0°C and 70°C, and ambient temperatures from -30°C to +60°C.
• Versatile Medium Compatibility: Can be used with water or a mixture of water and glycol (up to 50% concentration).
• Effective Frost Protection: Protects against frost damage in the event of malfunctions or power outages.
• Avoids Costly Damage: Helps prevent significant damage to system components, saving on repair costs.

The AFRISO AAV 300 anti-freeze valve is engineered to safeguard your heating and cooling systems from the detrimental effects of freezing temperatures. With its durable construction, precise temperature control, and easy maintenance, this valve ensures reliable and efficient operation. Installation of the AAV 300 on the return and supply pipes near the outdoor unit provides essential protection, making it an indispensable addition to your heat pump system.
