Expansion vessel Reflex N 600 for central heating, 6 bar / 120°C, grey

Reflex N 600 is an expansion vessel designed for closed central heating systems with a nominal volume of 600 liters. Constructed from steel and finished in grey, the vessel is built to manage thermal expansion and pressure fluctuations within heating circuits. It is rated for operation up to 6 bar and temperatures up to 120°C, making it suitable for residential and light commercial boiler systems, buffer tanks and similar installations where reliable pressure compensation is required.

Advantages

The Reflex N 600 offers a large working volume to reduce cycling and pressure variations in heating systems. Its steel construction provides mechanical strength and durability under repetitive thermal loading. Rated for 6 bar and 120°C, the vessel supports typical central heating conditions and contributes to system stability by accommodating fluid expansion. The neutral grey finish is suitable for plantroom environments and integrates easily with existing equipment.

Suitable for

• Residential central heating systems with larger heat yields
• Light commercial boiler rooms and small apartment blocks
• Buffer tank installations and thermal storage systems
• Closed-loop hydronic heating circuits requiring pressure compensation

Key specifications

• Nominal volume: 600 liters
• Maximum operating pressure: 6 bar
• Maximum operating temperature: 120°C
• Material: steel vessel with protective finish (grey)
• Application: closed central heating and buffer systems

How to use

Install the Reflex N 600 in accordance with applicable national regulations and manufacturer installation practices for expansion vessels. Position the vessel on a stable base or mounting support adjacent to the boiler or buffer tank, ensuring accessible connections for system piping, pressure gauge and safety devices. Pre-charge the vessel to the recommended air pressure for the specific system (typically matched to system static pressure), and verify tightness and correct operation during initial system filling and commissioning. Regularly inspect for corrosion, mechanical damage and correct pre-charge pressure as part of routine maintenance.

Usage recommendations

Ensure pre-charge pressure is set by a qualified technician before commissioning and rechecked during maintenance. Use appropriate safety valves and pressure-limiting devices in the heating circuit. If system parameters exceed the listed maximum pressure or temperature, select an expansion vessel with higher ratings.
