## Long description

Reflex V 40 l is a 40‑litre expansion and cooling tank designed for hydraulic and heating systems. Made by Reflex, model 8303400, the tank serves to absorb thermal expansion, stabilise system pressure and dampen temperature-related pressure fluctuations in closed systems such as boilers, chillers and other circuited heating or cooling plants.
Advantages
The Reflex V 40 l provides a compact, dedicated vessel for managing thermal expansion and relieving transient pressure peaks. It reduces the risk of frequent valve cycling and protects system components from overpressure. The unit is suitable for integration with a variety of closed-loop systems and is designed to work reliably under normal operating conditions encountered in residential and light-commercial plant rooms.
Suitable for
Boiler systems to absorb water expansion during heating
Chillers and cooling circuits requiring pressure stabilization
Closed-loop hydraulic systems in residential and small commercial installations
When it may not be suitable
The Reflex V 40 l is intended for closed hydraulic and heating systems; it is not suitable for open systems or systems that require diaphragm-free surge tanks. It may also be unsuitable where system volumes or expansion requirements significantly exceed 40 litres, or where specific certifications or materials are required for aggressive media.
Key specifications
Nominal volume: 40 litres
Application: expansion and cooling tank for closed hydraulic and heating circuits
Function: accommodates thermal expansion, stabilises pressure and reduces pressure peaks
Typical installations: boilers, chillers, closed-loop heating and cooling systems
How to use
Install the Reflex V 40 l on a suitable support near the system piping in accordance with local regulations and the system design. Connect the tank to the system at the designated expansion connection point, ensuring correct orientation and secure fittings. Pre-charge and set the tank according to the operating pressure recommendations of the heating or cooling system, then verify system tightness and proper pressure behaviour during initial fill and heat-up cycles. Regularly inspect connections and pressure behaviour as part of routine maintenance.
What to consider before purchase
Confirm the 40‑litre nominal volume is sufficient for your system expansion needs
Ensure compatibility with closed-loop systems and the working pressures of your installation
Check installation space, connection orientation and local codes for mounting and pressure equipment
Usage recommendations
For reliable operation, match the tank pre‑charge to system static pressure, mount the tank in a protected, accessible location, and include it in periodic system inspections to verify pressure stability and leak-free connections.
