Demineralization filters

Demineralization filters in this category are designed for the filling and topping up of heating systems. These filters use mixed resin cartridges to reduce total mineral content in water, ensuring compliance with boiler manufacturer specifications. The filters are typically installed at the water inlet to remove dissolved minerals, preventing scale formation and prolonging system efficiency. They are suitable for use in central heating, industrial, and commercial systems where water quality is critical.

Available models include filters with 1", 3/4", and 6/4" connections, along with spare cartridges for various filter types. Conductivity meters are also included for monitoring water purity during the filling process.

How to choose

• Select the appropriate connection size (e.g., 1", 3/4") based on the inlet pipe or system requirements.
• Ensure compatibility with existing filter models (e.g., IVAR.FP DEMI, IVAR.FP DEMI BIG) when replacing cartridges.
• Consider the resin capacity and expected water hardness to estimate cartridge lifespan and replacement frequency.

Frequently asked questions

What is the purpose of a demineralization filter in a heating system?
A demineralization filter removes dissolved minerals from water, reducing the risk of limescale buildup in the system and ensuring the water meets the specifications required by boiler manufacturers.

How do I know when to replace the filter cartridge?
Some cartridges include an indicator that changes color when the resin is exhausted. Alternatively, monitor the conductivity of the output water using a conductivity meter to determine when the cartridge needs replacing.
