As summer approaches, it’s the ideal time to review and optimise your plant room setup. At CORE, we offer a comprehensive range of high-performance plant room equipment and water treatment solutions to keep your systems running efficiently throughout the year. From precision-engineered pressurisation units to our award-nominated CORE magnetic side stream filter, we offer everything you need to future-proof your plant room.
NEW & Exclusive - CORE Side Stream Magnetic Filter
This cutting-edge, easy-to-assemble filter offers three products in one: a Magnetic filter, an air & dirt separator and a dosing pot. It is designed to remove magnetic and non-magnetic debris while maintaining system performance. Manufactured in the UK, the product features a high-capacity magnetic core, an easy-clean design, no consumables and a modular package that simplifies setup and reduces waste.
Key features include:
- Magnetic core: The unit features the largest magnetic core on the market, capable of capturing up to 1.8kg of ferrous debris.
- A 150-micron stainless steel mesh pot: The pot captures non-magnetic dirt, such as limescale, eliminating the need for additional system accessories, like flow meters or pressure gauges.
- Dosing pot: To eliminate the need for buying disposable cartridges, the unit features a dosing pot that can be filled with CORE chemicals, such as Biocide, to prevent microbial growth within the system and kill 100% of the bacteria, eliminating the need for disposable cartridges.
We are excited to announce that the CORE Magnetic Side Stream Filter has been shortlisted for the following awards:
- Energy-Efficient Partnership of the year
Constructing Excellence East Midlands Awards 2025:
- Regeneration & Conservation Awards
- Retrofit Award
