Separators, Filters & Expansion
Our comprehensive range of components for ASHP systems is engineered to ensure optimal system performance, reliability, and longevity. Designed to support both domestic and commercial installations, the range includes:
Expansion Vessels (heating & potable): Maintain pressure stability and absorb system expansion to prevent damage and ensure safe operation.
Automatic Air Vents (AAVs): Efficiently remove trapped air from the system to improve circulation and reduce noise and corrosion risks.
Deaerators: Eliminate microbubbles and dissolved gases, protecting pumps and components from air-related issues and improving energy efficiency.
Air & Dirt Separators: Dual-function units that capture entrained air and debris, preserving system cleanliness and performance over time.
Magnetic Filters: Capture and retain ferrous particles to prevent sludge buildup, safeguarding key components like pumps and heat exchangers.
Strainers: Provide essential pre-filtration, blocking larger debris from entering the system and extending the life of valves and other critical elements.
Each product is designed for easy installation, low maintenance, and maximum compatibility with modern ASHP systems, helping to ensure clean, efficient, and long-lasting heating performance.
