 Metal Filters for Heating and Refrigeration Systems

High-performance metal filters are essential components in modern heating and refrigeration systems. In heating technologies — such as boilers, heat pumps, and geothermal systems — as well as in refrigeration circuits, they ensure system protection, stable performance, and long operational life.

Manufactured from wire cloth or expanded metal, these filters are designed to withstand demanding operating conditions, including high pressures and significant temperature variations.

Why Metal Filters Are Crucial in Heating & Refrigeration

Protection of sensitive components
Metal filters capture solid particles, moisture, and impurities to protect compressors, expansion valves, control valves, evaporators, and pumps. This prevents wear, clogging, and malfunction — especially in systems operating under high pressure.

Improved efficiency and thermal stability
Clean fluid and refrigerant circuits ensure correct flow, optimized heat exchange, and reduced risk of pressure drops or blockages. Mechanical filters and filter-driers maintain system purity, enabling consistent performance and longer equipment life.

Versatility across applications
Metal filters are suitable for small domestic units, commercial installations, and large industrial plants thanks to their durability and compatibility with diverse operating conditions.

Typical Applications

Metal filters are commonly used in:

• Refrigeration compressors (oil circuits and suction line protection)
• Expansion and control valves
• Heat pumps and hydronic heating systems
• Boilers and thermal units
• Chilled-water and process-cooling systems
• High-pressure refrigeration circuits
• Residential and commercial air-conditioning units
• Oil-return and lubrication circuits

Installed on the liquid line, suction line, discharge line, or oil-management circuit, metal filters maintain fluid purity and ensure the long-term reliability of all downstream components.
