APPLICATIONS
Versatile and Reliable Solutions
Confit stainless steel press systems, offered under the assurance of Pnopar, exhibit high performance in the most demanding conditions with AISI 304 and 316L material quality and a wide product range from DN15 to DN150. Thanks to the specialized O-ring technology used, our system provides secure solutions across a broad spectrum, from domestic plumbing to heavy industry.
1. Potable Water and Hygienic Systems
Potable Water Lines: Since Confit systems do not release heavy metals into the water, they maintain the water’s purity. Our black EPDM gaskets, compliant with KTW and DVGW W 270 standards, ensure the healthiest transmission.
Water Treatment and Pure Water: Thanks to its high corrosion resistance (AISI 316L), it is ideal for de-ionized, softened, and distilled water lines.
Hot Water Heaters: It can be safely used at continuous operating temperatures up to 110°C.
2. Heating, Cooling, and HVAC
Closed and Open Heating Circuits: Delivers high performance in hot water systems (DIN 4751) with flow temperatures up to 120°C and pressures up to PN16.
Cooling and Refrigeration Lines: Provides a leak-proof guarantee for closed and open cooling circuits operating within the temperature range of -20°C to +120°C.
Water-Based Air Conditioning (Chiller) Systems: Fully compatible with water-glycol mixtures (up to a 50/50 ratio).
3. Industrial Process and Energy
Solar Thermal Systems: Offers seamless solutions for solar flow lines up to +200°C with our high-temperature and UV-resistant FKM (Green/Red) gaskets.
Compressed Air and Inert Gases: Suitable for compressed air lines, whether oil-lubricated (Class 5 – FKM gasket) or oil-free (Class 1-4 – EPDM gasket), according to the ISO 8573-1 standard.
Vacuum Lines: Ensures hermetic sealing in piping systems for non-medical purposes up to an absolute vacuum of 200 mbar.
4. Gas and Fuel Systems
Natural Gas and LPG: Fittings equipped with our specially approved yellow HNBR gaskets are used for natural gas (methane), propane, and butane lines.
Fuel Lines: Features sealing elements developed specifically for hydrocarbon-based fluids such as fuel oil, diesel, and biodiesel.
5. Firefighting and Heavy Industry
Sprinkler Systems: Thanks to the advantage of flame-free and spark-free installation, it ensures maximum safety during setup in fire-risk areas.
Shipbuilding and Railway: Demonstrates superior durability against vibration, corrosion, and seawater with AISI 316L grade quality.
Food and Chemical Industry: While the smooth surface of stainless steel meets strict hygiene standards, its high chemical resistance extends the service life of production lines.
