Dual - Gasket Solution for Thermal Systems
The EPDM gasket, engineered for high - temperature steam applications, withstands up to 150°C while resisting chemical corrosion and thermal aging. Its formulation ensures long - term elasticity, maintaining leak - proof seals in steam - to - water heat exchangers used in food processing or pharmaceutical sterilization. During production, EPDM gaskets are vulcanized onto 316L stainless steel plates, creating a seamless bond that complies with FDA and ASME standards.
Conversely, the NBR gasket excels in refrigeration systems, offering superior oil resistance and resilience under pressure fluctuations. Ideal for plate heat exchangers in industrial freezers or HVAC units, it prevents refrigerant leakage and maintains thermal efficiency. The NBR material's compatibility with ammonia and freon refrigerants makes it a reliable choice for harsh chemical environments. Both gaskets are precision - molded to fit the chevron corrugation of the plates, maximizing turbulence and heat transfer coefficients (up to 8,000 W/m²K). This dual - gasket approach ensures the heat exchanger adapts to varied processes, from dairy pasteurization (EPDM) to cold storage cooling (NBR), while minimizing maintenance downtime.
This dual - gasket offering combines EPDM and NBR gaskets for versatile thermal applications. EPDM handles high - temperature steam (up to 150°C) in steam - to - water exchangers, resisting chemicals. NBR excels in refrigeration, withstanding oils and pressure changes, ideal for industrial and HVAC systems.
Product Details
Core Components
◆ EPDM Gasket: Engineered for high - temperature steam scenarios (≤150°C). Resists chemical corrosion and thermal aging, maintaining leak - proof seals in steam - to - water heat exchangers for food processing, pharmaceutical sterilization, etc. Bonded to 316L stainless steel plates via vulcanization, meeting FDA/ASME standards.
◆ NBR Gasket: Optimized for refrigeration systems. Boasts superior oil resistance and resilience under pressure fluctuations. Prevents refrigerant leakage in industrial freezers, HVAC units, compatible with ammonia and Freon refrigerants.
Performance & Application
◆ EPDM in High - Temp: Ensures long - term sealing in steam - driven processes (e.g., dairy pasteurization, pharma sterilization), resisting thermal stress and chemicals.
◆ NBR in Refrigeration: Maintains thermal efficiency in low - temp systems (e.g., cold storage, HVAC), compatible with common refrigerants, boosting heat transfer (coefficient up to 8,000 W/m²·K).
Key Advantages
◆ Dual - Purpose Versatility: EPDM for high - temp steam, NBR for refrigeration-covers diverse thermal system needs (pasteurization to cold storage).
◆ Reliable Sealing: Precision - molded to fit chevron - corrugated plates, ensuring leak - proof bonds that comply with industry standards (FDA, ASME).
◆ Material Compatibility: EPDM suits food/pharma hygiene; NBR works with industrial refrigerants, minimizing cross - contamination and system failures.
◆ Efficiency Boost: NBR's design maintains turbulence, enhancing heat transfer coefficients for energy - efficient operation.
Technical Compliance
◆ EPDM meets FDA (food/pharma) and ASME (pressure systems) standards. NBR complies with industrial refrigeration material requirements, compatible with ammonia/Freon.
Packaging & Logistics
◆ Packaging: Gaskets sealed in anti - contamination, moisture - resistant bags. Shipped in boxes with plate - fitting guides to ensure integrity.
◆ Delivery: 5–12 days for standard orders. Freight options include temperature - controlled shipping for sensitive applications (e.g., pharma).
