Product Overview
The DN300 PN25 Marine Chiller Rubber Compensator is a high-specification flexible joint specifically custom-engineered for vessel refrigeration and HVAC systems. Featuring a unique non-standard square flange design, it allows for seamless integration into specialized chiller heat exchangers where standard circular flanges fail to fit.
Constructed with high-grade EPDM for thermal stability and premium SS316 stainless steel for ultimate seawater corrosion resistance, this unit is rated for 2.5 MPa (PN25). To ensure operational safety under high-pressure surges, it is equipped with heavy-duty control rods to manage pressure thrust in critical maritime environments.
Key Features
- Custom Non-Standard Square Flanges: Precision-machined SS316 square flanges tailored to match specific marine chiller and evaporator interfaces.
- High-Pressure Reliability (PN25): Reinforced bellows construction designed to withstand 25-bar working pressure, ideal for modern high-efficiency cooling circuits.
- Ultimate Corrosion Resistance: SS316 stainless steel provides superior protection against pitting and crevice corrosion in high-salinity marine atmospheres.
- Integrated Thrust Restraint: Heavy-duty control rods (tie rods) prevent over-extension and protect fragile chiller nozzles from hydraulic shock.
- Thermal & Vibration Isolation: High-resilience EPDM effectively dampens compressor vibrations and accommodates thermal expansion in refrigerant loops.
Applications
- Marine Central Air Conditioning (Chiller) Units: Flexible connection for seawater condensers and evaporators.
- Vessel Provisions Refrigeration: Vibration isolation for large-scale onboard cold storage systems.
- Offshore Platform HVAC Systems: Reliable high-pressure joints for salt-spray exposed cooling networks.
- Industrial Process Cooling: Providing custom flanged solutions for compact heat exchanger modules.
