Description

The Danfoss FD83-2128-32-32 is a 2-inch Hansen FD83 quick-disconnect coupling with sanitary flange connections for liquid cooling and fluid transfer systems. Its stainless-steel construction, EPDM seal, and dual interlock are suited to data center thermal management applications.

Technical Specifications

Information About FD83-2128-32-32

The FD83-2128-32-32 is part of Danfoss Hansen’s FD83 coupling series, developed for high-flow thermal management and industrial fluid circuits. This model has 2-inch sanitary flange ends compatible with DIN 32676, ISO 2852, and BS 4825 standards. The coupling uses a two-way valve arrangement and a dual-interlock safety mechanism that controls connection and disconnection. Verify flange standard, fluid compatibility, and operating limits against the system before installation.

Key Features: 

• Quick-Disconnect Design: Provides a connection point for liquid cooling and fluid transfer circuits that require coupling halves to be connected and disconnected.
• 2-Inch Sanitary Flanges: Uses 2-inch flange ends designed for DIN 32676, ISO 2852, and BS 4825 sanitary flange standards.
• FD83 Series Construction: Belongs to the Danfoss Hansen FD83 series, intended for data center cooling, thermal management, and industrial fluid transfer.
• Stainless-Steel Body: Uses stainless steel for the coupling body in fluid circuit applications.
• EPDM Seal Material: Uses an ethylene propylene seal; confirm compatibility with the specific circulating fluid and temperature conditions.
• Dual Interlock: Safety mechanism helps prevent the valves from opening before connection and prevents disconnection until the valves are closed.
• High-Flow Capacity: Manufacturer data lists a flow rate of up to 211 L/min for the 2-inch FD83 coupling.
• Operating Limits: Rated for up to 10 bar working pressure and 21 bar minimum burst pressure, with a listed working temperature range of −3°C to 60°C.

The FD83-2128-32-32 delivers the reliability and precision required for high-flow thermal management and fluid transfer connections.
