Since Fred Hansen's invention of the quick-release coupling in 1915, the Hansen name has become synonymous with setting new industry standards in fluid conveyance, earning a global reputation for performance, resilience, and reliability. The innovative design of Danfoss Hansen's quick disconnect couplings allows for higher flow rates and an optimized flow path, resulting in reduced pressure drops and increased overall system efficiency. This, in turn, lowers application energy consumption, reduces system space and weight, and decreases component wear and tear, ultimately leading to reduced fuel consumption and cost of ownership.
As standard, Danfoss Hansen quick disconnect couplings are equipped with Dura-Kote™ plating, which provides exceptional corrosion protection, preventing red rust for up to 1000 hours, thus extending their lifespan and reducing maintenance demands.
Our updated Danfoss Hansen product line provides customers with a plethora of options. With a wide range of materials and sizes available, coupled with optimized sealing solutions, our couplings are highly customizable based on the performance and cost requirements of a specific application.
performance and cost requirements of a specific application.
Why use a quick disconnect coupling over a conventional threaded connection?
Traditional threaded fitting:
- No shut-off system: leakage after disconnection
- Cannot rotate while connected - line twisting decreases life of hose
- Additional assembly time
- Difficult handling, waste of time to disassemble (maintenance)
- Frequent disconnection effects seating performance, increases likelihood of leaking
Quick disconnect coupling:
- Shut-off system: sealing achieved upon disconnection
- Can rotate while connected, taking stress out of hose and extending life
- Ease of assembly in tight spaces
- Easy and fast to use (without tool), time saving and economical
- Increased mobility and access for maintenance
