Danfoss Hansen Aluminium Flat Face ADB coupling is a flat
face/dry break coupling used for cooling systems in
electric applications with circulating water and antifreeze
fluids. This coupling is providing an enhanced solution for
preventing spillage of cooling agent which can cause
technical failures, system shutdowns, and difficult
clean-ups.
ADB Series (Aluminium)
Flat Face/Dry Break
Product Features
• Aluminium construction extends life for safer
operations and reduced maintenance.
• 4-times safety factor at maximum operating
pressure of 25 bar.
• Enhances operations in demanding
applications with heat and vibration
compared to plastic couplings.
• Options are available for railway applications
with an enhanced version for vibration
resistance tested according to EN 61373.
• Up to 62% higher 昀氀ow than ISO 16028
requirements to improve efficiency.
• Pre-guided system that helps users
pre-position the coupling in difficult
environments, making connection easy and
reducing maintenance time.
• Full range of optional seals, end connections
and sizes, helping manufacturers bene昀椀t from
the design in any type of application.
