Hydraulic Door Hinges: Guide and Types

Hydraulic hinges primarily come in two types: standard single-speed closers, which close the door at one consistent speed, and dual-speed closers like the Kason 1094S SureClose, which feature an initial fast-close phase followed by a slower snubbing action near shut. Mounting options include exposed and concealed models for different installation preferences.

They feature heavy-gauge steel and stainless steel construction that withstands cold, humid environments. Their controlled closure ensures the door seals properly every time, preserving temperature and reducing energy waste.

The Kason 1094 SureClose hydraulic door closer is life-cycle tested to operate reliably after 500,000+ closures. In a typical commercial food service environment, this translates to many years of dependable use, even in high-traffic locations like grocery stores, restaurants, and industrial refrigeration facilities.
