What is the difference between hydraulic and mechanical hinge types?

Hydraulic hinge type slows down in a hydraulic zone while Mechanical hinge type closes mostly at an average speed from swing to latch.

What are the scenarios where hydraulic & mechanical hinges are needed?

Hydraulic hinges are needed in windy areas where you don't want your door constantly slamming whereas Mechanical hinges are needed for latching & self-closing purposes where no special speed adjustment needed.

What are the advantages of using a closer hinge?

Waterson Hinges meet ADA requirements, are aesthetically appealing, easy to install, and have complete adjustability in closing force and speed. They are the most durable hinge on the market with suitable application and have lower labor cost and cluttering compared to other types of closers.
