GD Connect 4 Compressed Air Management System

In today's world, no modern energy efficient compressed air system is complete without the installation of an intelligent master control system. The GD Connect 4 is the ideal control solution for smaller compressed air stations and will intelligently control up to 4 fixed speed compressors.

Potential Energy Savings up to 30%

 

The GD Connect 4 is designed to harmonize the complete compressed air station, ensuring that the system is correctly managed by optimizing equipment utilization and controlling the system pressure within the tightest band. Installation typically offers energy savings of up to 30%.

Easy Installation

Installation of any GD Pilot/GD Pilot MK controlled compressor is made easy with direct connection using data cable, eliminating the need for any additional communication interfaces. For other compressors, installation is quick and easy thanks to the use of an interface PCB. The system also features a user-friendly LED display for simplified operation. A clear and easy to use LED display gives an individual compressor status of each compressor within the system.
