Engineered to be “virtually” monitored and/or programmed remotely using current web browsers on a laptop, table or smartphone, the Frick Quantum HD refrigeration controller allows multiple operators to log in and securely adjust settings or verify capacities without disturbing the current screen as it appears live. The home screen gives a snapshot overview of the most important settings and values. Single-touch controls allow operators to change capacity control and setpoints, as well as the mode for the compressor, capacity slide and volume slide. The controller integrates with almost any refrigeration screw compressor package.
