Pollution Control

Sustainable by Design

The Global Aire Pollution Control Unit, PCU Series, is designed specifically for the removal of grease particles and abatement of smoke from the air stream of commercial kitchen exhaust systems. The unit, if ordered with the optional odor control section, will reduce odors from the air stream. The PCU is designed for use with a high efficiency self-cleaning or baffle ventilator but may be used with other high efficiency exhaust hoods.

Overview of all the pieces and parts that make up the CORE Fire Protection System.

CORE Circuit Board

The CORE Fire System printed circuit board is a microprocessor based control that provides all the necessary monitoring, timing and supervision functions required for the reliable operation of the CORE Protection Fire System. If a fault is detected anywhere in the CORE system, the audible alarm will periodically sound and the “Fire System Activated” light will flash a fault code to indicate the specific fault detected.

Supervised Loop

The supervised loop incorporates both redundancy and fault detection. It is the means by which fire sensors and pull stations are connected to the CORE system.

Electric System with Battery Backup

The detection and pull station for CORE comprise an electric circuit that is connected to a battery backup system. In the event of a power outage, the power to all gas and electric appliances must be disrupted through the use of electric gas valves or shunt trip breakers. The battery powers the detection and pull station circuits, as well as monitoring those devices.

CORE Control Cabinet

The CORE Control Cabinet contains most of the necessary components for the fire system to function. The control cabinet holds the manifold, surfactant tank and pump, CORE control board, power supply and battery backup.
