Running a grease duct to the roof can cost approximately $11,000 per floor, plus additional costs for duct access and cleaning on each floor. PCUs, on the other hand, can be side-vented, capturing a significant amount of grease and other contaminants, resulting in lower cleaning expenses.
Some companies, like CaptiveAire, offer PCUs with advanced features such as filter monitoring and electrostatic precipitator technology, which can help extend the life of filters and reduce maintenance costs. These units are designed to remove grease particles, smoke, and odours from commercial kitchen exhaust systems.
It is worth noting that while PCUs are not required by law in all states and municipalities, many restaurant owners are choosing to invest in them to prevent grease, smoke, and odour pollution, as well as to reduce operating costs.
The system utilizes a water spray system for fast flame knock-down and suppression. It includes an electric thermal detector located in the intake and outlet of the ductwork connection. When the system detects a temperature hotter than its internal setpoint, an electric signal is sent to the CORE Fire System Cabinet, activating the water solenoid and allowing water to flow to the mounted manifold.
The CORE Fire System printed circuit board is a microprocessor-based control that ensures reliable operation by providing necessary monitoring, timing, and supervision functions. It is important to note that the CORE PCU control panel is limited to interior applications and must be designed and installed according to the guidelines provided in the manual.
