SPX Cooling Technologies has launched a range of control panels and monitoring equipment which simplifies cooling tower installation, operation and data collection. Marley control panels enable building management systems to conveniently communicate cooling tower conditions through visual displays, network communications and relay status outputs.
The Marley AIO (All-In-One) Control Panel reduces installation and startup time, as it uses single-point wiring in one convenient panel. Control functions integrated into the AIO Control Panel are customer-configurable based on job site requirements. A typical combination is the Variable Frequency Drive (VFD) for the fan motor, basin heater control, water level control, and vibration switch interface.
The Marley ABH (Advanced Basin Heater) Control Panel controls on/off operation of the cold water basin heater(s) to prevent freezing in cold environments. It features upgraded components, such as a visual display of water temperature and set point temperature that can then be adjusted as desired. A heater element test circuit provides predictive maintenance, and an optional temperature retransmission output may be selected for communication to a building management system. A main circuit breaker disconnect provides short circuit and overload circuit protection for personnel safety.
SPX also offers a range of vibration monitoring and protection products, from traditional mechanical switches to solid state switches with ‘smart’ features for more accurate measurement, as well as biological control materials.
