Every component of your control system – from controllers, I/O cards and network equipment to computers and software – has an expectant lifecycle. If any component of the control system is at or near its end-of-life phase, the potential risk for production shut-down is significantly increased. Therefore, it is critical to know the age of all components of your control system, whether your system hardware and software are still supported by the manufacturer and the availability of spare parts so that you can avoid costly unplanned downtime.
Chilled water plants are sophisticated assets comprised of mechanical and electrical systems controlled by programmable logic controllers (PLCs). They play a critical role in the operation of a wide range of facilities, including power plants, industrial facilities and data centers, and are often designed to function with minimal operator interaction. However, even the most intelligent systems degrade over time and require some amount of service and tuning to maintain optimal performance.
Water (H2O), the most abundant substance on earth, is also a universal solvent. From rivers and lakes to seas and oceans, water is the main ingredient but its composition varies because of its solvent properties. As water falls through the air, it absorbs gases and picks up particulates such as dust and pollen. Then, as it trickles down through soil and rocks, it dissolves minerals along the way. As a result, water quality varies greatly both regionally and seasonally.
Water is also a highly effective heat transfer medium. Heat transfer is the process whereby thermal energy or heat moves from one body or substance to another, and from hot to cold. We’ve all noticed the large plumes rising from a hospital, hotel or a power plant.
The modular chiller plant is a self-contained chilled water production system. An efficient and affordable alternative to the traditional stick-built chiller plant, the modular chiller plant works equally well in a building mechanical room without an enclosure, and in an open environment with an enclosure to protect the components from the elements.
The modular chiller plant is pre-engineered and fabricated with all system components. Packaged in a skid, the module is pre-piped, wired, tested and shipped to the job site where the water and power connections are made.
Modular does not mean one-size-fits-all. The modular chiller plant can be designed for primary secondary, variable primary or fixed primary operation, and it can be customized to special engineering requirements for component type, manufacturer and model.
