HOW TO PRICE A COMMERCIAL SYSTEM
TANK FILL (CONT.) • Submersible level transducer - This is a device that is submersed in water and works off of a pressure indication for the water above. Once water weight drops below a certain pressure, the system is indicated that there is not enough water in the tank to support usage. • Optical level transducer – This device uses an infrared signal to detect the amount of water in a storage tank. These sensors are not typically used in a stainless steel tank due to refraction giving incorrect readings. • Valves – Typical valves used in this application are isolation valves and check valves. • Some applications may require a pressure regulating valve. This occurs if there is a material used for the tank that cannot withstand the pressure of the water exerting a force on the side wall. DOMESTIC WATER BOOSTER • This application of a water booster is for the servicing of toilets, showers, bathtubs, sinks, etc. • These systems have a large range or capacity and pressure dependent on the building type and height. This application typically runs on VFD’s in our current time. • The use of pressure transducers is important when using VFD’s so that the VFD can speed up or slow down based on a pressure calculation done within the PLC. COOLING TOWER MAKE-UP • This application of a system is in place to provide cold water to the air handling units on top of buildings that work within the HVAC system. • The CTMU systems typically follow the same operation as a domestic water booster system. o Determine the correct pump for the application. (ex. If the application is a tank fill system, the correct pump selection would be a either a VMS or a segmented ring diffuser pump. • Valves o Determine what the application calls for. If the system is a constant speed system, without the use of VFD’s, the correct valve to use on the discharge of each pump would be a PRV. If VFD’s are used, a check valve should be used on each pump’s discharge. • Skid o The skid is an important piece of the system. It is what lies underneath the system and what is grouted in place to hold the system to the mechanical room floor. This can be arranged as a single piece or into multiple split pieces to easily dismantle and move the system into a tight space. • Piping o Piping is specific to every system application. Pipe material should always be compatible with the fluid being pumped. 304 Stainless Steel is the standard material used by SFI in the commercial market. Other materials such as 304L, 316, 316L, and fusion bonded carbon steel are available for use. When selecting the piping and valves, make sure that you take into consideration that most 150# valves have a low working pressure. Our standard is that after maximum system pressure exceeds 250psi, you will need to switch to 300# piping and valves. You can figure out what pressure class piping you need by a simple calculation. This calculation is as follows: pump shut off pressure + maximum suction pressure = maximum system pressure. • Control panel o The control panel is the brains of the system. It is what houses the VFD’s, PLC, and HMI. All of the control logic and incoming power wiring is contained within the control panel. You will find, in addition to the items listed above, transducers, relays, contractors, circuit breakers, fuses, and other products within the control panel enclosure.
