FDC Philadelphia Copper Coil Storage Water Heater

Storage heater shall be factory assembled and packaged. Water heater shall be constructed in accordance with ASME Code for a working pressure of 125 psig. The packaged water heater shall be constructed with a horizontal steel tank, cement lined with stainless threaded opening, 3/4" O.D. 90:10 Cupro-Nickel tubes, copper lined tube sheet, and steel or cast Iron coil head. Heater shall be mounted on a steel support skid and shall have concealed lifting lugs. Heater shall be insulated with 3" Fiberglass protected by an enameled metal jacket, 20 gauge minimum thickness. Heater shall be factory assembled and piped including air operated 3 way temperature regulating valve. Coil shall have copper wrapper, shall be baffled and shall have an Integral valved circulator to circulate the water across the coil into the bottom of the tank. Heater shall be supplied with solid-state control module with LCD touch screen display and LED pilot lights to indicate on-off, primary high limit, and secondary high limit. Solid-state control module shall be provided with a field programmable digital electronic PID controller allowing the owner to set operating and temperature limits on the display screen. Solid-state control module shall have red alarm light and alarm horn with built in alarm silence relay. Solid-state control module shall be supplied with dry contact closure outputs to indicate to building automation system (BAS) the occurrence of power on, primary high temperature, and secondary high temperature. The control module shall allow the BAS to turn the heater on or off through a remote contact closure. The control module shall allow the BAS to remotely set the temperature of the heater using a 4-20 mA input signal. The control module shall allow the BAS to remotely monitor the operating temperature via a 4-20 mA signal. Control module shall communicate with the BAS using Modbus protocol via an RS-485 connection. Control module shall be supplied with an on-off switch and shall be mounted in a NEMA 4 panel. AU solenoids and limits shall be 24 VAC. Heater shall be furnished with a water pressure gauge and an A.S.M.E. pressure-temperature relief valve of sufficient size to relieve total BTU Input of the coil. Furnish water heater with additional safety system designed to relieve excessively heated water from the vessel. The safety system shall be field programmable for set point and differential and shall be of the electronic type. Manufacturer shall assume responsibility for correct sizing of components to assure performance designated in design criteria. Tank dimensions 60" diameter x 96" long. · Storage gallon capacity 1000 Gallons. Standard flow design. Coil to heat 1600 GPH from 40 °F to 140 °F with 68.07 GPM of 220 °F inlet-180 °F outlet Hot Water.
