2. Shell: Stainless steel ASME code construction with flanged piping connections. (150 psig) maximum WSP. 3. Tubes: Stainless Steel tubes suitable for (150 psig) working pressure. 4. Design: Heated fluid in shell and heating fluid (higher pressure steam) in tubes. 5. Each generator shall be furnished with the following accessories: a. Resilient insulation. b. Pilot operated modulating control valve with pressure controller. c. Control to maintain constant steam output. d. Pressure relief valve. e. Vessel and tube side pressure gages. f. Liquid level controller with brass feed water solenoid valve, in check valve and strainer. g. Over-pressure limit system with auto-reset. h. Factory packaging. i. Dual F&T condensate traps. j. Manual blow down k. //Time based//TDS based// automatic blow down l. Low water cut-off and high pressure cut-off. m. Fully wired control box. n. Automatic solenoid valve. 6. Provide solid state control module with LED backlit LCD display and LED pilot lights to indicate on-off, high pressure, low pressure, low water and water feed. Control module shall allow the local adjustment of pressure limits on display screen. Control module shall have alarm light and alarm horn with built in alarm silence relay. Control module shall be supplied with dry contact closure outputs to indicate to building automation controls (BAC) the occurrence of power on, high pressure, low pressure, low water and water feed. The control module shall allow the BAC to turn the unfired steam generator on or off through a remote relay suitable for 24 VAC, 1 amp. The control module shall allow the BAC to remotely monitor the operating pressure. Control module shall be supplied with an on-off switch and shall be mounted in a NEMA 1 panel. All solenoids and limits shall be 24 VAC.
