MEP National Network Open Supplier Scouting Opportunities

For the construction of the new Energy and Minerals Research Facility (EMRF) for the U. S. Geological Survey (USGS) at the Colorado School of Mines (Mines), 1000 18th Street, Golden, Colorado 80401, provide a packaged high performance Vertical Flooded Steam to Water Heat Exchangers for Building Heat and Domestic Hot Water delivered to the EMRF construction site. This project is federally funded by the President Joe Biden’s Bipartisan Infrastructure Law (BIL). Therefore, the material used for construction is required to be compliant with the Build America, Buy America Act (BABAA). This NIST MEP Supplier Report seeks a BABAA compliant Heat Exchangers that meets or exceeds the basis of design. The basis of design is a Maxi-Therm steam to water heat exchangers described herein (including additional information). The basis of design heat exchangers meets or exceeds the design requirements including the strict technical requirements, maximum size requirements, maximum delivery schedule, and the maximum cost parameters enclosed. See also the requirements stated in the enclosed specifications, drawings, dimension and performance requirements, and other documents including warranty requirements. Packaged heat exchanger systems (pre-piped and wired controls assembled on a painted and fabricated equipment steel framed and ready for field piping connections) and associated components and accessories include, but are not limited to, the following: 1. Vertical U-tube. 2. Liquid and Steam piping to be Schedule 40 carbon steel. 3. Liquid Condensate piping to be Schedule 80 carbon steel. 4. Stabilizing pump and isolation valves and stainless steel check valve. 5. Modulating electric control valve on the condensate outlet, fail safe, pre-wired to the control panel. 6. Thermowells, electric temperature sensor, with thermometers located at the liquid inlet and outlet, and condensate outlet. 7. Pressure transmitter on steam inlet, flow sensor on the liquid inlet, overheat butterfly security valve on the steam side, start-up valve on the steam inlet. 8. NEMA 4 UL approved control panel, pre-programmed to include the following: a. Programmable controller with optimal control sequence. b. Factory wiring to all sensors and valves. c. Color HMI graphic interface with different users’ access levels. d. Access via the building automation system to all parameters for remote monitoring and remote control. e. BACnet (IP) communication protocols are available. f. IoT ready with data acquisition and secure remote access capabilities (ISO 27001 and ISECOM STAR certified) with OPC US Embedded Server. Internet connectivity must be provided to the panel via an ethernet cable by the customer for remote troubleshooting and monitoring. g. Continuous display and datalogging of liquid inlet, water outlet, condensate outlet temperatures, steam pressure, liquid flow in GPM, condensate control valve and main steam valve position (via the feedback output of the valves) and heat transfer rate in BTU/hr. h. Preprogrammed and adjustable alarms for liquid outlet high and low temperature, condensate outlet high temperature, high and low liquid flow as well as high steam pressure. Sensor/valve failure alarm is also standard. i. The outside disconnect switch to be able to locally shut the power to the panel before opening the door. j. Integral network switch and 120V power supply receptacle to plug in a laptop for easy tech support. Laptop can be plugged in with the control panel door closed for more safety. k. Return to last known state after a power outage. 9. Flanged steam trap on condensate outlet, strainer with 40-mesh and blowdown valve on condensate outlet.
