The Department of Veterans Affairs is seeking information from companies capable of replacing a Reverse Osmosis (RO) water heat exchanger. The heat exchanger has specific requirements, including a shell side and tube side with particular fluid flow rates, temperatures, and pressures. The replacement heat exchanger should have a total heat exchange of 1,049,499.92 Btu/h and an overall heat transfer coefficient of 305.1/262.93 Btu/hr,ft2,°F. The construction of the heat exchanger should include a shell side with a design pressure of 150PSI and a design temperature of 375°F, and a tube side with a design pressure of 125PSIG and a design temperature of 375°F. Interested companies should send an email to the contracting officer with their contact information, socio-economic status, and unique entity identifier (UEI) number. Some key points to consider are: • The heat exchanger should be able to handle a total flow rate of 106.26 GPM on the shell side and 60 GPM on the tube side. • The heat exchanger should be able to operate at a pressure drop of 6.5 / 1.84 PSIG on the shell side and 6.5 / 0.44 PSIG on the tube side. • The heat exchanger should have a surface area of 81.1 ft2 and an excess surface area of 1.32%. • The heat exchanger should be constructed with a tube material of 316 S/S and a diameter of 3/4 in. • The heat exchanger should have a head type/material of CAST SS316 and a tubesheet material of 316 S/S.
