41 -- DUAL MODE COOLING UNIT SOL N00164-96-Q-0420 DUE 091296 POC Contact point, Ms. Roberta George, Code 1163WK, 812-854-1348, FAX 812-854-3465; Ms. S. R. Burris, Contract Specialist The Navy requires 4 each Electro Impulse Inc. dual mode cooling units, Model Number51100, for installation on Coast Guard Cutters to improve water flow and water quality. Theequipment definition is as follows: The cooling unit transfers the heat from the load by means of aliquid to liquid heat exchanger in the secondary (ships water) coolant line. The cooling unit shallprovide indicator lights for loss of power, coolant over temperature, low coolant flow, lowreservoir level and a meter for measuring water resistivity. The cooling unit shall also have thebuilt-in test capability to test the indicators used for over temperature, low reservoir level and lowflow faults. resistivity. The interface definition is as follows: The cooling unit shall interface withthe AN/SPS-40E Radar through Unit 32. The Cooling Unit shall provide Unit 32 with 4.5 GPMminimum with a total 60 PSI drop through Units 28,29 and 32. Utilizing ships chilled water thecooling unit shall be capable of removing 18,050 BTU/HR. The dissolved oxygen content shallbe 0.5 PPM by weight maximum. The resistivity shall be 0.5 meg OHM/CM minimum. Thecoolant pressure should not exceed 125 PSI. Delivery shall commence within 60 days after theeffective date of the contract. F.O.B. destination terms apply with inspection and acceptance atNAVSURFWARCENDIV Crane. The acquisition of the Electro Impulse Inc. brand name cooling units is essential to the Government's requirements, thereby precluding consideration of aproduct manufactured by another company.
