Liquid Nitrogen

Background
The Defense Microelectronics Activity (DMEA) operates semiconductor fabrication clean rooms and other laboratory processes that require semiconductor grade, high purity nitrogen (N2) gas at 105 psi, as well as liquid N2 for laboratory use. The purpose of this contract is to provide continuous uninterrupted N2 supply (both liquid and gaseous) and continued rental of contractor, Messer, on-site liquid N2 to gaseous N2 conversion system and Dewar filling system to support DMEA operational needs. The sole source award will be made to Messer LLC based on 13.501(a)(1)(ii) and 13.501(a)(2)(ii), soliciting from a single source.

Work Details
The contractor, Messer, shall continue to provide their existing on-site N2 system consisting of a liquid N2 storage tank, dual, triple or quad switchable heat exchangers (vaporizers) to convert the liquid N2 to gaseous N2, piping, gauges, regulators, valves, a filling station for DMEA’s portable liquid N2 “Dewar” tank, remote monitoring equipment and an output header for DMEA’s connection to the building piping.
The contractor shall also provide on-going maintenance support of the N2 system, quality control and provide liquid N2 product resupply based on DMEA operational demands.
The usage rates range from approximately 71,000 gallons (6.6 million standard cubic feet (FTS)) of liquid N2 per month to 78,000 gallons (7.3 million FTS) of N2 per month with a peak N2 gas demand of approximately 132 gallons/hour (12,290 FTS/hour).
The contractor shall also deliver bulk liquid N2 to DMEA based on tank remote leveling sensors or within 4 hours of notice received from a DMEA telephone call.
