- THIS IS A COMBINED SYNOPSIS/SOLICITATION FOR COMMERCIAL ITEMS PREPARED IN ACCORDANCE WITH THE FORMAT IN FAR SUBPART 12.6-STREAMLINED PROCEDURES FOR EVALUATION AND SOLICITATION FOR COMMERCIAL ITEMS-AS SUPPLEMENTED WITH ADDITIONAL INFORMATION INCLUDED IN THIS NOTICE. THIS ANNOUNCEMENT CONSTITUTES THE ONLY SOLICITATION; QUOTATIONS ARE BEING REQUESTED, AND A WRITTEN SOLICITATION DOCUMENT WILL NOT BE ISSUED. THIS SOLICITATION IS BEING ISSUED USING SIMPLIFIED ACQUISITION PROCEDURES.*****This solicitation is a Request for Quotation (RFQ). The solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular 2001-07.*** The associated North American Industrial Classification System (NAICS) code for this procurement is 334513 with a small business size standard of 500 employees. This acquisition is unrestricted and all responsible offerors may submit a quote.***The National Institute of Standards and Technology (NIST), Neutron Research Division, has a requirement for an closed cycle refrigeration unit and air cooled compressor.***All interested offerors shall provide a quote for the following line items: LINE ITEM 0001: Quantity one (1) each closed cycle refrigeration unit and air cooled compressor meeting the following required specifications: 1.)Operating temperature range of 7- 800 K. 2.)Minimum Refrigeration capacity: 8 watts in the temperature range 20 K - 100 K, 16 watts above100 K. 3.)Cool down time from room temperature to 7K less than 120 minutes. 4.)Power requirements: 208Volts/Single Phase/60 Hz. 5. )Maximum power consumption: 2.5Kw. 6.) Gas compressor designed specifically for high purity helium gas. 7.)System shall run continuously, without interruption, for at least 30 days. 8.) Compressor shall include an hour meter that tracks operating time. 9.)Minimum scheduled maintenance interval: 5000 hours. 10. )Water consumption for cooling, if required, shall not exceed 18 liters/minute. 11.)Stainless Steel, braided, flexible hoses for high purity helium shall be ? inch I.D. and 15 feet in length. 12.)Cold head shall have a power cord at least 16 feet in length. 13.)Maximum cold head weight: 40 lbs. 14.)Cold head shall operate at any inclination up to 90 degrees from vertical. 15.) Maximum cold head diameter shall not exceed 12 inches (305mm).******In addition, the cryostat shall have customized features to interface with existing NIST equipment as set forth below: 1. Interface to existing NIST equipment. The interface to existing NIST equipment consists of three nested parts: Vacuum Can Flange, Heat Shield Mount, and Sample Stage Mount. The three parts are arranged such that the sample stage and heat shield mounts protrude below the outer vacuum can flange. The vertical distance from the base of the sample stage mount to the end of the heat shield mount is 0.75 inches, and the distance from the sample stage mount to the bottom of the outer vacuum can flange is 2.25 inches. 2. Vacuum Can Flange. The vacuum can flange shall consist of six tapped ?-20 holes on a 6.375 inch bolt circle. The flange face finish shall be 16 micro inches. 3. Heat Shield Mount. The heat shield mount shall be detachable, and thermally connected to the first stage of the cold head. The heat shield mount shall consist of an external 3.5"-24 thread, 0.188 inches in length. 4. Sample Stage Mount. The interface between the sample stage mount and the sample block shall be coordinated between the manufacturer and NIST in a manner that provides a non-rotating, stable connection. 5. Vacuum pump out ports. There shall be three (3) KF25 vacuum pump out ports which extend above the motor housing. The KF25 flanges shall face upward. 6. Wiring configuration. The external wiring connection shall consist of a single 19 pin connector mounted on one of the KF 25 vacuum pump out ports. The internal wiring shall connect three (3) temperature sensors (A, B, and C) and a heater. The wiring shall consist of the following: (a) NIST shall supply a Detoronics model DTIH-14-19PIN or equivalent electrical connector appropriately mounted to a KF 25 vacuum flange. ; (b) Cryostat pin assignment to sensor A: K/SensorI+; L/Sensor I-; N/Sensor V+; P/Sensor V-.; (c) Cryostat pin assignment to sensor B: U/Sensor I+; V/ Sensor I-; R/Sensor V+; D/Sensor V-.; (d)Cryostat pin assignment to sensor C: J/Sensor I+; T/Sensor I-; S/Sensor V+; E/Sensor V-(e) Cryostat pin assignment to heater: M/htr+; A/htr-. 7. Sample block and heater. (a) NIST shall supply the sample block to be attached to the sample stage mount; (b) Heater elements shall be wired to pins M and A of the connector specified in 6 (a) above. 8. Temperature sensors. (a) Sensor A shall be a calibrated Lakeshore PT-103-14J platinum resistor or equivalent. The salient characteristics of this platinum sensor are a calibration range that spans 15-800 K and an accuracy of +/- 50 mK at 100 K and +/-75mK at 300 K. Wiring for sensor A shall have a free length of 6 inches where the sensor attaches, to provide for remounting the sensor. Sensor A shall be mounted on the sample block provided by NIST.; (b) Sensor B shall be a type K thermocouple (Chromel-Alumel), with a useful temperature range of 4-800 K. Sensor B shall be mounted near the heaters to provide good control of the system.; (c) Sensor C shall be a Chromel-Gold/Iron (0.07 %) thermocouple with a useful temperature range of 4-600 K. Wiring for sensor C shall have a free length of 6 inches where the sensor attaches, to provide for remounting the sensor. Sensor C shall be mounted on the sample block provided by NIST. 9.Helium hose connection. The two helium hose connection fittings on the cold head shall face upwards and shall extend above the motor housing. 10. Temperature Regulation. Stable temperature regulation shall be attainable throughout the operating temperature range using one of the following temperature controllers currently available at the NCNR: (a) Lakeshore Model LS331 or LS340, or (b) Neocera Model LTC-21 or LTC-11. Temperature regulation will be considered stable if the temperature can be maintained for at least one (1) hour within 0.25 K of the setpoint for temperatures below 50 K, and within 0.5 % of the setpoint temperature for temperatures above 50 K. The temperature controller is not part of this solicitation. 11. Protection circuitry. The cold head shall be protected internally from overheating by the installation of a thermal switch, which interrupts current to the heater when the temperature of the cold head exceeds the manufacturer's specifications. 12. NIST shall approve final drawings before manufacture. Options: 1. Air-cooling option. Allows operation of compressor without the use of externally provided cooling water. The entire system (compressor, cold head, air cooling option) shall be powered by only one electrical power cord.***Delivery shall be FOB DESTINATION and shall be completed not later than 45 days after receipt of Purchase Order.***The Contractor shall pack and mark the shipment in conformance with carrier requirements, deliver the shipment in good order and condition to the point of delivery specified in the purchase order, be responsible for loss of and/or damage to the goods occurring before receipt and acceptance of the shipment by the consignee at the delivery point specified in the purchase order; and pay all charges to the specified point of delivery.***The Contractor shall deliver the equipment to NIST, Shipping & Receiving, 100 Bureau Drive, Gaithersburg, MD. ***Award shall be made to the offeror whose quote offers the best value to the Government, technical, price, and other factors considered.
