- Description
- The Naval Air (NAVAIR) Systems Command, (NAVAIR Lakehurst, NJ) anticipates the need for a temperature bath procurement to update/replace the current inventory of older model temperature baths and is seeking sources and /or information. The temperature bath or baths must be commercially available, "off the shelf" items with existing product specifications, manuals, technical information and test results that can be made available for comprehensive review and/or evaluation as required. As previously stated, this is NOT a developmental item and, as such, the Navy's goal is to avoid the prolonged waits, developmental costs and re-engineering associated with developmental type procurements. NAVAIR Lakehurst is requesting information regarding any commercially available products capable of meeting the requirements as set forth below (spec's, tech manuals, product brochure's, etc). Product availability for evaluation, if required, is requested. NOTE: While this is not a complete specification, it serves to set the approximate technical parameters for any potential competition should the government decide to issue a request for procurement (RFP). Temperature bath standards are used primarily in NAVAIR depot-level calibration facilities, including the regional labs, Mobil Calibration Complexes (MCCs) and several FCAs (field calibration activities) having special capability. These standards are used to support a wide range of workload items that cannot physically fit into the Portable Temperature Calibrators (PTCs) and/or require a higher degree of calibration accuracy than the PTCs can provide. Furthermore, their larger access opening size enables calibration of the multiple Test Instruments (TIs) simultaneously. The following provides a listing of several types of TIs that are calibrated with the temperature baths: Liquid In Glass Thermometers Bi-Metallic Thermometers Remote Indicating Thermometers Temperature Switches Thermistors Digital Multimeters Pyrometers Digital Indicators Thermocouple Thermometers Digital Thermometers Unless otherwise indicated, the specifications below are written around a single bath; although, it may be necessary to employ a system of baths in order to satisfy all of the requirements. The requirements for the temperature baths are as follows: POWER: The temperature bath shall operate on 115 VAC and less than 20 amps. DRAINAGE: The temperature bath shall have a drainage system to permit drainage of the bath fluid. TEMPERATURE RANGE: The bath, or system of baths, shall cover a temperature range of -40 ?F to 1000 ?F. FUME HOODS: The bath and corresponding bath fluid shall be chosen such that they can be safely operated over the required temperature range (provided in TEMPERATURE RANGE) and the permissible exposure limits set forth in the 29 Code Of Federal Regulations 1910 (Occupational Safety and Health Standards) for any substances generated or intrinsic to the specific bath fluids without requiring the use of a fume hood. NOTE: Navy testing has indicated that certain bath fluids used over specific temperature ranges will not exceed the Short-Term Exposure Limit (STEL) and Permissible Exposure Limit (PEL) set forth in the 29 Code Of Federal Regulations 1910: Dow Corning Corporation- Dow Corning 200? Fluid, 5 CST: -40 to 80 ?C Dow Corning Corporation- Dow Corning 200? Fluid, 50 CST: 60 to 180 ?C Heatbath Corporation- Tempering A-HTS PINK/PETRO AG: 180 to 550?C Although the temperature bath mediums are not limited to those indicated above, any and all conditions outside those previously stated must demonstrate the capability of satisfying the exposure limits set forth in the 29 Code Of Federal Regulations 1910 without the use of a fume hood or other similar ventilation device. Documented proof by an accredited Occupational Safety and Health Standards Agency must be provided. TEMPERATURE STABILITY: The stability for the bath and fluid shall be 0.011 ?F (0.006 ?C) or better at any temperature set point within the temperature range requirements for approximately a 30-minute duration (sufficient time for TI to stabilize and to make a measurement). This stability shall be achievable while using the same fluid. If multiple bath units are necessary to cover the temperature range, then each bath shall provide the aforementioned stability over the range the bath and fluid will be used. A stirring mechanism within the bath is preferred in order to expedite and maintain stability and uniformity throughout the bath fluid or medium. IMMERSION DEPTH: The temperature bath shall be able to provide a minimum immersion depth of 12 inches. WORKING VOLUME / ACCESS OPENING: The access opening shall be at least 4" in diameter (circular), 4" x 4" (rectangular or square) or equivalent. Larger access opening is preferred to facilitate the calibration of multiple workload items simultaneously. The working volume shall be comprised of, at a minimum, a depth of 12 inches and a diameter of 4 inches. This volume shall be unobstructed. TEMPERATURE BATH MEDIUM: The temperature bath medium shall be chosen such that the following hold: 1) One bath fluid or medium for the temperature range over which the bath will be used. If more than one bath is used to cover the temperature range requirement (-40 to 1000 ?F), then a bath fluid shall be selected such that it is not necessary to change / exchange the fluid in order to cover the range over which the bath will be used. 2) The use of the bath fluid or medium over the operating temperature range of the bath shall not require the use of a fume hood as a result of hazardous substances (i.e., fumes/vapors) generated by the fluids and/or to remove displaced particles (i.e., aluminum oxide, sand, etc.) in the air due to use. 3) To reiterate from the TEMPERATURE STABILITY requirement, the bath fluid or medium shall satisfy the stability requirement over the temperature range requirement. If more than one bath is used to satisfy the temperature range requirement, then the fluid in each bath shall be stable over the entire temperature range that the bath is used. SAFETY FEATURES: A label with the maximum safe operating temperature in accordance with the temperature bath medium requirements is preferred. If the temperature bath is capable of operating at temperatures that exceed the safe operating temperature range of the bath fluid, there shall be some mechanism to prevent the operator from operating the bath beyond the safe operating temperature of the bath fluid. Additionally, there shall be some mechanism to disable the unit or shut the unit down in the event of thermal runaway. TEMPERATURE CONTROLLER AND DISPLAY: The temperature display shall provide a visual indication of the current bath temperature. Additionally, the following shall be prevalent: SET-POINT RESOLUTION: The temperature bath display shall provide a set-point resolution of 0.001 ?C / ?F or better. TEMPERATURE SET-POINT: The temperature controller shall accept a desired temperature set point and the bath able to achieve that set point within an acceptable time period. TEMPERATURE UNITS: The temperature display shall provide temperature indications in the following measurement units: 1) Celsius (?C) 2) Fahrenheit (?F). HEATING AND COOLING TIME: The bath shall permit the calibration of a test instrument at a minimum of 4 equally spaced test points (including -40 ?F and 1000 ?F as the minimum and maximum test point values, respectively) within a 6-hour period. This time period includes the time necessary for the bath and the corresponding fluid to heat and/or cool while in transit to the test points and also to stabilize with the test instrument and/or standard monitoring device for measurements made at all four test points. FLUID LEVELING CAPABILITY: There shall be a mechanism/fixture that permits the bath fluid or medium to be brought to a suitable working depth for particular workload such as the liquid in glass thermometers and short-stem dial thermometers. This fluid-leveling capability may result from the actual construction of the bath or an appropriate adjustable leveling fixture that permits the TI to be brought to the level of the bath fluid. MULTIPLE BATH UNITS: Although a single bath capable of satisfying all of the requirements is desired, there are limitations imposed by the bath fluids themselves. Hence, it may be necessary to employ a system of baths in order to satisfy the requirements. If more than one bath is necessary to satisfy the requirements (i.e., cover the temperature range), the following shall be considered during the evaluation (i.e., all else being equal, a three-bath system occupying only x amount of space will be selected over another system occupying 2x amount of space): 1. Combined total volume of the system, including additional equipment necessary for operation (i.e., compressor). 2. Total square footage of lab space occupied by the baths. INTERFACE: The temperature bath shall have at least one standard IEEE-488 parallel interface for data transmission and reception for automated calibration and bath monitoring. All responses are to be faxed to Debbie Dewyea, Contract Specialist, at 732-323-7192 or emailed to: dewyeadl@navair.navy.mil by the end of business on 31 JUL 2002. The telephone number is 732-323-7068. THIS IS NOT A REQUREST FOR PROPOSAL. No solicitation package is available. Respondents to this request for information are invited to submit a statement of general interest, a description of any currently available unit which meets our requirements and /or a discussion on the feasibility of the above described unit. Any comments provided may/may not be included in a formal solicitation. The Government will not pay for any information received in response to this RFI nor will the Government compensate any respondent for any costs incurred in developing the information provided to the Government.
