73 -- TRAY RATION HEATING SYSTEM SOL M67854-95-R-2139 POC Glenn Cruze, CONTRACTING OFFICER, CODE CTQ-3GC, (703) 640-5822, Ext. 226. The Marine Corps Systems Command intends to award a sole source contract to Babington Engineering, 113 Ingleside Ave. McLean, VA. 22101 for the procurement of Non-Developmental Item (NDI) Tray Ration Heating Systems (TRHS). Babington Engineering is a small business concern and the Standard Industrial Classification (SIC) code is 3569 and size is 500 employees. The Tray Ration Heater (TRH) is comprised of a burner assembly, on-off switch assembly, stainless steel water heater tank assembly with removable tray pack racks, and stabilizing devices. Other system components include burner fuel supply system, electrical power invertor with receptacle, maintenance kit with spare burner, and other ancillary equipment. The Marine Corps intends to purchase a minimum of 363 TRHS units in fiscal years 1995 through 1998 with options for additional quantities. Principal (Required) Characteristics: (a) TRH shall heat standard hot tray packs while being transported on the back of a High Mobility, Multipurpose Wheeled Vehicle (HMMWV) to remote sites under off-road conditions. (b) has capability to feed 250 personnel at single site within 90 minutes. (c) variable thermostat shall maintain a water temperature from 100 - 2000F. (d) heats 18 tray packs every 40 minutes to serving temperature of 180oF q 5oF. (e) burner ceases operating when water temperature reaches selected temperature q 5oF (f) automatic restart when the water temperature drops to 5oF below setting. (g) uses start-up power from the 24 VDC HMMWV electrical system,or from any 120 VAC, 60 Hz source. (h) fully installable on a HMMWV with tiedown clamps and straps without using material handling equipment. (i) ready for operation upon filling the tank with potable water and connecting fuel and electrical power. (j) continuous operation for 10 hours on 5 gallons of fuel (DF-1, DF-2, DFA, JP8 or kerosene (gasoline excluded)). (k) 5-gallon fuel supply, independent of the vehicle supply, shall be installed for use inside the HMMWV or removed for non-mobile uses within one minute. (l) fuel line quick disconnect for removal of the fuel tank from HMMWV without fuel line leakage. (m) burner goes to automatic lockout within 10 seconds of interruption of fuel supply or other malfunction that prevents burner light-off. (n) operable instantaneously with a single switch when resupplied with power and fuel. (o) low water level sensor to cause burner to cease to operate when water level too low. (p) water temperature thermometer with scale range of at least 80 - 210oF. (q) mercury tilt switch shuts the burner off in the case of accidental turnover or tilt in excess of 30 degrees. (r) the water tank shall be free of all protusions, heat exchanger tubes, or other components so as to provide a clean tank which meets National Sanitation Foundation (NSF) standards. (s) the system must operate from start-up to shut-down without smoke or oder. (t) system shall operate at steady state defined as 30 seconds after light-off at CO levels not to exceed 10ppm. (u) burner shall have an infinitely variable firing rate from 25,000-80,000 BTU/hr by means of a simple adjustment and with no parts change. (v) system shall consume no more than 125 watts of power @ 115 volts including start-up power draw. (w) burner safety features shall include proof of flame, automatic relight in the event of flame out, and lockout with manual reset in the event that re-light is not accomplished in 10 seconds. (x) the system shall be self priming and incorporate a fuel safety device to prevent fuel overflow into the system. (y) the maintenance kit must provide a spare burner, key components necessary to allow easy field maintenance and a diagnostic control box to quickly identify faulty components. (z) the overall system shall allow the burner to be removed for inspection in less than one minute without tools and be replaced with a single screw driver. Environmental Operating Conditions. (aa) capable of performing its operational mission for 30 days without interruption due to mechanical, structural, or electrical failure in salt fog, humidity, vibration, high/low temperatures, and transit drop. (Mean-Time Between Operational Mission Failure). The Operational Availability (Ao) is 90%. (bb) equipment shall not corrode or otherwise show signs of damage when exposed to salt spray or fog. (cc) able to operate within humidity ranges of 100% at temperatures of 78oF and 0oF, and 3% at 125oF. (dd) operable under vibration conditions associated with normal military transportation and combat areas. (ee) capable of normal operations in ambient temperature conditions for hot and cold locations. (ff) low temperature operating extreme is -25oF. (gg) high temperature extreme is 125oF. (hh) can withstand flat or rotational drops of 12 inches (300 mm) onto a concrete surface without loss of operation. Vendors who have the capability to provide the requirements for this contract should submit in writing technical qualifications along with independent laboratory results to verify that their candidate system meets all of the above stated requirements criteria not later than 20 Feb 1995. Only fully qualified vendors with a ready production capability should respond. This information should be mailed to: COMMANDER, ATTN CTQ 3GC, MARCORSYSCOM, 2033 Barnett Avenue, SUITE 315, QUANTICO VA 22134-5010. Proprietary information shall be protected and should be clearly identified. See Numbered Note 22. (0009)
