Specifications include, but are not limited to: Hampden Model H-6878 - 6 Pass Heat Exchanger Demonstrator Unit should consist of the Test Bench (78"H x 94"W x 31"D, Weight 600 lbs) consisting of two leg and base assemblies, and one test panel. The leg assemblies and bases are constructed out of code gauge 2" square mechanical tubing finished in instrument tantexture. The test panel Is constructed of code gauge sheet metal with 4" formed back panel with 1-1/2" returns and is finished in instrument white enamel. This unit should come complete with two swivel and two locking swivel casters. Mounted on the test panel are two flowmeters with a +/- 2% full-scale accuracy, one digital thermocouple display meter cold junction compensated with a resolution of 0.1°C/0.1°F and accurate to within +/-0.4°C/0.8°F utilizing Chromel-Alumel thermocouples. The bench should come complete with 23 fixed thermocouples on the inlet and outlet of the ½” ID tubes of each heat exchanger pass and at the mixing valve. In addition, two thermocouple probes should be supplied which allow the taking of temperature readings at any point of the outer surface of each of the heat exchangers.
