DescriptionThe Barnes & Jones Compact Trap is a low-cost, easilycleaned, disposable steam trap specifically designed foruse on process equipment including compartment and kettlecookers, stills, sterilizers, food, chemical and laundryequipment. lts small size and economy make it ideal for useon industrial tracer lines. Measuring only 3t/e" x 11s/.ra"(82mm x 49mm)the Barnes & Jones unit weighs just 4.5 oz(125 grams) compared with conventional traps weighing 2 to 4pounds (1 Io 2 kilograms). The unique and versatile steamtrap uses a patented design that incorporates a stainless-steel housing of low mass to permit the very rapidthermostatic response critical to optimum trap operation.

The low-cost units are readily used with a wide variety ofequipment by virtue of standard NPT fittings.

The Barnes & Jones Compact Steam Trap is calibrated toactuate within 5"F (3'C) of saturated steam temperature inbellows activated units and 12"F (7"C) of saturated steamtemperature in diaphragm activated units. Three differentactuators provide a range of operating pressures.Diaphram actuator for 0-80 psig (0-6 bar); Bronze bellowsfor 0-80 psig (0-6 bafl; and Monel bellows for 0-150 psig (0-10bar) range. Four standard NPT stainless-steel end fittings(from r/e" lo 1/2") allow users to specify any of twelve (12)standard models. For unique OEM applications, Barnes &Jones will provide custom end fittings. Used in one position,the Barnes & Jones device operates as a fast-acting steamtrap to evacuate condensate from steam cookers, sterilizers,etc. Mounted with the exit port in an upright position, itfunctions to quickly vent air and retain steam. ln eitherconfiguration, Barnes & Jones offers a compact trap thatcan be cleaned and changed by in-house staff rather than bycostly service personnel.

All units are calibrated underoperating (steam) conditionsto provide a trap ensuringaccu rate, consistentlyreproducible actuation at apre-determined temperatu re.
