End users can achieve significant annual energy savings per unit with the BK37-5, which does not consume live steam during operation and can save up to 0.9 kg (2 lb) per hour of steam consumption when compared with TD and inverted bucket steam traps.
“Gestra thermostatic steam traps have revolutionized the European steam trap market, saving companies hundreds of thousands – or even millions – of dollars in energy costs, and it could do the same for the steam trap market in the United States,” said Jeff Drees, President, Flow Control Operations, Flowserve. “Cost reduction has always been a top priority at facilities utilizing steam, and the BK37-5 is competitively priced against thermodynamic disk steam traps while also presenting major opportunities to save on the bottom line by reducing energy consumption.”
The BK37-5 is designed specifically for all pressures from 0.7 to 45 bar (10 to 650 psi) and is suitable for both saturated and superheated steam. Its normally open function allows for automatic air-venting and high-ratio startup, and the trap’s operation is unaffected by pipeline orientation, allowing it to be installed in any position.
The BK37-5 also features the field-proven BK46 regulator, which is not affected by water hammer or ambient conditions and has demonstrated reliability, durability and energy efficiency in harsh environments.   Flowserve Gestra is the global leader in the design and production of thermostatic steam traps, which use changes in temperature to regulate the release of condensate. Steam traps are utilized in virtually every industry, including: oil and gas; chemical processing; food processing; power generation; pulp and paper; and pharmaceuticals.
