Steam traps help Royal United Hospital Bath secure energy efficiency award 16 October 2012

The Royal United Hospital Bath NHS Trust is reporting that Thermal Energy International's GEM venturi orifice steam traps have helped it reduce emissions by 25% and energy costs by £800,000.

They have also secured the hospital the winning place in the prestigious HSJ Energy Efficiency Award.

TEI supplied the trust, which occupies a 52-acre site near Bath city centre, with 153 GEM traps, installed in installations ranging from space heating to domestic hot water calorifiers.

Beyond the venturi steam traps, the judges praised the hospital for its dedicated approach in reducing carbon footprint, saving money and improving the environment by installing a new combined heat & power (CHP) plant and LED lighting.

The judges said the trust had implemented "a whole system approach in sustainable healthcare, based around delivery of a comprehensive and wide ranging energy efficiency programme".

Instead of utilising a valve mechanism to close off steam, the GEM steam traps use the patented venturi orifice design to drain condensate from the steam system and maximise energy and water conservation.

As they have no moving parts to wedge open or fail, these traps are claimed to provide a permanent solution to steam trapping and condensate return problems.

TEI also says its flue gas condensing heat recovery economisers can reduce energy consumption of an industrial boiler by up to 18%, by capturing the waste heat in the flue stream and converting it to hot water.
