London-based startup Futraheat has scheduled trials of its prototype high temperature heat pump at a brewery in Sussex. The U.K. government-funded demonstration will test the environmental and energy efficiency benefits of using a low global warming potential refrigerant based on hydrofluoro-olefin technology supplied by Honeywell and Futraheat’s TurboClaw steam compressor.

The electrically powered Greenstream heat pump is designed to help industrial users recycle heat and reduce fuel use by up to 90%. The system incorporates the TurboClaw, a new type of patented turbo compressor, toThe TurboClaw compressor recovers and boosts the temperature of low-grade waste heat for reuse. Source: Futraheat recover low grade waste heat – a by-product of many industrial processes — and boost it up to 150° C for onsite use.

Replacing the brewery’s standard oil boiler with the high temperature heat pump is expected to slash energy consumption, provide fuel cost savings of up to 40% and reduce carbon emissions by up to 100% when the heat pump is powered by renewable energy.

According to Futraheat, the prototype destined for the field trial will be modified to produce low-pressure steam for brewery use. The 300 kW-thermal energy high temperature heat pump will have a temperature input of 100° C and raise this to deliver 130° C for the brewery’s existing malt boiling process.
