The primary markets for the Hiflux heat exchanger are applications where ruggedness, high temperature operation, high performance or compactness is a requirement.
A recuperator is a gas-gas heat exchanger which substantially raises the efficiency of small gas turbines suitable for distributed generation. This is achieved by recovering exhaust heat and using it to preheat the compressed air entering the combustion chamber, thereby reducing the amount of fuel required and correspondingly the emissions. Hiflux technology is designed to operate at higher temperatures and pressures than conventional recuperator technology, offering greater efficiency gains without a reduction in operating life. Recuperated gas turbines remain efficient at part loads typically retaining over 80% of their fully-rated efficiency at 50% of maximum power. Sufficient exhaust heat remains after recuperation for CHP.
Recovering and re-using exhaust heat in the most effective manner is part of the continuous advancement of internal combustion engine technology. Hiflux has participated in a ground-breaking programme to prove the concept of a split-cycle engine which has the potential to raise brake thermal efficiencies to new levels.
Hiflux technology is well suited to the thermal management of power electronics components and electrical assemblies where high heat removal rates are required. Hiflux has participated in a multi-partner funded programme to provide prototype semiconductor heatsinks for a low-carbon vehicle application. Test results show very good heat removal in an ultra-compact package.
Hiflux can manufacture heat exchangers to meet the specific needs of customers with process heat exchange or waste heat recovery requirements. Potential customers in the oil and gas, food and beverage, pharmaceutical, or chemical industries can benefit from Hiflux’s unique technology.
