Redeem focuses on research and development and licences its innovative solutions to enable third parties to develop environmentally friendly products and services that meet the urgent environmental challenges of our time. Bernard Killingbeck, Chief Technical Officer, is the driving force behind this.

"Cooling is crucial to modern life, but it comes at a significant environmental cost. Accounting for 20% of global electricity consumption, cooling generates more than twice as many carbon emissions as shipping and aviation combined. As the demand for cooling continues to grow, it is crucial to develop more sustainable solutions. At Redeem Technologies, we are committed to meeting this challenge by revolutionising refrigeration with energy-efficient, environmentally friendly technology."

Cost efficiency

Redeem's technology reduces the energy required for cooling by up to 30%, thereby lowering operating costs, conserving natural resources and reducing carbon emissions. The company is currently focussing on applying the new technology to heat pumps and transcritical CO2 cooling. The company is also beginning to look at other areas such as carbon capture and storage and pneumatic propulsion.

"Importantly, our technology is scalable so that it is suitable for a wide range of environments and industries," says Bernard. "This allows our licensing partners to develop customised solutions that meet the specific needs of their customers while maximising environmental benefits."

"Our test benches must be easy to set up and operate, and the data acquisition must be reliable," he explains. "A lot of our research involves comparing the torque input with the speed, power or work done. The discovery of TorqSense from Sensor Technology was a godsend, as it is easy to set up and completely reliable, even in long-term tests. We now use TorqSense consistently in all laboratory testing of drive systems."

At Redeem's headquarters at the Hethel Engineering Centre in Norfolk, prototypes are subjected to long-term evaluation on bespoke test rigs, with large amounts of data being collected and analysed. Sensor Technology offers two ranges of sensors: SGR, which is based on a full four-element strain gauge bridge, and the ORT optical range. Both are available in a variety of sizes and both are non-contact and not hard-wired, resulting in sensitive and unreliable slip rings.

"In an intensive test environment, the time saved by not having to set up slip rings for every test quickly multiplies into a significant productivity gain," notes Bernard, "while TorqSense's reliable data capture means that every test produces a near-perfect data set."

TorqSense is designed to fulfil both user requirements. In particular, the new devices are able to accurately record transient torque peaks, which are often important indicators for test engineers of developing problems that can be rectified at an early stage. TorqSense devices automatically compensate for any external forces, such as bending moments, that inadvertently act on the sensor. They also offer high sensitivity, have a large temperature tolerance, do not suffer from the signal distortion that occurs with slip rings and hard-wired solutions and have a mechanical overload capacity of 400 %.
