HB Products Receives DKK 2.5 Million in EUDP Support

HB Products A/S, based in Hasselager, has received a grant of DKK 2.5 million from Energiteknologisk Udviklings- og Demonstrationsprogram (EUDP) (Energy Technology Development and Demonstration Programme). The project will be carried out in cooperation with the Danish Technological Institute as well as international component suppliers within industrial refrigeration, including Alfa Laval and Grundfos.

Market-driven project – technology that has been in demand for over 50 years
The project is based on a patent-pending sensor technology for effective control of industrial refrigeration systems. The sensor, which was introduced at the Chillventa trade fair in 2012, has been in demand on the market for over 50 years. It is the only sensor in the world capable of measuring the relationship between gas and liquid in a refrigeration system. Since an industrial refrigeration system is made up of more than just this sensor, the other components in the system must be adapted to the new technology. These components include pumps, condensers, and heat exchangers.

The sensor is based on the capacitive measuring principle, and it measures the gas quality as wet/dry at the outlet/suction pipe in an evaporator. The sensor measures the degree of dryness "X" of the gas, and the value is converted into a 4-20 mA analogue signal.

Substantial energy savings are expected
EUPD has approved the project since substantial energy savings can be achieved by using the sensor. The project is therefore driven by the political agenda of lowering CO2 and CO2 equivalents in the atmosphere, as well as generally improving the effectiveness of the refrigeration process.

The refrigeration design of the future
The energy savings and other advantages of using the new sensor technology are expected to revolutionise the refrigeration industry over a number of years. There is therefore great business potential for HB Products A/S and the other project participants. Particularly in USA, where contrary to Europe there exists legislation regulating the degree of filling of a refrigeration system, the technology has been met with great interest.

Project title: Development, testing, and commercialisation of a new sensor principle for refrigeration systems.

Total budget:
DKK 5.0 million

DKK 2.5 million

Project period:
01.08.2013 - 01.11.2015

Project participants:
Danish Technological Institute, Alfa Laval A/S, Grundfos A/S, Thermofin GmbH, J.H. Development ApS and S.V.K. Energi A/S. Project participants include manufacturers, suppliers, and users of refrigeration systems.

Project interests: Hadsten Technical School & Johnsons Controls Cooling Technology Division in Hornslet - Denmark.

Technology: The sensor enables the operation of a refrigeration system as a DX system (Direct Expansion). In addition to the substantial energy savings, the advantage of the sensor principle is a lower degree of filling of refrigerant in the system. A reduction in refrigerant by a factor of 30-50 is expected.
From a technological design perspective, the sensor technology is also energy efficient, since it is not affected by water in the refrigerant (for ammonia-based systems), nor does it generate any kind of pressure drop in the system. In addition, sensor, an optimum operation of flooded evaporators with forced circulation.

Apart from the sensor, the project also includes the regulation of a refrigeration system. HB Products A/S has introduced a ground-breaking innovation by simplifying and integrating regulation in its sensors.

HB Products A/S: For over 30 years, the company has specialised in the development, manufacture, and sale of sensors for the refrigeration industry. The sensors are found on refrigeration compressors, refrigeration tanks, and in cooling pipes, a particularly harsh environment where low temperatures, high pressure, and corrosive refrigerants put high demands on sensor design. The company sells products globally to large and small players in the industrial refrigeration market.
