Octopus Energi AB

1967 the company Kryotherm www.kryotherm.se is formed in Furulund, Sweden, with a clear business concept ”Simplicity and low maintenance”. At Kryotherm Kurt developed a fundamental idea of recycling the surplus of heat. After some years Kurt left to pursue his new ideas. Today the company is operating in Finland, Norway and England with its head quarters in Piteå, Sweden.

Kurt formed his second company Klimatkyla AB, it made big heat pump installations to industry and warehouse for example IKEA in Köping, Copenhagen and Oslo. In the seventies Euroc Development AB bought Klimatkyla AB and changed the name to Technoterm. Kurt was a part of the deal and was employed as an inventor within Euroc Development AB. During his time at Euroc he worked with for example sun collectors, heat pump technology combined with the sterling engine and making electricity from manure.
After a while at Euroc Kurt leaves to pursue his new ideas once again, this is the beginning of Octopus Energi AB. The name octopus is taken as it best illustrates the many ways of catching energy.

1980 Kurt further develops his thoughts, one of the results is a ground water heat pump with a PEL tube evaporator. This product is patented in seventeen countries. Today it is manufactured and sold by JMC Energi AB.

Two years later the precursor of the Ice-Stick is developed. It was a 600 meter long tube heat exchanger containing 200 liter 33 percent alcohol. Many of these heat pumps are still operating after 22 years (2006-01-28).

Some problems as bringing 200 liter alcohol solution at every installation and continually having to control the alcohol solutions protection from freezing where overcome by the developing of the air fan evaporator with direct expansion.

1991 the air fan evaporator is replaced by the Ice-Stick. The Ice-Stick didn’t need bought energy to defrost and the sound of the fan disappeared. In the Ice-Stick Freon was replaced with Gasol (propane), a more environmental useable gas.

Kurt Karlsson This is the story about a man with ideas long before his time. A man who’s creativeness and curiosity resulted in many exciting solutions.
Kurt Karlsson is still called the”Father of the Heat pump” by people from the old days. His early thoughts and ideas are still fundamental in the business today. Kurt’s ideas of saving energy are as topical today as they where in the sixties, when it was groundbreaking and largely unexplored territory. The story starts when Kurt left school after eight years and started selling freezers and refrigerators to stores. His thoughts began when he saw the waste of heat, in those days they just blew out the heat into the air outdoor, he asked himself “there most by an easier way to recycle the lost energy and at the same time lower the cost of heating the store?” Certainly this could be done, thus the adventures of Kurt Karlsson began.
