EGAT also ipleented an air conditioning cold storage and crop dryer syste using exhausted hot water. Husavik (iceland) Lansvirkjun Recurrent Engineering 1 X 2 MW Kalina 2000 This is one of the few Kalina cycle power plants in the world. The working fluid is an aonia/water ix. Krafla (Iceland) Lansvirkjun MHI 2 X 30 MW Large-scale volcanic eruptions only 2k fro the site were an early proble during construction. In 1996, a decision was ade to install a second T/G set and borehole drilling with iproved technology began iediately. 33 boreholes have now been drilled for the Krafla station and, on average, about half are used at any tie.this is one of the few Kalina cycle power plants in the world.
