ISCAR, A World Leader in the Renewable Energies Industry Renewable Energy is collected from clean resources that are naturally replenished on a human time scale such as sunlight, wind, rain, tides, waves, and geothermal heat. Hydro Power is power derived from the energy of falling water or fast running water, which can be harnessed for useful purposes. ISCAR, a company with many years of experience in the production of metal cutting tools, offers unique solutions for the new generation of industries. As a leader in providing productive and cost effective machining solutions, ISCAR strives to be up to date with all the new trends and technologies which are a part of a brighter, greener future. A heat exchanger is a system used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing, or they may be in direct contact. Both gasses and fluids can be transferred through heat exchangers. There are three main types of heat exchangers; shell & tube, plate & frame, and air-cooled. Heat exchangers are critical in modern industries such as automotive, aerospace, and power. Many engineering resources are required to create optimal heat exchanging solutions for industrial demands. Advanced designs of heat exchangers are examined by using finite element methods. ISCAR has developed a range of full solutions for the production of heat exchangers for drilling, turning, milling, and grooving operations.
