1 The Dolphin Heat Transfer The leader of the heat transfer industry We offer a wide range of precisely engineered Heat Exchangers and Cooling Systems that help in meeting various performances and allied requirements. Dolphin Heat Transfer

2 We specialize in thermal management systems and components covering a wide range of material technologies including cu/brass, aluminum and CuproBraze. T Dolphin Manufacturing Line designs and manufactures high value-added, technology-based thermal management products and services for the commercial vehicle, off-highway, HVAC/R and rail industry. We offer a highly v range of both pre-engineered and custom-made heat exchangers and ONE OF THE WIDEST PRODUCT RANGE The product range of Dolphin is one of the widest in this industry. Besides designing and manufacturing heat exchangers and engine cooling components we provide a comprehensive r oper OPTIMIZED PRODUCT DEVELOPMENT CYCLE We have a state of art material, thermal and structur evelopment cy

3 We design and manufacture products for multiple segments and markets including: Automotive, medium and heavy-duty commercial vehicles Off-highway and industrial equipment Railway segment Heating, ventilation and air conditioning equipment

4 Brazed Aluminum Technology ves require large heat exchangers for cooling the electrical transformers and inverters that convert the high voltage electricity from the transmission lines into the lower voltage, higher amperage electricity necessary be removed. Electric equipment requiring cooling technology are as example transformers, converters, electric drive motors and power electronics. ALUMINUM MATERIAL TECHNOLOGIES Aluminum material technologies we use are Plate & Bar, Tube-to-Fin and Microchannel (MCHX) types providing: Tube-to-Fin and Microchannel technologies enable light weight Plate & Bar pressure up to bars.

5 Radiators, charge-air-coolers, fuel coolers, oil coolers and HVAC/R units Low noise levels Very versatile technologies for custom-made cooling systems enabling optimization of anti-clogging and ease of cleaning Plate & Bar Core Surface coating technologies for enhanced corrosion resistance ,8 Heat Transfer in Kcal/hr Pressure drop in Kpa 0,6 0,4 0, Water Flow Rate in LPM Water Flow Rate in LPM Windtunnel test is used to measure and optimize the performance of the cooling modules and systems.

6 Copper-Brass and CuproBraze Manufacturing Technologies Dolphin Manufacturing Line offers both soldered copper-brass and brazed copper-brass CuproBraze heat exchangers for mobile and industrial applic ons. SOLDERED COPPER-BRASS TECHNOLOGY Soldered copper-brass technology is a v v avy diesel reparability. High nobility of copper and brass alloys ensures good resistance against general corrosion and stress corrosion cracking (SCC). CuproBraze oys with the temperatures. reliability and ex even at the harshest oper r n drag and superior heat tr to-volume r exchanger. This ensures that product design engineers do not need to make any compromises with respect to cooling system weight, cost, size and durability.

7 CUPROBRAZE THE TECHNOLOGY OF CHOICE FOR FUTURE GENERATIONS OF HEAT EXCHANGERS CuproBraze is a heat exchanger manufacturing technology for industrial and mobile heat exchangers. CuproBraze heat exchangers are made using special anneal-resistant alloys of copper and brass. F resistances of CuproBraze: 1. Resistance to elevated temperatures and pressures Resistance to corrosion These three resistances add up to durability, reliability and long service life for CuproBraze heat exchangers and, consequently highwa ves. The excellent corrosion resistance of CuproBraze products is due in part to the Using high copper content brass alloy for tubescuprobraze material technology ensures excellent resistance against internal corrosion caused by low quality of coolants. In a world that is increasingly concerned with service life, recycling, reparability and sustainability, a premium is placed on the durability of components. The excellent durability of CuproBraze has been proven not only through accelerated experience. 3D-vibr exchangers combined with other structur technologies enables to ensure oper
