R & D TEST FACILITIES | Welcome To Dolphin



Dolphin’s New state of the art Research and Development facility is equipped and designed to establish the fundamental thermodynamic characteristics of any heat exchanger and to assess product performance under a wide range of operating conditions. Dolphin’s State of the art Wind Tunnel can be utilized as a tool to validate the thermal design including pressure drop, heat dissipation, heat absorption and thermal characteristics of any material. It is also used to identify quality related problems from manufacturing operations and the critical points in any heat exchanger.The new facility is being used for product validation and performance verification of their engineering designs and products as well as prototypes. This new facility includes a state of the art Wind Tunnel, 3 Dimensional Vibration Test Rig with 8 individual probes for SWAAT and Thermal Shock tests. All test equipment’s are procured from world renowned suppliers.The wind tunnel is able to conduct thermal performance characteristic tests for automotive, mining, marine, construction, locomotive, HVAC and industrial cooling system products. The Wind tunnel provides accurate readings measured by a digital device and controlled by their Lab view software. The special advantage of this climatic control wind tunnel rig is that it can maintain heat balance within 5%.

The new wind tunnel was designed to Dolphin’s specifications and manufactured by M/S Thermodyne Engineering Ltd, Canada and uses a powerful 7HP blower fan. It consists of air heater, steam generator and chiller to vary air temperature from 68 ° F and humidity from 50 %. Its air velocity is controlled by ASME elliptical nozzle from 0.1 m/sec

These tests can be carried out for following the products

  • Radiator
  • Oil Cooler
  • Condenser
  • Charge Air Cooler
  • Chilled Water Coil
