New Research & Development facility at Dolphin Manufacturing to develop high performing and premium quality products.

“One Stop Solution for all your cooling needs”

With the ever increasing heat transfer requirements of the industry, it is essential that manufacturers change their way of thinking. The technology and methodologies being used until now have reached their saturation point and there is a strong demand for change. It is this drive for innovation and the need to provide customers with the most efficient product that Dolphin has set up its own Research and Development facility.

The 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%.

“This important investment enables us to evaluate the thermal and fluid-dynamic features of heat exchangers and cooling systems”

 Nooruddin N.J., Chairman.

The new wind tunnel was designed to Dolphin’s individual specifications and manufactured by M/S Thermo dyne 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

Dolphin’s High Frequency Vibration Test Rig is used for conducting strain, fatigue and stress analysis test of heat exchangers to evaluate its structural performance, possible potential failure mode and structural rigidity of heat exchangers which are used in automotive, mining, construction, locomotive and industrial applications. Vibration and shaker tests are used to qualify products during the design process to meet standards, regulatory qualifications. Fatigue testing is used for screening products and evaluating the performance.
