The present set-up offers us a comparative study of Jacket & Helical coil, which can be operated simultaneously. It is a stainless steel jacketed vessel with helical coil of copper is fitted inside. A variable speed stirrer is fitted in the vessel. Variation in temperature of inside water is measured and is noted. Set-up is fitted with steam traps for condensate collection. Flow rate of water can be controlled and measured using valve and flow sensor. Temperature of inlet and outlet of both hot & cold fluids are measured by temperature transmitters.
