Product Description

The ‘Swarg Systems & Instruments’ unit consists of a copper tube inside a G. I. pipe. The hot fluid is hot water obtained from a water heater, which flows through the inner tube and cold fluid i.e. cold water flows through outer tubes. The hot water flows always in one direction while direction of cold water can be changed parallel or counter to hot water so that unit can be operated as parallel or counter flow heat exchanger. The temperature and flow rate of water are measured and heat transfer rate, LMTD, heat transfer coefficients and effectiveness of heat exchanger can be calculated.
