Product Description

The ‘Swarg Systems & Instruments’ cross flow heat exchanger is air-to-air type heat exchanger. On both hot and cold sides, air flow is generated by centrifugal blowers. Hot air is obtained by passing air over a bank of finned tubes. The air then flows to heat exchanger section i. e. a bank of finned tubes. Hot air flows through tubes while cold air flows over the tubes at right angle to hot air. The experiments can be conducted over various air flow rates and air temperatures to determine LMTD, heat transfer rates and effectiveness of heat exchanger.
