  • Direct and Indirect Heat Transfer GLV

    The direct heat transfer is done by introducing medium pressure steam into the circulation line with direct steam nozzles. No heat exchanger is needed due to the small amout of steam required, and at the same time, heat exchanger cleaning or repairing is eliminated. The indirect heat transfer is done by shell/tube heat exchanger.
