Possible Improvement Suggestions

  • Use an insulation shell to reduce heat losses and improve energy efficiency.
  • Increase the flow rate while maintaining the temperature difference to achieve higher heat output.
  • Adjust the number of plates to the actual heat demand to optimize pressure drop and material use.
  • Use a heat exchanger with a larger surface area or higher kW rating for high-demand applications.
