Shell-and-tube heat-exchangers with built-in condensate cooler

Main advantages of heat-exchangers with built-in condensate cooler:

  • Easy maintenance and operation;
  • Repairability;
  • Very low hydraulic resistance – from 0,25 to 0,45 bar, it allows to use pumps with lower electrical power;
  • Condensate temperature not exceed 90 °С, it allows to use standard condensate pumps made of cast iron or plastic, it is not required to use special stainless steel pumps;
  • Two times reduces work of design and erection companies, because condensate cooler casing is built in heat-exchanger casing;
  • Two times reduces quantity of on-off, control safety valves, level, pressure and temperature gauges.

Disadvantages

  • Has a relatively large size than plate heat-exchanger
