Shell-and-tube heat-exchangers with built-in condensate cooler
- Category: High-efficiency tubular heat exchangers
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
