Advantages

Brazed-plate heat exchangers have many special features such as:

1. Compact

BPHEs occupy a volume which is extremely smallsometimes down to one-sixth of the space occupied by other types of exchangers. This advantage is especially highly valuable for prefabricated systems.

2. Small Temperature Differences Between Media

With BPHEs, it is possible to work with a very small difference between the condensing and the cooling water temperature. This advantage often makes a great impact on the efficiency of the complete system; for example, smaller compressors.

3. High Working Pressure

The high pressure required on the condensing side of the systems causes no problem to BPHEs. These units are normally tested to a pressure of 40 bar.

4. Low Pressure Drop on

In most cases, the pressure drop in BPHEs is lower than in competing coaxial exchangers.

5. Less Refrigerant Needed

The small internal volume means that the complete system requires small volumes of refrigerant. BPHEs require only one-seventh of the amount of refrigerant compared to systems with conventional exchangers.

6. Lightweight

The compact execution and the small hold-up volume means that the weight is only a fraction of the weight of other exchangers.

7. Low Tendency for Freezing

The high turbulence in the channels minimizes the tendency for freezing on the water side, which means that in evaporation applications the temperature at the water outlet can be lower than in any other heat exchanger type.

8. High Resistance Against Freezing

If there is a failure in the system and the water in the heat exchanger freezes, a brazed-plate heat exchanger can withstand this much better than traditional types and can often continue to work after defrosting. However, no heat exchanger will stand an unlimited number of freezing cycles; and, therefore, necessary equipment for
freeze protection should be built into the system.

9. Modularity

BPHEs can easily be arranged in parallel for systems built on modules.

10. Consistent Quality

The plates of a BPHEs are pressed out of homogenous steel and are brazed together. These plates are pressed with the same tool every time, which guarantees that each plate is identical to the others. This means that the exchanger always performs in exactly the same way. This is an outstanding feature when compared to the many tubular exchangers where great variances in the production might exist.

11. Economical

In most cases, a brazed-plate heat exchanger represents the most economical solution for the customer. This is not only due to the fact that the purchase price of a
brazed-plate heat exchanger is, in most cases, lower than for other types of heat exchangers but also to the fact that the mounting of the unit is easier. Therefore, savings can be made on smaller cabinets, tubing, packing, and freight.
