Heat Exchanger

Heat exchangers are used to transfer heat from one medium to another. These media may be a gas, liquid, or a combination of both. The media may be separated by a solid wall to prevent mixing or may be in direct contact. Heat exchangers can improve a system’s energy efficiency by transferring heat from systems where it is not needed to other systems where it can be usefully used.

Another common use of heat exchangers is to pre-heat a cold fluid entering a heated process system using heat from hot fluid exiting the system. This reduces the energy input necessary to heat the incoming fluid to working temperature.

  • Specific applications for heat exchangers include:
  • Heating a cooler fluid using the heat from a hotter fluid
  • Cooling a hot fluid by transferring its heat to a cooler fluid
  • Boiling a liquid using the heat from a hotter fluid
  • Boiling a liquid while condensing a hotter gaseous fluid
  • Condensing a gaseous fluid by means of a cooler fluid

The fluids within heat exchangers typically flow rapidly, to facilitate the transfer of heat through forced convection. This rapid flow results in pressure losses in the fluids. The efficiency of heat exchangers refers to how well they transfer heat relative to the pressure loss they incur. Modern heat exchanger technology minimizes pressure losses while maximizing heat transfer and meeting other design goals like withstanding high fluid pressures, resisting fouling and corrosion, and allowing cleaning and repairs.

To utilize heat exchangers efficiently in a multi-process facility, heat flows should be considered at a systems level, for example via ‘pinch analysis’ [Insert link to Pinch Analysis page].  Special software exists to facilitate this type of analysis, and to identify and avoid situations likely to exacerbate heat exchanger fouling

Brazed Plate Heat Exchanger

Brazed plate heat exchangers are one of the most efficient ways to transfer heat. They are designed to provide unparalleled performance with the lowest life-cycle cost. Choosing brazed technology for your next heating or cooling project will bring many benefits, including savings in space, energy, and maintenance.

A Brazed Plate Heat Exchanger (BPHE) offers the highest level of thermal efficiency and durability in a compact, low-cost unit. The compact BPHE is constructed as a plate package of corrugated channel plates with a filler material between each plate. During the vacuum brazing process, the filler material forms a brazed joint at every contact point between the plates, creating complex channels. The BPHE allows media at different temperatures to come into close proximity, separated only by channel plates that enable heat from one media to be transferred to the other with very high efficiency.

The flexibility of our BPHEs makes them an excellent choice for many applications. The wide range of plate sizes, plate pattern combinations and connections enables a virtually unlimited number of combinations.

Compact

Our BPHEs are extremely compact compared with other technologies. The footprint can be as little as one tenth that of a shell & tube heat exchanger or half that of a gasket PHE.

Efficient

With no need for gaskets or supporting equipment, about 95% of the material is used to transfer heat. The highly turbulent flow also enables you to use small temperature differences efficiently.

Reliable

The robust construction requires no gaskets, eliminating their risk of leaking. This means stable thermal and hydraulic performance, with minimal maintenance and operational downtime.

Flexible

The compact size uses space efficiently and makes system design more flexible. Larger installations can be constructed unit by unit via standard doors and elevators, and it is easy to expand capacity when demand increases.

Cost-effective

You will save on energy, maintenance, spare parts, and installation. The life-cycle cost over 15-20 years can often be half that of a corresponding gasketed solution.

Self-cleaning

Our BPHEs are normally self-cleaning, thanks to highly turbulent flows. In applications with a high risk of fouling or scaling, Cleaning in Place is easy without disassembly.

Customized

By combining plate design, materials, and connections from standard components, we keep lead times short while still maximizing output in your specific application.
