Compact size, higher heat performance

Experience the high thermal performance and improved heat recovery of compact heat exchangers. Small in design, reliable, and cost effective they are a great alternative to standard shell and tube heat exchangers.

From cooling and heating applications to petroleum industries or HVAC processes, heat exchangers are indispensable in our modern society. However, the need to increase thermal performance and heat recovery, while reducing the use of energy and operating costs has become more and more pressing for today’s industrial heat exchange applications.

Finding an industrial heat exchanger that can perform the required heat transfer and minimize size and weight, be resistant to fouling, minimize pressure drops, and be cost effective can be rather hard. Most engineers are used with and trust shell and tube heat exchangers and rarely consider the alternatives. So is there really a high pressure heat exchanger that can achieve the thermal efficiency of a shell and tube design, but in a compact design? It certainly is, and it comes in the form of compact heat exchangers.

Compact heat exchangers

The dominant type of industrial heat exchanger in most process applications today is the shell and tube. As the pressure to reduce both energy usage and CO2 emissions, advances are being made in the range of available designs and operational parameters.

One of the best ways to ensure high performance and heat recovery, with a low cost unit, is by using brazed plate heat exchangers.

Compact heat exchangers are a type of industrial heat exchangers that can incorporate a large amount of heat transfer surface area per unit volume. They are smaller, lighter and less expensive than standard shell and tube heat exchangers, but can offer better quality and longevity. Due to their small volume and weight, they allow for an increased heat transfer rate compared to regular high pressure heat exchanger.

Compact heat exchangers are suited for a large variety of industries and can perform even for the most demanding applications. From oil and water cooling applications to chemical and technical processes of all kinds, compact heat exchangers can be used in a great variety of industries. Small and versatile, they can also be used in modern households which use solar energy for domestic heating.

When to use compact heat exchangers

When it comes to heat transfer processes, maximizing performance, while minimizing energy usage is one of most engineers’ goal. If shell and tube heat exchangers are great for high pressure applications, compact heat exchangers have the advantages of superior heat recovery and higher resistance to fouling.

Compact heat exchangers can be used in a large number of industrial applications, as long as they are able to meet their challenges. They can be a great alternative when the application requires for expensive materials for the heat exchanger, when space is a problem or when heat recovery is important.

Types of compact heat exchangers

There are several types of compact heat exchangers, but the most common ones are the brazed plate heat exchangers and the welded plate heat exchangers. Other types include spiral heat exchangers, plate fin heat exchangers, or compact shell and tube heat exchangers.

Brazed plate heat exchangers

Brazed plate heat exchangers accommodate a set of plates that are brazed together, but without the gasket and frame parts. Manufactured from stainless steel and cooper contained braze, they can operate at higher pressures that gasketed heat exchangers.

Welded plate heat exchangers

Welded heat exchangers accommodate a set of circular plates that are welded together and installed into a pressure shell. Manufactured from rugged materials, such as stainless steel, this heat exchanger can be used to transfer high temperature or corrosive fluids.

Spiral heat exchangers

Spiral heat exchangers consist of two long strips of plate wrapped to form concentric spirals. Made from carbon steel, stainless steel and titanium, they can withstand temperatures of up to 400 °C and pressures of up to 25 bar.

Plate fin heat exchangers

The plate fin heat exchanger is a type of compact heat exchanger which consists of a stack of alternate flat plates and corrugated fins brazed together as a block. Highly efficient and compact, they can withstand pressures of up to 100 bar, depending of the material.

In order to meet the demanding of today’s applications, manufacturers have built smaller and lighter shell and tube heat exchangers, offering the same heat performance.

High heat recovery, low energy usage

One of the main benefits of compact heat exchangers is their compact design. Despite the smaller size, they significantly increase the surface area of the fluids which enables faster heat exchange. As a result, compact heat exchangers can achieve a higher level of efficiency than a standard high pressure heat exchanger.

Another great benefit of compact heat exchangers is that due to the counter-current flow, one single unit can replace several shell and tube heat exchangers. As a result, compact heat exchangers can be less expensive and more energy efficient that standard designs.

In addition to these benefits, the small design of compact heat exchanger makes them a space saving solution.
