Industrial line

Alfa Laval Industrial line is an extremely wide range of gasketed plate-and-frame heat exchangers used in all types of industries. The number of sizes, plate and gasket materials and available options are enormous. Every detail is carefully designed to ensure optimal performance, maximum uptime, and easy maintenance.

Versatile design

The Industrial line’s versatility allows it to be designed and configured for applications ranging from relatively simple duties with low requirements to very demanding duties with the highest requirements on both performance and documentation. The products are used for heating, cooling, heat recovery, condensation, and evaporation. 

Equipped with well-designed features, the Industrial line of heat exchangers are easy to maintain and have a long service life. Some of the features available include:

  • ClipGrip™ gasket – a glue free gasket with superior alignment that ensures a perfect seal and trouble-free maintenance.
  • Glued gasket – a two-component, oven-cured epoxy glue keeps the gasket in place during any possible cleaning condition.
  • CurveFlow™ distribution area – ensures full use of the heat transfer area and minimizes fouling.

Additionally, the pressure plate roller, the bearing boxes on the tightening bolts, and the 5 point alignment system with reinforced hangers make opening and closing the heat exchanger quick and easy without the need for heavy tools or the risk of damaging the plates.

Alfa Laval Industrial line is quick and easy to modify if process parameters change. Our team’s expertise and the availability of parts bring you peace of mind.

Plate types for different needs

Industrial line is available with four different plate configurations:

  • Single plate with a chevron pattern design for parallel flow allows for optimum thermal performance and pressure drop.
  • Single plate with a chevron pattern design for diagonal flow allows for optimum thermal performance through the heat exchanger when it is mounted horizontally and requires complete drainability.
  • Double wall plate is used when extra care is needed to avoid mixing fluids.
  • Gemini double wall plate is used when extra care is needed to avoid mixing fluids in hygienic applications.

 

Benefits

  • High energy efficiency
  • Flexible configuration
  • Easy to install
  • High serviceability 
  • Small footprint
  • Access to Alfa Laval’s global service network

How it works

The heat transfer area of a gasketed plate-and-frame heat exchanger consists of a series of corrugated plates, assembled between the frame and pressure plates, which retain the design pressure. The sealing between the plates is made of gaskets. For the highest thermal performance and to enable a very close temperature approach, fluids normally run counter-currently through the heat exchanger.

The Industrial line is available with various pressing depths and angles of the chevron pattern and various shapes of the corrugation which are all carefully designed and selected to achieve optimal performance. The CurveFlow  and the chocolate pattern distribution area are two design features available that ensure fluids are evenly distributed across the entire plate.  The result is that the entire heat transfer surface is fully utilized and stagnant zones that can result in fouling are avoided.

High flow turbulence between plates results in higher heat transfer; however, the consequence is pressure drop. Our thermal design engineers will help you design and select the model and configuration that is suitable for your application needs while delivering maximum thermal performance and minimizing pressure drop.

Features that matter

It's important to understand that all gasketed plate heat exchangers are not the same. The features highlighted below are important components to look for in a GPHE, and when combined, these features offer extensive benefits, such as reduced total cost of ownership, higher efficiency and increased staff safety.

Swing feet

What are they?

Swing feet can simply be swung to the side for service, allowing for quick and easy opening of the unit while maintaining its seismic rating.

Risks with other designs

Most plate heat exchangers have feet that are bolted or welded to the frame and/or pressure plate. These feet are more likely to get stuck, and they also have to be completely removed for servicing. 

Distribution area - CurveFlow

What is it?

One of the most important features of a plate heat exchanger, the distribution area ensures full use of the heat transfer area and minimizes fouling.

Risks with other designs

An inefficient distribution area with uneven flow causes maldistrubution and fouling build up.

ClipGrip gasket

What is it?

A glue free gasket with superior alignment that ensures a perfect seal and trouble-free maintenance. Fastening to the plate is improved by having five fastening points.

Risks with other designs

Other gasket designs, such as snap-in gaskets, only have one fastening point to the plate. If this one point is lost, there is no gasket fastening function.

Alignment system - corner guiding

What is it?

Corner guiding keeps plates aligned thoughout the entire plate package during closing of the heat exchanger. The plates are designed with corners that lead the plates into position and help stabilize the plate pack during the tightening procedure.

Risks with other designs

The lack of a proper alignment system may allow the plate pack to move in any direction, leading to wavy plate packs with leakage problems.

Pressure plate roller

What is it?

The pressure plate must be easy to move and slide along the carrying bar in order to gain access to the plate pack. The most common solution is a roller on top of the carrying bar, making it easy and less time consuming to conduct service. The roller should be made out of metal to be able to carry the weight of the pressure plate.

Risks with other designs

The mechanical solution of the roller can be more or less robust. The risk is a pressure plate that is jammed and impossible to move when it is time to conduct service. 

Bearing box

What is it?

A device between the tightening bolt head and the frame that reduces friction forces and makes service easier.

Risks with other designs

Opening and closing the PHE without bearing boxes is time consuming and increases the risk of paint damage, which can lead to corrosion damage.

Five point alignment

What is it?

Keeps the plates aligned during closing of the plate heat exchanger that facilitates service.

Risks with other designs

Many alignment systems do not close the vertical gap between the carrying bar and the plate, leading to wavy plate packs with leaking problems.
