FUNKE Gasketed and Brazed Plate Heat Exchangers

Gasketed Plate Heat Exchangers Series

As a leader in the industry, FUNKE knows how important it is to constantly be innovating new ways to improve. Their gasketed plate heat exchangers (PHE) do exactly that, with a new form of CFD-optimized embossing and incredible features like a bypass stop system. This series’ new design makes these machines more compact and much cheaper, whether you choose the standard design or the double-wall plate design.

The models in this series include thermally, hydraulically optimized heat transfer plates designed to replace earlier, similar models. You may experience up to 20% improvement in pressure loss and heat transfer efficiency, and these machines feature the same nominal connection diameters for DN 25 to DN 500. You’ll have options like:

• FP2000: An updated version of the series FP10, FP16 and FP22.
• FP4000: An updated version of the series FP206, FP31, FP40, FP50 and FP71.

Explore the Plate Heat Exchanger Up Close

Plate heat exchangers have a very complex design to ensure that media can pass through them safely and complete the heat exchange properly. This diagram shows you how many parts go into the exchanger. This diagram can also be helpful when you need to perform maintenance and part replacements on the PHE.

FUNKE PHEs make the best of both worlds with their “Off-Set” corrugation, creating asymmetrical flow gaps that allow for good heat transfer and pressure when necessary. This special configuration also allows you to adjust the size of the cold and warm PHE sides up to ⅓ of their total capacity.

The Power of Double-Wall Plates

Another enhancement of FUNKE PHEs is their double-wall plate construction. This structure is part of the maximum safety design, as it prevents media from mixing in places where it shouldn’t. With laser-welded plates, the liquids can escape out the plate pair’s edges to prevent contamination in case a leak occurs.

Plate and Gasket Overview

Be sure to take a close look at the thermodynamic design of these plates, which gives you their extreme heat transfer rates. In this diagram, you can see:

1. The “Off-Set” design that provides you with both symmetrical and asymmetrical flow gaps.
2. Carefully made fields of entry for the best media distribution.
3. Gaskets that allow for better maintenance access using a clip system and have a ribbed surface to better stabilize the plate pack.
4. Leakage grooves along the double gaskets to prevent media mixing.
5. Enhanced plate pack reinforcement, which translates to high-pressure resistance during operation.

Data and Materials

Every FUNKE PHE can be customized to suit your industry’s particular operational needs. Below are some of the technical alterations we can make so that your PHE does everything you need it to.

Plate Material

Standard FUNKE plates are made using 1.4404 / AISI 316L, chosen for its ability to resist chemical corrosion and stand up against various media types for a long time. Other plate materials you may decide will work better for you include:

• Alloy C276: Ideal for working with media similar to concentrated sulphuric acid.
• 1.4301 / AISI 304: A more cost-effective choice for operations that do not use critical media.
• 1.4539 / AISI 904L: Has a higher nickel content and provides good performance for its price when working with low-acid, low-chloride media.
• 1.4547 / 254 SMO: For operations that deal with highly corrosive media, this material is even more resistant than our standard material.
• Titanium ASTM B265 Grade 1: Provides even more durability against corrosive media.
• Titanium-Palladium ASTM B265 Grade 11: The highest level of corrosion resistance. It’s the only choice for working with chlorides and highly corrosive media at high temperatures.

Gasketing

Gaskets for these PHEs come in adhesive and nonadhesive forms, and the material mostly depends on the series you choose. Other materials may be available when requested, but the most common gasket materials are:

• Nitrile rubber (NBR): The best choice for all water- and oil-related applications.
• Ethylene-propylene-rubber (EPDM): Good for water and steam applications, as well as working with chemical compounds that don’t use mineral oil or grease.
• Fluororubber (Viton): The choice for working with corrosive materials at high temperatures.

Connections

You may need specific connections to make your PHE work with your existing setup. We offer all common connection types and materials, including:

• Threaded or flange connections
• Loose flange connections
• Molded rubber parts
• Metal linings

If you have another connection type in mind, contact us to see if it’s available.

Special Equipment

In certain cases, these additions to your PHE may be useful in your applications:

• Stainless steel cladding and frames
• A switch-over valve and thermostat so your PHE can also function as a double cooler

Accessories

Other accessories you may find useful include:

• Insulation
• Shroud trays or drip trays
• Resistant paint coatings
• Inline filters
• CIP cleaning systems
• Earthing lugs
