FUNKE Gasketed Frame and Plate Heat Exchangers

funke gasketed heat exchanger side

Fluid Aire Dynamics’s inventory of FUNKE gasketed heat plate exchangers (PHEs) features a number of compact, single and multipass PHEs. Despite their smaller-than-average size, these PHEs yield ample power thanks to heat exchange surfaces of up to 2,000 m².

What makes these PHEs the best choice for your company’s needs? Aside from a unique design of highly intricate embossing, these machines are easily customizable to fit your material, cost and performance desires. Our team wants you to be able to achieve all your business goals, and we know you need the best machinery available and reliable support options to meet productivity objectives. We’re here to offer you both in a convenient package so you can get back to work today.

Welcome to the FP Series

FUNKE’s gasketed PHEs use adjoining embossed plates with apertures. Gaskets are glued or secured to each plate so that when the plates are arranged at 180° angles from one another, the spaces create a flow gap that is sealed securely, preventing media mixing and outside interference in the heat exchange process.

This entire assembly gets mounted and compressed within a frame that features a fixed plate and a moveable plate. Altogether, this creates a machine that can efficiently transfer heat between media.

As with all machinery, over time, your PHE will require some maintenance. Luckily, these measures are generally easy, and you won’t have to replace parts often to keep your unit in service. Most commonly, any issue with these parts involves the loosening of bolts and gaskets, which can be retightened many times to increase your return on investment.

Build Now, Expand Later

FUNKE frame and plate heat exchangers are ready to help your operations grow alongside your business. When you order a FUNKE PHE from Fluid Aire Dynamics, we’ll discuss your needs so we can determine the number of plates and sizes that you’ll need to complete your work without spending more than you need to. You can feel confident in getting a PHE that fits your current needs, because the moment you want to expand, we’ll come right back to help you do so.

One of the biggest benefits of these plate heat exchangers is that you can add plates and build extensions right onto the original machine without affecting its performance. When you’re ready to increase your capabilities, all it takes is a few additions and reinstallations for you to expand your capabilities and get back to production.

Benefits of FUNKE PHEs

FUNKE frame and plate heat exchangers come with many capabilities you won’t find with other models and brands. Some of the most standout additions include:

  • High thermal conductivity
  • Highly efficient self-cleaning
  • Unique FUNKE “Off-Set” design
  • Optical gasket identification (color-coding)
  • Compact design
  • Highly flexible (upgrade/downgrade)
  • Ease of service and maintenance
  • Modular systems for short production times
  • Tiered plate guiding bar (easier plate installation)
  • Many connection options

Connecting your machine to other parts of your setup can be challenging when the connections don’t line up by default. With FUNKE PHEs, you can customize the connectors to fit your needs. We offer all the most common connection types, such as rubber moldings, metal liners, welding neck flanges, tri-clamps, dairy pipes and aseptic.

Technical Data

When considering these PHEs for your operations, consider their maximum specifications to ensure they’ll fit your needs:

  • Heat exchange surface per plate: 0.04 – 3 m²
  • Maximum operating pressure: 25 bar
  • Maximum operating temperature: 200°C

As safety is also one of our top priorities in providing you with new equipment, you’ll find that we offer a number of additional safety features if your operations require them, including:

  • Double gaskets at inlets and outlets to keep media from mixing.
  • Double plates with special gasket systems for PHEs that will be safety heat exchangers.
  • Stainless steel configurations to accommodate pharmaceutical and food safety needs.
  • Plate heat exchangers in a redundant configuration installed as a compact unit on the base frame, including switch-over valve, thermostat and safety valves.

FP2000 Series

The FP2000 Series features DN 50 connections and serves as an upgrade to the FP10, FP16 and FP22 series. Nominal connection diameters allow connections from DN 25 to DN 500, and you’ll have new features like the bypass stop system and CFD-optimized embossing.

FP4000 Series

FUNKE FP 4000 Gasketed Heat Exchanger

With the FP400 series, you’ll have DN 100 connections and nominal connection diameters from DN 25 to DN 500. This series can replace the FP206, FP31, FP40, FP50 and FP71 lines. Benefits of this series include CFD-optimized embossing and the new bypass stop system.

Gasket and Plate Combinations

You’ll find a variety of options in our selection of FUNKE plates and gaskets, letting you find the most cost-effective, compact solutions for your PHE. All of FUNKE’s plates feature embossing that’s been optimized for maximum thermodynamics and hydraulics, regardless of the materials and attachments you choose. Take a look at some of the most common plate and gasket configurations we supply.

PHE Design

This diagram gives you an up-close view of all the parts that make your PHE function, with the numbered components highlighting how many pieces come together to give you a working heat exchange solution. This resource is also helpful for performing occasional maintenance and replacements if you’re interested in completing these yourself. However, when you buy your FUNKE PHEs from Fluid Aire Dynamics, we can take care of the preventative maintenance and repairs for you.

Media Flow Diagrams

Plate heat exchangers usually feature one of two configurations:

  • Single-pass: Single-pass configurations are the more common option. In this case, the outlet and inlet pipes are all connected to the fixed plate, so the media only has to pass through once to complete the heat transfer. A major advantage to this configuration is that taking it apart for servicing is much easier.
  • Multiple-pass: In multiple-pass PHEs, the connection pipes are attached to both the fixed and movable plates, which are on opposite sides of the configuration. Because of that, media has to pass through the plate package more than once to achieve the proper heat transfer. Multiple-pass PHEs are a better option when working with media that only has a slight difference in temperature.

For a visual example of how these configurations differ, take a look at the associated figures.
