What Are The Different Types of Plate Heat Exchangers
Plate Heat Exchangers include gasketed, brazed, welded, semi-welded, shell and plate, and specialty types for varied industrial uses.
More
A fermentation cooling heat exchanger is a thermal device that transfers heat from the fermenting liquid (wort, mash, or broth) to a cooling medium—typically chilled water, glycol, or brine. Without effective cooling, exothermic reactions can raise temperatures beyond the tolerance of yeast or bacteria, leading to off-flavors, reduced yields, or batch failure.
Plate heat exchangers have become the preferred solution because they offer high heat transfer coefficients in a compact footprint. Compared to shell-and-tube units, plate designs reduce approach temperatures and allow easier cleaning. For fermentation duty, both gasketed and fully welded plate exchangers are widely used, depending on pressure, temperature, and media compatibility.
In a typical setup, the hot fermentation broth flows on one side of the plate pack, while the coolant flows counter-currently on the other side. The corrugated plate pattern creates turbulence, which significantly enhances heat transfer. The exchanger can be installed as a side-stream loop, where broth is continuously pumped through the unit and back to the fermenter, or as a direct jacket-integrated design.
Key process parameters include:
SHPHE offers free thermal design and selection service to match these parameters precisely, ensuring the right plate count, channel arrangement, and material choice.
When selecting a heat exchanger for fermentation duty, engineers should evaluate the following features:
SHPHE’s product lines—including TP Welded Plate Heat Exchangers and Gasketed Plate Heat Exchangers—offer these features with ISO9001 and ASME U certification.
Fermentation cooling heat exchangers are used across multiple industries:
For each application, SHPHE recommends a specific plate type. For example, the Wide Gap Welded Plate Heat Exchanger is ideal for media with suspended solids, while the HT-Bloc Welded Plate Heat Exchanger suits high-temperature or high-pressure duties.
SHPHE is a Shanghai-based plate heat exchanger manufacturer founded in 2005, exporting to more than 20 countries. The company holds ISO9001 and ASME U certifications, ensuring every unit meets international quality standards. SHPHE’s product portfolio includes:
SHPHE offers free thermal design and selection service, helping buyers specify the correct plate material, gasket type, and channel configuration. The company’s exchangers are compatible with major brands such as Alfa Laval, Compabloc, and GEA, making them a reliable alternative for retrofit or new installations.
For fermentation cooling, SHPHE’s custom-engineered pillow plates can also be used as internal fermenter cooling panels, providing direct heat transfer without an external loop.
Yes, but only if the broth is free of large particles. Yeast cells (5–10 µm) pass through standard plate gaps without issue. For broths containing hops, grain husks, or other solids, a wide gap welded plate exchanger is recommended to prevent clogging and reduce cleaning frequency.
A well-designed plate exchanger can achieve a temperature approach of 2–5 °C between the broth outlet and coolant inlet. For example, if coolant enters at 4 °C, the broth can be cooled to 6–9 °C. Closer approaches require more plates and higher pressure drop.
Cleaning frequency depends on broth composition and operating hours. In breweries, CIP (clean-in-place) is typically performed every 1–2 weeks. For bioethanol plants with continuous operation, monthly cleaning is common. Gasketed units allow easy plate access for mechanical cleaning, while welded units rely on chemical CIP.
It depends on the application. Fully welded exchangers eliminate gasket leaks and can handle higher pressures and temperatures, making them suitable for sterile processes. Gasketed units are easier to clean and expand, and they cost less initially. For most brewery applications, gasketed designs are sufficient; for pharmaceutical or high-pressure bioethanol, welded is preferred.
316L stainless steel is the standard for fermentation due to its corrosion resistance and cleanability. For aggressive media or high chloride content, 904L or titanium may be specified. Gaskets are typically EPDM (for water/glycol) or HNBR (for higher temperature or oil-containing media).
Yes, SHPHE designs replacement plate packs and complete units that are compatible with major brands. The company uses the same port centers, plate patterns, and gasket profiles to ensure drop-in replacement without piping modifications.

Industrial furnace and boiler exhaust gases carry vast amounts of unutilized thermal energy. The SHPHE custom Plate Air Preheater (PAPH) is target-engineered to intercept this high-temperature flue gas, recovering valuable waste heat and transferring it directly back to incoming combustion air or process gas streams. By substantially elevating the temperature of your flame feed, our custom systems optimize combustion thermodynamics, deliver massive fuel savings, and significantly reduce industrial carbon and emissions footprints. Built to withstand severe flue-gas environments, SHPHE PAPH systems serve as the premier choice for modern, energy-intensive plants prioritizing decarb compliance and maximum thermal efficiency.
The SHPHE Printed Circuit Heat Exchanger (PCHE) represents a paradigm shift in microchannel thermal management, meticulously engineered for the world's most critical and demanding industrial boundaries. Developed to surpass the physical limitations of conventional shell-and-tube designs in ultra-high-pressure environments, our custom PCHEs integrate advanced photochemical etching and solid-state diffusion bonding to provide unmatched safety, thermal efficiency, and integrity under extreme stress. Initially deployed within high-consequence sectors such as aerospace and nuclear power generation, PCHE technology has completely revolutionized high-density thermal processing. Today, SHPHE brings this breakthrough engineering to mainstream energy transitions—including LNG liquefaction, supercritical CO² power cycles, hydrocarbon processing, and high-pressure hydrogen systems—enabling plants to maximize energy recovery, ensure zero-leakage security, and significantly shrink environmental footprints.

Brewery Operations ManagerWe’ve been using this cooling heat exchanger for our lager fermentation tanks for about three months now. The temperature control is spot-on—no more hot spots or sluggish ferments. Cleans up way easier than our old plate unit. Absolutely worth the investment for any mid-sized brewery.

Fermentation ScientistI was skeptical about switching from a glycol jacket setup, but this exchanger integrates seamlessly with our existing loop. The cooling capacity is impressive for its footprint. Only gave 4 stars because the gaskets took a bit of fiddling to seat perfectly on installation day. Otherwise, solid performance for precision work.

Head DistillerRunning a small craft distillery means every piece of gear has to pull double duty. This heat exchanger handles our wash fermentation cooling like a champ and doesn’t clog up with solids like the old shell-and-tube did. The stainless build feels bombproof. Highly recommend for anyone doing grain-to-glass.

Plant EngineerWe retrofitted this into a dairy fermentation line that was overheating during summer peaks. It dropped our cooling time by nearly 30% compared to the previous setup. Very low pressure drop, which our pumps appreciate. Two months in, zero leaks or fouling issues. Solid engineering.
