A Funke plate heat exchanger is widely recognized for its compact design, high thermal efficiency, and adaptability to demanding process conditions. In many industrial settings, engineers need equipment that can handle temperature crossovers, viscous fluids, or aggressive media without sacrificing performance. The gasketed and welded plate designs offer flexibility for both low-pressure and high-pressure applications. For those seeking a reliable alternative to original Funke units, SHPHE provides compatible solutions that meet or exceed OEM specifications while reducing lead times and costs.
Plate heat exchangers operate by transferring heat between two fluids through a series of corrugated metal plates. The plates create alternating channels for hot and cold media, maximizing surface area while minimizing footprint. In a typical scenario, a hot process stream enters one side, and a cooling medium flows countercurrently on the other side. The turbulence induced by the plate pattern enhances heat transfer coefficients, often reaching values of 3000–7000 W/m²K for water-to-water applications. This makes them ideal for duties where space is limited and efficiency is paramount.
When evaluating a Funke plate heat exchanger or its equivalent, consider these common specifications found across the industry:
These ranges cover the vast majority of industrial thermal management needs, from food processing to petrochemical plants.
A Funke plate heat exchanger is suitable for a wide variety of sectors. Below are common applications paired with recommended SHPHE product lines:

Our product portfolio includes HT-Bloc and TP welded plate heat exchangers, wide gap welded units, gasketed plate heat exchangers, PCHE, plate air preheaters, and pillow plates. We provide direct alternatives to Funke, Alfa Laval, Compabloc, and GEA designs, with full interchangeability in mounting dimensions and performance. Our engineering team offers free thermal design and selection support, helping you optimize your thermal management system without unnecessary delays.
Yes, SHPHE designs its gasketed and welded plate heat exchangers to be dimensionally compatible with Funke frames. Connection sizes, bolt patterns, and plate pack dimensions match common industry standards, so you can retrofit directly.
Standard units ship within 4–6 weeks. Custom-engineered solutions, such as wide gap or PCHE designs, typically require 8–12 weeks depending on material availability and complexity.
Common gasket options include NBR (for water and oils), EPDM (for acids and alkalis), and Viton (for high-temperature or aggressive chemicals). Provide your fluid composition and temperature range to our team for a precise recommendation.
Welded units require minimal maintenance. Periodic inspection of connections and pressure monitoring is sufficient. For fouling applications, chemical cleaning in place (CIP) can be performed without disassembly.
Absolutely. SHPHE offers free thermal design and selection service. Simply submit your process parameters — flow rates, inlet/outlet temperatures, pressure drop limits, and fluid properties — and we will provide a detailed proposal.
Yes, we hold ISO9001 and ASME U certifications. Our products comply with PED, CE, and other regional standards upon request. Certificates are provided with each shipment.

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.
Since the invention of the plate heat exchanger (PHE) in 1923, thermal technology has evolved from standard food-grade processing to highly complex industrial operations. At SHPHE, we take this classic, versatile design and transform it into highly bespoke heat transfer solutions tailored to your unique process fluids and thermal loads. While traditional gasketed PHEs offer high efficiency and compact footprints, SHPHE optimizes plate corrugations, metallurgy, and sealing systems to handle your specific chemical, HVAC, or energy recovery parameters. Our custom-engineered gasketed plate heat exchangers provide outstanding scalability and ease of maintenance, serving as an indispensable asset for heavy industries—including oil and gas, metallurgy, and food processing—where uptime, energy recovery, and long-term sustainability are top priorities.
Custom-Engineered for Severe Process Demands. At SHPHE, we don't just supply equipment; we design tailored thermal solutions. Our HT-Bloc welded plate heat exchangers are custom-configured by our experienced engineers to overcome your specific industry challenges—whether handling high-viscosity media, extreme temperatures, or strict space constraints.
Custom-Engineered Anti-Clogging Solutions for High-Viscosity Slurries： Deployed specifically to conquer severe industrial fouling, SHPHE wide gap welded plate heat exchangers are tailor-built to handle complex media containing dense fibers, coarse crystals, or solid suspensions without clogging. Each non-obstructed channel is calculated and formed by laser-welded plate packs matching your fluid’s exact rheology and grain size, completely eliminating structural "dead zones" and media stagnation. Available in highly compact vertical and versatile horizontal configurations, our vertical engineering drastically reduces plant footprints while maintaining unhindered product throughput, minimal pressure drops, and flawless continuous operations across harsh process loops.

Linda
Maintenance SupervisorWe swapped out an older model for this Funke plate heat exchanger last quarter. The pressure drop is noticeably lower, and the plates are holding up well even with our slightly aggressive cooling water. No leaks so far, which is a huge win for my sanity. Definitely worth the upgrade.
Tom
Dairy Plant EngineerGot this installed in our pasteurization line. The thing runs smooth and the gasket design seems easier to clean than the old Alfa Laval we had. Only gave it 4 stars because the initial tightening torque specs felt a bit off, but once we dialed it in, it’s been solid. Would buy again.
Diana
HVAC Project ManagerWe needed a compact unit for a retrofit in a downtown office building, and this Funke model fit the bill perfectly. The thermal performance exceeded the spec sheet, and the delivery was surprisingly fast. My installation crew didn't complain once about the connections, and that's a miracle in itself.
Mike
Process EngineerUsing this for a small-scale pharmaceutical batch cooling application. The heat transfer is very consistent, and the titanium plates handle our chloride-rich process fluid without any corrosion issues. Only minor gripe is the frame paint chipped a bit during transport, but functionally it's a beast.
