Deploying certified thermodynamic engineering configurations optimized for Central European operating climates, low-temperature grids, and rigorous environmental compliance.
Founded in 1995 as Flotte Thermal Engineering and restructured in 2013 with a registered capital of 101 million RMB, Flotte has evolved into a global leader in high-performance fluid control and thermodynamic equipment. Operating out of our modern 70,000 m² production facility, we engineer next-generation plate heat exchangers, industrial plate coolers, and intelligent HVAC control units.
Our commitment to technical rigor is supported by a comprehensive IP portfolio, including patents for "High-Efficiency Plate Heat Exchangers," "Intelligent Plate Heat Exchanger Systems," and "Scale-Resistant Plate Cooler Assemblies." Serving municipal utilities and industrial factories across the Czech Republic, we bridge the gap between large-scale manufacturing and localized, project-specific engineering requirements.
The Czech Republic is one of the most industrialized nations in the European Union, with key economic pillars including automotive manufacturing (centered around major manufacturing hubs), metallurgy (Ostrava region), chemical production (Ústí nad Labem region), and mechanical engineering. Achieving carbon neutrality targets by 2050 requires substantial modifications in process heating and cooling technologies.
A major focus is the modernization of Czech district heating systems (CZT - Centrální zásobování teplem), which serve over 1.6 million Czech households. The phase-out of coal-fired combined heat and power (CHP) plants is forcing a transition toward municipal solid waste (ZEVO), biomass, industrial waste heat recovery, and large-scale heat pumps. This shift from steam-based distribution to low-temperature district heating (LTDH) demands extremely efficient plate heat exchangers capable of handling tight temperature approaches with minimal pressure drop.
Flotte's plate cooler solutions are engineered to support this modernization, offering modular thermal exchange stations, high-efficiency gaskets, and smart monitoring systems that ensure compliance with EU Ecodesign rules and national emissions standards.
Integrating fluid dynamics, metallurgy, and digital controls to provide reliable and efficient process cooling.
Our plates feature optimized chevron patterns. This geometry promotes high turbulence at low fluid velocities, maximizing heat transfer rates while reducing scale build-up in demanding process environments.
We source high-grade alloys, including AISI 304, AISI 316L, Titanium Gr.1, and Hastelloy C-276. This selection ensures durability and corrosion resistance when processing aggressive chemical media or high-chloride municipal water.
Integrated with balancing valves, frequency-controlled pumps, and high-precision temperature collectors, our units feature automated flow regulation to maintain stable temperature levels despite grid fluctuations.
Our plate coolers and thermal systems are designed for specific industrial operations throughout the Czech Republic:
In the heavy industrial automotive corridors of Bohemia and Moravia, our plate coolers help regulate temperature in electrophoretic painting booths, robotic welding cooling loops, and high-pressure hydraulic power systems. Maintaining precise temperature limits is essential for paint adhesion and process consistency.
Our detachable plate heat exchangers are built to handle high pressure differences between municipal primary loops (often exceeding 1.6 MPa) and building heating systems. They facilitate efficient thermal transfer while isolating fluid circuits to protect downstream infrastructure.
Operating in chemical processing zones like Litvínov and Kralupy nad Vltavou, our heat exchangers manage heat recovery from corrosive process flows. By utilizing titanium and specialty alloy plates, they withstand aggressive media, reduce maintenance needs, and lower operating costs.
To support compliance with the EU Water Framework Directive, Czech factories use our membrane concentration and multi-effect evaporation systems. These units process industrial effluents, reclaim clean water for reuse, and extract valuable salts, helping facilities work toward Zero Liquid Discharge (ZLD).
In Pilsen, České Budějovice, and other major brewing centers, thermal efficiency is critical to pasteurization, wort cooling, and fermentation temperature control. Our gasketed plate coolers use FDA-compliant elastomers and sanitary connections to meet strict food safety standards.
Every plate heat exchanger and modular sub-station undergoes a rigorous manufacturing and testing sequence to ensure field reliability:
Plates are pressed using high-tonnage hydraulic presses, forming precise chevron channels that ensure consistent fluid dynamics across the entire plate surface.
Advanced laser systems trim plate edges and port holes, producing burr-free surfaces to secure tight gasket seals and minimize bypass leakage risks.
Stamped plates undergo ultrasonic cleaning to remove pressing lubricants. Non-destructive dye penetrant testing is then performed to detect micro-fractures.
EPDM, NBR, or Viton gaskets are precisely positioned using mechanical clip-on or specialized adhesive methods, followed by thermal curing for maximum seal stability.
Plates are assembled within heavy-gauge carbon steel frames and compressed with high-tensile tie bolts, complying with safety regulations for pressure equipment.
Every assembled heat exchanger is pressure tested at 1.3 to 1.5 times its design pressure limit. Dual-circuit testing ensures no cross-contamination or external leaks.
As the Czech energy market integrates more decentralized renewable sources—such as solar thermal, geothermal, and heat recovery from data centers—thermal systems must adapt to variable operating conditions. Flotte is developing solutions designed for these modern networks:
Our products are engineered for international compatibility, offering design options that conform to ASME Section VIII, PED 2014/68/EU, and EN 13445 standards. We supply full material traceability documents (EN 10204 3.1) and pressure test certifications with every order destined for European installation.

Common engineering questions regarding plate cooler selection, installation, and compliance for installations in the Czech Republic and wider EU.
For municipal district heating sub-stations in Central Europe, the standard configuration is AISI 316L stainless steel plates, which offer good corrosion resistance in domestic water systems. If the primary thermal source uses high-temperature steam or geothermal fluid, EPDM-HT (high-temperature ethylene propylene diene monomer) gaskets are used to withstand operating temperatures up to 160°C. For industrial process water with high mineral content, we design plates with specific wave geometries to promote turbulence, helping to reduce mineral scaling and maintain system efficiency.
Yes. All thermal equipment exported to the EU and Czech Republic conforms to the Pressure Equipment Directive (PED) 2014/68/EU and EN 13445 codes. We supply CE markings, hydrostatic pressure test reports, weld inspections, and EN 10204 3.1 material traceability certificates. This ensures your project complies with Czech safety regulations and standard inspection codes.
For standard plate heat exchangers, manufacturing is completed within 3 to 4 weeks. Shipping is arranged via direct rail freight (the New Silk Road route to terminals in Prague or Česká Třebová), taking approximately 15 to 20 days. Urgent shipments of replacement plates or gaskets can be sent via air express within 5 to 7 days, minimizing downtime for your processes.
Unbalanced hydraulic loops can lead to uneven flow rates, causing some thermal stations to overheat while others experience reduced pressure. By combining our detachable plate heat exchangers with intelligent balancing valves and temperature collectors, flow rates are dynamically regulated based on real-time demands. This maintains the designed thermal drop (LMTD) and keeps return temperatures low, optimizing secondary network efficiency.
Yes, we offer custom-engineered replacement plates and gaskets compatible with major international heat exchanger brands. By analyzing your existing system's dimensions, plate configurations, and nozzle orientations, we can supply replacement bundles that drop directly into your current setup. This restores design performance without requiring costly modifications to your piping infrastructure.
