Explore our premium selection of certified heat exchangers engineered for superior low-temperature performance, compact footprints, and high thermodynamic efficiency.
Standard heat exchangers suffer from severe metal embrittlement and gasket degradation when exposed to cryogenic environments. Our specialized low-temperature models utilize premium grade austenitic stainless steels, titanium plates, and custom-cured elastomeric gaskets designed to withstand extreme thermal contractions down to -196°C without leakage or deformation.
By implementing patented corrugated plate geometry, we force working fluids into high-frequency turbulent patterns at low Reynolds numbers. This micro-forging and plate design increases heat transfer coefficients by 2 to 3 times compared to conventional shell-and-tube models, ensuring maximum efficiency with minimal fluid volume.
Low temperature thermal extraction allows municipal networks and heavy industrial complexes to salvage waste heat that would otherwise be vented. By integrating our modular units into district energy and secondary networks, operators significantly reduce fossil fuel reliance and comply with stringent European and American environmental mandates.
Established in 2013 with a robust registered capital of 101 million yuan, Flotte Energy Saving Company traces its prestigious lineage back to Flotte Thermal Engineering founded in 1995. With nearly thirty years of uninterrupted technical expertise, Flotte has evolved into a global titan in the water equipment, industrial HVAC, and water treatment industries.
Our core operational values center on high-performance manufacturing, rigorous quality validation, and collaborative global trade logistics. By utilizing cutting-edge manufacturing processes, Flotte systematically produces integrated systems that exceed standard industry benchmarks, serving as a trusted OEM/ODM partner for enterprises across the Americas, Europe, Central Asia, and beyond.
Our design department consists of certified senior thermal engineers with decades of cumulative industry experience. Supported by our dedicated state-of-the-art R&D center and advanced thermodynamic testing laboratory, we simulate extreme operational environments to guarantee safety, pressure resistance, and thermal efficiency.
Procuring heavy thermal machinery demands compliance with global safety codes, materials traceability, and extreme mechanical durability. We offer tailored industrial packages addressing the specific regulatory environments of regional markets.
Compliance with the Pressure Equipment Directive (PED) and EN standards is mandatory. Our plate heat exchangers are built with optimized channel depths, delivering the high heat transfer efficiency required for low-temperature heating networks and geothermal heat extraction grids.
Corrosive sub-zero chemical processes require extreme materials integrity. We supply exchangers equipped with Titanium (Gr.1/Gr.11) and Hastelloy plates, paired with high-performance gasket systems that prevent dangerous inter-fluid cross-contamination during thermal cycling.
Modern high-rise commercial structures require highly efficient, space-saving heat exchange units. Our compact, integrated, and intelligent box-type heat exchanger units fit easily into narrow basement machinery rooms, cutting down system installation time by up to 60%.
Flotte's manufacturing facility combines advanced heavy industrial machinery with rigorous ISO-certified management systems to build high-performance thermal units. Discover our end-to-end production process.
Adhering strictly to the concept of "Quality First, Winning by Quality", our production facility features a comprehensive Quality Assurance (QA) system. From metallurgical testing of incoming titanium and stainless steel plates to final pressure containment tests, every step is fully documented. Our operations comply with the international ISO 9001:2015 quality management system, ISO 14001 environmental framework, and ISO 45001 occupational safety guidelines. This systematic approach ensures our heat exchangers deliver durable, leak-free performance in demanding low-temperature applications.
Our products are manufactured to meet stringent international standards and safety protocols. All certification documents undergo periodic reviews and audits by authorized third-party testing institutions.

For sub-zero applications, austenitic stainless steels (such as SS304 and SS316L) are standard due to their ductility at low temperatures. In highly corrosive environments or marine environments, high-grade titanium (Gr.1/Gr.11) is used. Gaskets are selected based on temperature limits, with specialized NBR and EPDM formulations covering temperatures down to -40°C, and custom metal-to-metal or PTFE seals utilized for cryogenic cycles.
Our corrugated plate design features computer-modeled herringbone patterns that disrupt laminar flow and induce high-frequency fluid turbulence. This significantly increases the heat transfer coefficient, delivering 2 to 3 times the thermal efficiency of traditional shell-and-tube heat exchangers with a much smaller physical footprint.
Modular box-type systems are self-contained and pre-engineered for simple integration. They include the plate heat exchanger, intelligent piping, control systems, and monitoring sensors in a compact, protected enclosure. This design minimizes on-site installation time and labor cost, offering a plug-and-play solution for HVAC networks.
All Flotte units undergo rigorous hydro-testing and pressure containment checks. We are certified by the National Boiler and Pressure Vessel Standardization Committee. Our manufacturing utilizes advanced micro-forging and hydraulic assembly techniques to ensure structural integrity and leak-free performance under pressure.
Yes. By combining our plate heat exchangers with room temperature collectors and intelligent unit balance valves, operators can build real-time monitoring networks. This setup allows for automated flow and temperature adjustments based on demand, reducing waste heat and improving overall system efficiency.
Our patented plate geometries are designed to maintain high shear stress at the plate surface, creating a self-cleaning action that reduces scale buildup. For applications prone to high mineral content, we offer detachable plate designs for straightforward cleaning and maintenance, along with optional automated scale-removal systems.
Our systems are engineered to handle a wide range of fluids, including water, glycol solutions, refrigerants, hydrocarbons, industrial chemicals, and wastewater. Materials and gasket configurations are selected to ensure compatibility with your specific working fluids.
Flotte is certified under ISO 9001:2015 (Quality), ISO 14001 (Environmental), and ISO 45001 (Occupational Health & Safety) systems. Our products also hold safety registrations and mandatory national product certifications, allowing us to supply projects in Europe, North America, Central Asia, and other global regions.
