Established in 2013 with a registered capital of 101 million yuan, and originating from Flotte Thermal Engineering founded in 1995, Flotte represents three decades of industry-leading technical expertise. We specialize in fluid distribution control, high-efficiency district HVAC systems, water treatment processes, and macro industrial energy-saving installations. Over the years, we have positioned ourselves as an essential hub of technology, pioneering new patents and setting gold standards for heat exchange mechanisms globally.
Operating from our 70,000 m² state-of-the-art facility, our manufacturing framework is built on absolute quality control and compliance. We produce over 4,500 integrated heat exchange units and high-pressure water supply systems annually. Our 300+ strong workforce, led by a dedicated, senior thermodynamic R&D engineering unit, ensures we stay ahead of market demands, serving key thermal power, chemical engineering, and pharmaceutical complexes globally.
Our commitment to quality is validated by international regulatory compliance, system certifications, and strict adherence to pressure vessel manufacturing guidelines.
Flotte has continually invested in technology development, securing multiple core patents including the "High-Efficiency Plate Heat Exchanger", "Intelligent Plate Heat Exchanger System", and "Plate Heat Exchanger Scale Removal Device". Our manufacturing pipeline holds the safety registration for plate heat exchangers issued by the National Boiler and Pressure Vessel Standardization Technical Committee. Furthermore, all operations strictly comply with the ISO 9001:2015 International Quality Management System, ISO 14001 Environmental Management System, and ISO 45001 Occupational Health and Safety Management System.
Understanding the dynamic requirements of HVAC engineers, EPC contracting companies, and large industrial facilities worldwide.
As modern industrial operations align with global net-zero regulations, optimizing thermal management systems has become a priority. Plate heat exchangers (PHEs) play a key role in energy recovery, secondary district networks, and industrial waste heat capture. Engineering Procurement Construction (EPC) firms require systems that offer maximum heat transfer area in a compact footprint.
To meet these demands, Flotte manufactures detachable plate heat exchangers and integrated heat exchange units that deliver 2 to 3 times the thermodynamic efficiency of conventional shell-and-tube systems. This helps global industries minimize installation space, reduce energy consumption, and lower operational overheads.
In chemical processing, pharmaceutical synthesis, and district heating plants, heat transfer equipment must withstand corrosive media, extreme pressures, and cyclic temperature fluctuations. The selection of materials is critical to preventing premature failure.
We utilize premium plate alloys (AISI 304, AISI 316L, Titanium, Hastelloy) and gasket systems (NBR, EPDM, Viton) engineered for specific process media. Every unit undergoes rigorous hydraulic validation and pressure testing prior to shipment, ensuring reliable operation in demanding conditions.
Custom-engineered thermal systems designed for municipal, industrial, and processing applications worldwide.
We supply modular, intelligent heat exchange units for municipal primary and secondary networks. Our designs feature patented, high-turbulence corrugated plate patterns that facilitate efficient primary-to-secondary energy transfer while managing pressure drops, ensuring comfortable heating in urban environments.
Handling corrosive fluids and maintaining precise process conditions requires high-performance equipment. Our plate heat exchangers use corrosion-resistant alloys and specialized gasket designs to prevent cross-contamination and ensure long-term thermal reliability under harsh industrial operations.
For high-rise office towers, modern residential complexes, and airport terminals, we supply compact HVAC solutions. Our building heat exchanger units work alongside secondary network balancing valves to manage heat load changes, reducing utility costs and carbon emissions.
Sanitary processes require smooth contact surfaces to prevent microbiological growth. Our sanitary-grade plate heat exchangers feature electropolished plates and gasket systems designed for clean-in-place (CIP) operations, meeting food and pharmaceutical processing safety standards.

Driving innovations in smart heating networks, advanced metallurgy, and zero-fouling plate designs.
The integration of digital technology is changing municipal heating management. Flotte is developing intelligent heat exchange stations equipped with network sensors, secondary network intelligent balancing valves, and high-precision temperature collectors.
These systems feed real-time thermodynamic telemetry into cloud platforms, enabling operators to analyze temperature drops, regulate flow rates, and detect structural anomalies remotely. This predictive approach optimizes heating distribution and helps prevent pipeline scaling.
To improve plate durability and efficiency, our materials research focuses on advanced surface treatments and new alloy combinations. We are testing hydrophobic coatings designed to reduce mineral scaling on corrugated plates, maintaining heat transfer efficiency over longer operating periods.
Additionally, we are exploring thin-gauge titanium and specialized nickel alloys to decrease unit weight while maintaining structural strength in high-pressure steam applications. This supports the transition toward high-temperature energy systems.
A reliable logistics and localized support network engineered to meet global industrial standards.
We coordinate an export pipeline to ensure timely delivery of heat exchange systems to major global logistics hubs. Flotte maintains inventory levels of standard plate configurations, NBR/EPDM gaskets, and balancing valves, helping minimize downtime during emergency maintenance.
Our supply chain and support teams assist clients through all stages of delivery, import customs clearance, and terminal transport. This comprehensive support helps streamline the installation process for international projects.
A successful installation relies on accurate thermodynamic design and setup. Our engineers provide remote and on-site support to assist with unit integration, pressure testing, and parameter balancing.
Every custom unit includes comprehensive documentation, including detailed structural drawings, thermal calculation datasets, hydraulic flow diagrams, and operation manuals. This detailed information helps local installation teams complete commissioning efficiently.
Key technical insights on plate heat exchanger selection, maintenance, and system customization.
Material selection depends on the chloride content, operating temperature, and pH of the media. For standard fresh water or HVAC applications, AISI 304 or AISI 316L stainless steel is typically specified. For seawater, brackish water, or high-chloride chemicals, titanium or specialized nickel alloys are utilized to prevent pitting and stress corrosion cracking.
Detachable (gasketed) plate heat exchangers can be disassembled for mechanical cleaning, inspection, and capacity expansion by adding plates. Brazed plate heat exchangers are compact and handle higher operating pressures and temperatures but cannot be opened mechanically, relying on chemical cleaning (CIP).
Corrugation patterns (such as chevron angles) generate high fluid turbulence even at low velocities. This turbulence disrupts the thermal boundary layer, increasing the heat transfer coefficient by 2 to 3 times compared to smooth-tube systems, while helping to minimize scale buildup on the plate surfaces.
To provide an accurate thermal design, we require: inlet and outlet temperatures for both the hot and cold sides, fluid mass flow rates or heat load requirements, physical properties of the media (density, viscosity, specific heat), and the maximum allowable pressure drop for each circuit.
Our manufacturing processes conform to national safety registrations and ISO standards. We provide material test reports (MTRs), hydrostatic test certifications, welding qualification records, and pressure vessel safety documentation required for international compliance.
Intelligent balance valves dynamically adjust water flow based on feedback from room temperature collectors. This automated control balances hydraulic distribution across the network, reducing energy consumption and preventing uneven heating in different zones.
