Discover our highly efficient heat exchangers designed for district heating, HVAC, and industrial processes.
The trajectory of China's heat exchanger development mirrors the industrial modernization of the nation. Founded in 1995 as Flotte Thermal Engineering, our enterprise underwent a strategic restructuring in 2013, establishing Flotte Energy Saving Company with a registered capital of 101 million yuan.
Through three decades of dedicated research and development, we have transitioned from fabricating traditional, low-efficiency shell-and-tube setups to engineering highly sophisticated plate heat exchangers (PHE) and intelligent secondary network integrated units. Our systems are engineered to address critical energy demands in water equipment, HVAC networks, and advanced municipal water treatment systems.
Understanding the raw material control, manufacturing speeds, and structural engineering advantages of a leading Chinese OEM/ODM exporter.
Our patented plate designs feature optimization of corrugation angles and depths. This yields a heat transfer coefficient (U-value) that is 2 to 3 times greater than traditional shell-and-tube setups, significantly lowering footprint requirements.
Operating strictly under ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 systems, our products hold national pressure vessel safety registrations and comply with leading global construction codes.
From customized skid design to rapid supply chain sourcing of rare alloys (such as Hastelloy, Titanium, and Nickel plates), our manufacturing pipeline delivers reliable operation across highly corrosive environments.
Every stage of manufacturing—from raw plate pressing to high-pressure validation—is conducted within our 70,000㎡ facility.
CNC cutting of heavy frame plates, ensuring precise dimensional tolerances for reliable gasket compression.
High-precision surface enhancement to relieve metal stress and improve fatigue life under cyclic pressure.
Application of multi-layer anti-corrosion coatings to withstand harsh industrial and outdoor environments.
Laser sheet cutting integrated with laser etching barcodes for full material traceability (heat numbers).
Rigorous hydrostatic testing at 1.3 to 1.5 times the design pressure to guarantee leak-free operation.
Precision torque tightening of frame bolts to maintain parallel alignment of the plate bundle.
Precision bonding or clip-on installation of premium elastomer gaskets (EPDM, NBR, FKM).
Punching of connection ports with smooth edge finishing to prevent localized stress cracks.
One-step hydraulic forming using heavy-tonnage presses to achieve highly precise corrugation profiles.
How Flotte systems are utilized across complex modern heating, manufacturing, and industrial projects.
In centralized district heating networks, municipal supply lines operate under high pressures. Flotte plate heat exchangers function as high-efficiency isolators, ensuring safe heat transfer to end-user loops at reduced pressures. This optimizes heating delivery while protecting secondary piping networks from catastrophic pressure spikes.
For wastewater purification in the chemical and pharmaceutical industries, Flotte's Multi-Effect Evaporation Systems and Membrane Concentration Systems are critical. They enable plants to recover up to 98% of clean distillate water, concentrating waste streams and enabling environmental regulatory compliance.
Our Intelligent Integrated Box-Type Heat Exchanger Units provide high-efficiency temperature and pressure zoning for skyscrapers and commercial complexes, reducing structural HVAC energy requirements.
How our technical research is shaping the future of decarbonized thermal networks and industrial evaporation systems.
Focusing on high-turbulent plate shapes to minimize fouling coefficients. Introducing specialized vulcanized EPDM gaskets for high-temperature duties up to 180°C.
Combining heat exchangers, variable frequency pumps, control valves, and sensors into a single integrated frame. Implementing remote PLC-based cloud monitoring.
Utilizing smart Room Temperature Collectors and self-optimizing control valves to eliminate hydraulic imbalance across wide district heating grids.
Pairing advanced membrane concentration with multi-effect evaporation to assist industrial plants in eliminating thermal pollution and wastewater discharge.
Customized configurations engineered by Flotte Thermal Laboratories for complex global industrial demands.
All units undergo rigorous inspection by authorized national bodies to ensure full compliance with international standards.
Tour our workshops equipped with high-tonnage forming presses and fully automated welding networks.
Expert technical answers regarding structural plate selection, system efficiency, and maintenance.
Advanced thermal management equipment, evaporation systems, and smart HVAC controls.
Flotte maintains advanced laboratories and a special R&D center to ensure our heat transfer geometries remain at the leading edge. With a total annual revenue of 500 million yuan and 15 million yuan in taxes and profits, we are a major contributor to local industrial development and a reliable partner for global engineering sourcing. Our products are widely utilized in thermal power, pharmaceutical, and chemical projects. We build solid cooperative relationships with international procurement agents to ensure reliable operations in any environment.
In addition to high-efficiency plate heat exchangers, Flotte designs multi-effect evaporation and membrane concentration systems. These units utilize thermal vapor recompression to concentrate aqueous solutions, supporting wastewater treatment and resource recovery in the chemical processing sector. Our production workshops follow ISO 9001:2015 standards to deliver consistent quality control for critical pressure equipment.
