Flotte Energy Saving Company was officially established in 2013 with a registered capital of 101 million yuan. Its origin dates back to Flotte Thermal Engineering founded in 1995. With over three decades of accumulated industrial experience, the company has grown into a leading domestic and global force in water equipment, HVAC systems, and water treatment technologies.
By leveraging cutting-edge manufacturing setups, high-precision thermal dynamics research, and proprietary technologies like our specialized Scale Removal Systems, Flotte stands at the forefront of the thermal efficiency transformation. We maintain a large market share and serve major industrial domains including thermal power, chemical processing, and pharmaceutical engineering.
Our modern production base seamlessly integrates advanced CNC machining, stamping presses, and rigorous testing lines under the ISO 9001:2015 Quality Management System framework. We produce up to 4,500 advanced heat exchange units and smart municipal water units annually. Generating over 500 million yuan in annual sales, and contributing 15 million yuan in local taxes and profits, Flotte represents economic stability and reliable supply chain support for global buyers.
Industrial manufacturing is shifting towards higher thermodynamic efficiency, compact footprints, and reduced maintenance costs. In this landscape, Spiral Wound Heat Exchangers (SWHE) have emerged as a vital technology for critical applications. When procurement teams from LNG plants, oil refineries, and large-scale district heating projects evaluate suppliers, they focus on several primary parameters:
SWHE designs utilize concentric layers of helically coiled tubes. This creates a highly turbulent counter-current flow, resulting in heat transfer coefficients that are up to 2-3 times higher than conventional straight shell-and-tube designs. This means you need less surface area for the same thermal duty.
The spiral spring-like design allows the tubes to expand and contract freely under extreme temperature shifts (thermal cycling). This eliminates the stress concentration points typical in fixed tubesheets, significantly reducing the risk of mechanical failure and tube-to-tubesheet joint leaks.
Continuous spiral channels ensure there are no stagnant fluid zones. The continuous curving path creates secondary flow patterns that help scrub tube walls, delaying scale buildup and fouling. This keeps the unit running longer between maintenance cycles.
Flotte integrates advanced thermodynamics with precise metallurgy. Our product line goes beyond simple heat transfer units to include smart regulation systems, motorized hydraulic balance valves, and high-precision temperature data collectors.
Our custom corrugated geometry induces local micro-eddies in the fluid stream. This design boosts the heat exchange rate by up to 300% compared to smooth tube equivalents while keeping pressure drops within specified limits.
Depending on your fluid chemistry, we manufacture using high-grade stainless steel (304, 316L), duplex alloys, and pure titanium. This selection ensures robust corrosion resistance and longevity in harsh marine or chemical environments.
By integrating balance valves and room temperature collectors, our systems adjust flow rates dynamically based on load variations. This helps operators achieve system-wide thermal balance and lower municipal heating costs.
Flotte maintains a quality assurance system that monitors every step of production. Our facility uses advanced metallurgy equipment, CNC machinery, and high-pressure inspection rigs to ensure all equipment complies with safety standards before dispatch.
Flotte offers a comprehensive product range that addresses diverse challenges across the water treatment, HVAC, and industrial process markets. Here is an overview of our main equipment classifications:
Flotte operates under international quality and management standards. We have obtained ISO9001 Quality Management System, ISO14001 Environmental Management System, and ISO45001 Occupational Health and Safety Management System certifications. Our products have also received safety registration for plate heat exchangers from the National Boiler and Pressure Vessel Standardization Technical Committee.
Spiral Wound units offer higher heat transfer coefficients (2 to 3 times higher) because their helical tube bundle generates continuous flow turbulence. They also have a smaller footprint and are less susceptible to thermal stress failures during rapid temperature changes.
Our scale removal system uses targeted flow turbulence and localized pressure management to break down and flush scale deposits before they can harden. This helps maintain stable heat transfer efficiency and extends the time between manual cleanings.
Yes. The helical design allows the tube bundle to expand and contract under thermal stress, which prevents cracks at the tube-to-tubesheet joint. We fabricate our units using materials like Stainless Steel 316L, duplex steels, and titanium to handle challenging industrial processes.
Heating systems can experience hydraulic imbalances, where buildings closer to the heat source receive more flow than those at the end of the line. Intelligent balance valves adjust hydraulic resistance in real-time, helping to distribute heat evenly and reduce municipal pumping energy costs.
All raw materials undergo incoming inspection, and components are tracked during stamping, assembly, and welding. Completed units are subjected to pressure and leakage testing at 1.25 to 1.5 times their design pressure to verify mechanical integrity before shipment.
