Engineered to support regional heating projects and municipal utilities in Portugal, ensuring low maintenance overheads and maximum thermal transfer coefficient (U-value).
Portugal is paving a rapid, definitive path towards its National Energy and Climate Plan (NECP 2030) targets, committing to source over 85% of its electricity production from renewables and aggressively reducing primary energy consumption in industrial facilities. As direct fossil fuel combustion is phased out, major sectors such as Pulp and Paper (concentrated in Aveiro, Setúbal, and Figueira da Foz), Chemical Refining (centered in Sines), and Food Processing & HVAC networks are undergoing heavy system optimizations.
Within this macroeconomic shift, thermal recovery and energy savings are the highest-return investments. Plate Heat Exchangers (PHEs) provide an ultra-compact footprint compared to legacy shell-and-tube units, running with a much closer temperature approach (frequently down to 1°C). This allows Portuguese industrial facilities to reclaim low-grade waste heat from effluent loops, boiler blowdowns, and condensation systems, re-channeling it directly back into operations.
1. Material Considerations: In coastal processing areas such as Sines or Matosinhos, standard 304 stainless steel is highly vulnerable to stress corrosion cracking due to ambient chloride concentration. Flotte recommends AISI 316L as a baseline, and Titanium Gr. 1 for raw seawater cooling configurations.
2. Municipal Compliance: Municipal heating networks in Lisbon and Porto demand compliance with EU pressure vessel directives. All Flotte equipment supplied to Portugal features CE stamping and complete PED 2014/68/EU verification, ensuring swift domestic certification and safety approvals.
Established in 2013 with a registered capital of 101 million yuan, Flotte Energy Saving Company originated from Flotte Thermal Engineering founded in 1995. With three decades of field-proven technical expertise, we serve water equipment, HVAC, and industrial process industries globally.
Flotte holds multiple national patent certifications including the "High-Efficiency Plate Heat Exchanger", "Intelligent Plate Heat Exchanger System", and "Plate Heat Exchanger Scale Removal Device". Our manufacturing processes have obtained the safety registration for plate heat exchangers issued by the National Boiler and Pressure Vessel Standardization Technical Committee, and are fully certified under ISO9001:2015 (Quality Management), ISO14001:2015 (Environmental Protection), and ISO45001:2018 (Occupational Health and Safety).
Specially optimized for industrial waste heat integration, desalination projects, and district heating plants across Porto, Sines, and Coimbra.
How Flotte uses advanced fluid dynamics (CFD) and material science to meet the demands of highly demanding environments.
Our plates are stamped with a proprietary chevron pattern design (30° and 60° inclination angles). By combining high-theta and low-theta plates within a single frame pack, we optimize both pressure drop limits and heat transfer rates for specific flow rate requirements.
Gasket longevity is the foundation of structural reliability. We offer clip-on (glue-free) NBR and EPDM gaskets manufactured under strictly controlled vulcanization processes, guaranteeing dynamic seals that withstand working temperatures up to 180°C and pressures up to 4.0 MPa.
Our industrial-grade detachable frames feature epoxy-coated carbon steel compression plates and zinc-plated tightening bolts with bearing boxes, permitting rapid disassembly for plate cleaning, CIP (Clean-In-Place) flushing, and expansion.
Step-by-step documentation of our manufacturing processes, ensuring compliance with pressure vessel standards and international quality guidelines.
Heavy duty CNC oxy-fuel and plasma cutter systems ensure accurate plate borders and bolt hole alignment for the frame assembly.
High precision forging operations are utilized to strengthen the connection nozzles and stress points of the plate frames.
Multilayer anti-corrosion industrial coatings protect the external frame structure from marine environments and industrial chemicals.
Raw metal coils are precision cut and lasers trace unique product serial codes for 100% material traceability back to the steel mill.
Each unit undergoes strict hydrostatic pressure tests at 1.3 to 1.5 times the design working pressure to verify seal integrity before dispatch.
Trained, certified specialists assemble the plate packs and gaskets under specific torque requirements to guarantee even compression.
Elastomeric sealing compounds are precision molded and applied to critical ports to prevent corrosive chemical bypass.
High speed automated mechanical stamping presses form the plate ports with zero stress deformation on the metal margins.
Heavy tonnage hydraulic press machines stamp the corrugated chevrons on stainless steel or titanium sheets in a single operation.
Our systems are fully compliant with domestic European industrial standards, backed by robust testing protocols.
Fluctuating raw material prices and logistics disruptions require an exporter with absolute control over its supply chain. Operating out of our modern 70,000 m² manufacturing plant, Flotte maintains direct partnerships with top-tier raw steel suppliers like POSCO and Outokumpu. We hold massive reserves of standard coils (AISI 304, AISI 316L, and Titanium Gr. 1) in stock, insulating our Portuguese clients from sudden price spikes and reducing standard lead times to 4–6 weeks.
Our Factory 4.0 layout integrates automated CNC manufacturing, mechanized hydraulic presses, and intelligent monitoring systems. This scale of operation enables us to control tolerances tightly, perform exhaustive test sequences, and offer competitive pricing. Working alongside global shipping carriers, we manage the entire export flow, including custom shipping wooden crates, port logistics from Qingdao/Shanghai, and door-to-door delivery across Portugal.
