Tempco’s PCHE exchangers represent an innovative technology that offers high performance to meet the critical requirements of hydrogen applications, such as extreme pressures and variable temperatures. The construction by diffusion bonding, or solid-state welding, of the plate pack allows these exchangers to operate at pressures up to 900 bar and beyond, thanks to their high structural integrity, which ensures operational reliability and high safety.

The photo-etching technique empployed for the plates allows to create customized layouts of heat transfer microcircuits, allowing PCHEs to be built in multistream mode, as required by the multistage compressors used in hydrogen refueling stations. This ensures extremely high heat transfer efficiency, rapid refueling, and installation in small spaces thanks to the exchanger’s highly compact design.

mcT Hydrogen is held concurrently with several other events, including mcT Oil & Gas and Security, a sector in which Tempco PCHE exchangers find equally important and interesting applications, such as pre-heaters in high-performance turbines and on GLN extraction platforms for gas cooling.

Brazed plate heat exchangers are the ideal solution for these plants thanks to their compactness, high thermal efficiency, and total maintenance-free operation. Compared to traditional shell-and-tube heat exchangers, they offer a series of concrete advantages that make them particularly suitable for modular, high-power density installations in small spaces.

The choice of Tempco
In Tempco hydraulic power plants, brazed plate heat exchangers are custom-sized based on the customer’s operating conditions:

• flow rates
• viscosity
• operating temperature
• heat dissipation duty

The use of copper or nickel-brazed stainless steel heat exchangers ensures high corrosion resistance and long operating life, with consistent thermal performance over time. Their compactness and reliability make them the perfect choice for high-performance systems, where every detail counts to ensure operational continuity and energy savings.

In short, brazed plate heat exchangers maximize thermal transfer efficiency and reduce overall dimensions, simplifying maintenance and improving the reliability of hydraulic power plants.

Fuel cells are electrochemical devices that convert the chemical energy of hydrogen into electrical energy with high efficiency, producing water and heat as a byproduct. Green hydrogen (green H2) is therefore hydrogen generated from renewable energy sources, with no carbon emissions. Water electrolysis is the most commonly used method for hydrogen generation, using a chemical reaction that separates hydrogen from oxygen.

As a green energy, green hydrogen can therefore be used in a variety of sectors, replacing fossil fuels and promoting the energy transition. Green hydrogen can be used for fuel cells, but it can also serve as a direct energy source for aviation, marine, automotive, and heavy-duty transportation, as well as for on-site industrial power generation.

Regardless of the type of electrolytic cell technology – be it PEMEC (proton exchange membrane electrolyzer), AEMEC (anion exchange membrane electrolyzer), AEL (alkaline electrolyzer), SOEC (solid oxide electrolyzer), or any other electrolysis technology – brazed exchangers offer high-value, high-efficiency solutions for electrolysis equipment, electrolytes, reaction water and gas preheating, working fluid cooling, and system energy recovery.

For these hydrogen applications, Kaori offers two types of brazed plate exchangers: the high-nickel alloy exchangers are the ideal solution for high-temperature SOEC/SOFC applications, capable of operating at temperatures up to 900°C. The new full-stainless steel brazed exchangers use stainless steel as the brazing filler material. This makes them suitable for hydrogen generation via PEM electrolysis and for fuel systems, or for low-conductivity deionized water that does not allow the passage of copper ions.

These devices are widely used in temperature control, cooling, and thermoregulation systems in the process industry developed by Tempco. The regulation defines a fan as a device consisting of at least three components: stator, rotor, and motor. The fan must therefore achieve the minimum required energy efficiency at its optimum operating point, where efficiency is calculated as the ratio of airflow performance to electrical power input.

The new Regulation on electric fans also requires more information on partial loads and specifies the documentation requirements for the manufacturer/distributor/user, including information on reparability in addition to efficiency. The regulation thus aims to promote the development of the circular economy through the availability of spare parts.

The new requirements, which increase energy efficiency performance levels for fans compared to those established by the previous Ecodesign Regulation, will therefore further reduce energy consumption in industrial systems for temperature control and cooling. These savings can also be further increased in electric fans through the use of inverters and systems that adapt air volume to actual process needs, thanks to speed regulation.

Fans that comply with the minimum energy efficiency limits set by the regulation are recognized by their CE labeling, certifying their compliance. Only fans that comply with the CE regulation will therefore be allowed to enter the European market, regardless of whether they are manufactured in the EU or imported from non-EU countries.

Finally, a transition period until July 24, 2027 is foreseen to comply with the new efficiency requirements and the extended documentation requirements imposed by the regulation for fans installed in other products, so-called built-in fans.

Now we come to the final stage: forming and cooling, where the chocolate is poured into molds and finally takes its shape.

After tempering, the chocolate mass is rapidly cooled to crystallize uniformly and achieve the ideal consistency. Low, stable temperatures, around 10-15°C, are essential to ensure the chocolate solidifies without defects, such as air bubbles or irregular surfaces. TCU thermal control units also ensure that the process runs smoothly during this phase, avoiding thermal shocks that could compromise product quality. Furthermore, well-managed cooling speeds up production times and optimizes the efficiency of the production line.

The magic of chocolate ends with this phase, leaving us with perfect bars, ready to be packaged and enjoyed. A precision work that transforms each piece into a masterpiece!

One of the most common applications for high-pressure exchangers is gas cooling in compressors, as shown in the photo below: a high-pressure compression system for technical gases, where the exchangers are used to dissipate the heat generated during compression. In these systems, robustness and mechanical sealing are essential to ensure safety, continuity of service, and longevity.

Therefore, these are some of the main advantages offered by this special type of high-pressure brazed exchangers:

• Compact design and simplified installation

• High mechanical resistance, up to 140 bar

• No routine maintenance thanks to the absence of gaskets• High heat exchange efficiency even at low flow rates

• Customized versions available for specific gases, oils, or process fluids

The high-pressure versions of brazed exchangers are also used in heat recovery systems, CO₂ hydraulic circuits, HVAC systems for transcritical refrigerants, and in the hydrogen sector, where operating conditions require absolutely reliable equipment.

The AI/HPC data centers sector is therefore accelerating its transition toward the use of large-scale liquid cooling technologies, driven by the achievement of sustainability targets and high power efficiency (PUE) values ​​in new, large, high-performance data centers. To address this significant trend, Kaori, a Tempco partner in the field of heat transfer, recently introduced two new heat exchangers with highly attractive features specifically designed for new liquid cooling solutions in high-performance infrastructures.

This is the B390 heat exchanger, which features an asymmetric plate design specifically designed for high-density AI and HPC data centers. With a cooling capacity of up to 2.000 kW and support for 4-inch high-flow connections, it easily manages the transient heat loads of next-generation high-power servers. Measuring only 321 mm in width and 751 mm in length, the B390 offers exceptional cooling performance in a compact footprint—perfectly integrating into In-Row CDU systems while maximizing space efficiency.

Optimized for the pressure drop differences on both sides of In-Row CDU systems, the B390 ensures stable flow distribution and higher overall performance. It is available in single or multi-pass configurations and supports vertical, horizontal, or flat installations, providing flexible integration for various system and space requirements in data center environments.

B390 continues the core advantages of Kaori’s B Series:

• Exclusive plate pattern design: maximizes heat transfer efficiency while maintaining low pressure drop.
• High working pressure construction: ensures long-term reliability for high-pressure liquid cooling systems.
• Compact design: pptimizes space utilization to meet high-density integration needs.

A second interesting heat exchanger model, also developed specifically for next-generation, high-density data center environments in the AI ​​era, is the K390. The same-sized K390 heat exchanger features a symmetrical plate design, ideal for balanced bidirectional flow systems.

Together, the B390 and K390 form a complementary solution, offering greater design flexibility and performance options for in-row liquid cooling architectures.
