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.

CRN (Canadian Registration Number) number is a unique code issued by Canadian provincial/territorial authorities, required for the installation and use of pressure equipment, such as boilers, heat exchangers, pressure vessels, and fittings (fittings, valves, piping) in Canada. CRN certification is mandatory for equipment operating at pressures above 15 psig (approximately 1 bar) and, in the case of Tempco, ensures that the design and engineering of our brazed heat exchangers comply with Canadian safety standards.

A key safety requirement for importing and installing pressure-bearing components in Canada, this new certification, combined with the ASME certification, ensures that Tempco brazed plate heat exchangers comply with Canadian industry standards. Specifically, the CRN code is valid for installation of our brazed plate exchangers in the provinces of Ontario (ON), Quebec (QC), British Columbia (BC), Alberta (AB), and Saskatchewan (SK).

This new certification for installations in the Canadian market adds to the certifications Tempco has achieved over the years for its thermal control and industrial thermoregulation solutions such as ATEX for operation in potentially explosive atmospheres, such as in the chemical, petrochemical, and pharmaceutical sectors, and the ones for our TREG thermoregulation TCU units, which are UL certified for the North American market and EAC certified for Russia and the EAEU (Eurasian Economic Union) countries.

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.

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.

With such a prestigious reference, Tempco is very proud to have contributed to ensuring the high performance of Dallara cars, thanks to the supply of a TREG HE temperature control unit employed for radiator test benches of Dallara Automobili’s racing cars. The unit is specifically designed to heat a thermal oil circuit, operating in a temperature range of +30°C to +180°C and transferring heat to the test fluid via a brazed plate heat exchanger. The flow rate range of the test fluid is between 5 and 80 l/min.

Test benches for these components are essential for laboratory simulation of the same track conditions that the cars will be subjected to during races. Tempco’s thermal control unit is therefore meticulously designed to ensure the simulation of the thermal conditions in which the Dallara supercar radiators will operate, precisely regulating the flow rates and temperatures of the test fluid with great stability and repeatability (temperature regulation accuracy ± 2°C).

Behind every tested radiator, there is thus a control unit that ensures that every degree truly counts in determining the maximum performance of Dallara racing cars. At the heart of the test bench, the TREG HE thermal control unit uses low-specific-power resistors, offering PID-controlled temperature regulation with proportional SCRs and integrated safety logic. An electro-pneumatic modulating valve ensures the necessary heat transfer stability even at low flow rates (5 l/min), maintaining the correct turbulent flow rate on the brazed exchanger.

Finally, the system was designed to always maintain maximum efficiency in regulating the temperature of the test fluid, taking into account the strong variability of the fluid’s viscosity as the temperature varies, together with the need to contain pressure drops.

This specific application for the medical sector requires a precise and controlled cooling of the air temperature within the medical tubing thermoforming line. Rapid and stable cooling allows indeed the final geometry of the tube to be set immediately after forming, ensuring repeatability and consistent quality.

The solution used is an air/water exchanger made of UNI6082 aluminum with a special ElectroFin treatment. It is ideal for medical environments thanks to the corrosion resistance and sanitization of the surfaces guaranteed by the special treatment. This involves a series of steps that include testing and inspection of incoming parts, cleaning and degreasing of production residues, and e-coating in a cathodic epoxy bath. All with complete process traceability.

Integrated into the machine, the heat exchanger works with precisely regulated chilled water, maintaining the air temperature within the range required by the process. Thanks to the precise control of the air temperature in the thermoforming line, the result offered by the solution therefore involves greater stability, reduced waste and repeatable quality of the medical product.

For this reason, we have been promoting the Tempco Service for years, a periodic maintenance program tailored specifically for our TREG thermoregulation units, cooling systems, thermoregulation skids, and custom control units.

The Tempco service specifically includes:

• complete check of operating parameters;
•  exchanger performance verification;
• pump, valve, seal, and sensor inspection;
• heat transfer fluid analysis and recommendation for replacement;
• software updates and regulator calibration;
• advance notification of components requiring replacement.

The customer benefit is therefore very simple: zero surprises and maximum operations continuity. Scheduled maintenance allows also to:

• avoid unexpected downtime;
• keep energy consumption under control;
• extend the life of your machines;
• plan budgets and production downtime;
• have priority access to our technical support.

Service also provides an opportunity to propose upgrades or new energy efficiency solutions, such as optimizing thermal cycles or introducing more efficient heat recovery systems.

At Tempco, we therefore don’t see maintenance as a ‘cost’, but rather as an investment to ensure that thermal machines perform exactly as they did on day one, along with the opportunity to continuously improve and optimize the operational efficiency of your thermal management and temperature control systems.

With original Tempco spare parts, however, the customer knows exactly what they’re installing, with the peace of mind of ensuring:

• materials compatible with the process fluid;
• guaranteed performance tested on our systems;
• compliance with pressure and temperature specifications;
• long-term reliability thanks to the selection of suppliers we’ve worked with for years.

The difference, therefore, lies not only in the quality of the components themselves, but also directly impacts operational continuity: a correct gasket maintains the efficiency of the exchanger; a certified pump guarantees effective flow; consistent resistance prevents overheating or excessively frequent start-up cycles.

Furthermore, in a heating system, every deviation generates inefficiencies and hidden costs: higher energy consumption, longer rise/fall times in temperature, and micro-stoppages in production.

For all these reasons, at Tempco we always remind our customers that an original spare part costs less than a system downtime.

Tempco offers a dedicated service for the rapid supply of spare parts, even for older or custom-built machines. Keeping your systems in ideal condition thus means preserving their useful life, ensuring consistent performance.
