Tempco already has several applications of temperature control units designed to meet the specific thermoregulation needs of molding carbon fiber components. The unit pictured below is a temperature control unit we recently supplied to a company in the province of Bergamo, specializing in the production of custom carbon fiber components for high-performance vehicles as well as other applications.

Tempco’s TCUs have a wide range of applications in the automotive sector, supporting our clients in defining the design and engineering process using a DFM (Design for Manufacturing) approach, aimed at achieving an ideal balance and harmony on both fronts. Maximizing aesthetic appeal while simultaneously enhancing the mechanical and structural performance of the components.

This is another important step towards the realization of Baglietto’s Bzero project, a true ‘promise made to the sea’ from the shipbuilder, aimed at implementing a green hydrogen production module on its yachts for zero-emission navigation. Using filtered and deionized seawater, Bzero will be able to produce hydrogen with a purity of grade 5.0 at a maximum pressure of 35 bar, using a system of AEM electrolyzers (for a total power of approximately 55 kW), powered mainly by energy from renewable sources.

Baglietto’s zero-emission yacht for sustainable navigation uses photovoltaics to power electrolyzers, which produce green hydrogen directly from seawater. These in turn power an onboard PEM fuel cell system, enabling navigation in full-electric or hybrid mode. The propulsion system is automatically selected by the yacht’s advanced navigation systems to ensure the best balance between performance and efficiency. The cooling systems provided by Tempco, one of the partners in this important project, play a key role in the entire process: precise, constant, and reliable temperature regulation of all the yacht’s power electronics.

Going more in depth, as detailed by Baglietto itself, the hydrogen produced is stored in solid state, at low pressure and ambient temperature, inside metal hydrides tanks (MH storage). The hydrogen storage and release process is managed by a thermal management system that heats the metal hydrides during discharge and cools them during recharging. The required thermal energy is recovered from the heat generated by a PEM fuel cell module, with a capacity of approximately 185 kW, which uses hydrogen as fuel to produce zero-emission and zero-noise electricity. The generated power is regulated via a DC/DC converter on a 700 V DC central bus, a solution already tested on Baglietto yachts equipped with hybrid technology. Connected in parallel to the fuel cell on the same bus is a set of lithium-ion batteries designed to absorb peaks and sudden variations in user energy demand.

The operations conducted on the prototype created in port are aimed at optimizing the technical aspects to obtain the necessary RINA certifications for hydrogen tank refueling operations and speeding up the procedure, while also ensuring the highest levels of process safety.

These activities are crucial for the future of sustainable mobility, essential for the development of more sustainable technologies for the future of the automotive industry. We therefore extend our sincere thanks to Giacomo Silvagni, PhD Assistant Professor at Alma Mater Studiorum – University of Bologna, responsible for these projects at the University Department, who provided us with detailed information on two of the ongoing research projects.

The first image, in the scheme below, shows the construction of a flow bench for experimental diesel and gasoline common rail GDI (Gasoline Direct Injection) injectors, aimed at hydraulic characterization of the injection system and the development of control-oriented models.

As Giacomo Silvagni explains, high-pressure injection systems are typically used in control strategies with multiple, closely spaced injections. These strategies generate dynamic pressure wave effects and electromagnetic interactions that induce deviations from the normal injector operation, causing imbalances in the torque delivered by the engine from cylinder to cylinder, resulting in reduced efficiency and increased pollutant emissions. Thanks to the flow bench, built within the laboratories of the Department of Industrial Engineering of the University of Bologna, it was possible to carry out ad hoc experimental campaigns to experimentally characterize the tested injection systems, both diesel (up to 1,800 bar) and gasoline (up to 700 bar), and to develop control-oriented physical models aimed at real-time compensation of these dynamic phenomena compatible with standard engine control units.

For this first application, the Tempco temperature control unit was a central component of the test system, used to regulate the fuel temperature within the injection systems. The TCU therefore allowed for precise control of the fluid temperature, which is crucial for ensuring the repeatability of the experimental tests, and simultaneously verified the impact of different fuel temperatures on the system’s hydraulic dynamics.

The other two images below relate to the study for converting a 1.3-liter multijet diesel engine to operate on compression-ignition gasoline, aimed at studying high-efficiency combustion modes.

The study of innovative, high-efficiency, low-emission combustion methods is part of the ongoing development of internal combustion engines for high-efficiency, low-emission applications. Innovative combustion methods still represent one of the most promising solutions, especially considering the advent of synthetic and sustainable fuels. To verify the benefits of these technologies, a small 1.3-liter multijet internal combustion engine, originally designed for diesel compression ignition, was converted to GCI (Gasoline Compression Ignition) operation in the laboratories of the Department of Industrial Engineering at the University of Bologna. This activity allowed to verify the benefits of this combustion method, both in terms of efficiency and pollutant emissions, compared to traditional diesel operation. The entire engine operating range was replicated while maintaining all internal engine components in their stock production configuration, thus verifying their full applicability to off-the-shelf hardware already on the market.

The Tempco temperature control unit, as Silvagni further explains, was a central element of the test system as it was used to regulate the temperature of the air drawn into the engine during start-up. Thanks to the Tempco temperature control unit and the use of a dedicated air-oil heat exchanger, it was possible to increase the temperature of the air drawn into the engine before it entered the combustion chamber, thus promoting spontaneous ignition of the gasoline. The precise control achieved by the Tempco system also allowed to verify the impact of different combustion air temperatures on combustion stability and engine performance in terms of torque/power output and pollutant emissions.

Also for pharmaceutical applications, we recently supplied three TREG temperature control units for silicone fluids in glass-lined reactors. This is a classic mono-fluid temperature control application, equipped with heating via electric resistors and a low-temperature cooling section (-30°C) using brazed plate heat exchangers and mixing valves.

Temperature ramps control is achieved through dedicated electronic thermoregulators and thyristors (SCR), which allow the customer to drive the heating elements with modulating power. Finally, the thermal control units work with special pumps, featuring magnetic drive technology and a very wide temperature range of -30/+300° C.

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.

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.

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!
