A preventive check before summer is therefore essential to ensure production continuity, consistent performance, and controlled energy consumption.

A system that is not properly checked can encounter a series of interconnected problems during the summer months:

• Reduced cooling capacity, making it impossible to maintain the required process conditions
• Increased energy consumption, as the system operates unpredictably to compensate for inefficiencies
• Alarms and sudden shutdowns, often during peak production periods
• Loss of downstream process efficiency, with consequences for quality and productivity

To safely handle summer loads, a suitable best practice is to plan a systematic system check in advance. The main points to check are the followings:

Cleanliness and condition of heat exchangers. Heat transfer surfaces must be clean and free of deposits or fouling. Even a thin layer of fouling can significantly reduce the overall heat transfer coefficient (U), degrading the unit’s rated performance. The check must include both the process and service sides.

Water circuit and water quality. Pipe scaling, localized corrosion, and deterioration of cooling water quality are among the most common causes of problems during the summer season. It’s important to check the pH, hardness, and concentration of any inhibitors, as well as verify proper circulation within the circuits.

Ventilation and condensation components. In dry coolers and evaporative cooling towers, the condensation section is the first to be affected by high external temperatures. Checking that the fans are working properly, that the fins are clean, and that there are no obstructions to the airflow is essential to avoid compromising the unit’s capacity.

General functional check. The inspection must be completed with a comprehensive functional check: calibration of temperature and pressure controls, condition of control components, alarm management, and verification of the correct operating sequence under peak conditions.

Preventive maintenance conducted before summer allows for the identification and resolution of critical issues while there is still time to do so, avoiding emergency interventions during peak production periods.

Among the cooling solutions offered by Tempco for data centers, particular attention is paid to the most innovative liquid cooling technologies, which offer greater efficiency in dissipating heat generated by chips – and therefore better temperature regulation – thanks to the superior thermal conductivity of liquids compared to traditional air cooling solutions. Tempco brazed plate exchangers therefore serve as a key technology for CDUs – Coolant Distribution Units – used in the liquid cooling of high-performance data centers, a strategic path to reduce the environmental impact of data centers, increase their sustainability and improve energy consumption efficiency (PUE, power usage effectiveness).

The improved thermal management made possible by liquid cooling also allows data centers to operate at higher power densities while maintaining high performance and reliability.

Liquid cooling for servers and electronic devices uses dielectric fluids, suitable for direct contact with chips and electronic equipment, in the case of direct immersion cooling, or for cold plates applications. Cold plates are special components used in the liquid cooling of electronic components, made of metals with high thermal conductivity (typically copper or aluminum). The chip or electronic component that overheats is attached directly to the cold plate, and the heat is transferred to it by conduction. Inside, the coolant flows through special microchannel structures, which greatly increase the contact surface with the overheated metal. The liquid then absorbs the heat and, via a small pump, is pushed out of the cold plate towards a heat exchanger or chiller.

In addition to the superior heat dissipation efficiency of the heat generated by servers, liquid cooling also offers another key advantage: compactness, allowing for the creation of high-density computing structures in data centers while saving installation space. The Tempco range of brazed exchangers for liquid cooling in data centers therefore offers very compact dimensions, which allow for easy integration into CDUs inside racks or in-row architectures, which can serve up to 10 racks.

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.

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.
