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.

Gas turbines are extremely sensitive to fluid conditions, in terms of temperature, fluid density, and thermal profile stability. In many industrial applications (power generation, oil and gas, LNG, hydrogen-ready plants), precise control of gas temperature is essential to improve efficiency, reduce operational instabilities, and protect the equipment during transient conditions. This is where the Gas Turbine Performance Heater is involved.

A Gas Turbine Performance Heater is essentially a heat exchanger designed for gas preheating (air, fuel gas, process gas), with a controlled ΔT, high reliability, and often undergoing high pressure and continuous service. Typical applications include fuel gas conditioning, intake air heating, and heat recovery systems from oil/hot water/waste heat recovery circuits.

Tempco proposes PCHE exchangers as particularly suited to this role, as they offer significant key advantages over traditional shell-and-tube solutions:

• Extremely compact
• Resistance to high pressures (tens/hundreds of bar)
• Perfect thermal stability even with rapid gradients
• Minimal fluid accumulation → safety + fast response
• Channel geometry optimizable upon the actual operating point

In performance-driven turbine applications, this makes the difference.

PCHE + Turbine: a smart technical marriage
As a performance heater, the PCHE allows:

• very precise control of the inlet gas temperature
• low pressure drops (if properly designed)
• easy integration into compact skids
• reliable operation even in:
  ◦ offshore environments
  ◦ frequent start/stop cycles
  ◦ severe conditions (H₂ blend, dry gases, LNG boil-off)

When the focus is performance + reliability, the PCHE is often the most engineered choice, not just the most compact.

A double advantage is therefore achieved when increased performance is achieved by implementing a heat recovery system, and this is where the application becomes very interesting, when the PCHE is served by:

• heat recovery circuits
• jacket water
• hot oil
• process waste heat

The result is an increase in the overall efficiency of the system, a reduction in auxiliary consumption, and improved operational control of the turbine.

Tempco therefore positions itself as a strategic technology partner for the development and implementation of this type of application, providing not only the technology but also support for the engineering, in defining the actual duty cycle and verifying turbine-side pressure drops – a highly critical issue – and then ensuring the integration of PCHEs into complete skids and technical dialogue with EPCs and turbine OEMs. The PCHE is not a standard component, but a solution tailored to the plant.

In conclusion, the use of PCHEs as Gas Turbine Performance Heaters represents a natural, highly innovative evolution of high-performance applications in the oil and gas sector, effectively addressing the needs for compactness, safety, and control. Representing a perfect example of applied thermal engineering as a special and customized, non-standard solution.

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.

Hydrogen is becoming one of the most promising solutions for a sustainable energy future. Refueling hydrogen vehicles requires precise temperature management to ensure safety and efficiency. PCHE heat exchangers offer an innovative and reliable solution to these needs.

Hydrogen refueling is challenging for a number of reasons: hydrogen must be compressed to extremely high pressures (up to 700 bar) to be stored in vehicle tanks. During this process, a lot of heat is generated; if it is not managed, refueling becomes slower and less efficient. This is where PCHE heat exchangers technology can be applied.

Several characteristics make PCHE exchangers so special, ideal to solve the challenges posed by hydrogen technologies. What are PCHEs? Imagine a compact and robust device capable of rapidly cooling fluids. Their usefulness in hydrogen applications has several aspects:

• They easily handle high pressures.
• They are small, so they take up less space at refueling stations.
• They cool the hydrogen quickly and precisely, speeding up the refueling process.

In the specific case of hydrogen refueling stations, the operation of PCHEs therefore adds value to a series of crucial steps to ensure the system’s efficiency and operational safety:

• During refueling, the hydrogen is compressed and then cooled by the PCHEs before entering the vehicle’s tanks.
• This process prevents the gas from overheating, making the process safer and faster.
• Simply put, PCHEs help refueling stations operate more efficiently, allowing drivers to refuel in just a few minutes.

To give a practical example, a refueling station equipped with PCHEs can refuel more vehicles in less time. This brings a series of key advantages:

• Time savings: less waiting time at the refueling station.
• Improved reliability: the system does not overheat and always operates at its best.
• Reduced operating costs, thanks to their energy efficiency.

Looking to the future of green mobility, the rise of hydrogen vehicles requires increasingly efficient refueling stations. PCHEs will be a key enabler of this growth, as their unique technology offers the ideal solution to overcome the challenges of hydrogen refueling. Thanks to their efficiency and reliability, they represent an investment in a greener and more sustainable future.

Why preheat rolling rolls?

1. Thermal shock reduction. Rolling rolls are subject to rapid temperature changes when they come into contact with the red-hot metal. Adequate preheating reduces thermal stress, preventing cracks, deformations, and premature wear.
2. Increased dimensional stability. Temperature variations affect the expansion of the rolls, potentially causing misalignment and defects in the rolled product. Maintaining the rolls at a uniform temperature before starting the lamination process ensures more precise rolling and reduces production waste.
3. Product surface quality. A roll with uneven temperature can cause imperfections on the surface of rolled steel, such as marks or waviness. Preheating ensures more uniform contact and a high-quality finishing.
4. Optimized energy efficiency. Without preheating, the initial contact between the cold roll and the hot metal leads to heat dissipation and increased energy requirements to maintain the suitable operating temperatures. Preheating units reduce this heat loss, improving process efficiency.

Tempco Solutions: Electric Heating Units
Tempco designs and manufactures electric heating units specifically for preheating rolling mill rolls.
These systems offer:

• Precise temperature control, with automated adjustment
• Uniform heat distribution, avoiding temperature differences along the roll
• Reduced start-up times, increasing plant productivity
• Compact and efficient design, with customized solutions based on customer needs

The adoption of Tempco control units therefore represents a strategic investment for rolling mills aiming to improve reliability, product quality, and operational sustainability.

The green transition and energy efficiency are key themes underlying MicroChannel Devices’ technological offering, making the company an iconic example of the ongoing shift toward sustainable innovation paradigms for the future of everyone – companies, manufacturing, and communities.

As CEO Alessandro Vaiarelli explains, MicroChannel Devices is an innovative SME founded in 2020 as a spin-off and evolution of the family business STV, leveraging the expertise and experience built over 60 years in the automotive and electronics sectors. Vaiarelli then lucidly illustrates how Italian companies can regenerate themselves by investing in innovation, which in the case of MicroChannel Devices meant specializing in the development and production of microchanneled devices that find their ideal application in the energy transition market.

Specifically, thanks to the valuable synergy and collaboration with Tempco, the company produces PCHE exchangers (printed circuit heat exchangers) using innovative technologies such as diffusion bonding, or solid-state welding, which produces a heat transfer pack with extremely high structural strength, and a process called chemical etching, a photochemical etching technique similar to that used in electronics for chip production. This process in particular allows for the creation of heat transfer circuits with extremely high thermal transfer efficiency, with highly customized layouts and the possibility of building exchangers even in multi-stream mode.

The characteristics offered by these innovative plate heat exchangers make them the ideal technological solution for all new applications in the hydrogen supply chain, in nuclear energy with fourth-generation Small Modular Reactors, as well as for cold plates in direct-to-chip liquid cooling for data centers that will serve future artificial intelligence applications, as well as in the oil & gas and LNG sectors.

But there are also applications which are not necessarily involving an energy recovery task, but they necessarily require the cooling of the served production process. In this specific case, free flow exchangers are employed in the pulp and paper industry which includes sectors that are processing paper pulp, and therefore, clearly before paper sheets are shaped, involving the use of water full of suspended solid particles.

Another similar application where we use several of these exchangers is related to the plastic grains production industry. Even in this case, the process water that must be cooled is highly dirty and full of suspended solid particles.

These are plate heat exchangers, and they present a peculiar construction, as we have already seen. Someone objected, well having no contact points between the plates, what level of differential pressure they can stand.
Clearly, they can stand lower differential pressures compared to classic plate heat exchangers. That’s the reason why, in this case, plates have a higher thickness, starting with 0,8 or 1 mm, depending on the size of the plate. They are usually quite big plates and they have low resistance, and thus low design project pressures arriving up to PN6, PN10, rarely PN16.

But, after all, the kind of applications they are employed in never require high working pressures, usually limited to the circulating pressure of a centrifugal pump, and that means 3 or 4 bar.
