Brazed plate heat exchangers for high pressures up to 140 bar

20/02/2026

Brazed plate heat exchangers represent an extremely compact and efficient solution for heat transfer applications where space is limited and high performance are required. The standard version of these exchangers is designed for operating pressures up to 30 bar, but for more demanding applications, Tempco offers special high-pressure versions, with models capable of reaching 70, 100, and up to 140 bar design pressures.

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.

High efficiency exchangers for liquid cooling in AI/HPC data centers

13/02/2026

The exponential global growth in computational capacity is driving the energy consumption of high-power chips. In AI and HPC (High Performance Computing) data centers, increasing power density is pushing air-cooled systems to their physical limits. On the other side, liquid cooling technology, which until recently was marginal, is rapidly becoming a core infrastructure, offering the significant advantage of ensuring thermal efficiency hundreds of times greater than traditional air cooling.

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.

Thermal control unit for radiators test bench in Dallara Automobili

06/02/2026

Dallara is a historic Italian manufacturer of racing cars, true gems on four wheels that have shaped the history of Made in Italy motorsport over the years. The company was founded in 1972 in Varano de’ Melegari, in the province of Parma. In the high-performance world in which Dallara Automobili operates, extreme attention to detail makes the difference, and this also applies to cooling and thermal control.

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.

Air/water heat exchanger for thermoforming in the medical sector

30/01/2026

We recently supplied an air/water heat exchanger with a special ElectroFin treatment for a medical equipment production line, specifically for medical tubing.

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.

New monitoring requirements for Legionella prevention

23/01/2026

The problem of Legionella has sadly returned to the forefront in the final weeks of 2025 in Italy, so we believe it’s important to take an opportunity to revisit the topic of Legionella prevention and control, which, in terms of thermal management, is closely related to systems using evaporative cooling towers. These cooling systems are equipped with a series of measures to prevent Legionella, such as self-draining tanks to prevent water stagnation, in addition to water treatment systems with additives that reduce algae and bacteria.

The Italian regulatory landscape on this topic has undergone a significant transformation in 2025: Legislative Decree 102/2025, which came into force on July 19, 2025, made mandatory certain Guidelines drawn up by the Ministry of Health in May 2015. The new obligations for prevention and control established in the Legionella Decree 2025 include:

  • Mandatory monitoring activities. Activities are now classified according to a Priority code. Water monitoring is now mandatory in facilities beyond the previous regulations, such as hotels, sports centers, and restaurants.
  • Preparation of the Water Safety Plan (PSA). The Water Safety Plan (PSA) is a mandatory risk assessment and management model for managers of internal building water systems.
  • Appointment of the Internal Water Distribution Manager (GIDI). For Priority facilities, the role of the Internal Water Distribution Manager (GIDI) has been introduced. The GIDI is responsible for the building’s internal drinking water system and must be appointed. He or she is responsible for verifying that analyses and the PSA are performed.

Finally, penalties have also been increased, with fines of up to 30.000 euro for failure in compliance with monitoring parameters.

Waste-to-energy and high-efficiency thermoregulation in circular economy

16/01/2026

Tempco is very pleased to share a new application case that combines industrial thermoregulation and the circular economy. Our TREG diathermic oil thermoregulation unit has been chosen for the pilot site of a major European project, installed at the end customer’s site in the Turin area.

The project aims to transform waste treatment into an advanced energy process: increasing biomethane production while simultaneously converting non-recyclable waste into syngas (gas mixture obtained from the gasification of biomass or carbon-based waste), through thermochemical processes such as gasification and pyrolysis.

For these processes, heat regulation is critical: the heat supplied to the process must be stable, precise, and available at high temperatures. The Tempco control unit is therefore designed to ensure the required temperature regulation with maximum levels of safety and operational continuity of the system.

Our TREG meets these requirements precisely:

  • It works with diathermic oil at high temperatures, ensuring proper thermal decomposition of the materials.
  • ATEX certification, essential in environments with potentially explosive atmospheres.
  • Remote control, which allows for remote management of process parameters, reducing on-site interventions and increasing operational continuity.

From waste to Syngas: a closed cycle
TREG’s seamless integration into the project therefore represents a concrete example of circular economy applied to energy, with a green perspective and fostering sustainable energy transition:

  • Waste becomes a resource: materials that were previously a disposal cost are now transformed into an energy-rich gas.
  • The district becomes more self-sufficient, thanks to a process that recovers value from flows considered to be at their end-life cycle, achieving circularity.
  • Lower emissions and greater efficiency, because high-temperature thermoregulation makes the entire conversion cycle stable and reliable.

Scheduled service, a smart choice for the lifecycle of Tempco thermal machines

19/12/2025

Thermal systems often operate under continuous working conditions, with intense cycles and thermal load variations. Even the most robust unit, without scheduled maintenance, sees its performance decline over time: pumps lose efficiency, exchangers get dirty, valves derail from setpoints, and fluids get degraded with time and operations.

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.

Image showing components of a temperature control unit, for which scheduled maintenance is essential for operational continuity.

 

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.

Efficiency and operational continuity: original spare parts make the difference

12/12/2025

Taking care of industrial production plants means choosing original spare parts, and this is a general rule. Specifically, in thermoregulation, cooling, and energy recovery systems, each component works in synergy with the others: pumps, valves, heat exchangers, heating elements, controls, sensors. Using an incorrect or uncertified spare part can seem like a minor detail… until the day the machine breaks down.

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.

Image showing some plates as original spare parts for heat exchangers, the choice of which is crucial to ensuring efficiency and operational continuity.

Image showing some gaskets as original spare parts for heat exchangers and thermal machine components, the choice of which is crucial to ensuring efficiency and operational continuity.

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.
