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.

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.

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.

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.

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.

Tempering and thermoregulation: the secret behind crisp and shiny chocolate

21/11/2025

In chocolate production, after the cocoa bean roasting, refining, and conching production steps discussed in previous posts, tempering represents the true art of pastry making, and here too, precision and temperature control is essential.

During tempering, the chocolate is heated, cooled, and then reheated following a very precise thermal cycle (45°C, 27°C, and finally 31-32°C). This process is essential for stabilizing the cocoa butter crystals in their most stable form, which guarantees a shiny, crispy, and heat-resistant final product.

Here, once again, thermoregulation units play a crucial role, ensuring that each step occurs at the correct temperature and with optimal timing. Poorly executed tempering can cause aesthetic defects, such as dull surfaces or streaks, and compromise the chocolate’s consistency. Precise temperature control, on the other hand, allows for a visually appealing product that is pleasing to the palate.

In this sense, the tempering phase is truly the touch of class that makes the difference in chocolate production.
