Thermoregulating units in clean energy

19/05/2017

It happens often that new applications of the thermoregulating units that we develop to meet customers requests surprise ourselves too. The flexibility of this kind of thermoregulating equipment allows indeed to offer a fine temperature regulation and heating capacity modulation to apply in several sectors, such as chemical, pharmaceutical, composite materials and test benches.

A particular application we recently developed required special thermoregulating units for testing of an alternative energy production system using a Stirling engine.

Diathermic oil life span in thermoregulating units

27/03/2017

Diathermic oil is a heat transfer fluid highly employed in temperature regulation systems, due to its high boiling temperature at atmospheric pressure conditions, between 400°C and 500°C, and to its low freezing point.

These properties give diathermic oil an excellent thermal stability, making it a perfect substitute of water and vapor in heat transfer systems and thermoregulation, for applications involving temperatures in a wide range, between -115°C and up to 400°C, mostly without pressurized equipments. I would like to suggest the products of Therminol by Eastman, in the selection of a diathermic oil, due to the excellent performances offered and also supplying other kinds of thermal transfer fluids allowing to manage wide temperature variations with very low viscosity variations.

The working life span of a good diathermic oil in a thermoregulating unit is usually about 3-4 years, provided that design, engineering and building of the plant are made taking care of a series of characteristics:

– Right equipments sizing
– Proper materials selection
– Correct filling and start-up process
– Planned maintenance and periodical service during plant working life

Automotive test bench

21/03/2017

Even in car there are utilities:

  • cooling systems
  • servo systems for steering
  • power assistance to the brakes
  • air conditioning
  • start / stop systems

All these features allow you to enjoy a relaxed trip with more comfortably and safely, and of course they have to operate in all conditions, and must be tested.

How to do? typically the largest producers of components for automotive, have test and climatic chambers where make the component tests, subjecting them to the most severe conditions that will meet in reality.

Demineralized water, how it is thermoregulated?

15/03/2017

There are many application fields requiring demineralized water, in fact all of the applications where water must be softened and filtered and, in addition, it must have specific electrical conductivity properties, to be employed for example in cooling of electric and electronic components, power inverters or generators.

It may appear as a kind of fluid not needing particular cares, but also working with demineralized water involves a special attention in the selection of components aimed to get in contact with it.

Demineralized water has indeed a high level of acidity, excluding the employ of copper, highly exposed to the risk of corrosion in a short time.

Circulating equipments used in combination with demineralized water are usually realized in different materials, such as:

  • stainless steel
  • brass
  • bronze
  • plastics

Some additional technical infos can be found in this table:

Customized for this kind of application, in Tempco we realize special and personalized thermoregulating units, employing materials compatibles for use with demineralized or deionized water.

How to control temperature in pharma process

08/03/2017

Tempco temperature control unit are employed in many different field of application.

In the last few month we design thermoregulating units for many different production systems:

  • active principles
  • antibiotics
  • bulk
  • hyaluronic acid
  • drying of powder products

all of these needs reactors with precise up/down temperature settings and gradients.

Customers greatest difficult are related to reckon the heating/cooling capacity they need…Ok!

Here the simply solution in 5 points:

  1. capacity of the reactor, or the volume … better the quantity of product content to the maximum production
  2. type of product, consequently physical characteristics
  3. range of working temperature
  4. time of heating / cooling
  5. weight of the equipment (reactor, dryer etc …)

defined these 5 simple steps, with an Excel spreadsheet, or a calculator, the computation of heating power and cooling become a breeze.

And if you have any doubts, please contact our technical department, which provides you the support.

How to regulate the chocolate tempering temperature

22/02/2017

The production of chocolate is a very delicate and complex process, which needs precise levels of temperature, to achieve a high quality product.

One of the basic steps in the processing of chocolate is tempering, that explained in very simple terms is a pre-crystallization of melting chocolate, before the modeling, so as to obtain a stable product over time, which presents a good surface gloss combined with a right internal compactness.

To obtain these results the modern tempering machines use temperature control units, providing heating / water cooling, according to a pre-determined cycle, to precise temperatures, with very narrow tolerances (0.1 ° C). These cycles change on the type of chocolate, but all need for fine regulation of temperature.

The typical tempering cycle passes through 3 stages of temperature:

  • first cooling of the chocolate mass
  • second cooling
  • post heating

The levels of temperature and time are typically between 45°C to 30/32°C and all the steps are verified with appropriate instruments which verify the grade of chocolate tempering.

Chillers -30°C in pharma industry

10/02/2017

Recently in Tempco we’ve developed a refrigeration solution for near-cryogenic temperatures supplied to a customer in the pharma sector, aimed to cool down to -25°C the reactor employed in the production of the active ingredient of an innovative aerosol.

chiller pharma Tempco

After a careful evaluation of the overall process, we came with the proposition of two alternative solutions:

  • A liquid nitrogen cooling system
  • A classic compressor chillers solution

The solution using chillers was the preferred one, due to its technical advantages and the easier management. We agreed with the customer to develop a system employing two chillers working in parallel, each one achieving 75% of the total duty required.
The cooling capacity of each chiller is -30°C, and an automatic regulation system of the condensation ensures the best process efficiency in every season, an essential requirement because the plant is always operating.

The full stainless realization steel has a special insulation for extreme low temperatures. A storage and distributing skid was built inside the building of the customer, providing the reactor the non-freezing solution, and equipped with:

  • Storage tanks
  • Redundant pumps
  • Monitoring and management centralized system

The remote management from a control-room allows monitoring and piloting of both chillers and pumps, with the possibility to manage alarms in order to ensure maximum productivity and to avoid expensive downtimes.
