The food & beverage industry is a massive end-user of heat exchangers, for applications such as thermoregulation of production goods or heat recovery. Special executions to meet the hygienic requirements of the sector are the ABC here.
Equipments are indeed exposed to frequent cleaning cycles, using aggressive and potentially corrosive chemical agents. The corrugation on plates creates several grooves and recesses where persistent residual biofilms can stuck, that must be removed in order too avoid growth and proliferation of microbes, fungus and bacteria.
Once in a while Italy rules as a best practice in terms of energy efficiency among SMEs. Is good to read in this interesting and accurate article about the Energy audit model implemented by the Italian government, an effective tool to unlock great energy efficiency potential in Europe, considering that SMEs are the heart of European economy, representing 99% of all businesses in the EU.
In Italy the Article 8 of the current Directive 2012/27/EU, also know as Energy Efficiency Directive (EED), has been ratified with the Legislative Decree n. 102 of 04/07/2014. The European EED defines ‘energy audit’ as a systematic procedure with the purpose of obtaining adequate knowledge of the existing energy consumption profile of an industrial or commercial operation, also identifying and quantifying cost-effective energy saving opportunities.
Hot season is coming, cooling plants are beginning to get some difficulty … preventive maintenance helps to avoid problems and to increase production efficiency.
The increase in efficiency includes, in my opinion, two important aspects:
- Increase the productivity of a plant
- Reduce plant management costs
Surely a preventive maintenance action of heat exchangers, which involves washing and regenerating, achieves both goals.
- You can increase your plant’s productivity, as the “cooling / heat exchange” system will reach and maintain the required temperature levels more quickly.
- At the same time, this higher speed saves energy (electrical / thermal) needed to reach and maintain temperature levels, without dispersion or obstacles.
We have already started to make scheduled maintenance. The service division is equipped with spare parts for quick intervention in case of urgency.
You can contact us to assess the efficiency level of your systems and the costs for preventive maintenance.
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.
Special industrial applications are the perfect field to take advantage of the extreme flexibility of Tempco’s special Thermoregulating units.
An example is the special custom solution we designed and engineered for application in a test bench for extreme high-performance motors, engines to be employed in competition and racing cars.
We developed for a specific customer a diathermic oil thermoregulating unit for high-temperatures up to 300°C, with fine temperature regulation.
We’ve already faced the issue of fouling in heat exchangers in the past. Especially in heat recovery applications from high temperature exhaust gas, from engines and boilers, the deposits of carbon dust and unburned fuels stick to internal surfaces of both the engine and the heat exchanger.
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
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.
Tempco from many years, supports this application field, providing special thermoregulation unit that simulate the extreme conditions.
Temperatures from -30 ° C to + 300 ° C, allow to simulate the operating conditions to producers of
- aircraft electronic equipment
- conditioning systems
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
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.
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
- 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:
- capacity of the reactor, or the volume … better the quantity of product content to the maximum production
- type of product, consequently physical characteristics
- range of working temperature
- time of heating / cooling
- 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.
