At the end of June 2011, our specialists started work on the modernization project of the Daugavpils branch of the fish processing plant "Latis", where the largest sauleskolektors.lv system in Latvia was installed until 2011.

In the food industry, hot water is often one of the most important components in the production process. Consequently, water heating is also an important item of expenditure in the balance sheet. With this in mind, the plant's management decided to reduce this cost item by installing a solar collector system to enable the use of solar energy in the production process.

It should be noted that the factory must comply with certain sanitary standards during the production process. For example, containers must be washed with hot water of a certain temperature, the premises also, not to mention the production equipment. Therefore, when installing this system, the sauleskolektors.lv team had to take into account a number of specific requirements that are relevant in the food industry.

As the production process takes place in several shifts, water is consumed not only by the equipment, but also by people who (after work) must be able to wash themselves. However, as many people do this at the same time, there must be enough hot water. The installed solar system also helps to ensure this.

The factory consumed an average of 6 tons of hot water daily for various household and production needs. At the factory, the water was previously heated by electric boilers and instantaneous heaters, which are no longer economical today. The money spent on electricity so far after the system has been installed can be used for other development purposes.

After researching the situation and performing special computer simulations, as well as anticipating the factory development plans, an optimal engineering solution was developed. The facility has 30 flat Thermo | Solar solar collectors in three separate sections on the roofs of the factory. The water system has been changed and arranged, as well as an automated solar heat storage and distribution system has been created.

In order to make the overall hot water preparation system even more efficient, we also created a system for accumulating heat produced in the production process from fish freezers.
