New European regulations around energy efficiency have created a reaction among manufacturers of the ancillary industry, who despite their high investments in R & D, have been forced to adapt their products to the new requirements. Manufacturers of electric motors such as WEG, have fully endorsed this goal and have pleaded in favour of sustainability, investing in green products and innovting their technology with the aim of reducing consumption and improving efficiency.
Thus, not only do they invite their customers to save money, but also to support the environment conservation by reducing emissions.
In their web page, WEG show us how to save money by installing a frequency converter. Applications do not normally run at full load all the time, and the installation of a speed shifter can help save money by controlling the process speed and the adjustment of the specific load at any time. Pumps and fans are two of the most sensitive elements to these changes. To calculate the savings, WEG offer the user an energy savings calculator which is either available online or can be downloaded.
Although it may seem otherwise, especially considering the moment of crisis being experienced by the global industry, the replacement of an old electric motor by a more performant one, will result in significant savings that help pay back the investment in a few years, and in some cases even months. This tool for calculating the return on investment can also be found in the following link. It allows to calculate energy savings, return on investment, CO2 emissions reduction, and create reports and calculations for all motors installed in a site with just one click.
WEG Iberia, the Spanish subsidiary of WEG, are 15 years old and have announced their Spanish headquarters” address change. The new headquarters are in Coslada in Tierra de Barros Street, 5-7, and include a 6,000 m2 floor space and about 1,000 m2 for offices. The phone, fax and email addresses remain unchanged.
According to Zigor this installation is the “first solar plant of its kind connected to the State Grid,” and has an output of one megawatt, occupies 3.5 hectares and is located in the province of Imbabura, “which is one of the areas with higher solar irradiation of Ecuador “.
As a novelty, the power plant features a 1MW Sunzet Power Station, a Plug & Play solution housed in a 40” container that facilitates quick and efficient connection between the solar field and the grid and is delivered fully equipped according to the installations requirements. In this case, the plant was delivered with 8 Sunzet 125 MV inverters, the medium-voltage switchgears, medium voltage transformers and energy meters. In addition, smart concentration boxes Sunzet String Box have been installed allowing to monitor in real time the current of each string of solar panels through the Plant Monitoring System SCADA SWS-1000 designed and manufactured by Zigor. The scope of supply also included 4160 240Wp solar panels that make up the solar field (total 998.4 kWp), metal structures and wiring for the inter- connection of the whole plant.
The 1MW PV plant will generate clean energy, improve the quality of energy services and save millions of dollars in fuel and energy imports from other countries, in addition to reducing CO2 emissions considerably.
Zigor Corporacion, the company based in Vitoria-Gasteiz (Álava), has given technical advise on the plant ́s design and sizing, has overseen the installation work carried out by the local installer, commissioned the plant and trained service technicians operating the installation. In addition and as a result of the agreement with Valsolar Ecuador, the company has supplied all the necessary components for the solar plant construction, comprising 4,160 240Wp (watts peak) solar panels that make up the solar field (total 998.4 kWp).
