Modern animal husbandry is characterized by numerous important aspects. Each species of animal requires a very special housing environment in order to be kept in a manner appropriate to the species and productive from an agricultural point of view. Whether cattle, horses, sheep or pigs, it is important aspects such as the barn design itself, but also a sufficient supply of fresh air through modern barn ventilation, that contribute to modern, contemporary and species-appropriate animal husbandry.
But the more animals are kept in a barn, the greater the associated risks. High germ and ammonia loads, which are caused by the everyday use of the stable area, can quickly lead to the outbreak of diseases if there is insufficient fresh air supply and stable hygiene and thus endanger the health of the animals on the one hand and noticeably reduce the productivity of animal husbandry on the other.
We at BLEMO® Frequency Inverters have addressed this issue and developed the ER24G-V4. This inverter has a bypass switch and, if required, an additional setpoint switch and potentiometer. In the event of a defect in the frequency converter, the fan motors in the barn can be immediately and easily switched to direct mains operation, so that the ventilation system, which is vital for the animals, continues to operate. This will protect your animals! Due to its high protection class IP65 without external fan, this inverter is particularly suitable for harsh environments.

It is estimated that the measures in the work programme could lead to total annual final energy savings of more than 260 TWh in 2030, equivalent to a reduction in greenhouse gas emissions of around 100 million tonnes per year in 2030. By 2030, the energy industry is to cut CO2 emissions by at least 61 percent compared to 1990 levels. That’s another 30 percent or so from the current level (2020).
Certain products will have to meet certain minimum energy efficiency requirements from 2021. The aim is to reduce the negative environmental impact during the product life cycle through targeted measures adopted by the EU.
In this context, the IEC 61800-9-2 standard defines the IE classes (International Efficiency) for frequency inverters and also the IES classes for power drive systems (motor and drive combined / International Efficiency System). The ecodesign requirements should harmonise the energy efficiency requirements for electric motors and speed governors throughout the Union in order to contribute to the smooth functioning of the internal market and improve the environmental performance of those products.

A variable frequency drive or frequency inverter is a type of motor control that drives an electric motor by varying the frequency and voltage of its power supply. In addition, it is able to control engine start-up and shut-down during starting and stopping, respectively.
Even though the drive controls the frequency and voltage of the power supplied to the motor, we often refer to this as speed control because it results in an adjustment of the motor speed.
There are many reasons why we should adjust the engine speed.
In addition, today’s AC drives integrate networking and diagnostic capabilities to better control performance and increase productivity. Energy saving, intelligent motor control and the reduction of peak current consumption are therefore three good reasons to choose a frequency inverter as the control system in any motor-driven system.
The most common applications of a frequency inverter are the control of fans, pumps and compressors. These applications account for 75 % of all drives operating worldwide.
Soft starters and mains operated contactors are other, less sophisticated types of motor control. A soft starter is a semiconductor device and allows a smooth ramp-up to full speed when starting an electric motor.
A line-powered contactor is a motor control that applies full line voltage to an electric motor.
BLEMO® has specialized as a manufacturer in frequency converters and soft starters. You receive an extremely high-quality frequency inverter that is individually tailored to your requirements. Every single frequency inverter undergoes comprehensive testing before leaving the factory. Our experts focus on every detail of drive optimization and are always at the cutting edge of technology. The latest developments often go to our account. BLEMO has a wide range of frequency inverters and softstarters, but you get much more than the frequency inverter. You have access to our application know-how and various maintenance services to keep your systems running optimally throughout the entire life cycle of your frequency converters.
We offer you the best possible components and full flexibility so that you can tailor the system performance exactly to your application. An important aspect of this flexibility is the ability to use your frequency inverters with all common motor technologies. This allows considerable savings on spare parts held in stock and on retrofits.
A frequency inverter can vary the power output according to the energy demand of the driven device, thus saving energy and optimizing power consumption.
The frequency converter can drastically reduce energy consumption compared to direct operation on the mains, where the motor runs at full speed regardless of demand. The use of a frequency converter typically achieves electricity or fuel savings of 70% %. The roll-on effect means that the use of variable speed drives also reduces NOx emissions from the systems in which they are installed and improves their carbon footprint.
There isn’t one. All these names refer to the same device.
There are many different types of frequency converters as they are widely used in the industry. There are both single-phase and three-phase frequency converters for a wide range of applications. Differences in each type of frequency converter include the various methods of frequency and voltage control and harmonic mitigation technologies.
The three main variable frequency generation techniques used in frequency converters are pulse width modulation (PWM), current source inverters and voltage source inverters. PWM technology is the most common. PWM technology requires that the inverter power electronics of the frequency converter – transistors or insulated gate bipolar transistors (IGBT) – generate the correct voltage level by constantly switching on and off. By controlling and varying the pulse width, pulse width modulation changes the output frequency and voltage.
At the beginning of the season, the BLEMO® team presented the C Juniors of SV Fischbach 1912 e.V. with a new set of jerseys. We are proud to be a part of the team and wish the team much success in the games.
Coach Christoph Ketelaer is particularly pleased that he was able to find a new sponsor.
