Europe’s Air Quality Revolution in Modern Farming: How LONGWELL EC Fans Achieve a Win-Win for Energy Efficiency and Animal Health
In modern animal husbandry, air quality and energy efficiency are critical factors determining operational costs and animal health. Facing increasingly stringent environmental regulations and rising energy prices, achieving an efficient, energy-saving, and environmentally friendly ventilation system has become a common challenge for farming enterprises worldwide. Ningbo Longwell Electric Appliance Technology Co., Ltd. (LONGWELL), with its innovative EC fan technology and smart solutions, successfully helped a large European farm achieve a revolutionary upgrade in air quality, bringing unexpected economic benefits.

Background Challenge: The Dual Dilemma of High Energy Consumption and Excessive Ammonia
A large modern farm in Southern Germany, covering an area of 15,000 square meters, had long been plagued by its existing ventilation system. The enormous monthly electricity bill, reaching up to 30,000 Euros, was an unbearable burden for the farm owner. Even more concerning was the frequently excessive ammonia concentration within the farm, which not only severely affected animal health and growth but also led to stern warnings from local environmental authorities.

The original ventilation system used traditional AC fans, whose main problems were low efficiency and lack of flexibility. Regardless of day or night, summer or winter, the fans operated in a fixed mode, unable to precisely adjust airflow based on real-time changes in temperature, humidity, and ammonia concentration within the farm. This resulted in significant energy waste and challenges in air quality management.

LONGWELL’s Precise Diagnosis: Uncovering the Root of the Problem
Upon receiving the request for help, LONGWELL’s technical team quickly arrived on-site for a thorough inspection. Through in-depth and meticulous analysis, we found that the core of the problem lay in the inherent defects of the original AC fans: they were not only energy-inefficient but, more critically, incapable of on-demand airflow regulation. This “one-size-fits-all” operating mode meant the ventilation system ran at full speed even when high airflow was not needed, causing astonishing energy waste and failing to effectively control the accumulation of harmful gases like ammonia.
LONGWELL Solution: Smart EC Fan System, Opening a New Chapter for Farming
Addressing the challenges faced by the German farm, LONGWELL provided a tailor-made smart ventilation solution, centered on the deployment of our advanced LWBE3G560 EC centrifugal fans, complemented by a smart control system .
We deployed a total of 48 LWBE3G560 EC centrifugal fans. These fans belong to the “Plug fans” category, known for their excellent energy efficiency and controllability. Their main technical parameters are as follows .

Model: LWBE3G560-188PT-01
Voltage: 380V
Power: 3300W
Airflow: 16039 m³/h
Pressure: 1166Pa
Unlike traditional AC fans, the LWBE3G560 EC fans utilize advanced EC (Electronically Commutated) technology, enabling stepless speed regulation and precise control of airflow output. Combined with LONGWELL’s smart control system, we installed high-precision ammonia and temperature sensors, achieving true demand-responsive ventilation. This means the fans can automatically adjust their operating status based on real-time air quality and temperature data within the farm, ensuring an ideal air environment is maintained with optimal energy consumption.
Furthermore, we implemented a zone control strategy, dividing the 15,000-square-meter farm into different areas. Airflow was precisely adjusted according to the animal density and specific needs of each zone. This refined management completely resolved the previous “one-size-fits-all” ventilation mode, eliminating unnecessary energy waste.

Revolutionary Outcomes: A Dual Leap in Energy Efficiency and Animal Health
Upon project completion, LONGWELL’s smart EC ventilation system brought exciting results to the German farm:

1. Significant Energy Consumption Reduction: The farm’s monthly electricity bill decreased by 35%, saving the enterprise considerable operating costs. This directly demonstrated the LWBE3G560 EC fan’s excellent energy-saving performance.
2. Improved Animal Health and Productivity: Even more surprisingly, the animal growth rate within the farm increased by 8%, and the mortality rate decreased by 2.3%. This was attributed to the continuous and stable high-quality air environment, which effectively reduced the incidence of respiratory diseases and promoted healthy animal growth.
3. Environmental Compliance and Sustainable Development: Ammonia concentration was effectively controlled, and the farm no longer faced warnings from environmental authorities, achieving green and sustainable development.
The farm owner excitedly stated: “This is not just a ventilation upgrade; it’s an upgrade of the entire farming model! LONGWELL’s solution not only helped us save huge electricity bills but also made our animals healthier and more productive. This is a crucial step for our farm towards modernization and sustainable development.”
