Dairy farm fans
Dairy ventilation systems reduce heat stress by air destratifiers.
Vertical, square fans are dairy ventilation systems for use in cutting edge agriculture applications. Statically and dynamically balanced propeller; a cast aluminium propeller hub offering the best possible protection of bearings; oversized and permanently sealed bearings for a long and trouble free service life; belt drive for lowering propeller speed and noise; and a high performance electrical motors. The primary use of large circulation fans in livestock housing is to provide comfort cooling to the animals. For this very purpose, the MFS fan series is designed to provide the maximum cooling footprint at animal level.
Vertical fans for Dairy Ventilation Systems
The airspeed footprint is defined as the area in which the average airspeed exceeds 2m/s. The airspeed is measured at a level 1m above the ground when the bottom of the fan is mounted 2.7m above the level of the ground. Measurements were taken in an empty room. Actual airspeed might be influenced by objects such as animals and structural elements

CMP impianti VS fans
VS fans are axial destratifier with gear motor, extraordinarily functional and cost convenient. The particular feature of this series of products is the axial unloader, a patented component added to the mechanical part of the fans in order to eliminate the friction generated by the weight of the impeller and blades and increase their robustness. The VS fans are the traditional alternative to the ZEFIRO line and well suited for heavy-duty work situations.
- Available in 5 different diameters : 3,4, 5, 6, 7 mt
- Propeller equipped with 5 blades (4.38m: with 8 blades)
- Variable speed control by VFD and EC (permanent magnet ) motor
- Strong aluminum airfoil shaped blades
- Extremely high energy efficiency
- Very high m3/h /W (high cfm per watt)
- Very low noise level
- Reduces heat stress and improves comfort
- Easy to install, in new or existing structures
Flexable use fan is VERTIGO-SL
VSL VERTIGO are axial fans with gear motor, extraordinarily functional and cost convenient. VSL VERTIGO fans are the traditional alternative to the VERTIGO brushless engine and well suited for heavy-duty work situations. The steel mounting frame with position locking mechanism provides 90° rotation, allowing it to work horizontally or to be tilted as required from 0° to 90°: the aim is to optimize the airflow even in the most complex situations

CMP the brushless ZEFIRO fans
The Brushless (permanent magnets) engine which deploys an on-board mechanism for automatic and independent speed control. This kind of innovation makes it possible to no longer use the gear motor present in asynchronous motors, so as to reduce the presence of mechanical parts subject to wear. The main benefits are the reduced use of maintenance, greater efficiency and lower energy consumption. ZEFIRO fans are fully designed and developed inside our technical department, including the study of the die-cast aluminium casing and the eye-catching design. The phonometric tests done at the motor prove that it emits a noise lower than 35dB and it amounts to only 64dB when it is equipped by blades.
MOTOR PERMANENT MAGNETS Gearless technology design and manufacturing CMP expertise. Highest levels of performance and energy efficiency. No reducer, elimination of maintenance, Noise reduction.
ONBOARD MOTOR CONTROL More compact and lighter onboard inverter controller with range power input voltage 1 or 3 phase 50/60 Hz. Speed and

Temperature Humidity Index
Temperature Humidity Index (THI) is a measure that has been used since the early 1990s. It accounts for the combined effects of environmental temperature and relative humidity and is a useful and easy way to assess the risk of heat stress.
Where THI Is Used
Research has identified THI values above which heat stress begins. These THI values vary between the different livestock species of interest and within the same species, they vary for the different classes of animals.
Normally THI is used in cattle breeding, both in dairy and in meat cows. Cows are indeed very delicate animals, which suffer a lot of heat stress with serious consequences on their productivity and on the quality of their final output. This happens because a large part of the energy deriving from food is used to maintain a constant body temperature and it is therefore not destined for other activities (milk production, growth, pregnancy, fattening, etc.).
How Do I Calculate THI?
Heat stress is caused by a combination of temperature, relative humidity, solar radiation, air movement, and precipitation. The majority of studies on heat stress in livestock focus on the two main environmental stressors: temperature and relative humidity (RH).
There are different formulas to calculate the THI, but one the simplest and most common is the following: formulas
THI =0.8*T + RH*(T-14.4) + 46.4
where T = ambient or dry-bulb temperature in °C and RH=relative humidity expressed as a proportion i.e. 75% humidity is expressed as 0.75.
The water vapor concentration of the air is important since it can drastically reduce the ability of the animal to use evaporative heat loss through the skin and lungs.
Cattle can tolerate much higher temperatures at lower relative humidity because they are able to dissipate excessive heat more effectively by sweating.
However, during hot and especially humid conditions, the natural ability of cattle to dissipate heat is compromised due to the lowered ability to utilize evaporative cooling.
