In the middle of the 1960s, the brothers Kristen and Kjeld Skov developed the first ventilation system. The Skov brothers were running the largest egg production facility in Scandinavia at the old manor house of Oestergaard Hovedgaard, and the idea of a ventilation system was born in connection with the erection of two new livestock houses.  Since then, new systems and products have been developed and today we are a world leader in our field. The Glyngoere headquarters have been expanded on several occasions and today there are more than 400 members of staff and in excess of 16,000 m² under roof.

Fully environmentally controlled ventilation:

The primary goals of effective poultry house ventilation are to remove excess heat and moisture and provide oxygen while removing harmful gases, thus maintaining air quality in the house. When house ventilation is set up incorrectly, the systems can struggle to achieve the primary goals and the performance and health status of the birds will suffer. A number of factors should be taken into account before designing the ventilation system, namely:

  • Stocking density (Number of rows and tiers)
  • Bird weights
  • Type of construction and insulation
  • Length and width of the building
  • Maximum and minimum temperatures
  • Humidity percentage
  • Optimal Climate All Year Round
  • For All Types of Farming, Layer, Broilers, Breeder etc.
  • Optimum Conditions for Birds
  • Reliable and Easy to Operate

SKOV’s LPV system is a classic low-pressure system for use in poultry production, which can be adapted to most poultry houses. The system is developed for the temperate parts of the world and comprises a number of components which together ensure optimal climate conditions for the animals.

In a Tunnel system, the air inlet is placed at the side or the house end and is clad with cooling pads or installed with high-pressure cooling. There are several types of air inlets for a tunnel system, and they can also be supplemented by cooling systems in the form of cooling pads or high-pressure cooling. To create an airflow in the house, i.e. cooling for the animals, gable fans are installed at the opposite end. In other words, the air velocity cools the animals, and the higher the velocity, the lower does the temperature feel. This is all controlled by a house computer that manages the ventilation system based on a series of inputs and settings. The computer is easy to use and includes all necessary functions.

SKOV’s Combi-Tunnel ventilation system is a negative pressure system for poultry houses. The system has been developed for tropical and subtropical climatic zones with daily and seasonal fluctuations of temperature. SKOV’s Combi-Tunnel ventilation system combines our LPV and our Tunnel systems and ensures optimum growth conditions for the animals even at very high outdoor temperatures.

There are a number of different ways to achieve your ventilation goals and Dynamic Automation, through years of experience, can assist in the most efficient and cost effective design to suit your particular area and house layout. The two common methods are tunnel or combi-tunnel ventilation. Contact us for expert advice that might maximise your production results.

Skov Controllers

There are many things to manage in modern poultry production, where the stocking rate in the house is high and exploited to the maximum. A precise and effective climate control is therefore necessary in order to ensure optimal conditions for the animals. 

SKOV has wide experience in developing user-friendly climate computers capable of handling both simple and advanced control tasks. All climate computers are modular, so they can always be adapted to the individual needs of the batch. We have worked hard to make the technically advanced simple, which is why the menus of the climate computer are designed with icons that make them easy to use.

Skov DA 1700 BlueFan

BlueFan – the next generation of wall fans

Fan combines a high airflow ratio with a high energy efficiency. This makes it the most powerful fan on the market. It excels in the unique airtight motorized shutter system. The DA 1700 wall fan is a flange-mounted corrosion-free fan with cone and motor-controlled
shutter. The fan is supplied in one version focused on low energy consumption and one version focused on maximizing air output. 

The DA 1700 is used in connection with Combi-Tunnel and Tunnel ventilation or as extra air outlets in connection with LPV ventilation.

Skov BF 50 BlueFan

SKOV launches a new wall fan in the BlueFan family called BF 50. The BF 50 is used in LPV, Tunnel, as well as in Combi-Tunnel houses for side mode and tunnel mode ventilation. The fan is available in stepless (0-100%) variants, traditional ON/OFF variants, as well as LPC variants for Dynamic MultiStep.

The BF 50 can replace traditional box fans as a one-to-one solution. It is a 50-inch box fan and thus fits into the existing holes upon replacement. Likewise, you can often reuse the existing electrical installation and controller.

Traditional box fans, made of galvanized metal, require replacements at regular intervals as they are exposed to the harsh environment of the livestock house


DA 75 R&P

SKOV has developed a new DA 75 Rack & Pinion winch motor for application in connection with the open/close function of doors in the tunnel opening. DA 75 is a series of very sturdy and reliable winch motors specially designed for regulation of inlets, flaps and now also tunnel openings in the ventilation systems. The design of the motors has all functions gathered in a single cabinet.

In connection with Combi-Tunnel ventilation, it has up till now only been
possible to make emergency opening through wall inlets which are
characterized by a smaller opening area. The newly developed DA 75 Rack & Pinion winch motor is now available in a 24V variant for installations where it is possible to make emergency opening of the tunnel opening. The length of the tunnel opening is typically 25-30 metres. This
provides a much higher rate of airflow and much better emergency ventilation

DA 175 actuator

SKOV has developed a new DA 175 actuator for controlling wall inlets. The DA 175 is available in several variations with a tensile force of 100kg, 150kg, 300kg or 600kg.

The DA 175 actuator is available as a variant with 24V, facilitating emergency opening via DOL 278A. Emergency opening can be performed steplessly or ON/OFF depending on the DOL 278A variant.

The DA 175 actuator is made of maintenance-free materials resulting in no maintenance costs once installed. For example, it contains no carbon brushes in the motor that require regular replacement. DA 175 is designed to be used in an aggressive livestock house environment, it can be washed (IP 65) and placed inside or outside a livestock house section

conditions in livestock houses with direct combustion.
The sensor is protected by a sturdy casing, and lies behind a carefully selected filter. The sensor ships with a connector and cable
solution that makes it simple to remove the sensor for cleaning and disinfection of e.g. livestock houses.
The sensor is placed in the middle of the house.

DOL 16 is a sensor designed to measure light intensity. It is intended for application in livestock houses but is also well suited for a number of industrial applications.

The DOL 18 electronic sub-pressure sensor is used in connection with climate and production computers, for climate monitoring among other things.

The DOL 18 electronic sub-pressure sensor can be
used for reading of the pressure in the livestock house and for generating an alarm in case of too low or too high pressure.

The DOL 26 is a complete range of 18 mm sensors. The mechanical design of the 18 mm DOL 26 sensor makes it ideal for inclusion in small applications with limited space.

Versions with full return of the cable are especially suited
to feed pans. The sensor has a very low power consumption in standby mode – and therefore several sensors can work in parallel on the same contactor. This renders control of cross auger installations possible. DOL 26 is particularly immune to EMI short-circuiting and overloading, i.e. the risk of burnt-out sensors due to installation errors is non-existent.

The DOL 40R series comprises three models with different functionalities.
The DOL 41R has no time delay, the DOL 43R has the option of delayed disconnection and the DOL 45R additionally has the option of delayed switchon. Two push button switches adjust he sensitivity of the sensor and the time with light diodes indicating when the switches are activated.

DOL 44R is a complete range of 30 mm capacitive feed sensors with relay output. The sensors have robust functionality and are easy to operate.
Settings are easily changed via two trimmers using a small screwdriver. DOL 44R has a high immunity to noise from electric communication (e.g. mobile phones) and transients (e.g. from motors and contactors).

The IP69K protection class offers the highest protection against water and other liquids, e.g. during cleaning of livestock houses. 

The plastic gland can be mounted in a silo wall for example by means of an internal locknut or from the outside by means of the enclosed flange.

There is also a range of spare parts that facilitate mounting and servicing of the capacitive sensors.
