H�jer FarmTech
EUR Clima Constant is a system for the cooling or heating of ventilation air. Cooling or heating applies subsoil water which is pumped through a heat exchanger which is installed in connection with the air intake to the livestock housing. Alternatively, the system can be established as a closed circuit with heating/cooling hosing set in the ground. Due to a stable temperature in the subsoil water/soil of 8-9 degrees C, the temperature in the fresh air can either be lowered on warm days or increased on cold days. The comfort of livestock and personnel can thus be improved all year and the energy requirements for heating in the winter months can be reduced. Clima Constant is manufactured by Bovema S-air B.V. in Holland and the dealer is Hans H�jer FarmTech A/S.
EUR Comfort 500 intake, type 230/35, is a newly developed air intake for pig houses. The air intake is made of stainless steel and is positioned immediately above the livestock area, for example, in the covered zone in a piglet pen. By introducing the fresh air close to the pigs, the air volume can be reduced by 20-50% in comparison with ventilation systems in which the air is added via a diffuse air intake or via shutters. In this manner, the size of the ventilation system can be reduced - and both power consumption and odour emission can also be reduced.

H�jer FarmTech
Lodour 50+ Air Purifier has been developed to reduce odour emission from poultry and pig housing. The purifier is constructed from knockproof polypropylene panels. The actual purifier unit consists of a filter element made of propylene and a sprinkling system. During the purification process, the ventilation air is carried by a ventilation channel from the livestock housing and through the filter element which is sprinkled with water. The biofilm which grows on the filter collects the odour particles. Lodour50+ can be integrated with the ECO95+ which is applied for the removal of ammonia from ventilation air. Lodour50+ is manufactured by Bovema S-air B.V. in Holland and the dealer is Hans H�jer FarmTech A/S.

The filter consists of a cassette based stainless-steel module with an integrated pressure chamber, filter material consisting of various types of wooden rods and wood chips, impregation material for the promotion of biological activity within the filter, plus a sprinkler system for the maintenance of a suitable humidity in the filter material. The ventilation air is passed through the pressure chamber and through the filter unit in which both odour and ammonia emissions are reduced. The HL-Biofilter, type HL-245/160 is manufactured by HL-Biofilter in Germany and is marketed by Rexlan Europe ApS.

Scan-Airclean ApS
Central Airclean System is a central air purifier for the reduction of odour and ammonia emissions. The system is installed in a cleaner housing in the roof construction of the livestock buildings. The cleaner housing is constructed of lightweight plastic modules. The air purifier is a two-stage system consisting of two vertical filter walls which are sprinkled with a purification fluid. In stage 1, the filter is sprinkled with an acidic water solution that removes ammonia and, in stage 2, the filter is sprinkled with pure water for the reduction of odour emission. The ventilation air is led to the cleaning housing via a central ventilation channel in the loft area. The Central Airclean System is manufactured by Stienen, Inno+, ITB, Holland and Scan AirClean A/S and is marketed by Scan-Airclean A/S.
Central Climate Control System is a ventilation system that is applied in connection with a central exhaust channel. The system consists of pressure stabilized SGS fans which are positioned between the central exhaust channel and the air exhaust or an air purifier plus up to 10 AQC exhaust units which are positioned between the stall sections and the central exhaust channel. The SGS fans are frequency regulated and the performance of the AQC exhaust units is further enhanced by guage wings which register the actual air replacement in the individual livestock housing section. The Central Climate Control System is manufactured by Stienen Bedrijfftselectronica B.V. in Holland and is marketed by Scan-Airclean A/S.
DK Temperature Control System cooling/heating system is a system for the cooling/heating of ventilation air. Cooling or heating is effectuated by water circulating through approximately 1,000 metres of plastic hosing which is buried at a depth of 2 - 4 metres. The water circulates via a number of heat exchangers which are positioned in the gables at loft level in the livestock housing. The temperature of the air intake can be retained between +8 and +18 degrees C all year round instead of the normal -10 to +27 degrees C. With a more constant temperature in the air intake the air exchange rate can be reduced by half, thus reducing energy consumption and odour emission and improving productivity and general welfare. This Temperature Control System is manufactured by Inno+ B.V. in Holland and is marketed by Scan- Airclean A/S.

SKIOLD
SE Evapocool is a high pressure cooling system for livestock housing. The system consists of a high pressure pump with V-belt drive and a pipeline system with spray nozzles. The V-belt drive means that pump revolutions can be reduced thus reducing wear and noise from the pump. The tips of the nozzles are constructed so that they can be dismantled and cleared of eventual lime deposits. By spraying water in the livestock housing, the temperature is lowered and dust is subdued. The SE Evapocool is manufactured by Pro-Air and marketed by SKIOLD A/S.

Skov
Skov Biological Air Purification is a newly developed modular based concept for air purification. The system consists of a number of modules corresponding to the volume of ventilation air to be purified. Each filter is constructed as a pre-fabricated unit with a purification capacity of 39,000 m� ventilation air. The actual filter is a two-stage filter consisting of vertical units which are sprinkled with water. Ammonia and odour particles are reduced in both filters whilst the greater amount of dust is removed in the first stage.
DA 1500 ceiling vent LPV is a newly developed fresh air intake for pig and poultry housing. The vent flap is designed so that the air is always led lengthwise along the ceiling. This ensures that the fresh air is mixed with minimum ventilation whilst the air speed at maximum ventilation is still so high that the livestock is cooled.
EUR Skov Air Cleaner is a chemical spiral cleaner for the cleaning of ventilation air from pig and poultry houses. The air cleaner is designed as a unit which is built into the air suction flue in both new and existing ventilation systems. The air cleaner consists of a spiral-shaped nozzle rod with nozzles that spray the exhaust air with an acidic fluid. The acidic fluid binds the ammonia in the air. Beneath the spiral nozzle rod there is a spiral-shaped gutter system for collection of the fluid. For each air cleaner there is a mixer tank in which the fluid is recycled. The storage tank for acid and additives is centrally located whilst dosage of the acid and additives plus drainage of the fertilizer product from the mixer tank is de-centrally regulated. Control of the air cleaner is set at the relevant requirement for cleaning the actual amount of exhaust air. Via the controls, continuous data is collated regarding how much ammonia is collected by the air cleaners.

Turbovent Agro
Duplex Gardin is a curtain system for the regulation of natural ventilation in livestock housing. The curtain can be rolled from the top downwards and from the bottom upwards. The guide rods on the curtains can be removed so that there is a wide access to the housing unit if required.
This pulsation fan is an intake and exhaust unit for mechanically ventilated livestock housing. The fan is equipped with a radial shutter which is regulated with a Linak motor. When there is an intake of fresh air, the radial shutter is angled so that the air is mixed equally and evenly distributed throughout the housing unit. At the exhaust stage, the rotation direction of the fan is reversed and the radial shutter is fully opened so that air resistance is reduced to a minimum.
FarmMaster is new and improved software for FarmMaster/Center controls for climate regulation. The control unit can be set in four new modes: Prewashing, washing, empty housing unit and heating. In each mode, heat addition, ventilation, alarms, etc. are set. The controls can also regulate temperature in two zones within the housing unit so that the livestock's requirements in the resting area and in the activity area can be individually regulated.

VengSystem
VengSystem is applied for the continuous measurement of ammonia emission from livestock housing. The system consists of a centrally placed control computer and an ammonia sensor. Ventilation air is pumped from each air exhaust via hoses to the ammonia sensor which continuously measures the concentration of ammonia in the ventilation air. A sensor is also installed in the air exhaust for the measurement of the actual air volume in the flue. By comparing the ammonia concentration with the actual air volume, the ammonia emission is calculated and stored in the memory of the computer. Ammonia data can later be applied as documentation for the relevant authorities.
EUR The newly developed climate control system from VengSystem controls and documents that the climate in the transport vehicle is as it should be. At a number of central points, the content of CO2 in the air is measured and above each pen infrared temperature readers are fitted which measure the surface temperatures of the livestock. Finally, the fan revolutions are registered plus the continuous water consumption. Independent of the control, there is alarm equipment which reacts if an error occurs. All relevant information is clearly indicated on a screen in the driving cabin. All the gathered data is also collated on a PC.

VengSystem
VengSystem, types VE122 and VE 122T are further developments of former versions of heating lamp controls. Both types of control are available without infrared temperature sensors which reducs the price by 40%. The heat is reduced on a daily basis in accordance with a graph which is integrated in the control and the heat is switched off at a particular livestock age. The VE122T also measures the temperature in the actual pen. When the temperature is so high that the piglets leave the den, the heating is automatically reduced or the heating lamp is automatically switched off. Prior to an anticipated farrowing, the controls can be set to pre-heat the piglet den at a lower heat. This ensures power savings.
