The Objective of VentilationGreat demands are made on the climate system in the livestock house to ensure an exact adjustment of temperature, air humidity and air velocity in order to create optimum conditions. Animals of highly improved breeds combined with a high stocking density require a climate of pre-cise adjustment.

If the air humidity rises, the animals sense a higher temperature even though the temperature is actually unchanged. Like-wise, a low humidity can make the animals feel a lower temperature even though it has not been lowered.

The opposite applies as regards air velocity. If it is increased, the animals feel a lower temperature even though the temperature is unchanged.

There is only one correct temperature – if it is not sustained an optimal productivity cannot be maintained.

Combi-Tunnel VentilationThe system can be used in the subtropi-cal/temperate regions of the world. Com-bi-Tunnel ventilation has been designed for areas where there is a major difference in temperature with warm summers and cold/cool winters and/or great difference between the day and night temperatures.

At low outside temperatures, the system ventilates according to the side mode principle with air intake through wall inlets and air outlet through chimneys in the roof or wall fans.At high outside temperatures, the system ventilates according to the tunnel prin-ciple. The air is taken in through cooling pads and the air outlet is conducted through large gable fans at the opposite end of the house. A cool airflow is created lengthwise in the house. It is often pos-sible to create a cooling effect of 10-25°C.A Combi-Tunnel system is 100% flex-ible and can be adjusted to any kind of production, and by and large all livestock

houses. The system also provides a stable climate in the house all the year round.

A Combi-Tunnel System consists of:

Air intake:• In side mode, the fresh air is supplied through DA 1211/1911 wall inlets. In tunnel mode, the fresh air is supplied at one end through side open-ings controlled by Rack & Pinion – the openings are made with cooling pads.Air outlet: • In side mode, air is exhaust-ed through DA 600/920 exhaust units in combination with wall fans. In tunnel mode, air is exhausted through gable fans.Climate control: • DOL 534/539 ensures efficient and accurate climate control.Interlinking:• – DA 75 winch motor, pull rod, wires and other sturdy mechanical parts.

The system can be supplemented by alarm and emergency opening, high-pressure cooling and FarmOnline®.

The Structure of a Combi-Tunnel System

Fresh air is taken in through wall inlets during cold periods, thus creating minimum ventilation to remove the excess moisture and heat of the animals; furthermore, the air velocity is kept at a low level. During hot periods, fresh air is supplied through a tunnel opening to create a cooling air current in the longitudinal direction of the house. Air is let out through wall fans/chimneys dur-ing cold periods and through gable fans during hot periods.

Air IntakeAt low outside temperature, the air inlet is conducted through wall inlets. At high outside temperature, the air inlet is conducted through tunnel openings with cooling pads at one end of the house. Rack & Pinion handles the opening/clos-ing of these openings.

DA 1200/1211/1911 Wall InletDA 1200/1211/1911 is a series of wall inlets for building into concrete walls or fixing to the inside of light-weight walls.

DA 1200/1211/1911 CharacteristicsAn air direction plate directs the air jet in •an optimum direction along the ceilingA shutter reinforced by a metal band •ensures that the inlet shuts tightlyInsulated shutter counteracts condensa-•tionQuick and easy to clean with a high-•pressure cleanerAvailable with a light trap and fine mesh•

Possible to mount a light trap on DA •1211.

Cooling Pads and Gutter SystemPad cooling is used for cooling of large air quantities. Fresh air is directed through cooling pads sprinkled with water and thus creating a cooling airflow through the house.Cooling pads are mounted in a flexible gutter system, where the water reservoir is integrated in the lower gutter.

Cooling Pads and Gutter System - Characteristics

Recirculate large quantities of water and •thus a high cooling effect is obtainedPads of a recognized make with long •lifetimeThe separation function removes salt •from the recirculated water and obviates accumulation of salt.

Water reservoir integrated in the gutter •system – no need for separate water tankClick system for quick mounting and •dismounting of pads.

Rack & PinionThe Rack & Pinion closing system is a com-plete solution where SKOV supplies critical components.

Rack & Pinion CharacteristicsThe air inlet can be built up by one or •several panelsThe powerful motor is mounted directly •on the pipes and works without wire or other mechanical parts.

Tunnel Door Light is an alternative to Rack & Pinion. An extremely flexible light-weight system which can be adapted to most door materials.

Air OutletAt low outside temperature, the air outlet is conducted through DA 600/DA 920 exhaust units or wall fans. At high outside temperature, the air outlet is conducted through big gable fans.

DA 600/DA 920 Exhaust UnitDA 600/920 is designed in such a way that the fan inside the chimney offers the highest possible air performance at the lowest possible power consumption. This is achieved without diminishing the pres-sure stability of the chimney. The DA 600/920 exhaust unit can be adapted to the individual building as regards roof pitch, colour, side/ridge instal-lation, attic, etc.

InterlinkingA mounting kit is supplied together with the various components, subsystems and systems containing all necessary parts in the form of washers, wires, screws, fittings, pulleys, etc. It is important that all pieces in the ventila-tion system are linked correctly in order to

ensure optimal utilisation of the system.DA 75 Winch MotorDA 75A is a series of very sturdy and com-pact winch motors, specially designed for inlet controls and tunnel doors in ventila-tion systems.

DA 75 CharacteristicsCan pull open up to 128 wall inlets•Open/close switches for manual control•24 V version can be used for emergency •openingMechanical override of emergency •opening.

Alarm SystemDOL 2200 is a flexible and reliable fail-safe alarm system, which can be adjusted to the current production quickly and easily.

DOL 2200 CharacteristicsAlarms through a local alarm or tele-•phoneWith built-in module for fixed-line or •GSMCan monitor the temperature in ten •sectionsExtension module - ten extra alarm •inputsOutline through graphic display•Voice computer - Voice alarm - voice •messageCompensation for high outside tem-•perature.

Emergency OpeningIn modern production facilities where the stocking density is high, an alarm call is insufficient when it concerns ventilation malfunction - simply because ventilation malfunction requires immediate action.

DOL 278 Emergency Opening System – ON/OFFTogether with SKOV’s climate computer, DOL 278 is an independent emergency opening system for opening the ventila-tion system completely in case of power or technical failure. The actual emergency opening function is integrated into the climate computer, only the energy for opening the ventilation system is drawn from DOL 278. In case of a power failure, the connected air inlets and outlets are forced open and the emergency opening system opens completely.

High-Pressure CoolingInstallation of high-pressure cooling can delay and equalize the transition from side mode to tunnel mode. With a high-pres-sure cooling system you get more than just cooling.

DA 2000 high-pressure coolingWith high-pressure cooling, the air is pro-vided with finely atomised water vapour. It cools the air in the house during the evaporation process. With correct high-pressure cooling, it is possible to reduce the temperature in the house by 2-10°C. The nozzle is fixed in the patented noz-zle clip FlexClamp and so it can easily be mounted on and removed from the piping.

A high-pressure system can also be used for both humidification and dust binding.

Between the batches, the high-pressure system can be used for soaking and disin-fection of the livestock house.
