FRESH AIR INLETS FOR INSTALLATION INTO THE CEILING Ceiling inlets are well suited for noncentralised fresh air supply in houses with a ceiling below the roof space. The objective is to create optimal air circulation inside the building at all times, delivering a consistent internal environment that meets the pigs’ When outside temperatures are low, the fresh air flows along the ceiling, where it warms up before it enters the animal area. requirements and does not fluctuate when external temperatures rise or fall. When outside temperatures are high, the inlet flap is fully opened and the...

One of the main characteristics of the CL 1540 inlet is the inlet flap, which is shaped like a large shovel. This unique feature ensures that even when the inlet flap is wide open, the air flows along the ceiling, where it mixes with the warm house air. For regions that are very warm and humid, the flap can be opened even further than the standard 100 per cent position (i.e. parallel to the floor). The air can then flow vertically into the animal area, at a high speed, creating the windchill the pigs need to cool down. CL 1540: wide open inlet flap in the summer In houses with a sloped...

DIFFUSED FRESH AIR THROUGH THE CEILING Fresh air is supplied uniformly along the entire ceiling for an even air distribution at a very low air speed. The slow and even distribution of the fresh air is an advantage especially in the winter and in nurseries because draughts are prevented. DiffAir ceiling Fresh air provided through the entire ceiling The DiffAir ceiling serves both as a diffused fresh air supply system and economical ceiling insulation. It consists of glass-reinforced plastic (GRP) trapezoidal or aluminium sheets. Aluminium sheets have the advantage of being incombustible....

FRESH AIR CHIMNEY FOR NEGATIVE AND BALANCED PRESSURE VENTILATION Fresh air chimneys draw fresh air from the roof and distribute it evenly throughout the house. They are particularly useful when: 4 fresh air distribution along the side walls or the ceiling is not possible due to building design, or not requested; 4 the building is extremely wide and low and cannot achieve good air circulation from wall inlets alone; 4 a balanced or negative pressure system is to be used, e.g. due to leakage of the building. F.A.C. 2 (Fresh Air Chimney) Fresh air supply from the roof F.A.C. 2 consists of a...

LARGE AIR INLETS FOR TUNNEL VENTILATION Using a tunnel, CrossTunnel or CombiTunnel ventilation system requires large air inlets. Depending on the selected system, these inlets are installed either near the gable ends at each side of the house, directly in the gable, or along one long side of the house. The inlets allow the fresh air to enter the house over a large surface, displacing the stale air without mixing with it. Constant and high air speeds at animal level reduce the temperature perceived by the pigs (windchill factor). Tunnel ventilation with MultiVent 17 M and RainMaker...

CURTAIN SYSTEMS FOR NATURAL VENTILATION Natural ventilation in pig housing is a good option especially in regions without frost – and is available at a reasonable price. Investment costs for natural ventilation systems are low, and they consume little energy. The air exchange depends on wind direction and wind speed. To control the air exchange, curtains with electric winches are installed along both long sides of the building. The independent control of the curtains on each side is either based on temperature only or additionally supported by a weather station. Natural ventilation in...

Houses with open-air runs and open houses are ideal for keeping pigs in conditions that are as similar as possible to their natural environment, and to offer them different functional and climate areas. Natural venti lation is the preferred ventilation system for such houses. To protect the pigs from bad weather (storm, rain, cold), roller curtains are a good closing system. The natural movement of the air, in combination with the thermal flow, ensures that sufficient fresh air flows through the house. In addition to curtain control based on the temperature, Big Dutchman also recommends...
