Ideal house temperatures have a substantial influence on pig health and performance. Adequate heating systems are therefore required in many climate zones. The overall goal is to maximise the thermal yield and transfer it to the pigs in the best possible way to keep energy costs as low as possible.
Big Dutchman offers several different systems for full-space or zone heating powered by gas, oil or hot water.
JetMaster is available for operation with natural gas or propane. It is controlled by means of a thermostat and equipped with a flame guard. If, for some reason, the heater does not ignite or the flame is extinguished, the gas supply is immediately shut down so that no unburnt gas escapes. The built-in fan provides a wide throwing range and distributes the warm air ideally.
The Burner Control Unit (BCU) makes it possible to balance uneven temperatures inside the house using the JetMaster‘s air circulation mode by switching it to »ventilate only«. A connection to a chimney is not required. The heat generated is 100 % beneficial to the animals. Depending on the house size and type of equipment, different models are available.
RGA heating devices are operated by a closed combustion process. This means that the house air remains free of flue gases as these are guided towards the outside via a chimney. In addition, fire danger is minimised significantly. The built-in fan provides a wide throwing range and distributes the warm air ideally in the house.
Delta pipe and Twin pipe
Delta and Twin pipes are especially well-suited for ceilings with spray-cooling channels and DiffAir ceilings. They are made of aluminium and are operated with hot water, of which they require only a limited amount, however. Thanks to their good thermal conductivity (heat output of 180-200 watts/m) they ensure constant room temperatures inside the house.
These heating systems can also be used as pre-heating in the central aisle. The pipes have an anodic coating for a better protection against ammonia. They are of comparatively low weight and can be delivered in different sizes up to a length of 6 m. The pipes are easy to assemble.
The fin heater consists of a galvanized tube or of an aluminium tube with epoxy powder coating through which hot water is pumped. Fins are welded to the tube like a spiral, creating a large surface of 1 m2/running metre of tube. Heat emerges from these fins and causes a strong thermal. The heat output can be as high as 600 watts/running metre.
The spacing between the fins is large enough to ensure that dust does not accumulate. The tubes are fastened to the wall by means of angle brackets or suspended from the ceiling, which is very easy to carry out. An automatic ventilation (for Delta and Twin pipes as well) ensures a high functional reliability of the heating system.
HeatMaster and Heat-X® compact
Both HeatMaster and Heat-X work on a hot-water basis. A gas, fuel oil or wood chip system or the waste heat produced by a biogas plant or CHP can be used to heat the water.
The main components of both air-to-water heat exchangers are a fan and a system of fins made of stainless steel, which are easy to clean by means of a high-pressure cleaner, and corrosion-free.
HeatMaster is either suspended along the sides at the height of the fresh air inlets or mounted to the wall. In case of the sucking version, the fan sucks the air through the exchanger element. The throwing ranges achieved in this manner are very wide.
Heat-X® compact is an extremely handy heater blower based on a heat exchanger. Thanks to its compact construction, the blower can easily be installed in small compartments or service rooms to warm the air. Practical plug-in couplings including dust protection increase flexibility if the heater is to be used in different locations.
Piglets need a lot of warmth, especially during the first days after moving to the rearing house so as to be able to cope better with the critical weaning period. Ideally, the resting area should have a temperature of approximately 32°C. Apart from traditional full-space heating, zone heating operated with hot water is becoming increasingly popular for pig rearing houses.
Such zones are created using a covering plate or »hover« that is fixed at a distance of 70 to 80 cm above the slatted floor. The required dimensions of the cover depend on the number of piglets and the depth of the pen. An edge of approx. 20 cm in the front area of the plate helps to create a heat blanket. The heating system (Twin pipe) is installed directly below the plate.
The main purpose of this system is to heat the resting area of the piglets. As the rest of the pen does not require as much heat, therefore making lower temperatures possible, heating costs are significantly reduced.
