Do piglets need light?
Experimental tests have shown that piglets are not attracted to light. On the contrary, they prefer to rest in the dark! For this reason it is recommended to switch off the lamps in the creep area at night or, even better, to use heat sources with no light emissions(*).

What is the best temperature for piglets in the first few hours of life?
During gestation, fetuses live at a uterine temperature of 38 to 40 °C. The critical temperature required for newborn piglets to maintain an adequate body temperature is 34 °C(*). It has also been verified that one-day-old piglets appreciate temperatures well above their thermoneutral temperature: giving them the choice between 26 °C, 34 °C o 42 °C, piglets showed a clear preference for the highest temperature, i.e. 8 °C higher than their thermoneutral zone(**).

Why is heating by means of REAL FIRs emitted by OMEOTERM® panels more effective than traditional methods with heating lamps or heating mats?
At birth, piglets have a water content of 80% or more(*). It is also important to note that water molecules and protein in living bodies have an oscillation equal to the FIR frequency. When FIRs penetrates the deeper layers of the skin, cell vibration increases, bringing it to an optimal level and creating internal heat that is evenly distributed through the circulation and microcirculation of body fluids(**). OMEOTERM® technology, through REAL FIRs, is able to heat the living bodies in depth of up to 3 cm: this action is able to favour the mobilisation of glycogen stored in the muscles, thus promoting thermogenesis. Compared to traditional heating methods, the heat produced is much more uniform, comfortable and enveloping.

Do piglets heated by OMEOTERM® REAL FIRs dry out sooner?
Newborn piglets are covered with approximately 23 g of amniotic fluid per kg of live weight and about 50% of these fluids evaporate during the first 5-30 minutes after birth(*). Basically, unless they are provided with an extra heat source, the heat-producing capacity of piglets during the first half hour of life barely covers the amount of energy required for the evaporation of 50% of the fetal fluids. For this reason, piglets experience a sharp drop in temperature during the first few post-natal hours and it is estimated that they can lose more than 2 °C of body temperature between birth and the first ingestion of colostrum(**) partly due to the high surface-area-to-volume ratio attributable to their size(***). The molecules of the liquids that make up the amniotic fluid are aggregated into clusters. In order to evaporate the moisture from the amniotic fluid more quickly, it is necessary to disaggregate the clusters into smaller ones (declustering). FIRs effectively perform the declustering action, which allows, due to a larger heat exchange surface, more efficient evaporation. This decreases the amount of body heat used by the piglets to evaporate the amniotic fluid, thus avoiding hypothermia and increasing the chances of survival of the litter. Drying piglets (especially low weight piglets) has been shown to reduce the drop in body temperature to which they are subjected immediately after birth (****).

Can heating through OMEOTERM® REAL FIRs have beneficial effects on health?
The increased availability of water declustered by FIRs promotes homeostatic balance, cellular hydration processes and exchange of substances between blood and tissues. Several studies claim that FIRs strengthen the immune system and improve the blood circulation process of the skin, muscles and connective tissues by providing more oxygen and nutrients. FIR radiation elements are used to warm newborn babies in incubators in paediatric wards and are also widely used in other medical and therapeutic areas(*).

Do OMEOTERM® REAL FIRs heat faster than conventional systems?
In radiant heating, heat transmission is almost instantaneous, as FIRs diffuse at the speed of light. At a rom temperature of about 20 °C, OMEOTERM® heating panels take about 90 seconds to reach their operating temperature, with a remarkable thermal reactivity. In fact, FIRs have the prerogative of not heating the air. This allows a considerable saving of energy and time, because there is no loss of energy efficiency dissipated in the double passage between heating element and air and between heated air and objects and/or living organisms, as it happens in traditional heating. The thermal reactivity of the OMEOTERM® REAL FIRs allows the application of the BIOTEMP SYSTEM technology.

7.
Are FIRs harmful?
OMEOTERM® technology uses only REAL FIR or IR–C (type C Infrared Rays), which represent only a portion of the solar electromagnetic spectrum. They are the good part of the sun’s infrared radiation and are not harmful at all, even after prolonged exposure. On the contrary, prolonged exposure to IR-A (Short Wave Infrared Rays) or IR-B (Medium Wave Infrared Rays) can cause harmful effects on the eyes and skin.
8.
Do FIRs emit light?
FIRs represent that portion of the solar electromagnetic spectrum that is farthest from visible light: they do not therefore emit light, but we can experience them sensorially in the form of heat. FIRs emit only thermal radiation, have a wavelength of 4 μm-1000 μm and can transfer energy in the form of heat. In contrast, conventional so-called “infrared” lamps are normal filaments lamps, which emit heat via the visible light spectrum emitted by an incandescent filament and by heating the filament itself. These two thermal components pass through a red coloured glass bulb with a very small proportion of infrared rays, most of which are IR-A (Short Wave Infrared Rays) inside the visible light spectrum, which are known to have very low thermal efficiency and are harmful to retinal tissue.

What is the expected lifetime of an OMEOTERM® panel?
OMEOTERM® panels comply with the legal guarantee of 2 years, but their lifespan is much longer: if they are installed properly and used correctly, they can certainly achieve several years of perfect operation, well beyond the end of the guarantee period! The OMEOTERM® panel is certainly has no fear of comparison either with the maximum duration of the lamps, declared by the main manufacturers to be max 5000 h, or with traditional lamp holders (subject to frequent deterioration caused by the high temperatures reached), nor with that of electric mats, which ascertained field situations confirm having frequent problems of power cuts due to breakage of the heating element. The OMEOTERM® panel has been designed and manufactured with construction and quality criteria for continuous use without malfunctions, deterioration and/or programmed obsolescence even in the very long term.
10.
What temperature does the OMEOTERM® panel reach?
The OMEOTERM® panel is made up of two sides: the heat emission side can uniformly reach 90 °C, well below the 180 °C found on the bulb of the filament lamps. The panel achieves an optimal surface temperature on the front side (the radiant wall) without energy loss on the back side. The non-heating side is insulated with a high performance reflective multilayer insulation made of aluminium and Trocellen, in order to properly redirect the FIRs to the emitting side. This is very important because it reduces the risk of overheating the sow and saves energy.

How is it possible that the OMEOTERM® panel, which reaches a temperature of just over 90 °C, heats up more than a lamp that reaches 180 °C?
The temperature of filament lamps, measured with an IR camera, reaches approximately 180 °C (measured on the surface of the bulb), but the output on the ground, on a mat placed on the grid at a distance of about 50-60 cm from the heat source and with a room temperature of about 20 °C, is only 20-22 °C. The OMEOTERM® panel only reaches 90 °C, but, thanks to its efficient thermal technology by REAL FIR radiation, the yield on the ground, at the same room temperature, easily reaches and exceeds 30 °C, with a significantly higher heat footprint area.
12.
What is the difference between heating by convection, conduction and by and radiation?
Heat spreads by conduction when it is transmitted from one solid body to another, placed at different temperatures and in contact with each other (e.g. heating mats).
Heat spreads by convection when it is propagated in fluids such as water, but also gases such as air (e.g. traditional filament lamps with coloured bulbs, Aniheater-type radiant lamps and thermal radiators).
Heat is propagated by radiation when the transmission of heat occurs through the radiation emitted by the source towards the irradiated body, without the presence of an interposed transmissive medium (air or water): it can also be achieved through the void.
OMEOTERM® REAL FIRs emit heat by radiation, i.e. they do not heat the air, producing heat only when they radiate an object, such as a wall, or a living body.

13. Is the OMEOTERM® HEATING SYSTEM ECONOMICAL?
The affordability of the OMEOTERM® panel is given by:
- very high energy efficiency guaranteed by the E–Heating technology, the innovative EEE technology that directly converts electrical energy into thermal energy, which means there is no loss of dissipated energy in the double passage between the heating element and the air, and between the air and objects and/or living organisms, as happens in traditional lamp heating;
- high directionality (it heats directly only the bodies and surfaces it radiates);
- the OMEOTERM® system does not need additional piping, boilers or electrical systems, but is installed with easy, practical and economical assembly solutions.
The simultaneous use of the OMEOTERM® panels and the BIOTEMP SYSTEM also provides a further economic benefit, as operation is controlled and managed by an electronic control unit that can be programmed as desired, according to the needs and temperatures required by the piglets in relation to their state of growth. In practice, the BIOTEMP SYSTEM makes it possible to use the panels by optimising their Duty Cycle, allowing energy savings of 30 to 50%.
14.
Do OMEOTERM® panels require maintenance?
ZERO MAINTENANCE! OMEOTERM® panels do not require any routine maintenance and there is no loss of efficiency over time, as is the case with filaments lamps. The mere presence of dirt on the surface of the glass bulbs can reduce the heating capacity of lamps by up to 5 °C.

Are OMEOTERM® panels easy to clean?
Absolutely yes, the smooth surfaces without recesses allow and encourage easy cleaning.
16.
Does the OMEOTERM® panel allow easier access to the farrowing pen?
Yes, the OMEOTERM® system has easy access features, because the panels can be easily supported thanks to the specific Panel Kit (optional), made up of hinged frames that allow them to be tilted vertically at 90°, making access and operation inside the farrowing pen much easier.

Are OMEOTERM® panels waterproof?
OMEOTERM® panels are splash-water resistant, i.e. resistant to indirect medium volume water splashes. Their structure is composed of a double insulated radiant membrane, embedded in a multi-cell polycarbonate compound panel. The edges are made of polycarbonate profiles adhered to the panel, whose support angles are screwed. The junction box from which the power cable departs is solidly fixed to the polycarbonate panel and the contact edge between the box and the panel is covered by a gasket, which, like the cable gland, is also fitted with a seal. All this allows us to assert that the water resistance of the OMEOTERM® panels is not inferior to that of the reflectors with Edison lamp holder that are commonly used.
