3 INTRODUCTION SABIANA is the leading company in Europe in the design, production and sale of radiant panels operating on hot water, high temperature hot water and steam. Since 1971, over 5 million square metres of panels installed in different environments (small, medium and large industries, hangars, gyms and theatres, small and large offices) prove the quality of the SABIANA radiant heating system and products. Heat by radiation means absolute silence, no movement of air and a uniform temperature in the entire environment. In effect, being distributed better, the heat is more pleasant and comfort is optimised, without increasing the air temperature. The result is a feeling of absolute comfort with an air temperature that is 3 C lower than the operative temperature perceived by people. The efficiency of the SABIANA radiant panels is also economic. In fact, besides the energy savings due to the fact that the operative temperature is different from the air temperature, this totally static product does not, unlike the traditional systems, have an electric motor and does not require maintenance nor the consumption of electricity. This translates into longlasting efficiency. The SABIANA radiant panels have a practically unlimited duration. The SABIANA radiant panels can be described as the hygienic heating system par excellence. The system does not create noise nor movement of air and therefore dust. In addition, it avoids annoying streams of air and the circulation of germs, dust and fragrances and thus represents an important contribution to the prevention of allergies and illnesses.

4 MAIN ADVANTAGES OF THE PULSAR Thermal performance The PULSAR radiant panel is totally static (no circulation of air and no movement of dust). Very low thermal gradient between the floor and the ceiling. Extremely fast response to changes in settings, without thermal inertia. The operating principle of the PULSAR radiant panels is reversible, and thus cooling operation is possible using the radiant ceiling panels, by connection to a chiller or heat pump. Appearance None of the peripheral walls are affected by the installation. The PULSAR radiant panel can be perfectly integrated into all types of false ceiling. The visible side is perfectly smooth, adapting to any type of architecture. Other RAL colours available on request. Modularity Given its modular dimensions and the design of the water connections, the PULSAR panels can be installed in sequence with ceiling light panels, in complete compliance with the regulations on artificial lighting. Hygiene The design of the PULSAR panel allows it to be installed in any building, including hospitals and clinics. Indeed, its completely smooth visible surface is recommended, as it allows sanitisation by spraying for combating nosocomial illnesses in hospitals. The radiation concept, by avoiding considerable movements of air, prevents the spreading of microbes and bacteriological pollution. Safety The PULSAR radiant panels are inaccessible to the people in the room. Therefore there is no risk of burning or electric shock in schools and paramedical environments. No risk of vandalism, in any environment. Comfort By design, the PULSAR radiant panel guarantees a uniform temperature in all seasons. The PULSAR radiant panel is a totally static heating system without the circulation of air and without lifting dust. The operation of the PULSAR is completely silent. In summer, the PULSAR panel can be used for cooling without creating steams of air and with a uniform temperature throughout the environment. Savings The heating requirement of a building heated with the PULSAR radiant panels is, according to the EN 1831 standard, much lower than the requirement with traditional heating systems. The experience acquired by SABIANA in the field of radiant panels guarantees the reliability of the PULSAR over time. The PULSAR does not require special maintenance and consequently has no maintenance costs. Assembly The dimensions of the PULSAR radiant panels make them easy to handle on site. The panels are connected by flexible pipes without welding. Connections supplied not mounted

5 TECHNICAL SPECIFICATIONS Technical description The SABIANA PULSAR radiant panels are supplied in four sizes, which can be perfectly integrated into any false ceiling. Indeed, the lengths of 1.0, 1.80,.40 and 3.00 m ensure optimum integration into 600 x 600 mm modular ceilings, the standard dimension for false ceiling panels in Europe. The visible side is perfectly flat, meaning that the PULSAR radiant panels can match all types of false ceiling panels available on the market. As standard, the panels are supplied in the colour RAL 9010, with a satin finish created by an epoxypolyester coat dried in a furnace at 180 C. Other RAL colours are also available for the architect to choose from. The PULSAR radiant panels are made of a radiating galvanized steel plate, 1 mm thick. On the panel is fixed a copper pipe, 0.75 mm thick and with mm of external diameter. The pipe is oblongshaped in order to optimize the contact surface with the radiant panel. The galvanized hanging strips welded to the panels hold the correct spacing of the tubes and secure the best surface contact between the tube and the panel. The paint complies with the European Standard 76/769/EEC. Class of reaction to fire: A1 Emission of the radiant surface: Є = 0,96 The PULSAR is supplied with an insulating layer of mineral wool (30 mm thick) protected by an aluminium sheet (5 micron thick) to be mounted on the top of the panel.
