b!klimax radiant wall/ceiling system

We have been working in an ideal climate for thirty years. A climate that has brought us to a position of leadership in Italy in the field of radiant heating and cooling. RDZ was the first company to receive the management system quality certification (today UNI EN ISO 9001:2008). RDZ has been a quality-oriented company since its very beginning, using the finest materials, developing new solutions, constantly providing excellent service. And also by creating a positive climate in the company to promote the exchange of ideas and stimulate cooperation for constant improvement.

b!klimax radiant heating system for wall or ceiling installation. Built to fit your wellbeing. b!klimax is an integrated radiant heating and cooling system that can be installed on walls or ceilings. Developed by RDZ through continuous technological research on heating and cooling for all seasons, b!klimax is simple, functional and... revolutionary. b!klimax is an innovative system that exploits the ability of large surfaces (ceilings and walls) to exchange heat with the environment by radiation. Thanks to b!klimax the human body can perfectly balance its heat exchanges, increasing the level of perceived comfort. 1

2 Wall and ceiling heating and cooling

Invisible comfort in every season. Innovative and versatile, b!klimax is a radiant heating and cooling system for wall or ceiling installation. It is the ideal solution in rooms where it is important to maintain comfortable conditions all year round. Its very low thermal inertia and high efficiency make b!klimax the ideal system for houses, renovated buildings and commercial applications. Completely concealed in ceilings or walls, b!klimax makes it possible to use all the available space while improving the appearance of the room. 3

Wall and ceiling heating and cooling Comfort without draughts. With b!klimax there will be no more of those cold draughts caused by traditional air conditioning systems. 4

The Reasons for Choosing b!klimax. b!klimax means comfort. The uniform distribution of heat and cold emitted by the walls and the ceiling through radiation guarantees a homogeneous temperature inside the room, without annoying cold air draughts. b!klimax is a low-temperature system that saves you money on operating costs and can be used with eco-friendly, alternative energy sources. The absence of any convective movements caused by temperature differences between the heating body and the environment means that no dust or impurities are blown into the air, thus improving hygiene. 1 2 3 4 5 6 7 Ideal for summer and winter. Lower energy consumption. High thermal output. Low thermal inertia. Greater aesthetic freedom. More respect for nature. Better hygiene, better health. 5

Radiant Panels are the Heart of b!klimax. Radiant panels are light, easy to handle and simple to install. They are reliable, they prevent thermal bridges and guarantee full freedom to choose any form of wall covering or decoration. 6

b!klimax: Maxi Manifolds. Using suitable temperature control systems (and buffer tanks, if necessary), the water is sent from the heat generator (boiler or chiller) to the main manifolds (called Maxi manifolds) and from there to the radiant panels, passing through secondary manifolds called distributors. Special deaerators (air traps) are installed upstream from the Maxi manifolds to keep the system fully efficient at all times. 1 Maxi manifolds Code 6302002-010 Made of plastic material, Ø 1 1/4, modular assembly, ideal for high flow-rate, equipped with shut-off valves, which can be provided with electrothermal heads controlled by a thermostat, air vent and discharge valves, thermometers on delivery and return flow, brackets, Y filter and fittings for Ø 20 mm pipes. Anti-condensation shells are supplied as standard. 2 3 Electrothermal head Code 6301010 Electrothermal heads to control each circuit through a room thermostat. Protection degree IP 44.

b!klimax: Distributors. The distributors are an important part of the system. The Maxi manifold is connected to the distributors by pre-insulated Ø 20x2 mm polybutylene pipes, while the distributors are connected to the panels by pre-insulated Ø 6x1 mm polybutylene pipes. 1 Pair of 8-way closed distributors Code 6210050 Pair of manifolds made of plastic material, designed to facilitate the connection of b!klimax panel pipes.

Pressure loss in Ø 6x1 mm pipe Pressure loss (DaPa/m) water speed (m/s) Ø 6 mm PB pipe Code 6320006 Ø 6 mm PB pipe with antioxygen barrier conforming to DIN 4726 EN12319-2. Example: Assuming that a basic circuit (Ø 6 mm, length 15 mm) has a flow rate of 20 kg/h, the pressure loss is approximately 116 DaPa/m, and the total loss is 116 x 15 = 1740 DaPa. Flow rate (kg/h) 22

b!klimax: Hydraulic Characteristics of Ø 20x2 mm PB Pipes. Pressure loss in Ø 20x2 mm pipe Pressure loss (DaPa/m) water speed (m/s) Ø 20 mm PB pipe Code red 6300620, Code blue 6310620 Ø 20 mm PB pipe with anti-oxygen barrier conforming to DIN 4726 EN 12319-2 and insulating sheath. It is used to connect the distributors to the Maxi manifolds. Example: By connecting 20 basic circuits through the Ø 20 mm pipe using the distributors, the water flow rate is 20 kg/h x 20 circ. = 400 kg/h. The chart shows a pressure loss of 28 DaPa/m and, considering a pipe 20 m long, the result is 28 x 20 = 560 DaPa. Flow rate (kg/h) 400 23

RNW Dehumidifiers and Heat Recovery Units. Dehumidifiers to control relative humidity in radiant heating/cooling systems. Each machine is a cooling unit equipped with 2 additional heat exchangers that exploit the availability of chilled water (15-18 C) used by the radiant panels. The pre-treatment coil, located under the evaporator, reduces the temperature of the air, lessening the sensible load on the evaporating coil. The post-treatment coil, located after the condenser, reduces the temperature of the air before sending it back to the room. This treatment produces dehumidified air with the same temperature as the air inside the room. Basically, RNW dehumidifiers control the latent load ; this increases the efficiency of the cooling unit, which supplies the panels with water at higher temperatures than the temperature usually required for dehumidifying.
