Copper-aluminum radiator RD3/140 bottom connection REGULLUS RD0314

Efficient copper-aluminum radiator for modern heating systems

The REGULUS RD3/140 radiator with a bottom connection combines efficiency and modern technology. The construction based on copper heating tubes and aluminum fins ensures quick heating and effective heat distribution in the room. This makes it ideal for both traditional and energy-saving central heating installations, including those powered by condensing boilers or heat pumps.

The radiator is characterized by a mixed mode of heat emission – radiation and convection – which translates into thermal comfort and optimal energy use. Low water capacity and thermal inertia allow for quick response to temperature changes, enabling precise heating control and savings.

Construction and benefits of use

The core of the radiator consists of copper heating tubes connected to collective manifolds. Aluminum fins, mounted on the tubes, increase the heat exchange surface, and their special profile ensures even temperature distribution. The connection of copper and aluminum is made using a dry method, eliminating the risk of electrochemical corrosion.

• High efficiency: thanks to the use of copper and aluminum and a special fin design, the radiator provides high heating power with a relatively low supply temperature.
• Fast heating: low water capacity means the radiator quickly reaches the set temperature, which translates into user comfort and energy savings.
• Durability and reliability: the dry connection of copper and aluminum guarantees long-term operation without the risk of corrosion.
• Versatility: the possibility of a bottom GW 1/2 inch connection facilitates installation in various installations.
• Completeness: the set includes essential mounting accessories – manual air vent, thermostatic valve with pre-setting and mounting elements.

The REGULUS RD3/140 radiator has dimensions of 305 mm height, 1400 mm length and 90 mm depth. Its heating power at a temperature of 20°C / 75/65°C is 1287 W. The maximum working pressure is 1.5 bar, and the maximum supply temperature is 110°C. The water content in the radiator is 0.63 liters. It is made of high-quality materials and coated with powder paint in white (RAL 9003), which ensures an aesthetic appearance and corrosion resistance. It is equipped with a valve plug and side covers for increased safety. The connection spacing is 50 mm.
