Copper-aluminum radiator R4/40 side connection REGULLUS RB0404

Copper-aluminum radiators – efficient heating for the future

Copper-aluminum radiators REGULUS combine modern technology and a proven design, ideal for various heating systems. Model R4/40, with a side connection, is distinguished by its high efficiency in both traditional and low-temperature installations. The construction based on copper heating tubes and aluminum fins ensures rapid heating and even heat distribution in the room. This solution is particularly appreciated by installers due to its ease of installation and integration with existing systems.

REGULUS radiators utilize a mixed mode of heat emission – radiation and convection – which translates into thermal comfort and energy savings. Low water capacity and low thermal inertia mean that the radiator quickly reaches full power, allowing for precise temperature control. This is particularly important in installations powered by heat pumps or condensing boilers, where efficiency at low heating medium temperatures is key.

Construction and benefits of use

The REGULUS R4/40 radiator consists of two main elements: a water system based on copper tubes and manifolds, and a heat dissipation system with aluminum fins. The combination of these materials ensures high thermal conductivity and corrosion resistance. Copper tubes are hard-soldered, guaranteeing the durability of the connections. The appropriately shaped aluminum fins increase the heat exchange surface area, and their construction ensures an even temperature distribution.

• High efficiency: thanks to the use of copper and aluminum, the radiator heats up quickly and efficiently releases heat.
• Low water capacity: quick reaction to changes in supply temperature allows for precise heating control and energy savings.
• Versatility: can be used in various heating systems – from traditional boilers to heat pumps and low-temperature installations.
• Durability: the combination of copper and aluminum is dry, eliminating the risk of electrochemical corrosion.
• Aesthetic appearance: profiled fins and white finish (RAL 9003) provide an aesthetic appearance of the radiator that fits into various interiors.
• Complete equipment: the set includes a manual air vent, wall brackets and a set of gaskets and mounting screws – everything needed for proper installation.

Technical specifications and operating parameters

The REGULUS R4/40 radiator is characterized by dimensions of 395 mm height, 400 mm length and 90 mm depth. Its water capacity is 0.33 liters, and the maximum working pressure is 1.5 bar. The heating power at a supply temperature of 75/65/20°C is 341 W. The radiator has a 1/2 inch internal thread and is adapted for a side connection GW 1/2". Thanks to the symmetrical construction, it can be mounted on either the left or right side to the wall - this facilitates installation in tight spaces or with limited access to connections. Additionally, the radiator is available in a wide range of RAL K7 colors (at no extra charge) and in metallic and structural versions (at an extra charge).
