4. Watercool Heatkiller RAD, 280 mm, S - stainless steel
We have expanded our range of high-quality radiators of the HEATKILLER RAD series with 280 and 420mm versions. We rely on the highly popular slim format (S) with a height of 30mm. In addition to the increased performance, the radiators are characterized by their compact dimensions and the characteristic high-quality Watercool workmanship.
Finishing and quality control in Germany
In cooperation with a well-known manufacturer from Asia, we have succeeded in creating a high-performance mesh radiator with a unique look. The cooling cores are manufactured strictly in accordance with our specifications. The radiator housing is produced directly on our premises in Waren, which means that the assembly and quality control are ultimately performed in Germany.
High cooling performance over the entire speed range
The goal of the development was to produce competitive radiators with a wide performance range. Accordingly, the HEATKILLER RAD provides a very good cooling performance with slow rotating fans, which scales very well with increasing speed. For maximum cooling performance, the HEATKILLER RAD can of course also be used in push/pull mode.
The best raw materials in use
Only high-quality raw materials are used as the basis for the HEATKILLER RAD. The pre-chamber and the cooling channels are made of brass, and the cooling fins are made of copper. The side panels are laser-cut from 1mm thick steel plates or stainless steel and subsequently brushed or powder-coated in black or white, depending on the finish. The front sides are made of brushed stainless steel and significantly contribute to the exclusive look of our HEATKILLER RAD.
Easy integration into the cooling circuit
The integration into the cooling circuit is done with two standard G1/4 inch threads. The required connections are not included in the scope of delivery. The small width of only 120mm ensures a maximum of flexibility.
