Frequently Asked Questions
Laser welding provides extreme precision, creating nearly invisible joints that are significantly stronger and more leak-resistant than traditional welding, while offering a superior aesthetic for modern interiors.
No, these radiators are specifically designed for hot water heating systems. The use of steam or geothermal water systems is strictly prohibited to ensure safety and longevity.
For optimal performance, ensure the system is closed with a pH value of 9–12, chloride ≤ 300 mg/L, and sulfate ≤ 150 mg/L, and keep the system filled with water during non-heating periods.
Under normal operating conditions and proper water quality maintenance, these radiators are engineered to last up to 15 years.
We offer four modes: same-side top inlet/bottom outlet, opposite-side top inlet/bottom outlet, opposite-side bottom inlet/bottom outlet, and 90° vertical bottom inlet/outlet.
Their streamlined round-column shape, lack of visible weld seams, and available matte finishes allow them to blend seamlessly into clean, architectural spaces without creating visual clutter.
