Frequently Asked Questions
No, our steel three-column round radiators are specifically designed for hot water heating systems. Use in steam or geothermal systems is strictly prohibited.
The radiator is suitable for closed heating systems with a medium temperature not exceeding 120°C, typically operating at ≤ 95°C.
The three-column structure increases the total surface area of the steel, allowing for more efficient radiation and convection, which leads to a more stable room temperature.
Water must comply with GB1576 standards, with a pH of 9–12, chloride ≤ 300 mg/L, sulfate ≤ 150 mg/L, and dissolved oxygen ≤ 0.1 mg/L.
Yes, we provide four connection modes including same-side/opposite-side top and bottom inlets/outlets, as well as 90° vertical bottom connections.
Under normal operating conditions and proper water quality maintenance, these radiators have a service life of up to 15 years.
