The greenhouse finned tube radiator is a high-efficiency heating device specially designed for greenhouses, agricultural growing facilities, warehouses, workshops, and large industrial spaces. It is widely used in greenhouse heating systems where rapid heat transfer, energy efficiency, and long service life are required.
The core structure consists of a steel base pipe (carbon steel tube) with spiral metal fins attached to the outer surface through high-frequency welding or spiral winding technology. This unique circular fin design significantly increases the heat dissipation area compared with traditional smooth pipes.
Due to its expanded surface area, the finned tube radiator provides several times or even dozens of times higher heat output than ordinary steel pipes, allowing fast and uniform temperature distribution throughout large indoor spaces.
The spiral fin structure increases the contact area between the radiator and surrounding air, improving heat exchange efficiency. It can quickly raise indoor temperatures and maintain stable heating performance, making it ideal for:
The radiator is generally manufactured using high-quality carbon steel as the base material.
Advantages include:
Since greenhouse environments usually contain high humidity and moisture, greenhouse finned tube radiators are commonly treated with:
These surface protections effectively improve corrosion resistance and help extend the service life, which can typically reach 8–20 years depending on operating conditions and maintenance.
The greenhouse finned tube radiator works by transferring heat through a heated medium flowing inside the steel tube. Heat is conducted from the pipe wall to the external fins, and the enlarged fin surface efficiently releases heat into the surrounding air.
It is compatible with multiple heat sources, including:
This makes it a flexible solution for different greenhouse heating projects and industrial heating applications.
The standard length of a single finned tube radiator is usually 6 meters, while customized lengths can be manufactured according to project requirements.
The pipe ends can be equipped with:
Multiple units can be installed through:
The flexible installation options allow easy integration into various greenhouse heating layouts.
