Natural Gas Radiant Tube Heater RBT 20 LS - SPLUS

The natural gas radiant tube heater RBT 20 LS is a high-performance solution for heating high-ceiling industrial buildings.

Operating without air movement, this system ensures even heat distribution and optimal thermal comfort, even in large volumes. Its design reduces energy consumption while guaranteeing high efficiency. Available in several power ratings from 20 to 48 kW, the RBT LS is perfectly suited for demanding industrial applications.

High-Efficiency Radiant Heating

The radiant tube principle is based on infrared radiation: the heat produced does not warm the air but directly heats objects, surfaces, and people. This heating mode reproduces the effect of the sun, providing comfortable, constant, and even warmth. Thanks to its high-reflectivity aluminized steel reflectors, the RBT LS offers optimal thermal efficiency and consistent heat distribution throughout the covered area.

Energy Savings and Efficiency

With a radiation efficiency of 68%, the RBT 20 LS allows up to 30% energy savings compared to conventional heating. The energy produced is concentrated and diffused where it is needed, limiting losses. This high efficiency helps reduce gas consumption while increasing overall thermal comfort.

Comfort and Cleanliness of the Environment

Radiant heating generates no airflow or dust movement. This silent and clean operation makes it an ideal solution for workshops, warehouses, and production areas requiring a stable and particle-free atmosphere. Additionally, its extremely low noise level promotes a pleasant and serene working environment.

Easy Installation and Maintenance

Installed at height, the radiant tube frees up floor space, allowing optimization of available surface area for activity. Its compact size and minimal maintenance ensure sustainable and economical operation. Designed to run on natural gas or propane, it offers great installation flexibility according to site constraints.

Key Features of the RBT 20 LS

  • Energy savings: up to 30%
  • Heating without air movement or dust
