Gas Radiant Heater RGI 97 S - 9.7 kW - SPLUS

SPLUS RGI 97 S Natural Gas Radiant Heater with Ionization

The RGI 97 S is a natural gas radiant heater with ionization designed to provide a high-performance solution for large spaces. It is ideally suited for warehouses, workshops, hangars, and places of worship.

Radiant Heating Technology

Operating on natural gas, this unit delivers gentle, even, and instant heat through its visible combustion system. Unlike convection systems, infrared radiant heating does not warm the ambient air but directly targets surfaces and people within the emission zone. This approach eliminates air movement and preserves atmospheric humidity.

Immediate Thermal Comfort

The infrared technology ensures rapid temperature rise and instant thermal comfort, even in open or partially insulated spaces. Occupants benefit from natural, uniform warmth without drafts or dry air sensations.

Power Suited for Large Volumes

With a heating output of 9.7 kW, the RGI 97 S efficiently heats expansive areas while ensuring consistent heat distribution. Particularly suitable for high-ceiling buildings, it maintains performance even with high ventilation rates. This balance of power, comfort, and energy control makes it a smart choice for professionals.

Optimized Energy Efficiency

The visible combustion and targeted radiation significantly reduce heat losses. This technology can reduce gas consumption by up to 25% compared to hot air systems. The radiant operation also limits air stratification, ensuring stable thermal efficiency over time and significantly reducing energy costs.

Flexible Installation and Reduced Maintenance

The RGI 97 S design allows for simple installation in two modes: ceiling-suspended or wall-mounted, depending on site constraints. Its compact structure facilitates integration without major construction work. The clean combustion system and robust components minimize maintenance and ensure long service life and reliable operation.

Application in Places of Worship

The direct radiation of the RGI 97 S proves particularly effective for heating churches, temples, or mosques. It allows heating only occupied areas such as pews or the altar, without wasting energy warming the entire volume. This targeted operation ensures immediate comfort while optimizing costs, ideal for spaces used intermittently.
