High-temperature ceramic infrared heaters are gas-fired radiant heaters that emit intense heat exactly where it is needed thanks to glowing ceramic tiles. With operating temperatures of 800 to 900 °C, they provide powerful and targeted radiant heat with high efficiency and low operating costs. Ceramic infrared heaters are particularly suitable for industrial halls, logistics premises and workshops with higher ceilings, and wherever direct radiant heat is required without unnecessary heating of the air.
We manufacture MK ceramic infrared heaters in two variants depending on the installation position.
Ceramic infrared heaters MK – overview of variants
MKV gas-fired ceramic infrared heaters are designed for horizontal installation under the ceiling and provide intense radiant heat directly into the heated zone. Thanks to the high temperature of the ceramic tiles, they ensure rapid heat-up and efficient heating of industrial halls, workshops and warehouses. They are ideal for spaces with greater clear height where targeted and economical heating is required without unnecessary heat losses.

Ceramic infrared heaters for intensive heating of industrial halls
Ceramic infrared heaters are designed for heating industrial halls, workshops and warehouse premises with greater clear height or higher heat losses. Thanks to the high temperature of the ceramic tiles, they generate intense radiant heat that acts directly on people, working areas and objects, rather than primarily on the air.
Compared to other types of radiant heating, they stand out for their very fast heat-up time and high radiant intensity. They represent an efficient solution particularly where a cost-effective gas supply is available and where targeted and immediate heating of specific zones is required.

MKS gas-fired ceramic infrared heaters are designed for wall mounting or installation above doors and entrance openings, where they provide intense radiant heat directly into the heated zone. They are intended for local and targeted heating of specific workplaces, loading ramps or areas with increased heat losses due to frequent door opening. Thanks to the high temperature of the ceramic tiles, they are also suitable for high halls where efficient and economical heating of working zones is required without unnecessary heat losses into the upper layers of the space.

Ceramic infrared heaters for intensive heating of industrial halls
MKS gas-fired ceramic infrared heaters are designed for heating industrial halls, workshops, warehouse premises and especially areas with increased heat losses, such as entrances, loading ramps or doors. Thanks to the high temperature of the ceramic tiles, they generate intense radiant heat that acts directly on people, working areas and objects, rather than primarily on the air.
Unlike large-area ceiling systems, they are designed for local and targeted heating of specific zones. They feature very fast heat-up and high radiant intensity, ensuring immediate thermal comfort even in spaces with frequent ventilation or door opening.
They represent an efficient solution particularly where a cost-effective gas supply is available and where economical, zoned and immediate heating is required without the need to heat the entire air volume.
