ADL-ADU-HB – Advantage

SPACE-RAY Herringbone Tube heaters have many applications from factories and warehouses to sports halls, aircraft hangars, supermarkets, exhibition halls and retail premises. So no matter what the use, size or shape of your building you can rest assured that SPACE-RAY Radiant Herringbone heaters will suit your needs.

How do SPACE-RAY Radiant Tube heaters work? A gas fired flame within the Calorised Emitter Tube causes the heat to radiate invisible “black heat” energy. This energy gently warms surfaces and people without heating the air directly. Therefore SPACE-RAY Radiant Tube Heaters are highly fuel efficient and are an ideal total heating system or for zone/spot heating.
