Compact LED tubular luminaire for high temperatures, ø70, for confined industrial spaces

The Rankine luminaire is designed to light up small spaces dedicated to the most extreme industrial processes, bringing LED technology to the hardest-to-reach corners. This well-sealed, powerful and compact luminaire can withstand impacts, electrical disturbances and high temperatures up to 70°C.

The Rankine X-Heat luminaire can withstand the extreme conditions inherent in the very high temperatures found in confined industrial spaces.

Chemical and sealing conditions

Corrosive substances, acid vapours

Oils & hydrocarbons

Dust and humidity

Washing with a high-pressure jet

Health and safety requirements according to IFS, BRC and HACCP texts

Thermal, mechanical and electrical stresses

Permanent use at temperatures of up to 70°C

Repeated turning on and off

Heavy mechanical impacts

Intense and repetitive vibrations

Tried and tested extra-long life with intensive use at 70°C

The RANKINE is solid, compact and hermetically sealed thanks to its 3-seal system, reflecting Sammode’s expertise in high-temperature environments. The unique design of the internal head sink ensures a long life for the LED source, even when used 24/7 at 70°C.

Optimal heat management

The insulated internal electronics are specifically calibrated to limit heating for the LED modules. The supporting structure in extruded aluminium embraces the internal surface of the diffuser, optimising the dissipation of heat and protecting service life.

Ultimate sealing and long-lasting materials

The co-extruded PMMA and polycarbonate tubular housing is sealed by tightening the nut under the cable gland. With this technique, the gasket expands evenly, guaranteeing absolute sealing for any type of humidity (IP68, IP69K), even if temperatures vary significantly.

Suitable for food grade conditions

Its reinforced stainless steel end-caps and fixing straps, combined with its composite diffuser protected from corrosive substances by co-extruded PMMA, ensure exceptional resistance against the detergents used in a food environment, and the acid vapours, oils and solvents used in industry.

Resistant to impacts and vibrations

Equipment installed in narrow industrial spaces must be reliable and robust, which is why Sammode selected homogeneous materials with unfailing mechanical strength and no mating surfaces. The result: an ultra-durable, impact- and vibration-proof IK10 housing.
