100% stainless steel, embedded with rear opening, for zones with a controlled atmosphere

The Calmette is an original top-opening embedded LED and ideal for lighting in zones with controlled atmospheres. This well-sealed luminaire is ideal for food environments where health and safety are critical thanks to its materials with excellent mechanical and chemical resistance.

The Calmette luminaire can withstand the conditions faced in zones with controlled atmospheres.

Chemical and sealing conditions

Corrosive substances, acid vapours

All types of 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 40°C

Extreme variation in temperature

Repeated turning on and off

Mechanical impacts

Voltage surges up to 4 kV, power surges

Optimal health and safety

The CALMETTE is ideal in sterile zones and easy to disinfect thanks to a smooth front panel. It can also be embedded from below in the load-bearing ceiling. The luminaire is sealed by adding a bead of silicone between the front panel frame and the ceiling, and securing with 2 screw-on brackets with threaded rods on the back.

Top access for servicing

The CALMETTE is fitted with a 2-part casing (Clean© system). The lower casing is closed with a PMMA cover able to withstand detergents and containing high-performance aluminium reflectors. The removable top cover with 2 handles contains the LED driver and sources. Maintenance can be carried out safely outside of the production zone.

Ultra-durable materials suitable for food use

Extremely aggressive detergents are required on a daily basis to ensure high sanitary levels in clean rooms. Thanks to its PMMA cover with a stainless steel frame, the CALMETTE is unaffected by corrosion, and meets food safety regulations helping to ensure compliance with IFS, BRC and HACCP requirements for food sites.

Plug & Play connection

Installation in record time and risk-free operations above the load-bearing ceiling, thanks to a pluggable connector with a quick locking system. This luminaire is designed to withstand impacts, and remains hermetically sealed, even when open, preventing dust from entering.

Durable industrial electronics

Even the very best housing cannot stand up to the potential effects of an at-risk network. With this in mind, Sammode has opted for the most reliable components available, designed to withstand electrical disturbance, voltage surges and vibrations. The result: a long-lasting solution with an 8-year warranty, including for intensive use.
