MEDC CU1 Combination Sounder Beacon Range

Eaton’s Crouse-Hinds series MEDC CU1 combination sounder/beacon range is engineered for hazardous and potentially explosive atmospheres. Designed for oil, gas, and petrochemical industries, it is suitable for marine, onshore, and offshore environments.

The CU1 delivers a powerful sound output of up to 116dB(A) and beacon tube energy of up to 10 joules, ensuring clear audible and visual warnings in critical conditions.

Constructed with UV-stable glass-reinforced polyester for flamepaths, flare, and body, and fitted with stainless steel screws and a robust mounting stirrup, the CU1 guarantees corrosion resistance and long-term durability in harsh environments.
