Description
LEESGREEN
TYPE: LSK-220 EX
CONTROL UNIT FOR PRESSURIZED EXPLOSION-PROOF UV REACTOR
EX CERT: GYB21.3554
UE: 220V
WORKING TEMP: -20~40℃
The Leesgreen LSK-220 Ex is a dedicated control unit designed to operate pressurised explosion-proof UV reactor systems in demanding marine environments. As a key component within a vessel’s marine control system, it governs the operational functions of the UV reactor, ensuring safe and reliable performance in areas classified as hazardous zones. Its explosion-proof rating and wide operating temperature range make it particularly suited to the rigorous conditions encountered aboard commercial and industrial vessels where environmental control and safety compliance are non-negotiable operational priorities.
Key Features
✓ Designed specifically as a control unit for pressurised explosion-proof UV reactors, managing reactor operation within certified hazardous area installations.
✓ Rated at 220V supply voltage with an operating temperature range of -20 to 40℃, suitable for variable shipboard ambient conditions.
✓ Carries explosion-proof certification reference GYB21.3554, confirming compliance with recognised Ex equipment standards for use in classified marine zones.
✓ Intended for installation in hazardous or pressurised equipment enclosures; mounting location and interface compatibility are subject to confirmation based on the specific reactor configuration.
✓ Replacement of this control unit restores full automated management of the UV reactor system, making it a critical service component for maintaining system uptime and operational safety.
Marine Applications
✓ Ballast water treatment systems utilising UV reactor technology aboard bulk carriers, tankers, and large cargo vessels.
✓ Hazardous area equipment installations on chemical tankers and LNG carriers where explosion-proof control components are mandatory.
✓ Offshore support vessels and platform supply vessels operating UV-based water treatment or sterilisation systems in Ex-rated spaces.
✓ Marine automation systems requiring reliable UV reactor management in engine rooms or pump rooms classified as hazardous zones.
✓ Newbuild and retrofit projects incorporating pressurised explosion-proof UV reactors as part of environmental compliance or water management systems.
