The Leesgreen LSK-220 EX is a specialized control system engineered for the safe operation of ultraviolet disinfection reactors in hazardous environments. It monitors lamp intensity, ballast temperature, and water flow rates, providing critical safety interlocks and automated power adjustments to ensure consistent UV dosage while maintaining strict explosion-proof compliance.
Product Q&A
Q: What makes the “EX” version different from standard UV controllers? A: The EX designation indicates that the unit is housed in a flameproof or increased-safety enclosure, allowing it to be installed in Zone 1 or Zone 2 hazardous areas where flammable gases or vapors may be present.
Q: Can the LSK-220 EX monitor lamp life? A: Yes, the unit tracks cumulative operating hours and provides maintenance alerts when UV lamp efficiency drops below the required threshold for effective sterilization.
Q: Does it support remote emergency shutdown? A: Absolutely. It features dedicated dry-contact inputs for emergency stop integration and can be programmed to shut down the UV reactor instantly upon loss of cooling water or sensor failure.
