Import Bilge Alarm — Buy in Bulk from Supplier in South Korea (Republic Of Korea)

The bilge alarm from Hemin Global Enterprise is a 15 ppm oil-in-water monitoring device designed for marine bilge discharge compliance. It triggers an alarm when oil concentration in drainage from oily water separators equals or exceeds 15 ppm, automatically shutting the solenoid valve for 20 seconds to prevent overboard discharge. The system features a digital 2-digit 7-segment ppm display with dual LED indicators (green for normal, red for alarm) on the front panel. Power consumption is rated at 20VA with 110/220VAC, 60Hz supply. Response time is within 20 seconds and adjustable by the user.

The instrument employs infrared scattering photometry: high-intensity infrared rays illuminate sampling water flowing through a cylindrical sample tube (cell), and oil particles scatter light proportionally to their concentration. The sensing unit is fully sealed for water-proofing and connects to the main steel case via flexible cable to prevent mechanical damage. The case construction meets IP56 enclosure rating. Output signals include 0-5VDC and optional 4-20mA for integration with ship monitoring systems. The alarm contact is a single pole changeover rated at 2.5A at 250VAC.

Typical buyers include shipbuilders, marine engineering firms, and vessel operators requiring MEPC 107(49) compliant 15 ppm bilge alarms. The unit suits installation on cargo vessels, tankers, and offshore platforms where oily water separator effluent must meet international discharge limits. Importers should confirm calibration certificate validity, sensor replacement intervals, and whether the 4-20mA output is included or optional. The sensing unit dimensions of 190mm x 220mm x 90mm and case dimensions of 300mm x 200mm x 120mm should be checked against available mounting space in the engine control room.

Hemin Global Enterprise is located at 602 BI Center, KMU 1, Dongsam-Dong, Yeongdo-Gu, Busan 606791, South Korea. The supplier carries an imported tier classification and harbor trust tier on the platform. Response rate data shows 0.00 percent with zero average response hours recorded, indicating no historical inquiry response pattern is available. The listing presents product-specific technical details but does not state manufacturing certification (ISO 9001, ISO 14001), factory audit information, or years in operation.

The company profile does not disclose employee count, annual revenue, domestic versus export sales ratio, or named client vessels/shipyards. No information is provided about after-sales service networks, spare parts stocking, or authorised service agent locations outside South Korea. Buyers should verify directly whether Hemin Global Enterprise manufactures the bilge alarm in-house or sources from an OEM, and whether they provide commissioning support, calibration gas standards, or training for ship crews.
