Detailed information

  • 01SV

    Drain Transfer Issues I am doing the drain transfer alone, so I cannot monitor it until it is full. ⇒ Improvement Point I started using the bell-type DLC-100B. Since it is a bell type with a loud volume of 80 decibels, I can work confidently even while facing backward.

  • 04SV

    Discharge of Ship Waste Oil on Land Issues Carelessly spilling waste oil can violate the "MARPOL Convention" and the "Law on the Prevention of Marine Pollution and Maritime Disasters," resulting in hefty fines. ⇒ Points for Improvement We have started using the bell-type DLC-100B. It is a bell-type with a loud volume of 80 decibels, which can alert crew members on deck.

  • 03

    Automatic Collection of Waste Cooking Oil - Internet Issues Sometimes the waste oil overflowed from the drum, causing problems. ⇒ Improvement Points We installed a contact signal type DLC-100. When the oil level approaches full, a signal is sent, and the full signal is transmitted to the collection headquarters via the internet transmitter, allowing the service provider to come for a speedy collection.

  • 07

    Refilling hydraulic oil Issues Sometimes the hydraulic oil overflowed from the drum, causing problems. ⇒ Improvement points Installed a warning light type DLC-100L. The lamp lights up when the oil is close to full, preventing overflow even if there is remaining oil. The finish has become cleaner.

  • 09

    Automatic Switching of Drum Cans Issues Waste liquid is stored in drum cans, but there was a problem with automatic switching. ⇒ Improvement Points Installed a contact signal type DLC-100. When the waste liquid approaches full, a signal is triggered to switch the piping with an electric valve. This eliminated the need for manual intervention and reduced the risk of waste liquid leakage.

  • 12

    Liquid and Oil Level Management and Automatic Replenishment Issues It was problematic when liquid or oil suddenly ran out. ⇒ Improvement Points An analog type DLC-800A was installed. When the liquid or oil level gets low, a signal is sent, and through the internet transmitter, a low level signal is sent to the materials management department, allowing the supplier to come quickly for replenishment.

  • 13

    Refilling Waste Oil Issues Since we are refilling waste oil, we don't realize it's full until it overflows. ⇒ Improvement Point We started using the bell-type DLC-100B. It's a bell-type with a loud 80 horn, so we can feel secure even when working in situations where we can't see inside.

  • 14

    Low hydraulic oil level warning Issues We were troubled by the sudden depletion of hydraulic oil. ⇒ Improvement Points We installed the indicator light type DLC-800L. When the hydraulic oil level is low, the red light illuminates, making inventory management easier. Production has also become smoother.

  • 15

    Low Coolant Oil Level Alarm Issues We were troubled by the sudden depletion of coolant oil. ⇒ Improvement Points We installed the indicator light type DLC-800L. When the coolant oil level gets low, a red light illuminates, making inventory management much easier. Production has also become smoother.
