Laser Diagnostic Instruments at S.E.A Environment & Water Technologies Exhibition, AsiaWater 2020.

We are part of the EU Business Avenues in South East Asia Environment & Water Technologies Virtual Business Mission from 29 Nov to 3 Dec 2020, the leading biennial water & wastewater exhibition + conference, AsiaWater 2020.

An initiative funded by the EU helping European companies to establish business collaborations in Asia.

The EU Business Avenues strengthens the presence of EU companies in South East Asia, using Singapore as a hub.

With climate change and various environmental issues growing across South East Asia, the search for sustainable solutions that help reduce and recycle waste and improve resource efficiency has been ramped up.

Explore innovative solutions by European companies at the Environment and Water Technologies virtual business mission happening from 29 November to 3 December 2020, which will bring them to participate in the virtual exhibition of Asia's leading biennial water and wastewater exhibition and conference, AsiaWater 2020.

Since 2016, the EU Gateway | Business Avenues Programme has organised conferences in Asia for Environment & Water Technologies sector, and one more is scheduled to take place online at the AsiaWater 2020 virtual tradeshow. With 83% of the EU companies have shared that they established business collaborations from the mission previously.

Due to COVID-19 pandemic, EU Gateway | Business Avenues adapted by postponing the 2020 business mission in Singapore & Malaysia to the end of the year. The mission will be virtually co-located with AsiaWater 2020 in Kuala Lumpur for business-to-business meetings. In Singapore, the mission is supported by the Public Utility Board and the National Environment Agency.

The best instruments are built from constant improvements: thoroughly listening & responding to user feedback.

EU solutions are once more going to make their way to the South East Asian markets, especially advanced solutions focused on new water and desalinisation, including membrane technology for desalinated water, biological processes, chemical redox, sensors and instrumentation, sludge and brine management, watershed management, decentralised water treatment technologies, industrial water technologies and household water management.

Being in business since 1991, LDI originally started by building sophisticated aircraft and ship-mounted laser based (LiDAR) systems that can detect sub-surface oil spills over many miles. The demand for a simpler, more flexible device that would catch early surface spills in real-time led us to develop ROW, which is now installed in industrial and public water facilities around the world.

We hold nine core technological patents and continue to innovate our products. We aim to ensure that industrial processes remain safe and risks to the environment are minimalised. Our non-contact technology puts our products at the forefront of easy to use instrument for water monitoring. Because remote sensing is our passion, you can count on us standing by your side for years.

ROW is a (oil on water) hydrocarbon detector with the potential applications extending beyond oil facilities.

The ROW provides early warning against oil spills, so you can react quickly and effectively.

There are a diverse number of applications for the ROW oil on water detector. Major industrial facilities like power generation plants, manufacturing plants and even airports use or store hydrocarbons in one form or another.
Given accidental spills and leaks can happen at anytime. Then, there are the waste water treatment plants or desalination plants who want to protect their facilities from external oil spills, whether its from tanker traffic or industrial oil spills.

24/7 monitoring.
For industrial or environmental water monitoring.

The ROW detects the most common oils used across multiple industries from heavy oils (crude, bunker fuels etc.) to medium (diesel, lubricant etc.) and even light fractions (kerosene, jet fuel etc.).

    Got questions?

    We are focused on providing our clients with the highest
    level of quality and excellent customer support.

    1. Can ROW be mounted on a buoy or an UAV?

    Yes, speak with us today to discuss available options buoy-based ROW.​ For UAV, it can and we are already working with partners on such systems. Sign up to our newsletter to receive updates for availability.

    2. Is the ROW able to detect oil in all weather conditions?

    Yes. For areas prone to fog, we recommend installing the ROW closer to targets to improve the effectiveness of the device as low cloud coverage scatters the signal to the device.

    3. What is the area covered by the field of view?

    The field of view of ROW is 0.05 – 0.4 m (Ø), focusing on this size of area allows the device to limit the averaged signal measured from the waters surface to reduce false alarms and increase sensitivity. Because oil spreads rapidly on water, in practice the area of water protected is much larger.


    Our Portfolio

    Taking the Industry Forward.

    At the cutting-edge of fluorescence based optics, LDI's ROW instrument is the fast, value-added solution for detecting oil spills for water monitoring. We maintain close co-operation with research institutes and industrial companies from Estonia, across Europe to North America.
