HSI® Receives DNV GL Type-Approval for Its TRO Sensor

January 20, 2021 – Recently, Halogen Systems Inc. has gained more recognition and significant approvals on its Amperometric DPI (direct pipe insertion) TRO (total residual oxidant) sensor. They have just been awarded DNV GL type approval for their ballast water management system (BWMS) sensor, which measures TRO in ballast water for applications with salinity levels of 0.2 PSU and higher.

President of Halogen Systems, Michael Silveri, relays: “There is now a low-maintenance alternative to DPD instruments for BWMS. Although we have delivered over 2,000 sensors for BWMS, DNV GL-type approval of our Amperometric TRO sensor for both hazardous and non-hazardous locations is excellent news. We have worked hard to offer shipowners a simple-to-install, reliable, low-maintenance DPI TRO sensor. The sensor performance has already been evaluated by the Alliance for Coastal Technologies (www.act-us.info/evaluations.php). Our sensor is not affected by flow changes, is self-cleaning, and is covered by 11 patents worldwide.”

Commenting on Halogen Systems’ unique DPI TRO sensor, Kevin Reynolds of OneTank states: “We have done extensive testing of this unit and found it to be a robust marine-grade field device. We like that the unit mounts right into the ballast water pipe. This eliminates the need for sample tubes, sample pumps, and reagents.

Looking forward to seeing this on many marine vessels and ballast water treatment systems.”

Steffen Schloericke – le technicien en chef de RWO/Veolia a déclaré : “L'unité RWO de Veolia a reçu son approbation finale de l'OMI pour son système de traitement des eaux de ballast utilisant le capteur ampérométrique TRO de Halogen. Nous sommes satisfaits du fonctionnement, de la fiabilité et des performances des capteurs.”

“BWMS designers should look closely at the Halogen TRO sensor. There are lower installation and maintenance costs, and it is easier to configure with far fewer parts. Its accuracy is the same level as the DPD method.” Said Cheon-Il, Kang / Director (TOMA) for Shin Woo E&T Co Ltd, “To comply with the SDL (system design limitation), IMO requires measurement and recording of the TRO, salinity, and temperature. Halogen Systems TRO sensor measures it all.”

Jaebin Yi, the Assistant Manager of the BWMS Team for AQUASTAR Co Ltd, says: “As a technical engineer for AQUASTAR, I would like to congratulate the Halogen Systems team on their DNV GL type approval. We are impressed with the sensor’s reliability, simplicity, and low operational cost (no reagents required). We look forward to using it in our ballast water system.”

Selon Silveri, “Le coût de notre capteur de type EX peut être la moitié du coût d'un instrument DPD. De plus, aucun réactif n'est nécessaire, ce qui représente une autre économie substantielle.”
