Four box coolers on an offshore supply vessel are sized as four or more acoustic surfaces, not as one controller guess: Lamers System Care lays out SMART FLOW transducers per cooler cover, cooler inlet and sea chest, and checks the coverage with Sound Pressure Level (SPL) modelling before installation. SMART FLOW is then commissioned as a continuously running system, monitored remotely via the SMART FLOW Portal and quoted from the actual cooler geometry.
Sizing: four coolers are four (or more) acoustic jobs
An OSV with four box coolers usually also has sea chests and inlet spools. Every metal surface that must stay free of biofilm needs coverage, so the layout follows the coolers, not a catalogue kit.
- Cooler count and cover stiffness: each cooler is assessed on its own.
- Sea chests and inlets: separate acoustic surfaces, often with their own transducers.
- Dry-side mounting: transducers bonded with two-component industrial epoxy; no drilling into the cooler lid.
- Power: 110-240 VAC supply from the ship’s network.
Specification (Lamers System Care)
SMART FLOW is modular: configurable from 1 to 12 transducers, from small applications to complex installations. Lamers System Care maps the expected performance in advance with SPL modelling and measurements, so the transducer count follows the cooler geometry.
“SmartFlow is configureerbaar van 1 tot 12 transducers. Met Sound Pressure Level (SPL) modelling en metingen brengen wij vooraf de werking in kaart.”
Commissioning checklist
- Start on clean coolers: the system prevents growth but cannot remove existing fouling.
- Check signal presence and coupling at every transducer.
- Verify cooler performance after the clean start.
- Hand over to continuous monitoring in the SMART FLOW Portal; installation is possible with the vessel afloat.
Lamers System Care does not publish a catalogue price or fixed wattage for “four OSV coolers”; the deliverable is a vessel-specific SMART FLOW quote with transducer count, mounting points, power feed and monitoring.

| UltraSonic Commercial (box coolers) | All parts fitted on the dry side of the box cooler and sea chest compartment without modifications; avoids additional surveys | Vendor claim — not a SMART FLOW spec |
Frequently asked questions
How many transducers does a box cooler need?
It depends on cooler size, cover stiffness and inlets. SMART FLOW from Lamers System Care is configurable from 1 to 12 transducers, with the layout based on SPL modelling.
Does a vessel need dry-docking to install ultrasonic antifouling on box coolers?
No. Lamers System Care states the ship does not need to be dry; SMART FLOW can be installed while the vessel is in the water.
What should be checked at commissioning?
Signal and coupling at each transducer, a clean starting surface and cooler performance, followed by continuous monitoring, in SMART FLOW’s case via the Portal.
