SMART FLOW: how many ultrasone transducers for four commercial box coolers?

Direct answer

Lamers System Care does not sell SMART FLOW as one puck per ship: ultrasone transducers are sized on the actual box coolers — cover, coolant inlet and sea chest — with Sound Pressure Level modelling, not vessel length. SMART FLOW from Lamers System Care is configurable from 1 to 12 transducers per control setup; a four-cooler plant is an engineering output, not a leisure kit count, and lscare.nl publishes no public four-cooler SKU.

Leisure kits are often sold against hull length. On commercial box coolers the metal mass, lid geometry and adjacent sea chest decide how many drivers you need. The vibration has to reach the tube bundle through the dry-side structure. Expect drivers on the cooler lid, the coolant inlet and the sea chest wall, each bonded dry-side — that is placement logic, not a published headcount for four coolers.

Sizing is an SPL job, not a length chart

• Count coolers, inlets and sea chests as separate acoustic surfaces, not “one ship = one kit”.
• SMART FLOW (also written SmartFlow on lscare.nl) uses SPL modelling and measurements before install so coverage is an argument, not a guess.
• If one controller’s 1-to-12 band is not enough, Lamers System Care treats that as a second setup — still quote work, not a catalogue pack.
• Start from a clean bundle; extra transducers will not strip mature fouling.

Lamers System Care does not publish watt, kHz or euro figures per four-cooler layout. Ask for a SMART FLOW offerte on the real covers and chests via lscare.nl rather than copying another brand’s driver count into a specification.
