LP Stingray products

The Stingray aquaculture net cleaner, developed by Lindgren-Pitman Inc, serves the aquaculture industry by efficiently cleaning fouled net pens. This innovative and patented machine is designed to lower operational costs, minimize maintenance, reduce CO2 emissions, improve the welfare of fish, and enhance safety without causing damage to the nets. Initial research highlighted that traditional high-pressure water cleaners were inefficient, resulting in over 80% power losses and ineffective removal of mussels, shells, and kelp. The Stingray incorporates a specialized low-speed propeller designed by experts in nuclear submarine technology. This electric-driven propeller uses a raked blade to efficiently remove fouling through the net wall without damaging it. Additionally, the Safetrak system features a urethane rubber track with stainless-steel studs that engage the net and facilitate movement above the waterline. By pressing directly on the net and employing articulated knuckles to shake off fouling, the Stingray provides a net-safe and fish-friendly solution. The machine significantly reduces decibel noise levels, benefiting fish welfare, and cuts CO2 emissions by up to 90%. The 2-meter variant requires only an 11 kW generator, making it an energy-efficient and reliable option for maintaining healthy aquaculture environments.
