(NEW BEDFORD, Mass.) — Imtra, a leading manufacturer and importer of high-quality solutions and products for the marine, energy and transportation markets, has launched a new line of commercial-grade side-power thrusters. Available in four tunnel sizes, the new products include proportional or on/off controls in AC-powered and hydraulic versions. The new thrusters are designed for commercial vessels and larger recreational yachts.
Available in 12-, 16-, 20- and 24-inch tunnels, the new side-power thrusters provide up to 3,000 pounds force of thrust. Each unit is built with dual, counter-rotating, bronze five-blade props for durability and efficiency. Their “Q-prop” design is quiet, and the dual counter-rotating props create equal thrust in both directions, especially when compared to single prop designs.
Side-power thrusters are lubricated with oil-fed gear lubrication. The 20- and 24-inch models can have their oil changed in-water, reducing operating costs by eliminating the need for a haul out. Side-power thrusters have compact and streamlined gearlegs that maximize water flow and thus increase thrust output.
The AC-powered models include a pre-programmed variable-frequency drive, EMC filter and proportional controllers. A wide range of lever/joystick controls are available to suit any application, and CANbus networking makes it simple to add multiple control stations with system monitoring.
Side-power hydraulic systems require no additional set-up at commissioning. The factory completely engineers the system including pump and valve specification, hose diameter and pressure ratings, electrical system, and all pumps and valves are pre-set for pressures and flows. In addition, IMTRA can provide complete hydraulic systems including the electrical control system for proportional or on/off controllers, powering not only the thrusters, but all other hydraulic applications – such as pot haulers, winches, cranes, steering, and crash and fire pumps.
The new thrusters are available through Imtra’s network of marine retailers, shipyards and marine retrofitters throughout North America. For information on IMTRA or its entire product line, (508) 995-7000 or visit www.imtra.com.
