Wartsila Acquires Bolnes Motorenfabriek After-Sales Operations Wartsila Diesel has expanded its after-sales operations in the Nether- lands by acquiring the diesel engine after-sales operations of the Dutch company Bolnes Motorenfabriek B.V. The agreement includes the transfer of Bolnes' after-sales activi- ties to Wartsila Diesel's Dutch sub- sidiary Wartsila Diesel B.V., which will continue to run these opera- tions side by side with their pre- vious sales and servicing of Wartsila Diesel engines. Wartsila Diesel B.V. will concentrate their activities in Krimpen a/d Lek, in Rotterdam. Production of Bolnes engines will be phased down and Bolnes Motor- enfabriek will continue as Bolnes Multitechnik, a multi-technology subcontracting company.

BETTER MATERIALS! Bronze fittings, monel fastenings, 70% Cu-30% Ni Turbo Tube—stronger & more corrosion resistant than 90-10. Grooved Turbo Tube design gives more heat exchange than smooth, round or rectangular tubing. Consequently, a shorter cooler is required. . t. n SPIRAL GROOVES MAXIMIZE HEAT TRANSFER TURBO TUBE BETTER DESIGN! Aircraft-type flexible double o-ring construction, proven for over 35 years, eliminates problem of cracked brazed joints & expensive repair. Tubes can twist axially & longi- tudinally to conform to hull curvature. Can be recessed into hull! Streamlined design, unlike bulky box-type coolers, detachable in minutes without disturbing inboard plumbing. BETTER ENGINEERING! 50 years of experience allows us to publish over 700 computer-aided recommendations; hundreds more in our files. Complete line of models & sizes always in stock ensures fast delivery to cool any propulsion & generator engine, transmission, aftercooler & intercooler. w-a THE WALTER MACHINE CO.

Lee, N.J., recently announced the introduc- tion of a new Nirex ice machine for trawlers and fishing vessels, and a new Nirex freshwater distiller de- signed to meet the needs of small vessels. FWI 1250 Nirex freshwater ice machine. Designated the FWI Series, the Nirex ice machines are ideally suited for preserving and transport- ing fish over long distances. The freshwater ice produced will not freeze the fish flesh, but instead will maintain the fish at the correct tem- perature to insure the best quality. The machines are compact and come fully equipped with electric motors, control panel, instruments, safety devices and complete internal piping. They produce flake ice at an ideal temperature of 23° F. The ice fills all cavities and completely sur- rounds the fish, keeping it wet and cool, without freezing. Several models are available cov- ering capacities from 0.350 up to 10 tons/day. JWP-16-C40 Nirex freshwater distiller. The new Nirex freshwater distill- er, designated the JWSP-16-C40, is ideally suited for use on fishing ves- sels, workboats, supply boats and offshore rigs with small engines. It is designed to be easily connected to the diesel engine jacket water sys- tem and utilize the BTU's available in the JW system as the heat source. Steam can also be used if available. The JWSP-16-C40 has a capacity range of 100 to 1,850 gpd, depending on the heating medium and cooling water temperatures. Distillers can be dimensioned to suit any jacket water temperature from 131-194° F and any seawater temperature re- quired. The quantity of fresh water produced can be altered within each size by varying the number of plates in the heat exchanger assemblies. Weighing no more than 400 pounds, the JWSP-16-C40 can eas- ily be dismantled, allowing subas- semblies to be hand-carried by two persons into the engine room with- out making alterations in the room. The unit can be quickly reassem- bled—just bolt it together, hook it up to water and electrical lines, and start it up with the push of a button. It can be either deck, bulkhead or overhead mounted. The distiller is designed to oper- ate automatically under varying operating and weather conditions without any effects on salinity of the fresh water produced. Like all Alfa-Laval Nirex distill- ers, the JWSP-16-C series features titanium plate heat exchangers that eliminate corrosion problems and allow for increasing capacity simply by installing additional plates in both the condenser and evaporator. To further eliminate corrosion, the distiller cover is pressed from stain- less steel. After cleaning, normally required only once per year, the Nirex distiller delivers 100 percent capacity. The "C" in the designa- tion refers to the combined con- denser cooling and ejector water system, a key feature of the JWSP- 16-C40. This combined system low- ers installation costs and increases reliability of the distiller.
