Equipment Used Afloat and Ashore Small Refrigerator and Water Cooler Developed for Use on Shipboard— Compact, Light weight Condensing Unit for Geared Turbine Towboat duced by the Brunswick-Kroe- schell Co., engineers and manufac- turers of refrigerating machinery, New Brunswick, N. J. will be of in- terest to marine users to fulfill those needs for which the installation of the company’s other refrigerating equipment would be uneconomical. The experience of the manufacturer with problems on shipboard has re- sulted in the design of apparatus especially adaptable for this class of trade. The B-K Junior, as the small unit is called, is constructed along simple rugged lines and contains no intri- eate or complicated mechanism. It operates on the same refrigerating cycle as the larger Brunswick-Kroe- schell compressors. The entire con- densing unit, namely, the compres- sor, condenser and motor, is mount- ed on a single compact base, but at the same time all parts are readily accessible for adjustment or repair, a most important factor in marine refrigeration. Te small refrigerating unit pro- Model LP-150 Refrigerator, Brunswick- Kroeschell Product The compressor is air cooled, but either air cooled or water cooled condensers may be furnished as standard, depending upon the service for which the unit is intended. Evaporator coils are designed to fit any type of refrigerator or any small storage compartment. Control is completely automatic, a pressure- stat or thermostat being used which is of such design that it cannot be affected by the most extreme rolling or pitching of the vessel. Where a single machine operates on more than one refrigerator, or on a refrig- erator or scuttle butt, individual au- tomatic control is maintained in each unit to be cooled. 60 Water Cooler, Bubbler Type, Made by Brunswick-Kroeschell Co. The small unit is manufactured in sizes requiring from 1/6 horsepower to 1% horsepower motors. Where electric current is not available, the set may be equipped with a small gas engine connected to the compressor by means of V belt drive. The en- gine is mounted on a common base with the entire condensing unit. In addition to the refrigerating unit itself, there are available indi- vidual refrigerators, ice cream cabi- nets, scuttle butts and ice making sets of size and style most suitable for the specific need of each vessel. The refrigerating unit may be con- tained in the base of the refrigerator or scuttle butt, if desired, in such a manner that the entire equipment will be self-contained. Repair parts are available at various ports. This: unit <is recommended for small yachts, tug boats, small dredges and _ vessels having limited refrig- eration requirements as well as for larger ves- sels for cooling isolated pantry and small spe- cial refrigerators, scut- tle butts, ice cream cabinets, ete., where the location makes it impossible or undesir- able to connect into the central refrigerat- ing system. The evap- orator coils may be equipped with trays for the manufacture of ice cubes, and where a MARINE REVIEw—June, 1931 Compact condensing unit of 1020 square feet—Installed in Turbine geared tug Harry B. Williams built for Great Lakes Dredge & large number of ice cubes is required, special ice cube making sets may be furnished. Marine Condensing Unit Has Novel Features HE novel 1020 square feet con- densing unit illustrated on this page, designed and built at the South Philadelphia works of the Westing- house Electric & Mfg. Co., is said to be the smallest, most compact, light- weight assembly of marine auxiliaries ever built. One foundation supports four pieces of apparatus, the main condenser, circulating pump, air ejec- tor, and the oil cooler. The double- banked two-stage steam jet air ejector is located on top of the main conden- ser and on the right-hand end built into the water box is the turbine- driven propeller-type circulating pump. Mounted on the side is the single-pass oil cooler which receives water from the main injection. The steel plate shown in front is one of two supports which form a founda- tion for the complete unit. The posi- tion of the exhaust opening and the use of flexible supporting plates make an expansion joint unnecessary. When expansion occurs the plates simply give, and the whole condenser moves slightly to one side. This condenser will be part of the equipment for the first geared-turbine tugboat in the world and the first geared-turbine vessel ever to be placed in service on the Great Lakes. The towboat in which this condenser is installed was launched March 21, at Manitowoc, Wis., and christened the Harry B. WitxirAMs for the treasurer of the Great Lakes Dredge & Dock Co., owner.
