High-Efficiency Cartridges

Key To Top Performance

In MMC Clarifiers

MMC International Corporation,

In wood, N.Y., reports that top per- formance in a clarifier-coalescer re- sults from the way MMC units are designed with inexpensive cartridge elements that are simple to remove and replace. This makes it extremely easy for an operator to keep the clarifier-coalescer functioning at peak efficiency as it removes dam- age-causing water and solid con- taminants present in lube, fuel and hydraulic oil systems.

MMC clarifier-coalescers are built to remove over 99 percent of the free water present in oil in a single pass because of the way the built-in wa- ter separator screen acts in conjunc- tion with the filter cartridge. MMC reports that this process also re- moves 99.9 percent of all solid sub- stances and the oil that is returned to the system, therefore, does not carry any foreign particles that could cause erosion, corrosion, or other- wise impede the efficiency of the system.

MMC was founded in 1939 and is a major manufacturer of electronic gauging tapes of all kinds, C-L cou- plings and other speciality products for the marine and other industries.

Naval ships, fleet oilers, commercial containerships, tankers and dredges are successfully finding new ways to operate more efficiently at lower cost, by utilizing

Tranter's unsurpassed plate-type heat exchanger technology. Schematics presented here illustrate typical ways they are doing it.

Superchanger® plate and frame heat exchangers are used in a wide variety of shipboard applications—particularly for cooling main engine jacket water and cooling main engine lube oil with fresh water or sea- water; cooling the ship's central fresh water; cooling electronic equipment; or recovering heat from condensate. They are far more effi- cient than tubular systems, and provide heat transfer coefficients from two to five times greater than those achieved by shell and tube units. They also require 10% to 50% less deck space and weigh up to one-sixth less.

Superchanger units can be equipped with titanium plates which offer the best resistance to corrosion and erosion when exposed to seawater. Intermixing or cross-contamination of hot and cold liquids is virtually impossible.

Low fouling rates reduce cleaning require- ments for Superchanger units, that are designed for easy maintenance. They can be cleaned-in-place by backflushing, or quickly disassembled by hand, cleaned and put back in operation.

Platecoil® prime surface heat exchangers offer optimum temperature control. A Platecoil bank-in-tank unit provides wide interspaces for effectively passing solids while efficiently heating seawater containing oil from spills.

Platecoil bayonet heaters provide a large amount of efficient primary heating surface in a single unit for maintaining desired temper- atures in storage tanks. These heaters help promote convection currents for better heat transfer rates and tank temperature uniformity.

Platecoil suction heaters provide immediate heating for pumping oil out of tanks.

Tranter plate-type heat exchangers can be supplied in full compliance with codes and specifications as required by the ABS; the

U.S. Coast Guard; shock testing per MIL-S-

Circle 302 on Reader Service Card 901C; vibration testing per MIL-STD-167-1; and ASME U stamp per Sec. VIII Div. 1.

MAN B&W Diesel Offers

Two New Free Brochures

MAN B&W Diesel A/S, of

Copenhagen, Denmark, has two free, color brochures available, the 20-page "Two-Stroke MC Engines -

Revised S80MC, L42MC, L35MC" (No. 253) and the 26-page "Basic

Principles of Ship Propulsion" (No. 254).

The MC Engine brochure pro- vides exceptional detail on the company's line of MC engines, be- ginning with explanations of the engine's development history and the types of units in the MC engine program.

Through highly detailed photo- graphs, drawings and artists rendi- tions, the construction and design of every major component of the MC engine is fully described in the Main

Design Topics section.

The remaining six pages provide power, speed and SFOC main di- mensions and dry mass tons data for each type of MC engine.

The Basic Principles of Ship Pro- pulsion brochure explains some el- ementary terms and principles in ship propulsion and design with the assistance of technical graphs, draw- ings and formulas.

Chapter one provides some basic explanations of ship definitions and hull resistance principles. The sec- ond chapter describes propeller pro- pulsion and the last chapter details engine layout and load diagrams.

Hagglunds Denison Offers 20-Page Brochure About

Its Axial Piston Pumps

Hagglunds Denison is now offer- ing an updated 20-page brochure describing its series PV open loop variable displacement axial piston pumps.

The hydraulic pumps, available in five sizes ranging from 0.88 to 3.78 in 3/rev., are thoroughly ex- plained through the use of schemat- ics and dimensional charts.

Features, benefits and general characteristics are also provided, including a narrative about the product's pressure compensator con- trol feature. The pressure compen- sator control allows the pump to deliver full volume from the outlet port until the pressure rises to the value set by the control.

A chart of higher speed guide- lines for each of the five units, a comparison of solid contamination classification systems, technical data conversions, and specification units are also included.

Hagglunds Denison is a leading manufacturer of hydraulic equip- ment components and systems for many areas in the industrial field.
