Helac Introduces Enclosed Hydraulic Valve Actuators

RFG Introduces New Waste Water Treatment System

RGF Marine Environmental

Technologies, Inc., a member of RGF

Environmental Group, has unveiled its newest waste water treatment and recycling system, the RGF Steam

Draygon Evaporator. The unit reportedly evaporates up to 99 per- cent of contaminated waste water, leaving only minimal residual waste for disposal.

The RGF Steam Draygon

Evaporator can reportedly process 250 to 400 gallons of waste water per day, operates automatically or by manual batch process, and incorpo- rates a self priming centrifugal pro- cessing pump. A solid state tempera- ture control provides accurate tem- perature settings while a PLC six probe sensor makes necessary adjust- ments for automatic operation. The

RGF Steam Draygon operates on kerosene, diesel fuel, natural gas or liquid petroleum gas, and can also use waste oil to fuel the burner, safely disposing of one waste while evaporating a waste stream.

RGF's water treatment system also incorporates a high flow exhaust fan and a serpentine heat exchager designed to increase the evaporation rate, prevent unnecessary loss of BTUs and reduce fuel cost. The Steam

Draygon features complete 304 and 316L stainless steel construction, a stainless automatic oil skimming belt and an UL approved process pump.

Helac's PVS Series hydraulic rotary valve actuators are now completely enclosed and sealed to meet IP66 specifications for pre- vention of dust and water ingress and con- tact with moving parts. The PVS Series combines Helac's patented, high torque design with fail-safe, spring return in an ultra-compact configuration. The large diameter center shaft features a hollow bore that permits coupling to the valve stem internally, facilitating direct mounting of the actuator to the valve bonnet without brack- ets or couplings. All of PVS' internal compo- nents and adjustment hardware are enclosed and sealed from the environment.

Standard cylinder seals are used throughout its steel construct to ensure leak-free opera- tion without drift. Options on the PVS series include limit and proximity switches, completely submersible designs, position feedback, manual override and metric mounting. Fail-safe valve open or closed positions are available, along with double-acting models.

Nelson Adds New Line Of

Koalescers

Nelson Division has added a new line of

UL marine listed koalescers to its line of standard spin-on koalescers. The UL list- ing makes it applicable to all marine engines using either diesel or gasoline fuels, and the UL versions can be used for both suction and pressure side applica- tions. The Nelson koalescer reportedly removes 99 percent of the free and emulsi- fied water in fuel, which can rob engines of power, destroy fuel injectors and pumps, corrode metal, generate rust and oxidize fuel into varnish. The removal of water from fuel protects the engine, allowing it to burn pure fuel and provide more power.

Nelson Division, a division of Nelson

Industries, Inc., is involved in the design and manufacture of exhaust and filtration systems.

The Fire Tube Cleaner (FTC), from Thomas C. Wilson, Inc., is an efficient tube cleaning system for two through four-in. tubes.

The FTC is made up of an elec- trically driven motor and a heavy duty, flexible shaft assembly that allows for the cleaning of tubes in condensers, boilers and heat exchangers in an one-person operation. The FTC collects soot and scale, both wet and dry, as it cleans with a simultaneous vacu- um feature, leaving boiler and maintenence personnel clean.

This 1-hp unit can also be used to clean chiller and absorption units by using different shafts and casings and brushes.

Maritime Reporter/Engineering News address 75 percent of ship- board pumping duties.

They include main engine cooling, auxiliary cooling water circuits, bilge systems, ballast systems and general service.

These units reportedly meet

Lloyd's, DNV, BV, GL, ABS and

RINA classification require- ments for unrestricted service.

Models in the range have capacities up to 550-cu-m/hr with heads of five to 38 m.

Standard specifications of all pumps in the range include: mechanical seal; pump shaft in stainless steel (316S); 50mm suction and delivery gauges; bronze casing (LG2); coupling guard; mounting feet; and alu- minium bronze impeller (ABI).

Targets Shorter Lead

Time

Hamworthy Marine of Poole,

U.K., has introduced a new production system for a range of its fast moving Dolphin cen- trifugal pumps. The produc- tion methods have been designed and the pump compo- nents speci- fied to ensure reduced delivery lead times.

The range features 15 models of the Dolphin centrifugal pumps, which
