Single StageHorizontal and Vertical DesignsUp to 4,000 HP (2,980 KW) API 611 Compliant

COPPUS Steam Turbines

COPPUS RLHA STEAM TURBINESThe RLHA turbine is an axial split horizontal turbine withsplit sleeve bearings, available in 3 frame sizes offeringup to 4,000 HP (2,980 kw). The axial split casing allowseasy access for on-site inspection and repair. The time-

RLHB featuresrugged anti-frictionjournal bearings.

For over 80 years COPPUS steamturbines have been recognized aroundthe world as rugged, versatiledrive solutions for lubeoil pumps, feedwater pumps,fans, genera-tors and othermechanical driveapplications. COPPUSturbines are routinely specified by thepetroleum, petrochemical, chemical, sugar, paper, foodprocessing and other industries that require continuousor stand-by emergency power.

tested reliability of the RLHA turbine makes it an idealselection for continuous operation applications for pumps,fans and generators operating in the most demanding indus-trial environments.

The RLHB offers anti-friction journal bearings, in place ofthe split sleeve bearings found on the RLHA, for applicationswhere quick starts are required. The RLHB also takesadvantage of oil ring or oil mist lubrication systems, eliminat-ing the need for higher cost forced feed lubrication for speedsup to 5,000 RPM.

COPPUS Steam Turbines

The RLA is a radially split horizontal turbine available in 8frame sizes offering 1 to

1000 HP(745 KW). The RLA

has a reputation as alow maintenance,easy to operateworkhorse. Field

proven to be an idealchoice for an economical

backup or continuous drive forpumps and fans.

COPPUS RLA STEAM TURBINES

Standard features on COPPUS Turbines include: Meet or exceed strict API 611 requirements. Overspeed mechanical trip valve. Snap-acting overspeed trip. Woodward TG direct drive oil relay governor. Constant level sight-feed oilers. Stiff shaft construction with single disc wheel located between bearings.

The RLVA turbine offers all the same features as theRLA with the added benefit of its space saving verticaldesign. Available in 8 frame sizes to meet a wide varietyof applications that includes pump drives for on boardships, and pump and fan drives for oil refineries, gaspipe lines and other industries where space is limited.

RLVA turbines are designed to meet API 611, NEMAand marine standards. Configurations are available for awide range of shaft extensions, thrust bearings andflange mounting arragements.

COPPUS Steam Turbines

COPPUSIn accordance with API 611standards.The snap-acting bolt type trip mecha-nism introduced by COPPUS in themid 80s set new industry standardsfor Overspeed Trip Systems.

The independent system stops theturbine under any load condition byactivating the force-actuated trip valve.

It is capable of threeconsecutive non-trending trip-outswithin +/-2% of settrip speed.

The OverspeedTrip Collar, installed

on the turbine shaft,houses an adjustable, spring loadedbolt. The bolt is retained until a pre-selected trip speed is reached. Whenthe turbine shaft exceeds the se-lected speed the bolt is instantlyreleased to unlatch the trip valve. Thesnap-actiontripping ispositive,preciseandrepeatable.

The Overspeed Trip Valvesare designed to minimize pressuredrop ensuring the highest availablepressure at the nozzle ring for doingwork.

When released by the Over-speed Tripmechanismor themanual triplever the

valve is instantlyclosed to shut offsteam. The single-seated valve will

bring a fully, unloadedturbine to a completestop.

For manual resetting against full-linepressure, a pilot valve relieves unbal-anced pressure.

Manual speed changer. Single piece contoured Curtis type wheel.

Optional Features for COPPUSTurbines Include: Forged steel wheels. Special shaft materials. Part load and overload hand valves. Kingsbury thrust bearings.

Copper free construction for corrosive atmospheres.

Single row wheels. Lagging, blanket type insulation.

High back pressure construction. Electronic or hydraulic NEMA Class D governors and variablespeed controls.

Solenoid trips for remote shutdown. Extended inlet pressure and temperature constructions.
