BAC’s RS Remote Sump Tanks can easily be added to cooling towers, closedcircuit cooling towers, or evaporative condenser systems and are offered in avariety of sizes and materials. Remote sump tanks can eliminate other methods offreeze protection and are often installed indoors in a heated space to prevent freezingof the recirculating water during cold weather operation. Adding a remote sump tankcan simplify water treatment for multiple cell installations and facilitate dry operationof closed circuit cooling towers and evaporative condensers by eliminating the need todrain the cold water basin when switching from wet to dry operation.H2Q U E S T I O N S ?

Benefits, Custom Features& Options››Benefits LOW INSTALLED COST SUPPORT STEEL – All models mount directly onparallel I-beams. EASY MAINTENANCE INTERNAL ACCESS – The interior of the unit is easilyaccessible for adjusting the float valve, cleaning thestrainer, or flushing the remote sump tank. RELIABLE YEAR-ROUND OPERATION FREEZE PROTECTION – For reliable year-roundoperation, the remote sump tank offers freezeprotection when installed indoors in a heated area,eliminating the need to install cold water basinheaters. LONG SERVICE LIFE MATERIALS OF CONSTRUCTION – Available ingalvanized steel or with a thermosetting hybridpolymer.››Custom Features & Options CONSTRUCTION OPTIONS STANDARD CONSTRUCTIONG-235 hot-dip galvanized steel is the heaviestcommercially available galvanized steel, universallyrecognized for its strength and corrosion resistance.To assure long-life, G-235 hot-dip galvanized steel isused as the standard material of construction for allunits. All exposed cut edges are protected with a zincrich coating after fabrication to ensure the zinc richcorrosion barrier is maintained for all over protection.With proper maintenance and water treatment, G-235galvanized steel products will provide an excellentservice life under the operating conditions normallyencountered in comfort cooling and industrialapplications.Internal Access for Easy Maintenance THERMOSETTING HYBRID POLYMER (OPTION)A thermosetting hybrid polymer coating used toextend equipment life, is applied to select hot-dipgalvanized steel components of the remote sump tank.The thermosetting hybrid polymer has been testedto withstand 6,000 hours in a 5% salt spray withoutblistering, chipping, or loss of adhesion. HOT WELL/COLD WELL ARRANGEMENT (OPTION)A water tight center baffle is provided, along withadditional suction and drain connections and strainer, forseparate storage of hot and cold water. This arrangementis provided with a single make-up assembly. The hotwell/cold well arrangement is frequently used with highlyvariable loads to even out the load put on the evaporativecooling equipment. ELECTRIC WATER LEVEL CONTROL (OPTION)BAC Electric Water Level Controls (EWLC) are state-ofthe-art conductivity actuated, probe type liquid levelcontrols. The hermetically sealed EWLC is engineeredand manufactured specifically for use in evaporativecooling systems and are equipped with an error codeLED which illuminates to indicate status, includingwhen the water and/or probes are dirty. The EWLCoption replaces the standard mechanical make-up valve.EWLC is recommended when more precise water levelcontrol is required, in areas that experience sub-freezingconditions, and where the incoming supply waterpressure is outside the normal 15 to 50 psig pressurerange of the standard mechanical make-up valve. TANK COVERS (OPTION)Covers with lifting handles are available.H4Q U E S T I O N S ? C A L L 4 1 0 . 7 9 9 . 6 2 0 0 O R V I S I T W W W. B A LT I M O R E A I R C O I L . C O M

Structural SupportThe recommended support arrangement for the RS Remote Sump Tank consists of parallel structural members running thefull length of the unit, spaced as shown in the following drawings. In addition to providing adequate support, the membersalso serve to raise the unit above any solid foundation to assure access to the bottom of the unit. To support a RS RemoteSump Tank in an alternate support arrangement, consult your local BAC Representative.31 7/831 7/8UNITOUTLINE20 3/4UNITOUTLINE(4) 5/8 DIA. MOUNTING HOLES22 5/16(4) 5/8 DIA.
