  1. Stratos ECO Training ECM “Smart” Circulators for Heating, DHW Recirculation Systems ECO 16 FX ECO 16 F ECO 16 BFX Presentation Date – New Jan 2008 Stratos ECO Circulators

  2. WILO Small Wet Rotor CirculatorsECM “Smart” Automatically Controlled Circulators • Stratos ECO Cast Iron & Bronze • ECM (Electronically Communicated) technology • Smart pump adjusts flow to system changes • Auto setback • Anti-seizing feature • Easy wiring quick connectors • Easy set-up (∆p-v in feet of head via red button) • Interchangeable with all competitors • Replaces 12 competitor’s types • 115 and 230 volt, models, cast iron & bronze • Max temp 230 deg F, min temp 60 deg F • Maximum pressure 145 PSI • Minimum pressure – see sheet • Maximum wattage 59, minimum wattage 5.8 • Class “A” energy rating Eco 16 FX & BFX Model Eco 16 F Model

  3. Model Number Designation ECO 16 ( ) FX • 16 = Maximum Head in Feet (adjustable from 4’) • B = Pump Housing (Volute) Material • (B for Bronze, no Letter for Cast Iron) • FX = Pipe Connection • F = Flanged • FX = Flanged Rotated

  4. Benefits - External Fits all Competitors’ Models (2 Bolt Residential Flanges) 2 Allan Screw Connection Automatic Air Venting (Inspection and Service Screw) Red Button Sets Head (∆pv in feet) Also Activates/deactivates Setback

  5. Benefits – Electrical 115/1/60 & 230/1/60 Volt 2 Electrical Openings Wilo-quick connections

  6. Sizing Examples • Sizing Examples – Simplified Heating • Determine BTU’s and Temperature Differential (mostly given) • Calc Flow (USGPM) = BTU per hr/500 (constant)/temperature diff deg F • EG: 10 USGPM will pump 100,000 BTU/hour @ 20 deg F differential • Once flow known size pipe based on max velocity of 4 ft/sec • Higher velocities cause noise, erosion and air problems • Once pipe sized estimate friction loss • Manifold systems heads are not additive – use the highest loss loop • Once friction loss and flow are determined match point to curve • Remember to use the correct companion flanges • Rotate Inventory!

  7. Installation Instructions • Install with shaft horizontal • Pump in any direction (vertical, horizontal etc.) • If pumping vertical try to pump up (with air) • Locate in system where suction pressure as high as possible • Pump away from the thermal expansion tank! • Fluid should be relatively free of abrasive particles • Damages sleeve bearings in wet runners and mechanical seals in dry runners • Do not use any stop leak products (see label) • Install with terminal box @ 9:00, 12:00 or 3:00 positions • Installing @ 6:00 can allow fluid into terminal box during air bleeding • Do not install at the highest point (air) • Do not install at the lowest point (dirt) • Be careful with the suction side (laminar flow)

  8. Application Examples • Applications • Cast Iron (Ferrous) Models • Primary and Secondary Hot and Chilled Water Systems • Up to 50 % Maximum Glycol – DO NOT USE STOP LEAK PRODUCTS! • Closed loop (airless) hot and cold circulation systems (60 to 230 deg F) • Bronze (non-Ferrous) Models • Open loop systems (ie Domestic HW Recirculation) – Max Temp 150 deg F (66 deg C) • Higher temps can cause precipitation of Calcium in hard water applications • Maximum working pressure 145 PSI • Minimum inlet pressure • 0.7 PSI @ 122 deg F (50 deg C) • 4.4 PSI @ 203 deg F (95 deg C) • 14.5 PSI @ 230 deg F (110 deg C) • For indoor use only
