Preliminary Fluid Selection• Dowtherm G
• Temperature Range – 20°F - 675°F• Cost – Unknown (Dr. Kandlikar said less than $5/gal)• Availability – Needs to be ordered (awaiting response from
supplier)• Low viscosity• Low Thermal Conductivity• Non-Toxic

TANK AND COMPONENTS, TUBING & PIPING
Friday, January 11, 2013 P13671 - Garlock Expansion Joint
Concept Generation & Selection
17
Preliminary Selections
Tank: Parker SMS30• 30 gallon steel tank• Lowest price, can be bought locally• Easy installation of heat cartridges due to rectangular
shape
Friday, January 11, 2013 P13671 - Garlock Expansion Joint
19
Preliminary Selections
Tank Insulation: High Temperature Fiberglass & rigid foam
• High Temperature Fiberglass close to tank• Temperature Range: 0°F to 450°F• High density
• Add cheap rigid foam to outer layer to help minimize heat loss over time
Friday, January 11, 2013 P13671 - Garlock Expansion Joint
21
Preliminary Selections
Tank Mixer• TBD, depending on tank
Tubing & Piping• Metal rigid piping • Metal braided flexible tubing

22
PUMP SELECTION
Friday, January 11, 2013 P13671 - Garlock Expansion Joint
Concept Generation & Selection
24
Preliminary Pump Selection
Gear Pump• Maximum temperature of up to 500°F• Maximum pressures from 250 psi to 500 psi• Maximum flow rates from 20 GPM to 120 GPM• Fluid Compatible• Small footprint – approximately 1 ft3 before motor• Maximum 1800 rpm

25
HEATING COMPONENTS
Friday, January 11, 2013 P13671 - Garlock Expansion Joint
Concept Generation & Selection
27
Preliminary Selection
Cartridge Heaters• Using multiple smaller heaters helps increase power
potential and thus decrease time to heat the fluid• Relatively low cost per Watt (~ $0.03/Watt)• Using multiple heaters allows for even distribution of
temperature• Drill holes in sides of tank to attach heaters
