LSR-3 Linseis Seebeck & Electric Resistivity Unit The Thermal power, thermoelectric power, or Seebeck coefficient of a material measures the magnitude of an induced thermoelectric voltage in response to a temperature difference across that material. The thermal power has units of (V/K). In recent years, much interest has been shown in various methods of direct conversion of heat into electricity. Waste heat from hot engines and combustion systems could save billions of dollars if it could be captured and converted into electricity via...

Paratherm — Heat Transfer Fluids
NF® (Non-Fouling) Heat Transfer Fluid that transition occurs, the faster the system will reach operating temperature. Paratherm NF has the lowest viscosity range of any mineral-oil based fluid. High heat transfer coefficients extend fluid life. In heat transfer fluids, the most important advantage of a high heat transfer coefficient is that it reduces the heater surface temperature required to achieve set-point temperature. Lower temperature means less thermal degradation which means longer life. Paratherm NF has the highest heat transfer...

Pittsburgh Corning (FOAMGLAS® insulation)
FOAMGLAS PFS Pool Fire Suppressant . This has led to the wide use of cellular glass insulation on piping and equipment requiring fire protection. Cellular glass also has low coefficients of expansion and thermal conductivity. This unique combination of properties - closed cell structure, inorganic composition and low coefficient of expansion - also renders the material a particularly effective tool for use in LNG pool fire suppression. These properties result in a material that maintains its buoyancy despite extreme temperature... (read more)
