  3. 3. Operating Envelope Comparison
  4. 4. Operating Envelope Comparison Benchmark vs Competitive Scrolls
  5. 5. Bristol Benchmark Advantages <ul><li>Benchmark H71J </li></ul><ul><li>Not phase sensitive – operates equally well regardless of phasing </li></ul><ul><li>Full protected against thermal fault </li></ul><ul><li>No shut down noise </li></ul><ul><li>Internal suspension reduces vibration and absorbs start torque </li></ul><ul><li>Competitive applied cost </li></ul><ul><li>HP Scroll </li></ul><ul><li>Requires three phase protection </li></ul><ul><li>External thermostat recommended for protection against high discharge temperature </li></ul><ul><li>Shut down noise minimized but not eliminated </li></ul><ul><li>No internal suspension, requires generous tube flexibility to absorb start torque </li></ul><ul><li>Price Premium for Heat Pump performance </li></ul>
