  1. Peltier Temperature Device - PTD

  2. PTD – Peltier Temperature Device Truly Peltier Heated Hood Patented Technology Temperature range: -40°C to 200°C Sliding Rail: Flexible Positioning Peltier Convection & Radiation MCR Integrated Control Boards Peltier Heated Basis Plate

  3. PTD – Peltier Temperature Device • Peltier heating and cooling • Temperature range: -40 – 180°C • Typical working range: -30 – 150°C • Advantages: - Fast, i.e. large heating and • cooling rates • - Easy to operate • - Small design possible • - Inexpensive • Disadvantages: - Counter cooling needed • - Aging effects at high temperatures (>150°C)

  4. PTD – Peltier Temperature Device • The PTD consisting of bottom plate and hood is an intelligent temperature control system based on • Conduction heating = bottom plate • Combined radiation and convection heating = Peltier hood • MCR integrated control boards for a direct temperature control (no external boxes) • ToolmasterTM configured Radiation Heating Forced Convection Heating Conduction Heating Forced convection heating can be used in combination with N2 gas to create a frost free, dry environment

  5. PTD – Peltier Temperature Device Excellent temperature control from the bottom to the top • Unique combination of Radiation, Convection (frost protection) & Conductive Heating / Cooling • Homogenous heating and cooling • Low temperature measurement without having • condensation (inert, dry) • frost formation Peltier-Hood Heating/Cooling byConvection and Radiation N2 Peltier Basis Temperature-Control by Conduction

  6. PTD – Peltier Temperature Device Features and benefits • Excellent heating and cooling characteristics • Temperature range -40°C to 200°C • Frost protection down to -40°C • Truly Peltier heated hood • Sliding rail for peltier hood • Quick Connect • ToolmasterTM for basis plate & hood • Optional TruGapTM • Control Boards are part of the MCR • Unique combination of radiation, convection (frost protection) & conductive heating and cooling • Certified temperature sensor • Almost constant counter cooling temperature over a wide working range • Optional Evaporation Blocker • Bi-Cone (Double-Cone) • Disposable cones, plates and dishes for the lower plate

  7. H-PTD – Peltier Heated Hood • Quick Connect • Toolmaster • Sliding Rail for flexible positioning of the peltier hood

  8. PTD – Peltier Temperature Device Peltier System with patented actively heated hood H-PTD200 (US Patent 6,571,610) Most people just use the Peltier controlled base plate Problem: Huge temperature gradients Solution: Actively heated peltier hood ( H-PTD200 ) Proof technology with virtually Gradient free sample area none passiv H-PTD 200 P-PTD 200 P-PTD 200 P-PTD 200

  9. PTD – Peltier Temperature Device Verification of the temperature in the measuring gap • Automatic temperature calibration routine (Rheometer Software) • Certified sensor • Calibration sensor in the measuring gap • Connection of the calibration sensor to the rheometer • Plug & play MCR

  10. PTD – Peltier Temperature Device • Temperature range: -40°C to 200°C • Uniform temperature controller and temperature range for basis plate and hood • Controller board for basis plate and hood included in the MCR (full control over the system) • Largest temperature range without changing the counter cooling temperature Maximum heating rate: 60 K/min* Maximum cooling rate: 50 K/min* Average heating rate: 16 K/min* Average cooling rate: 12 K/min* *) Please keep in mind that the sample temperature is much more important than the maximum heating rate
