Drying ovens, large capacity, Heratherm® General Protocol and Advanced Protocol series

Supplier: Thermo Scientific
Heratherm®
Heratherm® large capacity ovens were designed for larger samples or high sample volume. All models have a large, easy to view, vacuum fluorescence display and simple to use touch button operation which is controlled by a microprocessor and automatic over-temperature alarm system to protect samples. All units are available in convenient 230 V version - no special connection required.

General Protocol ovens

The General Protocol ovens provide gentle heating via natural convection ideal for high capacity routine drying and heating applications. Units have corrosion-resistant stainless steel (1.4016) inner chambers, an intuitive user interface, easy to read display and lockable castors for easy set up, stability and mobility in the lab. There is a choice of 2 sizes, 400 or 750 litres, the larger unit is also available in 400 V for high temperatures and fastest heat-up and recovery times.

  • Low overall energy consumption: Up to 25% energy savings compared to conventional ovens
  • Protect delicate samples while still offering a uniformity of ± 3,0 °C and temperature stability of 0,5 °C at 150 °C
  • Doors can be opened over 180° for ease of access and units have easy to remove shelves for cleaning
  • Timer function to program start or switch off times for additional energy savings

Advanced Protocol ovens

The Heratherm® Advanced Protocol ovens offer mechanical convection via a 2-speed fan for faster drying and better temperature stability and uniformity. Units have resistant stainless steel (1.4301) inner chambers and access port for external sensors for independent data monitoring, or other devices for specific test set ups. Greater flexibility, accuracy and dependability are provided through a wide range of additional features. There is a choice of 2 sizes, 400 or 750 litres, the larger unit is also available in 400 V for high temperatures for up to 300 °C and fast heat-up.

  • Fan has low speed for applications that require minimal airflow (e.g. drying of powders), or high speed for fastest drying and heating, and best temperature stability and uniformity
  • Units offer a simple calibration routine to ensure temperature compliance over time
  • Programmable controller for pre-defined temperature ramps, up to 10 temperature steps can be defined per program
  • Fan speed and damper position are controlled electronically, and can be changed for every program step individually for maximum process flexibility
  • Up to 10 programs can be saved for repeating processes quickly and easily
  • Sophisticated timer provides choice of simple on/off timer, recurring weekly timer or set oven activity based on the 24 hour clock

Delivery information: Supplied with 2 shelves, additional shelves are available as optional accessories.
