Advantages compared to conventional systems

• In a vacuum the lower boiling point ensures gentile drying processes
• Thermoshelf heating reduces heat up times by more than 70% compared with sidewall or external heating
• No heat losses due to thermoshelf heating positioned next to the load
• No distorted temperature values due to temperature measuring directly at the thermoshelf
• Precise temperature control with separate microprocessor MLC, fuzzy logic, controller for each shelf
• Easy and precise vacuum adjustment of digital vacuum control
• Programmable vacuum drying cycles
