System Specifications

Vacuum System

The vacuum pump installed in FD-5RS system is a 2-stage oil sealed rotary vane pump.

A butterfly valve is installed on vacuum pipe for pump isolation, and is pneumatically operated. Capable of automatic close once electric interrupt.

Refrigeration System

Water cooling method, semi-hermetic compressor system. Chilling shelves in pre-freezing stage, and chilling condenser in drying stages.

Fluid Transfer System

Fluid circulates inside sandwich type shelves, which can be heated or chilled. Shelves heating through electric heater, and chilling through plate heat exchanger. PID control technology, precise control of temperature.

Controller and Measuring Apparatus

Temperature Sensors

PT100A probes for fluid, shelves, products and condenser coils temperature measure and control.

Vacuum Gauges

Pirani type vacuum gauges for drying chamber pressure measurement.
