This Fyra Freeze, freeze dryer Controller bundle is a very simple implementation that measures and controls both vacuum and shelf temperature with both heat and refrigeration.  This controller can be used to upgrade or retrofit a small to medium-sized freeze dryer where the original controller has failed or become problematic.  This can also be used as a control platform for new or custom-built freeze dryers.  This also adds a much needed vacuum control feature set and has both manual and automatic modes with logging capability.
Benefits:

1. Easy retrofit to older freeze dryers or those with failed controls
2. Adds vacuum level control and eliminates unreliable sensor components
3. Flexible manual mode control for research and automatic mode for hands free operation

Fyra Freeze Features:

• Automatic + manual control modes
• Shelf temp limit
• Freeze duration
• Drying duration
• Vacuum set point
• Alarm when shelf limit is exceeded or temp probe is lost
• Uses on type 531 vacuum sensor, two K temperature thermocouples (shelf + ambient)
• Heavy-duty quad solid-state relay
• VacStable vacuum level control valve which allows for precise vacuum control

FYRA Freeze Bundle Includes:

• FYRA Controller, rackmout version
• Sensors: Vacuum + 2 temperature 
• Solid state control relay
• Vacuum control valve
• TC wires cables, and power
• Wiring instructions
• Plumbing kit

How it Works:
The Fyra Freeze system controls AC actuated shelf heat, refrigeration system and a vacuum pump through a solid state relay.  Further, it manages the vacuum level through carefully dosing gas back into the chamber to maintain a particular pressure to improve drying and avoid losing desirable compounds.  It ties the measurement and control capability into a very simple to control and understand touch screen interface.
Applications

• Food freeze-drying and preservation
• Botanical (flower) drying
• Pharmaceuticals (API Manufacturing)
• Research

Vacuum Science Simplified
We know vacuum applications can get complicated. FYRA was created to deliver scientific measurement and vacuum control simply with easy integration into almost any system in the market.
FYRA Features:

• Easy integration into systems
• Capable of driving multiple types of sensors (ex. piezo, thermal, active, passive, and capacitance manometers)
• Has touchscreen and dial interface
• Intuitively display and manage multiple sensors + control points
• Dimensions: 1.7”H x 3.52”W x 5.35” Deep
• Comes standard with:
  • 10 Volt DC output for PLC integration
  • USB for data download + documentation of vacuum processing data-points
