Control System Overview

Display & Interface

  • 5.4” LCD Touch Screen Display:

    • Simultaneously shows all main parameters including cold trap temperature, vacuum degree, sample temperature, and shelf temperature.

  • Schematic Diagram:

    • Graphic display of the equipment’s operating components, allowing users to view the working status of each part.

Pre-Cooling & Preheating Functions

  • Cold Trap Pre-Cooling & Vacuum Pump Preheating:

    • User-set timing options within the system ensure optimal preparation for freeze-drying operations.

  • Status Indication:

    • Displays the current running status—normal or abnormal—using numerical color indicators.

Built-In Data & Relationship Display

  • Saturated Vapor Pressure & Temperature Table:

    • Directly displays the corresponding relationship between saturated vapor pressure and temperature for informed process control.

Key Operational Features

  • One-Key Operation:

    • Extremely simple to operate; no special professional training required.

  • Safety Protections:

    • Thermal electromagnetic over-current and short-circuit protection enhance safe and stable equipment operation.

  • Maintenance Reminders:

    • Actively reminds users when equipment maintenance or vacuum pump lubricating oil replacement is due.

  • Ambient Temperature Monitoring:

    • Automatically triggers an alarm if the ambient temperature exceeds safe limits.

  • Optional Enhancements:

    • Supports an optional eutectic point detection device and endpoint-judgment detection system to make freeze-drying processes more scientific.

 

Drying chamber · The separate drying chamber reduces the probability of damage caused by improper handling of the drying chamber due to height and weight.The upper cover is anodized aluminum with anti-corrosion treatment.

●Highly transparent plexiglass drying chamber,good light and heat radiation conduction.Reserve 6/12 external   valve ports.

· 316L stainless steel all black Teflon coating drying chamber, suitable for drying organic solvents and  various corrosive samples, reserved for 6/12 external ports.

· 316L stainless steel vertical multi-port multi-manifold external rack

(The standard configuration is aplexiglass drying chamber, and one ofthe diying chambers can be optional)
Cold trap and

condensing coil

 · The cold trap cavity and condensation coil are made of 316L stainless steel.Large opening and channel design, the gas can be quickly captured through the condensing coil.

· The cavity and condensing coil are equipped with Teflon anti corrosion coating as standard, which can trap organic solvents and various corrosive solvents.

· The condensing coil is placed in the cold trap to increase the condensate catchment area, which can effectively prevent external condensation.
Sample shelves · 316L stainless steel stackable sample shelves, capable of lyophilizing machine solvents and various corrosive  solvents.Each shelf can be placed and taken freely without manual work.The distance and height of each shelf

can be adjusted freely.

-All black coating, good heat absorption performance.

-Special hole for freeze-drying of centrifuge tubes, which is conducive to the drying of samples in centrifuge

tube containers.

· All-aluminum Teflon surface anti-corrosion treatment electric heating shelf.
Refrigeration

system

 · Danffos compressor

Copper plate heat exchanger, the largest area to increase heat dissipation

· Unique refrigeration technology, the temperature of the cold trap can be lowered from ambient temperature

to below-80C°within 2 minutes.

· Class A temperature sensor with high temperature accuracy and low error.

· Multiple detection and alarm system, the refrigeration system pressure is too high or refrigeration failure can timely alarm and take corresponding measures.
