Controlled Rate Freezer (-180C)

User-friendly operation with enhanced data traceability

• Intuitive touchscreen display allows for easy set-up, operation, and review of a freezing run
• OPC UA (ethernet) serial communication protocol
• Factory-issued certificates
• Six pre-set freezing profiles and space for up to 14 user-defined, “custom” freeze profiles
• Integrated touchscreen UI logs usage and events to support 21 CFR part 11 requirements
• USB data export of .pdf file run logs support 21 CFR part 11
• User security: 3 levels of user accessibility
• “Run last” feature allows the same profile to be run consecutively with the touch of a button
• PC interface software provides remote operation capabilities, run review, and custom profile creation

Real-time run monitoring for sample protection

• Chamber and sample temperatures are monitored by Type T thermocouples, eliminating lag time and providing “real time” responsiveness
• Standard alarms to alert users of thermocouple failures, heater malfunction, high/low temperature limits, temperature tracking, power failure, and completion of run
• Remote alarm contacts
• Optional thermal printer

Reliable temperature performance for high throughput usage

• Dual solenoid valves are designed to balance LN2 injection volume for precise temperature control and accelerated freezing
• Preventative maintenance indicator for LN2 solenoid replacement limits downtime
• Temperature control and uniformity achieved via an air-handling and liquid nitrogen injection ring system
• Compatible with VHP cleaning techniques
• Environmentally friendly insulating foam
• Type 304 stainless steel with exterior powder-coat finish
