Ingenieurdienst Risto, Kiel - Products: Controls – CryoServer - Control system for liquid nitrogen storage

Controls

CryoServer
Control system for the storage in liquid nitrogen

Application
The modular control system CryoServer can realize all technical controls and safety functions, which are necessary for the fully automatic and safe operation of a storage system with liquid nitrogen.

Structure

Features

Integrated or externally adapted room air monitoring with user-guided function control
Control and monitoring of the fill level and pressure of the supply tank
Control of the safety shut-off valve - switch off in case of oxygen deficiency, emergency stop or excessive pressure
Control of a phase separator, optionally with sub cooler function
Control of an central gas bypass systems
Control of manual or semi-automatic filling stations for Dewars or LN2 transport containers
Monitoring of freezer containers with higher-level control of sequential and simultaneous filling via Modbus communication

Description
The CryoServer control system is equipped with a programmable controller that can be expanded with additional functions and control units, depending on the requirements of the cryogenic storage system. The system includes an UPS to bridge short-term power failures. In addition to Ethernet and RS485 communication interfaces, the system features potential-free signalling contacts for forwarding alarms and faults to the building management system.
