Safeguarding Cryogenic Systems with Smart Temperature Protection
WITT’s dome-loaded pressure regulator just got smarter: COLDSTOP SMART now detects critically low temperatures and stops gas flow to safeguard piping. Specifically designed to protect downstream equipment and piping from brittle fractures, this innovative solution establishes a new benchmark for safety, cost efficiency, and remote monitoring in cryogenic systems.
Maximum Protection for Cryogenic Systems
COLDSTOP SMART addresses a critical challenge in cryogenic gas applications: the risk of excessively low temperatures in the gas pipework downstream of the vaporiser, which can cause brittle fractures in mild and carbon steel equipment. Unlike traditional mechanical temperature switches that rely on bi-metallic strips and offer imprecise, unreliable performance, COLDSTOP SMART features integrated technology consisting of the WITT smart dome-loaded pressure regulator, solenoid valves and control unit. This solution stops the gas flow immediately if the temperature falls below a defined setpoint value and restarts as soon as the previously configured setpoint state is reached again. This ensures maximum protection against brittle fractures, enabling companies to meet the relevant EIGA, CGA, and AIGA standards for cryogenic vaporisation systems.
Improved Safety, Cost Efficiency, and Remote Monitoring
COLDSTOP SMART offers several key benefits for users. It enhances safety by providing best-in-class outlet pressure control accuracy and ensures accurate automatic flow stoppage at critical temperature thresholds. This significantly reduces the risk of equipment failure and enhances overall operational safety.
Additionally, it helps reduce costs by preventing damage to expensive equipment and avoiding unplanned shutdowns, which in turn lowers maintenance costs and extends the lifespan of piping and systems.
The smart regulator also supports remote monitoring and custom configuration, transmitting real-time status data - including flow, pressure, and temperature - via 4-20 mA signals and RS485 communication, making it ideal for cryogenic tank telemetry. The system can be custom configured to trigger alarms and initiate corrective actions, such as activating additional vaporiser capacity, providing users with greater control and visibility over their operations.
Compliance with Industry Standards
COLDSTOP SMART not only complies with the EIGA/CGA/AIGA harmonised standards for preventing brittle fraction in cryogenic systems but is also CE-marked.
“Our dome-loaded pressure regulator, already the most accurate and capable of ‘talking’ through real-time data, now takes safety to the next level by knowing when to stop gas flow if temperatures drop too low,” said Andrew Smart, WITT Sales Director for Gas Safety Equipment.
