What is the LTAP? LTAP is short for low-temperature actuation probe, and it’s a genius device that shuts down the system when the temperature breaches the set point on the low side. This prevents liquid cryogen from flowing downstream and endangering staff and risking equipment failure. Because the LTAP shuts things down instantaneously when the temperature goes a fraction below the set point and before the pressure drops away, it prevents a catastrophic problem before it starts. Completely mechanical, operates even through power outages Generant designed the LTAP to be completely mechanical, so that power outages will not stop it from operating and protecting your system. Since power outages are prime time for something to go wrong with a system, the LTAP continues to operate 24/7, providing peace of mind. Protects lives and equipment If liquid cryogen makes it downstream, there’s a high risk of not only damaging piping and equipment, but also creating a life-threatening environment for staff. For example, if a failure happens overnight and liquid nitrogen is flowing into a facility, the risk of asphyxiation is extremely high when employees enter the facility the next day. Secondary is the concern for damaging pipes and equipment downstream. Many facilities use carbon steel piping, which is more economical than stain- less, but it has a ductile to brittle threshold that could result in a rupture if it becomes too cold. Again, the LTAP prevents this. Tested and proven to be the safest and most reliable The Generant LTAP has undergone hundreds of hours of validation testing, and was designed after exhaustive collaboration between Generant’s engineers and customers out in the field. It is hands- down the best safety device for cryogenic systems. Low Temperature Actuation Probe Series LTAP BULK MICROBULK INSTALLATION Why Every Cryogenic System Needs a LTAP A lot can go wrong, and fast, when a cryogenic system has a problem. Whether it’s abnormally cold temperatures, abnormally high draw rates, or any disruption or failure with equipment downstream, the situation becomes dangerous for personnel and equipment. Recognizing the need for a failsafe safety device, Generant developed the LTAP.
