Room Oxygen Monitor and Alarm for Cold Storage Applications

Room oxygen depletion monitor

Room oxygen monitor detects oxygen deficiency in refrigerators and freezers down to -50°C.

Gaslab's RAD-0002-ZR is a fixed, wall-mount low oxygen safety monitor and alarm using a sensor capable of measuring potentially dangerous oxygen levels in freezers and other cold storage applications.

It is designed to be used in cryogenic facilities, laboratories, food industry freezers, and similar low temperature environments with the ability to monitor oxygen levels down to -50°C (-58°F) in enclosed areas without calibration or maintenance for up to 10 years.

“In creating this device, we gathered critical feedback from some of the largest industries in the market,” said Travis Lenander, CEO at GasLab.

“Our goal was to develop a safety monitor that would exceed even the most rigorous of temperature requirements. The RAD-0002-ZR provides customers with the ability to ensure workplace safety in enclosed spaces while monitoring enclosed areas with up to 99.9% nitrogen in low temperatures,” he added.

Oxygen Depletion Alarm Features

Low temperature oxygen safety alarm

While monitoring oxygen at low temperatures is a new feature, it is not the only change from our current Oxygen Safety Alarm. The new zirconium oxide sensor provides even greater longevity under normal operating conditions. The  new sensor has a 10+ year lifespan.

Like any of our gas safety alarms, the RAD-0002-ZR includes both audible and visual alarm indicators in both the sensor unit and the remote display unit. This ensures staff will be instantly notified before they enter an oxygen deficient area. In the event of a potential hazard, the both an audible and visual alarm will be triggered. In addition, 3 relays and a 4-20mA analog signal can trigger a fire control panel to alert users to evacuate the area.

The RAD-0002-ZR has an easy-to-read LCD screen which displays the current oxygen levels at-a-glance. This gives employees peace of mind with the monitor’s presence and ease of readability.

Having designed the RAD-0002-ZR around customer feedback, this low oxygen monitoring system will not only ensure that employees and customers are protected, but includes 3-user configurable alarms designed to meet OSHA confined space regulations.

For reference, "Confined space" means a space that:

  1. Is large enough and so configured that an employee can bodily enter and perform assigned work; and
  2. Has limited or restricted means for entry or exit (for example, tanks, vessels, silos, storage bins, hoppers, vaults, and pits are spaces that may have limited means of entry.); and
  3. Is not designed for continuous employee occupancy.

Oxygen Depletion Sensor Benefits

The zirconia oxide sensor offers additional benefits as well. Customers now can use a single system when working with storage cylinders of nitrogen, argon, ammonia, chlorine, propane, nitrous oxide, helium, argon, and many other gases. The sensor is an accurate, long-life solution that ensures no false alarms and no cross-sensitivity to low temperatures.

A bonus is the devices easy to use design. Simply mount it on the wall, plug it in and it starts working in seconds.

With continuous monitoring, extensive alarm settings, user configurability, field assurance, and more the RAD-0002-ZR is well suited for applications which before were not easily available in a single, easy to install and use device.

How the Cold Temperature Oxygen Monitor was Designed

“Having a combined 30 years’ experience in this field has allowed our R&D team to identify an opportunity to create a product that provides a solution for almost every low temperature or cryogenic application,” said Ray Hicks, Gaslab CTO.

"At Gaslab, we know that oxygen deprivation is a “silent killer”. By providing top-quality, low oxygen technologies such as the RAD-0002 line, we recognize that we can contribute to this market while protecting numerous lives," he added.

Customer feedback was incredibly prominent in the design of this new and advanced low oxygen monitoring system, said Hicks.

"Working with our customers’ overall needs and requirements has further strengthened our lead within the cryogenic space. Whether the application be cryotherapy, cryostorage, pharmaceutical, food preservation, fabrication, or food and beverage, Gaslab continues to be a highly credible manufacturer providing best-in-class devices, incomparable support, and true customer responsiveness."

“Our continued success is a direct result of our partnerships and customer relations. With the increase use of inert gas applications, we will continue to expand our solutions for partners and customers across the globe,” he added.
