For the fourth week of our application highlight series, we are cooling down and diving into O2 and NH3 Detection for refrigeration, from food to pharmaceuticals.

Why do you need O2 and NH3 Detection in refrigeration?

NH3 is becoming more and more frequently used in industrial refrigeration due to its low cost, energy efficiency and environmental friendliness. Large ammonia refrigeration systems are used in the food processing industry to provide cooling for storage, freezing and preserving to extend the shelf life of fresh foods. Additional to food storage, these industrial cooling warehouses will store pharmaceuticals, chemicals and other temperature sensitive products. 

As well as Ammonia, liquid Nitrogen is often used as a form of refrigerant, again, in both the food and pharmaceutical industries. It is a great refrigerant due to its low cost, widespread availability and inert properties. Liquid nitrogen will more commonly be used for freezing such as for Cryopreservation and transporting food.

Ammonia is the most common gas to leak in an industrial environment; it is highly toxic, therefore personal protection is extremely important. When liquid nitrogen is exposed to room temperature, it can turn into nitrogen gas and displace oxygen in the atmosphere. This can lead to oxygen depletion and therefore asphyxiation. Implementing a personal monitor that can detect both NH3 and O2 simultaneously is essential in refrigeration industries utilising both of these gases.

Why use the Duo tracer for portable O2 and NH3 detection? 

The Duo tracer is a lightweight device that simultaneously detects the presence of O2 and NH3 in one device, reducing the need for more than one personal detection unit. This makes the workday more comfortable for your team and allows for easier tracking of both gas concerns. 

The Duo tracer is operated via one button, making it easy to use and reducing the need for lengthy training, so you can get back to your workday quicker.

If you are looking for a low cost, high quality alternative to 2 single gas units, the Duo tracer is the perfect fit! Both weighing and costing less than 2 individual single gas units.
