Growers who understand the importance of high levels of dissolved oxygen in their irrigation systems produce higher quality products and see increased crop yields.

For cultivators with large oxygen needs or who are operating out of remote locations, maintaining ample oxygen stores can be a challenge. Oxygen tanks can be too costly and delivery can be unavailable to your area.

BioTherm is familiar with these common struggles faced by many greenhouse owners and operators. Our goal is to enhance your irrigation systems and maximize plant growth using cutting-edge technologies, all with efficiency in mind. Our products are proven to increase yields, improve plant vigor, and increase resistance to diseases and pests.

To combat industry pitfalls, BioTherm offers innovative solutions to growers serious about automating their dissolved oxygen supplies.

Enhanced Plant Growth with Dissolved Oxygen

Simply put, dissolved oxygen is the amount of oxygen that is dissolved in water. Just like humans and animals, your plants require an optimal amount of oxygen not only to survive, but to thrive. Because oxygen is a gas and water is a liquid, the mixture of the two elements needs to be done efficiently to ensure the oxygen is dissolved properly.

Why is maintaining proper dissolved oxygen levels in your irrigation water so vital to your plant’s growth quality? The answer is simple, yet fundamental – root health.

Dissolved Oxygen and Plant Root Health

Roots receive the essential elements your plants require to grow and thrive: water, oxygen, and nutrients. When crops do not receive a proper amount of dissolved oxygen, the root system weakens and compromises their ability to absorb nutrients. This put your crops at risk for disease.

Studies have proven that elevating the dissolved oxygen levels in water result in increased root growth. Plants with bigger roots grow faster and healthier, due to increased nutrient consumption and distribution. Increasing the oxygen saturation levels maximizes your crops ability to utilize essential nutrients and defend itself from diseases and pests.

Dissolved Oxygen Systems


The DGS-M™ is an economical and effective means of enhancing dissolved oxygen content in irrigation water and boosting plant health and production. The DGS-M is a high-flow entry-level consumer-based system with expandability options. It can be paired up with the full suite of product offerings such as the O2-Gen for on-demand oxygen, an automation system or simply plug in a K-tank and go.

Now available in a standardized model capable of treating up to 4,000 gallons per day!


For customers with larger oxygen needs, we have the solution. The Oxygen Generation System (OGS) was built to fill the specific need of our Oxygen Infusion customers.

Many greenhouses or grow operations are too remote for delivery of oxygen tanks or require amounts of oxygen that are cost-prohibitive for tank oxygen. Our generator provides 93%+ pure oxygen at pressures high enough for infusion, yet at flow rates low enough for precision control. Other generators or concentrator solutions on the market are unable to achieve this balance.

Built on a strong, but lightweight aluminium frame and field-proven, the OGS unit is a must-have for growers serious about automating their DO experience.


The DOS-X™ Series is an economical and effective means of enhancing dissolved oxygen content in irrigation water and boosting plant health and production.

Now available in standardized models capable of treating up to 15,000 gallons per day!

DO Stat

The DO Stat is our newest product in the Dissolved Oxygen lineup!

Your crop depends on consistency and dissolved oxygen (DO) is a difficult variable to control, but the BioTherm DO Stat works in tandem with the TOOB to optimize DO levels at your setpoint. The DO Stat reads dissolved oxygen and temperature in your greenhouse’s irrigation line or tank and controls the oxygen infusion process.

The touchscreen user interface displays real-time data and allows navigation to adjust settings and alarms. Dissolved Oxygen is indicated in mg/l (ppm) or in the percentage of saturation. The Dissolved Oxygen readings automatically compensate for the temperature effects on the oxygen solubility and membrane permeability.

Available with an Optical or Galvanic sensor.

DO Meter

The DO Meter was developed for measuring dissolved oxygen in the water. This is a rugged, portable dissolved oxygen (DO) meter designed to provide laboratory precision and accuracy under harsh environmental and industrial conditions. Simply drop the sensor into the water to test your current DO levels.
