Subzero therapy uses pressurized CO2 to target very specific areas such as joints, including the hock, stifle, pastern and fetlock, resulting in optimized range of motion and reduced pain.

  • Initial results visible within just 60 seconds
  • Infrared temperature and distance sensors for real-time control
  • Rapid attachment systems for faster setup and storage
  • Long-lasting battery and 15’ polyurethane-shielded cord
  • Backlit, interactive LCD screen shows treatment data
  • Treatment protocols for different conditions

Vets, trainers and physiotherapists report rapid pain relief and overall faster recovery from equine injuries through targeted cold therapy.

This versatile and easy-to-use device treats numerous regions of the sports horse’s body for effective maintenance and injury prevention.


Device with 4 spray nozzles, dome, black cone, extra tank connector, tank cover, briefcase and sleeve.

Shipping:Free shipping within the US. Shipping may take up to 2 weeks.

I’ve never seen results so quickly!

How it Works

The diffuser streams high-pressure, carbon dioxide (CO2) gas at 70 bars pressure and -110°F to the affected site on the horse’s body. This creates a thermal shock that immediately activates the sensory neuroreceptors under the skin. The horse’s central nervous system responds with a corrective reflex, which brings a reduction in inflammation, swelling and pain, with further muscular relaxation, within just 60 seconds.

4 Principle Effects

Equine Cryotherapy is astonishingly effective within a short timeframe and allows you to bring the following benefits to all areas of the horse’s body.

Analgesia: Treatment brings an immediate reduction in pain caused by joint, ligament and tendon issues, allowing horses to recover from acute and chronic lameness faster.

Anti-Inflammatory:Swelling decreases rapidly, while associated increases in blood flow enables faster healing of damaged soft tissue, especially with laminitic horses.

Muscular: Rapid resolution of post-exercise tension and pain from microtears reduces the risk of further tissue damage.

Cardiovascular: Blood vessels dilate leading to improve circulation, minimizing the possibility of further damage caused by poor blood flow to injury sites.

This is the best value for money on the market, bar none. It can easily compete with the most expensive devices out there.
