NFerno® 6970 Balaclava

St. Paul, Minn. (October 19, 2009) – Ergodyne today announced the introduction of Hot Rox, a new technology designed to help workers stay warm in extreme cold conditions.

The Hot Rox heat exchanger mouthpiece captures heat and vapor in worker exhalations, then warms and humidifies air for return to the body during inhalation. With its 80 percent efficiency rate, the Hot Rox is an effective way to help keep core body temperatures in the safe zone on frigid days. Breathing warm, humidified air also slows dehydration and reduces the risk of hypothermia and overall body stress.

Hot Rox is found in the N-Ferno® model 6970 Extreme Balaclava, which features thick, stretchy fleece for maximum warmth of the neck, head and face. The product is ideal for workers subject to extreme cold temperatures, including those in construction, freight and baggage, drilling and mining, oil and gas refining, iron and steel work, delivery and service, landscaping, cold storage warehousing and material handling.

“Our patented Hot Rox advances the technology found in your standard winter liner, and it makes our N-Ferno Extreme Series a category-leading product,” said Tom Votel, CEO and president of Ergodyne. “The unique Hot Rox safety features protect workers on the job in the harshest of temperatures.”

Key Features:

  • 320g fleece for warmth in extreme conditions
  • Four-way stretch fleece covers neck, ears, face and head
  • Patented Hot Rox Heat Exchanger to warm incoming air
