Ostberg Rotary Energy Recovery Products

Ostberg rotary energy recovery rotors and cassettes are known for:

• Welded spoke structure maintains tolerance
• No-maintenance internal bearings
• Low cost for industrial and commercial applications
• Standard sizes to 3.5-meter diameter – larger sizes available
• Standard depth of 100 mm and 200 mm
• Standard flute height of 1.7 – 2.0 mm offers high capacity, low pressure drop
• Available in non-standard sizes
• Complimentary performance software program

Source of High-Capacity Energy Recovery

• Standard 3A molecular sieve for high-capacity, water-selective absorption
• Smooth face for close seal tolerance and minimal leakage
  

Tough Structure

• Oversized shaft and bearings mean long life and maximum rigidity
• Welded, heavy-gauge interior spokes for maximum rigidity at the hub and outer band
• Minimizes operating run out of the rotor
• Heavy-gauge cassette and center post resist flex from operating air pressures
• Rigid cassette structure for low leakage at higher air velocities 
• Maintains seal clearance

Design and Application Flexibility

• 16 standard sizes for a wide spectrum of air volumes
• 16 different cassette configurations from one standard “universal” cassette 
• Maximum design flexibility
• Single and three-phase motors for all sizes 
• The right voltage for the application
• Adjustable purge section on all sizes
