Leimec HeatCycle Ventilation Unit

A compact, energy-efficient air handling system engineered for large-scale industrial ventilation and heat recovery. Installed entirely outdoors—either integrated or hung on suspended from the exterior wall—this unit frees up 100% of internal floor space. It modernizes facility infrastructure, dramatically reduces heating bills by recycling thermal energy from exhaust air, and offers a low-noise, costeffective HVAC upgrade for both retrofits and new builds.

Key Benefits

  • Zero footprint: Wall-hung exterior design saves indoor space
  • External service: Outdoor configuration allows all maintenance from outside
  • Dual filtering: Textile filters clean incoming and outgoing air
  • Smart controls: Operates standalone or integrates with external systems
  • Economic upgrade: Low-cost design for retrofit or new build
  • Easy maintenance: Quick, tool-free dry filter replacement

Technical Highlights & Typical Dimensions

Example configurations illustrate typical industrial HeatCycle ventilation unit footprints. Final sizing, air volume capacity, and duct layouts are always project specific.

  • Rotating heat exchanger: Features a built-in rotating thermal wheel that highly efficiently transfers heat from outgoing exhaust air directly to incoming fresh air.
  • Recirculation upgrades: Can be flexibly equipped with optional secondary HEPA filters to support safe indoor air recirculation when needed.
  • Acoustically optimized fans: Premium radial fans engineered to deliver high-volume throughput while maintaining low noise levels outside the building.
