Improved Comfort and Efficiency

The YORK® Under-sill Concealed Active Chilled Beam is the air distribution device of choice in high-performing, energy-efficient buildings. Specially designed for under-sill induction unit and fan coil retrofit projects, these systems reduce energy costs by using chilled water to transfer heat and greatly reduce air that is moved throughout the building. When compared to conventional VAV systems, the superior performance of active beams can reduce energy use by 30%.
Improved Comfort and Efficiency


Reduced Up-Front Costs

Compact, efficient design reduces material costs per floor and HVAC equipment costs.

Lower Maintenance Costs

Dry coil operation eliminates regular cleaning and disinfecting of condensate pans.

Economical Retrofits

Most, if not all, of the existing piping and duct work can be used.


  • Maximized airflow for optimal energy efficiency
  • Specialized design complements modern architectural styling and minimizes installed space
  • Quiet operation and minimized overall sound
  • Optional MPT coil connections, braided stainless steel flexible hoses, coil drain and external insulation
