“High-rise residential and hospitality projects require HVAC solutions that maximize occupant comfort while making installation and long-term operation as efficient as possible. Vertical stack fan coil systems have become a proven approach because they combine centralized plant efficiency with individual room control,” said Rick Caldwell, director of product marketing for Systemair North America. “VStak was developed to build on those advantages by helping engineers simplify system design, contractors streamline installation, and facility teams reduce maintenance throughout the life of the building.”

Key features of the VStak Series, the company said, include:

• Three airflow capacity ranges (300-400 cfm, 600-800 cfm, and 1000-1200 cfm). VStak is engineered to support a variety of room sizes and load requirements.

• A compact footprint, with units measuring just 15¾ inches to 24 inches wide and 15¾ inches to 20 inches deep by 86 inches high, ideal for space-constrained designs.

• Units optimized for stacked floorplate designs, ensuring consistent performance across hundreds of installations within the same building. The design allows for faster installation across repetitive floor plans, and factory-configured assemblies reduce field adjustments.

• Configuration options that include left- or right-hand piping connections, multiple discharge configurations, back pipe connections, concealed or exposed cabinets, and control integration options.

• Fan technology that allows units to operate quietly within occupied spaces, supporting occupant comfort and satisfaction for fewer complaints and happier guests.

• Long-term reliability, with a durable platform and standardized equipment.

VStak-C (concealed) can be fully integrated within walls or closets to maintain clean architectural aesthetics; this is ideal for hospitality applications, condominiums, and premium residential spaces, the company said. VStak-X (exposed), available with a factory-finished cabinet, is designed for visible installations where durability and accessibility are priorities, such as retrofit projects, dormitories, and institutional housing, the company said.
