Engineered for high-rise apartments, office buildings, dormitories, and hotels, OptiLine provides quiet, comfortable, economical heating and cooling in a very slender package.
With the smallest footprint in the industry, OptiLine is the optimal solution when livable space is at a premium. Available in six sizes, 300 through 1200 CFM, OptiLine can handle the most challenging architectural requirements: retrofit applications and new construction alike.
OptiLine has a variable speed motorized impeller with an EC motor that has been optimized to the impeller allowing the fan to run at the lowest possible RPM – typically less than 60% capacity. This achieves a noise criterion (NC) of less than 30 for the space and provides better humidity control for improved indoor air quality and comfort.
Designed to consume the lowest amount of energy possible, OptiLine’s standard factory features reduce energy costs by 30 to 50% when compared to a typical fan coil.
