Energy recovery run-around coils are now an available option for the Vektor C-Series (centrifugal blowers). Up to 3 fans can share a single exhaust plenum with double wall, foam insulated construction.
N+1 and N-1 redundancy can now be achieved with these exhaust systems with airflows up to 40,000 CFM. These systems are pre-designed, pre-engineered and CAPS configurable. This eliminates the need for custom exhaust box requirements for a budget conscious projects.
