VRF systems are capable of integrating built up air handlers, such as Trane's USCA, using LEV kit assemblies.

This allows for higher airflows, higher static pressure, larger capacity, customized products, and DOAS configurations.

The kit is available in multiple tonnage sizes.

Using these kits allows installation of an air handling unit to be as far as 541 actual feet (623 equivalent feet) from the condensing unit.

The LEV kit requires three components:

• LEV
• LEV control box
• LEV-kit rated heat pump coil.

If larger capacities are required, the designer may combine multiple LEV kits and condensing units with a single air-handling unit. 

When using LEV kit-equipped air handlers serving a high percentage of outside air, it is best to pair the system with a dedicated VRF heat pump condensing unit. If the outdoor air application requires a VRF heat recovery system, please consult the VRF LEV Kit Split System Selection Guide found in the literature resources below.
