Pairing VRF with applied HVAC solutions

Learn how Linear Expansion Valve (LEV) Kits help pair VRF with applied HVAC solutions for more flexibility to meet a building’s specific load, airflow, and application requirements.


A variable refrigerant flow (VRF) system is an increasingly popular choice as it provides industry-leading comfort, flexibility, high efficiency, and all-electric heating and cooling. Traditionally, VRF systems can be limited in their type and size of indoor equipment, but by using a Linear Expansion Valve (LEV) or Air Handler Expansion kit, air handler options can be expanded and provide engineers more flexibility to meet a building’s specific load, air flow, and application requirements.

LEV kits enable the advantages of the VRF outdoor system to be paired with applied equipment to get the benefits of inverter technology resulting in higher efficiency. Additionally, LEV kits can provide higher static pressure, larger capacity, customized products, and dedicated outdoor air system configurations.

Register today to better understand what LEV kits are and how to apply them, as well as the control options available.

Learning objectives:

  • Learn what an air handler expansion kit is and how it works.
  • Understand the key applications and building types.
  • Review important design considerations.
  • Understand the importance of proper installation.
