V/VN Series

Vertical Hydronic Unit Heater

The Modine Vertical Hydronic Unit Heaters (V/VN Series) are engineered for applications where conventional horizontal airflow cannot achieve optimal comfort — particularly in buildings with high ceilings, overhead obstructions, or where air delivery must come from above. With vertical discharge, the V/VN series moves warm air directly downward into the occupied zone, ensuring efficient distribution in large-volume environments.

Models

  • V – Copper Tubes (standard temperature/pressure applications)
    • 15 Model Sizes: 42, 59, 78, 95, 139, 161, 193, 212, 247, 279, 333, 385, 500, 610, and 733 MBH
  • VN – Copper-Nickel Tubes (High temperature/pressure applications)
    • 14 Model Sizes: 42, 59, 78, 95, 139, 161, 193, 212, 247, 279, 333, 385, 500, and 610 MBH
Where To Buy

Highlighted Features

Quiet, Clean Hydronic Heating

Powered by hot water or steam, the V/VN delivers smooth, silent heat without fumes or emissions—ideal for enclosed or sensitive environments.

Vertical Heat Delivery

The V/VN’s vertical discharge pushes warm air downward for efficient heating in tall or narrow spaces. It’s perfect for stairwells, entranceways, and mechanical rooms where floor-level comfort is crucial.

Durable, Compact Design

With a heavy-gauge steel cabinet and corrosion-resistant components, the V/VN is built for long-term reliability. Its vertical orientation saves valuable wall space and installs easily in areas where horizontal heaters may not be suitable.

Applications

Vertical delivery unit heaters are ideal for heating buildings with high ceilings or areas that require the heater to be mounted above obstructions, such as craneways.

Common applications include:

  • High-bay warehouses and distribution centers
  • Manufacturing plants with overhead cranes or obstructions
  • Large equipment garages with vehicles or heavy machinery
  • Retail showrooms or atriums with tall ceilings
  • Institutional facilities (gymnasiums, auditoriums, indoor practice facilities)
