MV

Description

L.J. Wing's multi-stage face and bypass coils provide greater temperature control flexibility and offer more reliable VAV operation. Greater freeze protection and ease of installation than any other coil available is an added benefit of the new MV-series coils.

The multiple headers, controlled by slow acting on/off valves, provide close control of steam or hot water volume in the coils, allowing better control in VAV (variable air volume) systems. With increased damper control the MV-series coils also minimize temperature stratification and freezestat trips in mild weather.

Variable air volume with little temperature override, uniform air temperature, and maximum freeze protection make L.J. Wing MV-series coils an ideal component for any air handling system.

Features

  • Heavy-duty steam or hot water inlet manifolds with separate valves selectively activate circuits depending upon the required air temperature.
  • Direct-coupled, face-mounted actuator reduces coil casing size by up to 35%, depending upon coil size.
  • Structural framework and connecting flanges both up and downstream make connection to roof, wall, or duct work simple.
  • Integrated dampers maintain constant air volume and pressure drop.
  • Maximum freeze protection with the lowest temperature override.
  • Minimum stratification
  • Performance certified to ARI standard 410
  • ETL listed to UL standard 1995
  • Hydrostatically tested to 500 psig.

How It Works

For 0° Entering Air

Both coil circuits are fully active and the clamshell
damper blades are completely open to allow maximum
temperature rise. The face mounted blade actuator is
responding to a discharge temperature sensor.

How It Works

For +20° Entering Air

Both coil circuits are fully active and the clamshell
damper blades are slowly closing to modulate
temperature rise. The face mounted blade actuator is
responding to a discharge temperature sensor.

How It Works

For +55° Entering Air

The second coil circuit is no longer active and the
clamshell damper blades are modulating to control
temperature rise from the first circuit only. The face
mounted blade actuator is responding to a discharge
temperature sensor.

How It Works

For +70° Entering Air

Both coil circuits are no longer active and the clamshell
damper blades are fully closed to allow complete bypass
air flow with no temperature override.
