INTRODUCTION

Moduline

units are integral diffuser air terminals. They are

available with various control devices for constant volume

and variable volume heating and cooling applications.

All units consist of a plenum, valve assembly and diffuser. A

typical unit is shown in Fig. 2. The plenum is thermally and

acoustically insulated and contains a distribution baffle to

provide well-distributed flow to the valve assembly. Figure 3

shows a cross section of a typical 37HS unit.

The valve assembly includes the bellows, which is inflated in

proportion to the duct pressure to regulate airflow to the

space. The bellows is constructed of durable polyurethane.

The assembly is connected at either end to

tubing.

The diffuser assembly is available in a 2-slot, one-way or 2-

way blow configuration. A 3-slot director diffuser is available

for use in cooling/heating applications.

The standard diffuser assembly is not removable. Control ac-

cess is made through a ceiling opening (e.g., a removable

ceiling tile) or nearby light fixture. The 37HS Moduline ter-

minal is also available with a removable diffuser for installa-

tion in non-accessible ceilings.
