Product Introduction

The medium shell increases clean-steam output to 120 lb/h through a larger plant-steam heat exchanger and atmospheric vessel. It serves pharmaceutical and healthcare air systems whose demand exceeds a small local generator.

Key Features

Medium duct capacity

The enlarged vessel provides clean-steam mass flow for a sizeable AHU or several distribution tubes.

Indirect plant-steam use

Heat crosses the exchanger wall while boiler steam remains separated from the generated vapor.

Managed atmospheric vessel

Level and drain controls maintain the clean-water boiling space during variable demand.

Technical Parameters

Maximum Output	120 lb/h class
Maximum Operating Pressure	15 psi

Application	Medium AHU humidification
Customization	Heat input, water controls and dispersion arrangement can be configured for the intended application and operating environment.

Applications

Medium pharmaceutical AHUs, healthcare departments, clean manufacturing ventilation and controlled process-air humidification.

Solutions for Your Application

The 35 lb/h generator cannot meet winter design demand in the medium duct.Use the larger 120 lb/h shell and size its plant-steam valve for the actual pressure condition.

Steam may condense before the duct absorbs it.Select a distribution assembly and absorption distance appropriate to airflow, temperature and maximum output.

Available Options

Plant-steam control valve, separator, water treatment, automatic drain, multi-tube dispersion, condensate return and remote monitoring can be selected.
