Honeywell 2138 Pneumatic Humidity Controller, Number of Pipes: 2, Action: Reverse

PNEUMATIC HUMIDISTAT 2 PIPE RA 65-9

Increase comfort levels in industrial and commercial applications with this 2-pipe RA-65-9 Pneumatic Humidistat from Honeywell. This unit weighs less than 20 lbs. and has a dewpoint setting of 40° F and a relative humidity range of 35%-95%. It features an air filter that removes 95% of oil, prevents particle entry and provides for long term corrosion protection, making it ideal for facilities that have indoor air quality problems or require long-term maintenance free use. With an infinite setting of 65%, the humidity control can also be used with most cooling systems.

Pneumatic humidistat with 2 pipping, for a simple and effective control of the air humidity in dry and well ventilated places.

Our humidity control easily installs on existing lines without cutting, tapping, or soldering. The 2138 is an adjustable flow pneumatic humidistat that controls air volume flow from a low side to a high side. It requires no external air, electrical power or external sensing devices. The 2138 comes with a stainless steel lever actuator and sixty foot wiring kits and 4-inch dial face.

This Honeywell pneumatic humidity control is used to maintain the desired level of relative humidity in an area through the use of an electrically operated system. These systems are designed to maintain a constant, preset level of humidity and can prevent condensation and promote a more comfortable interior environment.

A pneumatic humidity controller maintains relative humidity in air-circulating equipment by sensing and controlling the moisture content of the air. It does this by either adding or removing moisture from the air stream using a built-in moisture source, such as a desiccant wheel, finned tube or water spray.

The Honeywell 2138 is a pneumatic humidity controller used to maintain desired relative humidity levels in commercial and industrial buildings. The Honeywell 2138 maintains desired relative humidity output with a digital humidity sensor. This module gives control over supply air temperature and the building's exhaust air pressure. The controller will activate the high side of the terminal device to start the flow of chilled water when within 1% deviation from the setpoint.

The 2138 is an accurate and versatile temperature-compensated humidity controller that provides long term control for a variety of pneumatic humidity control devices. The 2138 combines an accurate pneumatic sensor, inlet air filter and an adjustable setpoint to provide a compact yet highly accurate and programmable humidity controller.
