Humidity Source has a variety of accessories to supplement our humidifiers and custom designed humidification systems. Wall and duct mounted humidistats, air duct pressure switches and water treatment systems are but a few accessories available from Humidity Source. Our humidistats include human hair and thin film elements, the latter recommended for applications where very high controlled humidity environments of 60% and above are required. Water treatment systems include filters, demineralizers, and Reverse Osmosis units. Water treatment is highly recommended for our centrifugal atomizer humidifiers to reduce salt and mineral build up in the unit which reduces efficiency and for the nozzle systems if water contaminants are a problem.

Your local sales representative or a Humidity Source application engineer can recommend what accessories may be necessary for your HVAC application.

P-825 Wall Mounted Humidistat
Line voltage, on/off, wall mounted Humidstat with human hair element. The best sensing element available at a low cost and a good selection for most applications. Humidstats with electronic sensors should be used for applications where the required R.H. is above 60%.

W351 Electronic Humidistat
With a polymer sensor for high humidity, high sensitivity applications. The W351 features fast response time and close tolerance (+/- 2%). Available in on/off or proportional control, wall or duct mounted, and with optional digital display. The digital display shows both the RH set point and the actual RH at the sensor. The sensor may be remote from controller and display.

Lite-C Digital Humidistat
The Lite-C is a sensitive electronic humidistat with plug-in connections and built-in digital display which eliminates wiring between components. Plug the humidistat into the wall, and plug the humidifier into the humidistat. The installation will be complete.

DCT-927 Drain Tempering Kit
The DTC-927 drain tempering kit is designed to reduce steam humidifier drain water temperatures to less than 140 Deg. F. for safe draining and to meet plumbing codes. A liquid filled bulb-type temperature sensor will automatically open the cold water supply valve and mix cold water with the hot and discharge it at a temperature of 140 Deg. F or less.  

PC-301 Air Flow Switch
Line voltage, on/off, duct mounted, pressure operated air flow proving switch. Prevents operation of the humidifier if there is no air flow in duct.

HC-201 High Limit
Line voltage, on/off, duct mounted, high limit humidistat. Prevents operation of humidifier if R.H. in duct exceeds pre-set limit. Eliminates over-steaming and condensation in duct work until conditions re-stabilize.

Multi-Steam (MS) Distribution System
MS is a special distribution grid system which is used in critical air handling system locations where absorption distances are short or where low air duct temperatures are present. MS consists of a number of vertical stainless steel steam dispersion tubes connected to a horizontal stainless steel manifold which can be custom built for any size duct. The vertical distributors span the total duct height for a more efficient diffusion of steam into the air stream.

Reverse Osmosis Water Systems
Reverse Osmosis (RO) uses advanced semi-permeable membrane technology to remove and reject impurities in the water far beyond the capabilities of normal filtration. Unlike ordinary filters, Reverse Osmosis removes DISSOLVED minerals and creates water equal in quality to DISTILLED water.
