The Need for Precise Humidity Control is Widespread.

Many businesses have valuable inventories and specific processes that require protection. Most businesses rely significantly upon electronics to conduct day-to-day operations and all strive to increase employee productivity. Incorrect humidity levels in the workplace, however, can wreak havoc on certain electronic devices, not to mention your comfort and productivity!

The light commercial solution is steam humidification from Aprilaire.

You need a humidification system that is customizable for your specific applications in mind. You need a humidification system that is affordable and easy to maintain. You need a system that provides the correct amount of moisture for your business needs (whether you sell electronics or cakes). You need a reliable humidification system that provides comfort for you and your customers. You need an Aprilaire steam humidifier from The Lynch Company.

Too much humidity can be as much of a problem as too little humidity. Unlike portable units, Aprilaire Whole-Home or Office Humidifiers continually monitor relative humidity levels, then adjust to deliver the right amount of moisture (scroll down to view the Optimum Relative Humidity Chart) —never too much or too little— to your entire operation. Aprilaire Humidifiers don't require the daily (or at best, weekly) cleaning and disinfecting that many portable units require and you never need to worry about the risk of microbial organism growth due to standing water.

Automatic, friendly controls make it amazingly easy!

Operational Specifications

• Internal Control Board— Manages the complete operation of the humidifier including fill cycles, heater operation, control signal and drain cycles.
• User Interface/Display Panel— Provides power switch for on/off operation, illuminates LEDs to show fill, drain, and steam production operations, and provides codes for service diagnostics.
• Water Level Control Probe— Manages the water level in the steam chamber by monitoring the water level and signaling the internal controller to fill or drain the chamber. Includes a safety shut down system to prevent the steam chamber from overfilling.
• Immersion Heaters— Produce steam through the use of resistive element immersion heaters located in a stainless steel steam chamber.
• Contactor—Controls heaters in modulating units and is rated for increased cycles associated with modulating control.
• Power Relay—Controls heaters in on/off units to reduce the unit noise level.
• Operating Time Monitor— Accumulates actual humidifier run time to activate the automatic drain and flush cycle, end-of-season drain function and the steam chamber cool down period.
• Enable the HVAC equipment fan— Allows the humidifier to produce steam when there is a call/need for humidification and the HVAC system is idle by turning the blower on.
• Rapid Start-Up Function—Turns the humidifier on at 100% output upon a call for humidity to bring the steam chamber to the proper temperature to produce steam. The humidifier will then shut off and restart based on the corresponding humidistat control signal.
• Automatic Drain and Flush Cycle— Drains the steam chamber periodically and flushes it with clean water to prevent mineral deposit build-up in the steam chamber.
• End-of-Season Drain—Drains the steam chamber of water after a 72-hour period in which no calls for humidity take place.
• Cool Down Period— Tempers the water before draining the steam chamber to prevent water hotter than 140ºF from being introduced into the building drain.
• Signal By Others— Accepts an on/off signal, or 1-10 VDC or 4-20mA modulating signal for unit control.
