Humidifiers

From providing comfort humidity to meeting the strictest clean-room requirements, the Vapor stream electric humidifier is an industrial-grade unit designed to meet the humidification demands of any building environment.

VLC Features
• Broad capacity ranges from 5.7 to 285 lbs/hr (2.6 to 129 kg/h), link up to 16 units for capacity up to 4560 lbs/hr (2068 kg/h)
• Control ability on/off proportional or SSR (Solid-state relay)
• Electronically monitored water level ensures safe and reliable operation
• Consistent and reliable control to ±1% RH
• Interoperability allows communication with building automation systems via Modbus or with optional BACnet or LonTalk protocols.
• End-of-season auto drain minimizes microbial growth

Easy Maintenance
• Softened water significantly reduces maintenance requirements.
• User-adjustable water skimmer skims off floating minerals
• Controller-operated drain and flush removes precipitated minerals from evaporating chamber
• Cleanout plate and removable cover provide inspection and service access

Additional Options
• 316 stainless steel construction
• Evaporating chamber insulation
• NEMA -4 control cabinet

Vapor stream Components

1. Vapor-Logic 4 Controller: Vapor-logic controls all humidifier functions and can connect to a building automation system via Modbus or optional BACnet or LonTalk.

2.Water Level Control: Tap/Softened water control water leves electronically using a three-rod probe. Systems with the RO/DI water option control water levels using a float valve and low-water cutoff switch.

3. Drainage: Duration and frequency of draining are user adjustable. To avoid possible stagnant water and microbial growth, the humidifier automatically drains if there is no call for humidity after a user-defined time (72-hour default).

4. Water skimmer/overflow port: In tap/softened water systems, the water skimmer reduces surface minerals in the evaporating chamber. Skimming occurs each time the humidifier fills. The skim time duration is user adjustable. In systems with the RO/DI water option, skimming is not required; the skimmer port functions as an overflow port.

5. Heating elements: Low-watt-density Incoloy-sheathed heating elements ensure operation for many seasons. Constant expansion and contraction of heating elements shed mineral scale. In the unlikely event of heater failure, heating elements can be removed easily.

6. Terminal strip: All control wiring connections at the humidifier can be made in this single location.

7. Temperature sensor: Mounted on the evaporating chamber, this sensor enables Over-temperature protection, freeze protection, preheating, allowing rapid response to a call for humidity.

8.Over temperature thermostat: This safety device shuts down the humidifier if it becomes too hot. This is one of three levels of safety protection that also includes the temperature sensor and the water level control system.

9.Service access: Access cover allows periodic inspection and servicing of the evaporating chamber

10. Steam Outlet: Steam generated in the humidifier rises through the steam outlet and travels to the dispersion assembly through vapor hose or piping.
