Anden AS150 High Capacity Steam Humidifier — 1,200 Pints/Day 240VAC 3-Phase with Fan Pack

Commercial-Capacity Steam Humidification for Large Indoor Growing Environments — Anden AS150

The Anden AS150 High Capacity Steam Humidifier delivers up to 1,200 pints of clean steam moisture per day to large indoor cultivation facilities, providing the precise, responsive humidity control that commercial-scale growing operations require to maintain stable VPD targets and protect crop health throughout every growth phase. Electrode steam technology generates pure, mineral-free steam through a disposable cylinder that is replaced rather than cleaned — eliminating the maintenance burden of traditional heating element humidifiers and ensuring consistent steam output over time.

The integrated fan pack, powered directly by the humidifier, distributes steam evenly across the grow environment without requiring ductwork — enabling flexible ductless installation or mounting at canopy height for direct zone humidification. Vapor-logic controls provide reliable humidity management with precise set-point control, supporting the stable environmental conditions that commercial indoor cultivation demands. Operating on 240VAC 3-phase power at 48 amps, the AS150 is backed by a 5-year warranty.

Key Features & Benefits

• 1,200 Pints/Day moisture output — commercial-grade capacity for large indoor grow rooms, multi-bay facilities, and high-volume cultivation environments.
• Electrode steam technology — generates clean, mineral-free steam through electrically heated water rather than heating elements, reducing scale buildup and maintenance.
• Disposable replacement cylinder — cylinder is replaced rather than cleaned when mineral capacity is reached, simplifying maintenance and ensuring consistent steam quality.
• Integrated fan pack — powered by the humidifier for even steam distribution without ductwork, enabling ductless installation or direct canopy-height placement.
• Vapor-logic controls — precise humidity set-point management for consistent environmental conditions throughout all growth stages.
• 240VAC 3-phase / 48A — designed for facilities with 3-phase commercial electrical infrastructure at 240V.
• 5-year warranty — reflects Anden's confidence in the long-term reliability of the AS150 platform.

Who Should Use the Anden AS150 Steam Humidifier

The AS150 is designed for commercial indoor cultivators and large-scale greenhouse operators who require high-capacity steam humidification integrated into a 3-phase 240V electrical infrastructure. It is particularly suited to large single-room or multi-room operations where maintaining precise RH targets across high-volume air spaces is essential to VPD management, disease prevention, and crop quality consistency.

Precision Steam Humidification for Commercial Indoor Cultivation

Humidity management at commercial cultivation scale presents unique challenges — large air volumes, high transpiration loads, and the constant interplay between HVAC systems and environmental conditions all create demands that evaporative or ultrasonic humidifiers cannot reliably meet. Electrode steam humidification responds rapidly to humidity demand, delivers a consistent and measurable moisture output, and maintains set-point accuracy even as ambient conditions fluctuate. For cultivators running VPD-targeted growing programs, the AS150's combination of high output capacity and Vapor-logic control precision makes it the reliable foundation of a well-managed indoor climate system.

Frequently Asked Questions

What is the difference between the AS150, AS150-V2, and AS150-V4?

All three models deliver 1,200 Pints/Day using the same electrode steam platform with Vapor-logic controls. They differ by voltage and amperage: AS150 operates at 240VAC/48A, AS150-V2 at 208VAC/55A, and AS150-V4 at 480VAC/24A. Choose the model that matches your facility's 3-phase electrical supply voltage.

How does electrode steam technology work?

Electrode humidifiers pass electrical current through water between submerged electrodes. The water's natural mineral content provides conductivity that enables the current to flow and heat the water to produce steam. As minerals accumulate in the disposable cylinder over time, the cylinder is simply replaced — no descaling or cleaning required.

Does the AS150 require ductwork to distribute steam?

No. The integrated fan pack distributes steam directly into the grow environment without ductwork, allowing for flexible placement including mounting at canopy height for targeted zone humidification.

How often does the replacement cylinder need to be changed?

Cylinder life depends on water hardness and daily operating hours. Harder water (higher mineral content) reduces cylinder life; softer water extends it. Anden's Vapor-logic controls provide cylinder life monitoring and replacement alerts.

What replacement canister is compatible with the AS150?

The Anden Steam Humidifier Canister (ANDEN5872) is compatible with the AS150 and AS150-V4. Ensure you select the correct canister for your specific model when ordering replacements.
