About this file

This is a product submittal document for the DriSteem RTS Humidifier RX Series, an electric resistive steam humidifier designed for commercial and industrial building environments. The document provides comprehensive technical specifications, dimensions, weights, electrical requirements, and installation guidance for the product line.

The RTS RX Series includes models ranging from 6 lbs/hr to 324 lbs/hr steam capacity across single-stage, two-stage, three-stage, and four-stage configurations. Electrical specifications are provided for multiple voltage options including 120V, 208V, 240V, 277V, 380V, 480V, and 600V in both single-phase and three-phase configurations, with power requirements ranging from 2 kW to 108 kW depending on model selection. All units operate at 50/60 Hz and feature a standard 5kA Short Circuit Current Rating with optional 100kA rating available. The humidifier uses resistive heating elements to boil water into steam, automatically determines drain rates based on water quality, and includes integrated drain water tempering as standard. Indoor and outdoor enclosure options are available, with detailed dimensional specifications provided for both configurations. For space distribution, two Space Distribution Unit (SDU) models are offered: the SDU-I-RX with 30 lbs/hr capacity and the SDU-E-RX with 126 lbs/hr capacity, both with specific rise, spread, and throw distance requirements to prevent condensation on surrounding surfaces depending on ambient relative humidity conditions.

RTS® Humidifier RX Series

ELECTRIC RESISTIVE HUMIDIFIER

From providing comfort humidity to meeting the strictest clean-room requirements, the RTS electric humidifier is designed to meet the humidification demands of any building environment. The RTS humidifier RX series is an electric humidifier that uses resistive heating elements to boil water into steam. While RO/DI water will grant you the best accuracy with the RTS, any water type can be used. Drain rates are automatically determined per the quality of your water, and integrated drain water tempering is standard on every unit.

•All RTS humidifier models operate at 50/60 Hz.
•For wire sizing, the highest leg draw is shown due to current imbalance.
•See Table 70-1 for heaters.
•Maximum amps is determined based on the heaters used by each model. Some voltage/kW combinations show higher amperage values than

what the unit capacity will allow.

• The standard Short Circuit Current Rating (SCCR) for the RTS humidifier is 5kA. A 100kA rating is available as an option.

INSTALLING SPACE DISTRIBUTION UNITS (SDU)

Provide at least 6" (150 mm) clearance on each side of the SDU.

Field wiring is required to connect the SDU fan and airflow proving switch terminals to RTS electrical panel terminals. Refer to the external connections diagram in the package shipped with your unit.

Important: Maximum ambient RH must not exceed 45% for the SDU-I to operate properly.

As steam is discharged from the SDU-E, it quickly cools and turns to a visible fog that is lighter than air. As this fog is carried away from the SDU-E by the airstream, it tends to rise toward the ceiling. If this fog contacts solid surfaces (columns, beams, ceiling, pipes, etc.) before it disappears, it could collect and drip as water. The greater the space relative humidity, the more the fog will rise, throw and spread.

Table 16-1 lists the minimum rise, throw and spread non-wetting distances for SDU-E at 40%, 50% and 60% RH in the space. Surfaces cooler than ambient temperature, or objects located within this minimum dimension, can cause condensation and dripping. To avoid steam impingement on surrounding areas, observe the minimum non-wetting distances in Table 16-1.

The SDU-E contains a blower (120 V, single-phase, 60 Hz) and an airflow proving switch (field-wired to the humidifier electrical panel). A wiring diagram of the SDU-E is included with the unit.

On a call for humidity, the humidifier begins producing steam, and the start relay energizes the SDU-E blower. When the call for humidity is satisfied, the Vapor-logic controller keeps the blower running to disperse residual moisture using a time delay.

Notes:

• Surfaces or objects directly in the path of steam discharge may cause condensation and dripping.

• To avoid steam impingement on surrounding areas, observe the minimum nonwetting dimensions in this table.

• Rise: The minimum nonwetting height above the steam outlet of the SDU-E-RX.

• Spread: The minimum nonwetting width from the steam outlet of the SDU-E-RX. Spread dimensions greater than 3 ft (1 m) may require additional side clearance.

• Throw: The minimum nonwetting horizontal distance from the steam outlet of the SDU-E-RX.
