Condair ME Evaporative Humidifier & Cooler

Q: What level of humidity control do evaporative humidifiers offer?

Evaporative humidifiers offer ±10%RH humidity control.

Q: Do evaporative humidifiers present a hygiene risk?

The Condair ME incorporates flush and drain cycles to reduce microbial buildup and optional submerged UV that treats the water in the drain tank to kill bacteria. Properly installed and maintained, evaporative humidifiers provide hygienic humidity control, particularly as they offer aerosol-free humidification.

Q: Do I need a stainless-steel wet section in the duct with an evaporative humidifier?

Evaporative humidifiers do not require a stainless-steel wet section, as there should be no physical wetting inside the duct from the humidifier. The humidifier incorporates its own drain and there should be no aerosol released from the humidifier.

Q: How much space is needed in the duct for an evaporative humidifier?

19.7in clearance prior to the evaporative humidifier is needed for access and to allow for consistent laminar airflow across the evaporative media. No absorption distance is needed after the humidifier, as there is no aerosol.

Q: What is the maximum air velocity?

The maximum face velocity without a droplet separator is 11.5ft/s and with a droplet separator is 14.8ft/s.

Innovative Hydraulic Unit

The Condair ME has a patented compact hydraulic unit that can be mounted on the evaporative module inside the AHU or externally on the outside wall. Exterior mounting enables service work to be carried out without AHU downtime. Interior mounting minimizes installation requirements.

The innovative hydraulic unit incorporates a water tank, up to seven pumps and a pump assisted drain. It is delivered fully assembled and has simple push-fit pipe connections, finger release screws and hand tightened pump mounts for easy servicing.

The full hydraulic unit, or any of its individual components, can be removed and exchanged in minutes making the Condair ME ideal for critical applications that require minimal downtime.

Ideal for Direct and Indirect Cooling

The Condair ME is trusted by the world’s leading data center companies to provide low energy cooling across various AHU evaporative cooling strategies. It can be used to boost the cooling capacity of free-air cooling systems, or in combination with heat recovery units to pre-cool incoming fresh air, through humidification and cooling of extract air prior to exhaust.

Low Energy, Pump-Driven Stage Control

Multiple low energy pumps provide up to five-stage control as standard on units up to 9.8ft wide. On units from 9.8-13.8ft wide, up to seven-stage control is available using two hydraulic units. Unlike single pump systems, output adjustments can be made on the control panel without any mechanical alterations to valves.

Multiple pumps also reduce running costs as low outputs can be met with the minimal number of pumps and a respective reduction in energy consumption. With two pumps running the humidifier only consumes 85W, unlike a single pump system that would need up to 500W.

Modular Design

Evaporative modules are available in a range in sizes from 23.6in to 165.4in wide and 24.6in to 157.5in high. Cassettes are delivered flat-packed for easy assembly on site in a 304 stainless steel framework.

Evaporative Module

Custom-sized evaporative cassettes provide efficient, droplet-free humidification and cooling by passing air through water-wetted corrugated media. Evaporative modules are custom built and can range in size from 24 in - 118 in (600 - 3000 mm) wide and 25 in - 118 in (625 - 3000 mm) high.

Finger-Release Screws

Thoughtful design allows for quick access to the hydraulic unit and easy servicing.

Multi-Stage Pump System

Up to five energy-efficient electronic pumps provide precise five-stage output control, with adjustments made directly from the control panel and no mechanical valve changes required.

Touchscreen Control Panel

An intuitive touchscreen control panel simplifies commissioning, operation and servicing, with detailed system diagnostics, USB reporting and BMS connectivity.

Pump-Assisted Drain

The pump-assisted drain empties the system up to five times faster than gravity drainage, improving humidity control while helping remove deposits and reduce servicing requirements.

Drain Tray with Submerged UV

Optional submerged UV treatment helps control microbial growth in the drain tray, continuously treating the water even when the humidifier is not operating.

Frequently Asked Questions

Why would I use an evaporative rather than a steam humidifier?

Evaporative humidifiers are ideal for high-capacity humidification above 88.2 lb/h. As minerals left behind after evaporation are regularly sent to drain, service requirements are considerably less than steam humidification. Evaporative humidifiers are ideal if cooling is needed or where heat can be recovered from another process to pre-heat the air stream prior to the humidifier. This can result in very low energy humidification in comparison to steam humidifiers.
