Condair Esco - live steam humidifier


The Condair Esco can deliver up to 1,000kg/hr of pure, dry steam to an air handling system using a building’s existing steam network. It is ideal for use in hospitals, laboratories and manufacturing facilities where there is a ready supply of steam.

The humidifier’s ceramic rotary valve provides linear 0-100% modulation of steam output. It offers very close humidity control and prevents steam leakage and condensation during periods of low demand.

The Condair Esco’s patented steam lance is fitted with tiny inner nozzles that collect only dry steam from the centre of the steam lance. These nozzles ensure that condensation isn’t introduced to the duct and eliminates the need for pre-heating the steam lance.

Other innovative features include an integral particle strainer that is easy to remove and clean, noise reduction mesh that provides quieter operation, dual condensate traps and a tight flanged steam connection unit.

 Operation

Steam enters the Condair Esco from the top via a standard flange connection. It passes through an integral strainer at 90° to the steam inlet to filter particulate matter. The steam then enters the condensation separation chamber where it encounters baffles to slow its speed. The condensation that precipitates out is sent to the primary condensate drain, leaving behind just dry steam.

On demand for humidification, the rotary actuator opens the ceramic rotary disc valve to the required output. As steam passes through the valve it escapes to atmospheric pressure inside a chamber filled with wire mesh. This mesh softens the noise of the escaping steam.

The steam then enters the steam lance where only the driest and hottest steam is taken from the centre of the pipe. Condensation that forms inside the steam lance is sent to drain via the secondary condensate drain.

    •  Ceramic rotary valve

    The Condair Esco’s ceramic rotary disc valve provides 0-100% modulation and does away with the problems associated with vertical stroke valves. Due to the design, the valve is capable of accurately delivering a linear output throughout the entire regulating range.

    When closed, the valve is absolutely steam tight and prevents any steam from penetrating into the steam lance when the unit is switched off. This avoids unwanted condensation from occurring after steam leakage.

     Condensation-free steam

    Dry steam delivery is guaranteed by the tiny nozzles that are located inside the Condair Esco’s steam lance. The steam is taken only from the centre of the lance, where it is at its hottest and driest. As condensation only gathers around the internal walls of the steam lance, these tiny nozzles prevent condensation from being introduced to the duct.

    The condensation that does form inside the lance is safely channelled away by the secondary condensate drain.

    This innovative system eliminates the need to pre-heat the lance with an exterior steam jacket to avoid condensation. Heated steam lances can add up to 4°C to a duct and by removing this element, the Condair Esco saves energy. Also, live steam humidifiers with jacketed steam lances need to reach temperature before steam can be released into the lance. The Condair Esco will start to release condensation-free dry steam on start-up saving time and offering excellent control.
