  • Page 9: Product Overview

    Product overview General notes on the Condair Esco Condair Esco pressurized steam humidifiers are ideal for use wherever existing steam from an on-site compressed steam network is available for humidification. The Condair Esco pressurized humidifier takes the steam from an existing steam network and releases it evenly into the air stream without spraying condensate.

  • Page 10: System Description

    System description Each Condair Esco pressurized steam humidifier consists of the following individual components: – Valve unit (made of ductile cast iron or stainless steel) – Actuator (CA150A-MP electric actuator or pneumatic actuator) – Primary steam trap with a screw connection (cast iron or stainless steel) is connected directly to the valve unit.

  • Page 24: How It Works

    The steam within the system when the ceramic rotary valve is closed is drained via the primary-side steam trap. This means that the Condair Esco is always ready for operation. However, the steam dis- tributor remains cold and does not heat the air flow.

    Components 3.9.1 Valve unit (or also steam connection unit) Steam connection The valve unit is connected to the steam supply line from above using a DIN standard flange or a 1/2" threaded connection on the Esco-5. Strainer (for ductile cast iron valve units only) The strainer is located inside the valve units and it is positioned at a 90 degree angle to the steam supply line.

  • Page 37: Steam Traps

    – The standard steam trap is the "ball float" model because it has proven to work best in practice. Exception: The Condair Esco-5 uses the thermostatic capsule steam trap as standard. 1110513-C EN 2207 Product overview...
  • Page 38 Please follow the following instructions when handling the steam traps: – None of the steam traps used operate below freezing point. They must therefore be protected against frost so that cooled condensate does not freeze. – Inverted bucket steam traps must not be used in systems with superheated steam, since superheated steam removes the condensate resevoir and the inverted bucket can thus blow through (continuous steam discharge at the steam trap).
  • Page 39 How the ball float steam trap works The ball float steam trap is a mechanical trap that works with the buoyancy force of the condensate. If there is air in the steam, the saturated steam temperature is not reached at the corresponding pres- sure and the thermal bleed element (1) opens (see left).
  • Page 40 The thermostatic capsule steam trap is open at temperatures below the saturated steam temperature and therefore also at ambient temperature. Thermostatic capsule steam traps used in Condair Esco open when the condensate cools down (relative to the saturated steam temperature): –...

  • Page 49 DR73 J2A from 1000 to 2000 kg/h In order to reduce the steam velocity in the collector, at least one steam feed is attached to the side of the J2A models. As a result, the steam flow is divided, which reduces the steam velocity. The follow- ing feed variants are possible.
  • Page 50 For special cases where the valve unit must be located inside the ventilation unit, e.g. outdoor systems, there is the option for collectors that have the valve connection on the side of the collector. These ver- sions are only possible if there is sufficient space. For more information, contact your Condair partner. DR73, inside, left...
  • Page 51 Dimensioning of the DR73 steam distributor In addition to the required steam output, the air velocity in the duct is an important parameter for dimen- sioning the DR73 steam distributors. The air velocity determines the wall distance from the outermost steam pipes and the permissible steam capacity per metre of steam pipe.

  • Page 56: Planning

    All steam boilers that enable flawless steam extraction from a sufficiently large steam space are suitable. The additional steam extraction for humidification with the Condair Esco must be taken into account. If the steam boiler is too small, water may be carried along with the steam extraction for humidification.

  • Page 57: Steam Types And Requirements

    Esco valve unit. This process is also known as erosion. Abrasion marks on the ceramic disc openings usually indicate steam that is too wet. Saturated steam Saturated steam has a non-evaporated water content of <2 % and is suitable for use with the Condair Esco. Superheated steam If heat is added to the saturated steam, superheated steam is produced.

  • Page 58: Steam Quality

    – Plant steam This steam is not suitable for humidification. There is also high wear on the Condair Esco system due to particles or additives in the steam. The steam lines are usually made of carbon steel or grey cast iron pipes.

  • Page 59: Ventilation Duct/Unit Requirements

    Ventilation duct/unit requirements Ventilation duct/ventilation unit design In principle, the Condair Esco pressurized steam humidifier releases the steam into the duct air without dripping. However, overfeeding the steam generator, a blocked secondary steam trap or the defect of a regulator or control valve is sufficient to supply water or a condensate/steam mixture to the steam distributor.

  • Page 63: Requirement For The Control Of The Actuators

    Requirement for the control of the actuators The requirements listed below for the control of the actuators only serve as a basis. In any case, contact the relevant local regulatory specialists for detailed information. WARNING! Even with external actuators, only use actuators with a return function (e.g. spring return) so that they close automatically when the high limit humidistat / air flow monitor is triggered.

  • Page 64: Pressurized Steam Network

    The responsibility for a correctly created and maintained steam network is the responsibility of the op- erator. Condair does not offer components for steam networks nor does it design steam networks. The design, construction and maintenance of steam networks must be carried out by a steam specialist.
  • Page 65 Steam supply line dimension The steam supply line connected to the Esco valve unit must be dimensioned so that the steam velocity does not exceed 25 m/s. DANGER! System damage and personal injury due to water hammer Excessive steam velocity increases the risk of water hammer. This can cause serious damage to the system or endanger persons.
  • Page 66 Note: If, due to the permissible steam velocity, a larger nominal diameter than the diameter on the flange of the valve unit must be used, the steam supply line must be extended immediately after the flange. Extension Fig. 37: Expansion of the steam supply line Insulation of steam lines To avoid condensation of the steam on the pipe wall, all steam lines within the steam system must be insulated in accordance with the applicable regulations.
  • Page 67 Drainage must be implemented using a drip leg. This must not too narrow. The drip leg must also have the same nominal diameter up to and including a DN100 steam line, be approx. 700 mm long and not protrude into the steam line. Fig.

    Condensate drain Condensate drain line requirements DANGER! Equipment and personal injury due to water and steam hammer Improperly implemented condensate drain lines can cause water and steam hammer during operation. This can lead to serious damage to the system or endanger persons. For this reason: To avoid water and steam hammer during operation, all condensate drain lines must have been correctly installed in accordance with the following specifications.

  • Page 74 Flash steam (post-evaporation) When draining the pipe system with steam traps, flash steam (post-evaporation) can occur at the end of the condensate line, which is characterised by continuously escaping steam. The cause of this flash steam is the adaptation of the condensate to the external pressure and the large gradient between the condensate temperature and the room temperature.

    10. Spring return at actuator Disconnect the supply voltage or the supply pressure from the actuator. The drop in supply pressure must immediately mechanically close via the return spring. Note: If an external actuator without spring return is unexpectedly used, this reset must be ensured by additional components.

  • Page 78: Adjusting The Angle Of Rotation

    6.2.1.2 Adjusting the angle of rotation WARNING! During adjustment of the angle of rotation, the valve unit opens fully and, if steam pressure applies, humidification will start. If this is not desired, the steam supply to the valve unit must be shut off and depressurized.
