    2. Safety Instructions 2.1 Overview These safety instructions are required by law. They promote workplace safety and accident prevention. According to ANSI Z535.6 the follwowing signal words are used in this document: DANGER indicates a hazardous situation which, if not avoided, will result in death or serious injury.
  • Page 8: Disposal After Dismantling

    Installation, dismantling, servicing and repair Steam injection humidifier parts on which maintenance or repair work is to be done must be disconnected from voltage and the steam supply shut off. Installation of any additional parts is allowed only after written permission from the manufacturer. After repair, operational safety must be checked out by autho- rised personnel.
  • Page 9: Transport

    3. Transport Overview Please note Proceed carefully when transporting the steam injection humidi- fier in order to prevent damage due to stress or careless loadig and unloading. 3.1 Packing Please note Notice the symbols afixed to the box(es). The kind of packing used is dependent upon the type of unit sup- plied.
  • Page 10: Function And Assembly

    4. Function and Assembly The HygroMatik Steam Injection Humidifier comprises 4 basic elements: • Separator • Control valve with or without control operation • Steam Lances • Additional materials There is a stainless steel version Type A and a mixed material version Type C 4.1 Function...
  • Page 11: Strainer

    5. Strainer There should be a strainer installed in the steam supply line directly in front of every separator. Only if this is done there is guarantee that no foreign particles enter the humidifier unit. Valve cone and valve face in both the control valve and steam trap are sensitive to fouling.
  • Page 12: Separator

    Separator The stainless steel separator is the essential component for moisture separation. The separator is available as models „20“ and „40“. The separator size is dependent upon the desired steam output and available steam pressure. 6.1 Function Steam flows through the pipe union (1) into the separator. Steam and condensate are separated by the joint action of the inlet pipe (2) and the spiral-shaped flow system.
  • Page 13: Control Valve And Actuator

    If equipment made by other manufacturers is used, the customer must check the compatibility with the HygroMatik steam injection humidifier. 7.1 Control Valve The control valve regulates the steam quantity by means of the valve lift.
  • Page 14: Actuator

    In order to comply with DIN 32 730*, electrical actuators must feature a fail-safe function so that in the case of power failure the Type Hygromatik E-4111680 control valve is driven to a safe position (fully closed). Pneumatic Actuator Pneumatic Actuators are controlled using compressed air (e.g.
  • Page 15: Start-Up Safety Switch

    8. Start-up safety switch The function of the start-up safety switch is to ensure that no condensate from the steam network invades the air conditioning duct through the steam lances. Electrical Start-up safety switch With an electrical actuator the supply voltage is looped through the start-up safety switch.
  • Page 16: Steam Lances

    9. Steam Lances In the steam lances (1) dry steam is blown out of specially formed nozzles (2). They are designed for low noise steam emission. The nozzles take steam from the driest area in the steam lance centre. In order to prevent accumulated condensate or aerosol droplets from being transported with the steam, the steam lances are provided with a steam lance heating system (3).

    Steam lance piping for multiple steam lances HygroMatik standard supply is for lengths of 118 in (300 mm) und 177 in (450 mm). Distances are approximate and can vary from installation to installation. Piping should be installed for even lance distribution along the duct height.
  • Page 19: Pressure Gauge Station

    Installation of a pressure gauge on the steam injection unit ensures immediate detection of pressure drops or fluctuations. The HygroMatik Pressure gauge station consists of a tubular spring pressure gauge (0-6 bar), a T-junction and a dual nipple. The pressure gauge is temperature resistant up to 392° F (200°...
  • Page 20: Ball Float Steam Trap

    11. Ball Float Steam Trap After separation from the steam inside the separator condensate is drained out through a ball float steam trap. 11.1 Function The discharge valve is controlled by the ball float dependent upon the density of the incoming medium. Starting Position / Air When the unit starts, air present in the system is discharged through the thermostatic air extractor fan.

  • Page 24: Humidification Output

    13. Humidification Output The maximum humidification output [lb/h] of a steam injection unit depends upon the available steam pressure in bar. Maximum humidification output can be more than 1697 lb/h (770 kg/h) (Type A) or 1609 lb/h (730 kg/h) (Type C). Maximum oper- ating pressure is pmax = 4 bar.
  • Page 25 Example: Desired humidification output: 242 lb/h (110 kg/h) Operating pressure, p = 2 bar The length and number of steam lances is determined by the duct dimensions. See Section 9 "Steam Lances". Please note 1 lb = 0.453592 kg 1 kg = 2 lb 3.273962 oz Result: Follow the operating pressure line until the desired humidifica- tion output in kg/h is reached.

    Risk of injuries due to improper installation! Installation of this steam injection humidifier may only be accom- plished by qualified personnel. HygroMatik can accept no responsibility for any damage caused by incorrect installation. Please observe all safety and hazard instructions supplied with the steam injection humidifier.
  • Page 32: Water Hammer Prevention

    Steam extraction points must lie on the upper side of the pipe surface to prevent condensate being dragged from the pipe. The HYGROMATIK steam injection system must have a filter installed in front of the system. This is delivered with the system or is already installed on-site.
  • Page 33: Electrical Installation

    Install a pressure sensor in the ducting and integrate this into the safety chain. The pressure sensor prevents over-humidification of the ducting in the case of a malfunctioning fan. HygroMatik Actuator wiring diagram Circuitry for alternative actuators may be found in the relevant installations documents.
  • Page 34: Separator

    15.4 Separator Separator efficiency may be severely decreased by conden- sate in steam piping! Supply steam fed into the steam humidifier should feature maxi- mum possible dryness. Before making installation ensure that steam piping by design allows for as little condensate as possi- ble (e.g.
  • Page 35: Pneumatic Start-Up Protection

    Actuator and valve installation positioning When pneumatic actuators are implemented Risk of malfunction! Control air for pneumatic actuators must be free from oil and humidity. 15.6 Pneumatic start-up protection Please note Pneumatic start-up protection is set to 205° F/96° C. This value may only be altered by the manufacturer.
  • Page 36: Steam Lances

    Angle pieces for installation of humidifier/valve unit parallel to ducting walls are available from HygroMatik. In order to reduce the absorbtion distance the steam from the lance should be directed opposed to the air direction in the duct- ing.
  • Page 37 In order to prevent steam condensing on the duct inner walls, the steam lances should be installed observing the following dimensional prerequisites: Dimension [in./mm] Model DDS 20 1.5/ 1.2/30 0.8/20-3.1/80 Model DDS 40 2.1/ 1.2/30 0.8/20-3.1/80 *„k“ is the necessary drill diameter in the duct wall A duct wall thickness of 1.2 in/30 mm is assumed.

  • Page 40 Position lances in the duct centre if possible. If the humidifier blows into a compact multi-zone unit, it should be installed directly in the air flow and as close as possible to the fan. The bifurcated pipe should never be installed less than one meter in front of the fan suction side.
  • Page 41: Steam Lance Heating System

    15.9 Steam Lance Heating System Risk of material damage due to excess pressure The heating system feed pipe must allow for pressures of up to 8 bar.
