EvaPack™ Recirculated Water (RW) Series Configuration and Components

EvaPack™ Recirculated Water (RW) Series Configuration and Components

    • Options for RW Configuration   

      • High efficiency integral droplet separator in PP material (requested for VDI 6022 hygienic configuration)
      • Filling water pretreatment by U.V. lamp with 50μm and 5μm water filters
      • Water high temperature alarm
      • Air relative humidity sensor
      • Air temperature sensor
      • Multiple stage control with solenoid valves (up to 4 stage control)
      • Water conductivity sensor
    • Standard Components Supplied With EvaPack™   

      Note: The EvaPack™ control panel is required for all electrical devices.

      • Water basin with draining and overflow piping
      • Evaporative cassettes (composed of EvaPack™ evaporative pad and cassette frames in stainless steel AISI 304)
      • Side and top frames in stainless AISI 304
      • Irrigation piping
      • Dispersion manifold(s)
      • Water pump
      • Manual adjustment gate valve(s)
      • Water draining valve
      • Solenoid water filling valve
      • Water level sensor
    • Operation Sequences   

      This configuration is recommended when the available supplied water has low or medium hardness.

      (For additional information, please consult the EvaPack ™ Series Evaporative Pad Adiabatic Humidifiers Installation and Operation Manual.)

      • A. Water enters the basin, passing through the filling valve (1). The water level detector (7) controls the basin (2) filling, the pump (3) starting-up and the fill valve opening.
      • B. The recirculation water pump (3) supplies water to the different dispersion manifolds (5). The water flow of each cassette (6) is adjusted with a manual gate valve (4). Calibrated orifices deliver water evenly over each media pad (6).
      • C. Dry air passes through a corrugated bank of wetted cells media (6). Air is cooled and humidified.
      • D. Excess water washes the evaporative pad, then falls (with minerals) into the water tank.
      • E. Excess minerals are drained by the draining valve, minimizing water consumption and media scaling.
