AIRSWIM +

Dehumidifier

The AIRSWIM+ is a double flow dehumidification unit with Fresh Air and Thermodynamic modulation.

The AIRSWIM+ dehumidification is ensured by the action of the heat pump’s refrigeration cycle combined with fresh air modulation with enthalpy recovery.

Performance (according to EN 14511 standard)

Flow range: 10,000 – 60,000 m3/h

Cooling capacity range: from 25 to 125 kW

Description

Manufactured using an all-aluminium structure (frame and casing) for particularly effective corrosion resistance, this dehumidification system comes with a 20-year anti-corrosion warranty (frame- casing).

This dehumidifier comes with a 5-year basic warranty and all ETT services : Commissioning, Audits, Service contracts etc.

Products top benefits

  • Dehumidification achieved by thermodynamic cooling coupled with fresh air modulation
  • Easy installation: multi-block or split delivery available
  • Decarbonisation: new R513A fluid & high-performance energy recovery unit (efficiency > 68%)

Product options

Frame - Casing

  • Motorised external supply air damper (CH 38 – Directive 2006/42/EC), mandatory for machines with a supply air flow rate greater than 10,000m3/h.
  • Triblock machine
  • The machine can be built as a SPLIT with a remote technical compartment and reassembled on site by ETT Services.
  • Tailor-made airflow configuration (supply/fresh air, return/exhaust)

Acoustics

  • STOPFLAM foam sound insulation for the technical compartment
  • Acoustic insulation for fresh air cowl
  • Compressors acoustic jackets

Air handling

  • High-efficiency plug fans with H2S protective coating
  • Pressure gauge for reading air filter pressure drops
  • Filter Fouling Analogue Control (FFAC)
  • Actuating smoke detector with battery back-up, mandatory for machines with a supply air flow rate greater than 10,000m3/h.
  • ISO ePM10 50% (M5), ISO ePM1 50% (F7) or ISO ePM1 80% (F9) opacimetric filters, th. 98 mm available for supply or return air
  • ISO ePM1 80% (F9) polydihedral opacimetric filters in polypropylene th. 292 mm on supply air only

Thermodynamics

  • HP and LP pressure gauges
  • Electronic expansion valves

Opti-dry

  • This system allows enthalpy recovery on the evaporator in the thermodynamic section. The air passes through a cold water coil, that provides free sensible cooling. The thermodynamic evaporator therefore only processes the latent heat (dehu). The hot water coil raises the temperature for free.
  •  Optimisation of the size of the compressor installed.
  • The machine’s total dehumidification capacity is unchanged from the basic configuration.
  • Significant reduction in overall energy consumption.
  • Reduction of installed electrical power (power supply cable for low voltage main distribution board, etc.)

Thermal heat exchangers

  • 3-stage electric coil
  • Triac
  • Hot water coil with analogue frost protection thermostat
  • Modulating 3-way valve mounted on hot water coil
  • Chilled water coil with analogue frost protection thermostat
  • Modulating 3-way valve mounted on chilled water coil
  • Pre-assembled shut-off valve + balancing valve

Installation

  • 200, 400 or 600mm aluminium feet

Electrics and communication

  • Machine Global Energy Meter
  • Phase checker
  • Fresh air humidity sensor with water weight comparison
  • Software licence for BacNet IP protocol
  • IT earthing system compatibility
  • ETT Control Box remote touch display
  • myETTvision remote communication platform

Recovery

  • 316 L stainless steel insulated water-cooled condenser with 3-way valve and automatic reset water flow controller
  • PVC-C shut-off valve on water-cooled condenser (for chlorine water treatment only)

Options for machines installed by the seaside

  • Heresite protection on enthalpy recovery coils
  • Heresite protection on hot water coil
  • Thermodynamic coils with heresite coating
