High humidity

Refrigeration split units with humidity control

Split high temperature refrigeration units and pasive relative humidity control.


IINTARCON High humidity series, are refrigeration split units for high temperatures comprising passive humidity control, specially designed to cover the storage needs of fruits and vegetables conservation, cut flower, wine cellar, fish, etc.

These units consist of a low-noise self-contained condensing unit or a centrifugal condensing unit, and a double flow low-profile evaporating unit, oversized for high humidity applications requiring passive control of relative humidity.

Besides, they include an advanced remote electronic control system to guarantee a certain temperature and a relative humidity among  60%-95%. It is posible to provide the units with humidifying kits and drying-heating kits.

High Humidity systems are available in two configurations:

  • HSF-D series: low-noise self-contained condensing unit designed for outdoors installation (with triple acoustic isolation suitable to work under extreme ambient temperature up to 50ºC) and a double flow low-profile evaporating unit of high relative humidity, from 1,5 to 9,8 kW.
  • HSH-CD series: horizontal centrifugal self-contained condensing unit (for indoors installation, and for ducting outdoors the hot condensation air flow) and a double flow low-profile evaporating unit of high relative humidity, from 1,3 to 9,7 kW.
