REARTH VOC Gas Recovery Device Series

Volatile Organic Compound (VOC)Volatile Organic Compounds (organic solvent)

A form of hydrocarbon defined by the WHO (World Health Organization) as a volatile organic compound having a boiling point below 250℃, and that become gas in the air. It is said that there are approximately 200 types of this thinner-like solution solvent in circulation, excluding methane. A common example of this type of solvent is freon, which causes ozone layer depletion and global warming. However, VOC is widely used in production activities that support the lives of people.

REARTH S-series VOC Gas Recovery Device

Product name
REARTH ®Sシリーズ 有機溶剤ガス回収装置

REARTH S-series
VOC gas recovery device

Description

Volatile organic compound gas used for the cleaning and coating of precision parts is compressed and cooled to liquify, and can be recovered. Recycling expensive volatile organic compound discharged in plants and into the atmosphere reduces cost for solvent and responds to environmental issues.

Main Features
  • Achieved more than 99 % elimination efficiency with our own technology, the Compression Cryogenic Condensation Method
  • Responding to wide-ranging solvents and uses, and can also flexibly handle changes in solvent.
  • Wide-ranging experience introducing this device makes installation on diverse discharge equipment possible
  • High solvent removal rate significantly reduces the amount of solvent provide outstanding economic benefits
  • Solvent quality enables reuse and makes it possible to recover
  • Compact design requires little room and alleviates the need for a discharge device

REARTH S-series (Model F) VOC Gas Recovery Device

Product name

REARTH S-series (Model F)
VOC gas recovery device

REARTH ®Sシリーズ F型 有機溶剤ガス回収装置
Description

Upgraded S-series is this “Model F”. Installed our original adsorbent while maintaining the advantages of the S-series. This further heightens recovered solvent quality and enables recovery and reuse of next-generation fluorinated solvent (HFO-type).

Main Features
  • Installing special adsorbent significantly improves recovered solvent quality over the conventional type
  • The new Model F is available to users of the conventional S-series by exchanging the adsorbent unit (F-unit)
  • Able to respond to next-generation fluorinated solvent (HFO). Achieved more than 99 % elimination efficiency with our own technology, the Compression Cryogenic Condensation Method
  • Responding to wide-ranging solvents and uses, and can also flexibly handle changes in solvent
  • Wide-ranging experience introducing this device makes installation on diverse discharge equipment possible
  • High solvent removal rate significantly reduces the amount of solvent provide outstanding economic benefits
  • Solvent quality enables reuse and makes it possible to recover, and the compact design requires little room. A discharge device is not required

VOC gas recovery device

Product name

REARTH CS-series VOC gas recovery device

REARTH ®CSシリーズ 有機溶剤ガス回収装置
Description

The normal pressure, low temperature condensation method CS series device efficiently recovers flammable volatile organic compound gas discharged from various facilities. Corresponding to flammable volatile organic compound gas, enabling response to solvents not possible with S-series.

Main Features
  • Installing special adsorbent significantly improves recovered solvent quality over the conventional type
  • The new Model F is available to users of the conventional S-series by exchanging the adsorbent unit (F-unit)
  • Corresponding to flammable volatile organic compound gas, the device adopted the normal pressure, low temperature condensation method to heighten liquefaction efficiency.
  • Compact design requiring little room for use.
  • Reusing refrigerant exhaust from cryogenic cooler reduces running cost
  • Performing liquified condensation using refrigerator and cooling water results in improved cost performance over the existing type

Simple Recycler Unit

Product name

Simple Recycler Unit

Simple Recycler Unit
Description

Attached equipment exclusively for S-series. Connecting to S-series devices enables recovery of solvent waste liquid discarded during washing and coating processes. Waste liquid is bubbled with low temperature indirect heating, and the vaporized gas is then liquified and collected in recovery device.

Purification Equipment

Product name

Simple Recycler Unit

Purification Equipment
Description

Attached equipment exclusively for S-series. Solvent recovered with the S-series is circulated and filtered through a molecular sieve. This enables the clean removal of solvent residue. High-quality solvent, in particular, required for precision parts manufacturing process can be recovered.
