CO2 Equipments


Water scrubbers are specially designed to remove impurities from raw gas. Let it be in Distilleries, Breweries or fertilizer based, the BIG Group designed water scrubbers are designed with complete SS internals and with the latest scrubbing technology so that every molecule of CO2 is washed with water. CIP is the latest edition, where all the scrubbers are equipped with auto CIP procedure.

The water scrubbers either it’s a High Pressure or Low Pressure both are designed to maintain minimum water levels so that there is no loss of CO2 while washing.

CO2 Compressor

BIG Group CO2 Compressors efficiently recovers CO2 from various sources providing food grade CO2 that meets the highest quality standards in the industry. Designed to meet each customer’s specific situation, the state-of-the-art CO2 recovery compressor offers the lowest production costs per liquid CO2 tonne.


  • Food grade CO2
  • High purity: CO2; 99.99%
  • Up to 60% energy reduction
  • Fully automatic operation
  • Compact skid mounted design for quick installation
  • Experienced technical support

Carbon Filters

Activated carbon filter Beds are charged with small pieces of carbon pellets, typically in granular form, that have been treated to be extremely porous. It is so cavernous, in fact, that just one gram of activated carbon can easily have a surface area of 500m2 or higher. Vast surface area enables these carbon filters to adsorb exponentially more contaminants. The more porous the activated carbon is, the more contaminants it will capture. These Beds are most notably used to remove hazardous compounds in CO2.

These beds are fully automated and in-case of distilleries and Breweries these ACF beds are regenerated with steam.


  • Removes Hydrocarbons
  • Removes Sulfur compounds
  • Removes Aldehyde groups
  • Removes Aromatic as Benzene & other VOCs
  • Removes Off Odours

Drier Filter Towers

Drier filter towers consist of molecular sieve. This material consists of pores (very small holes) of uniform size. These pore diameters are similar in size to small molecules, and thus large molecules cannot enter or be adsorbed, while smaller molecules can. As a mixture of molecules migrate through the stationary bed of porous, semi-solid substance referred to as a sieve (or matrix), the components of highest molecular weight (which are unable to pass into the molecular pores) leave the bed first, followed by successively smaller molecules.

BIG Group drier filters are designed to remove complete moisture from the running stream with results up-to 0.1 PPM. The ISBT approved standard for moisture is 20 PPM, but we design our dryers to get consistent stream of 0.1 PPM, which is a great milestone achievement in the industry.


  • Removal of Water and HydroCarbons from Gas
  • Seperation of ISO / NORMAL PARAFFIN
  • Seperation of AIR, OXYGEN, NITROGEN, HYDROGEN and SYNTHESIS Gases from Mixed Gas Streams.

Liquification System

BIG Group screw compressor packages are used in a wide range of industrial refrigeration applications. All of our compressor packages are built to ensure maximum reliability and efficiency, operational safety, trouble-free operation, and easy maintenance.
Screw compressors are also positive displacement cooling system components. As one screw and twin-screw compressors are widely used in refrigeration. One of the screw compressor consists of one screw rotor (shaft)and a pair of gates rotors, which are then grid and together with the form of the case of pressurized volume, which is compressed.

Highlights & Technical features:

  • Service-friendly, compact layout
  • D-flange motor requiring no alignment
  • Multi-stage oil separator design guarantees low oil loss
  • Multiple oil-cooling options: thermosiphon, liquid-injection, water-cooled
  • Discharge hold back eliminating the need for external oil pump on most liquification system
  • High-definition, multi-touch control panel
  • Thanks to advanced engineering design and less component complexity
  • Screw compressor units combine outstanding reliability and easy servicing with high efficiency
  • These features offer excellent savings potential on energy, service and other operating expenses and lower the total cost of the refrigeration system over its entire life cycle

In addition, BIG Group screw compressors can be provided with other refrigeration system components such as evaporators, condensers, and pressure vessels in a factory-assembled, pre-piped and pre-wired package.


NOX tower consists of special designed grade of molecular sieves. The same adsorbs molecular with a kinetic diameter of less than 9 Angstroms and exclude the larger ones, which is exclusively suitable for the removal of NoX compounds in Liquid Carbon Dioxide.
