Environmentally friendly alternatives to ozone depleting/global warming products

CARE range – Hydrocarbons

BOC’s CARE range of hydrocarbon refrigerants include CARE 10 (R-600a), CARE 30, CARE 40 (R-290) CARE 45 (R-1270) and CARE 50. They:

• Offer minimal environmental impact, excellent thermodynamic properties and cost-effective refrigerant performance.
• Are single products or mixtures of hydrocarbons, isobutane, ethane, propylene and propane, which are classified as:
  • Zero ODP (Ozone Depletion Potential)
  • Minimal GWP (Global Warming Potential
• Can be used in most applications including: air-conditioning, domestic fridges (Greenfreeze technology), retail and hospitality drinks cabinets, factories, offices and supermarkets.
• Are available in a range of cylinders to suit all applications, from mini disposable cylinders to 46 kg cylinders. They can also be supplied in bulk.
• Are available in over 20 countries.

Ammonia (R717)

Ammonia has a low boiling point and is favoured because it is a highly energy efficient refrigerant which also has minimal environmental impact. Our R717 refrigerant:

• Is environmentally friendly, being classified as:
  • Zero ODP (Ozone Depletion Potential)
  • Zero GWP (Global Warming Potential)
• Can be used in a wide range of refrigeration applications including: thermal storage systems, HVAC chillers, process cooling and air-conditioning, food processing, supermarkets.
• Is available in a range of cylinders and drum tanks to suit all applications.

R744 - Refrigerant grade CO₂

Used as a refrigerant since 1850, R-744 is now regaining popularity due to its low environmental impact. Our R-744 refrigerant:

• Is environmentally friendly, being classified as:
  • Zero ODP (Ozone Depletion Potential)
  • Minimal (1) GWP (Global Warming Potential)
• Has excellent thermodynamic properties and low energy usage making it suitable for a range of applications: 
  • industrial heat extraction.
  • chilled warehousing.
  • shipping vessels.
  • commercial refrigeration.
  • mobile air conditioning.
• R-744 is often used as a secondary refigerant along with ammonia, opening up new applications where ammonia as a single stage refrigerant would not be applicable.
• Carbon dioxide is often used directly in food freezing and chilling applications, for example as:
  • Dry ice snow to provide optimum ingredient viscosity and handling characteristics in chilled blenders.
  • Dry ice for in-transit refrigeration.
  • A cryogenic liquid as an alternative to liquid nitrogen in food freezing.

Chlorine and fluorine containing refrigerants

HCFC range

These refrigerants, which include R22, R-123, R-401A, R-401B, R-402A, R-402B,  R-409A and R-416A are gradually being phased out because of their negative environmental impact. They are categorised as:

• Low ODP (Ozone Depletion Potential)
• High GWP (Global Warming Potential)

HFC range

These refrigerants, which include R-134a, R-152a, R-404A, R-407C, R-410A, R-507, R-508A/B, R-413A, R-417A, R-422A, R-423A, R-424A are subject to control in some countries because of their negative environmental impact. They are categorised as:

• Zero ODP (Ozone Depletion Potential)
• Lower GWP (Global Warming Potential)

R134a+UV

R-134a+UV is a specialist product that contains a unique and patented ultra-violet (UV) dye that enables fast leak detection with the use of a UV lamp. It decreases the time and cost associated with servicing mobile air conditioning systems.

Cryogenic gases

We supply carbon dioxide and Nitrogen for cryogenic chilling and freezing processes.
