Product Features & Benefits Refrigerant grade R744 (CO2) is available from A‑Gas in gas (vapour) or liquid form Non-flammable with a safety classification of A1 Compressors must be charged with modified polyolester oils, contact the compressor manufacturer for more information Excellent R744 is the chemical reference for carbon dioxide (CO 2) used as refrigerant.It is a naturally occurring substance that can be applied as a working fluid in different heating and cooling applications, due to its excellent heat transfer properties and its high volumetric cooling capacity. NatRef Supplier TEGA Acquires Linde’s Austrian Refrigerant Business By Ntsako Khosa , Apr 12, 2021, 14:16 TEGA aims to build a closer collaboration with Austrian customers. The new station therefore conforms to the strictest industry standards governing air conditioning maintenance and recharge systems for the new R744 (CO2) refrigerant. These new systems are intended to minimise pollution and to reduce the risk of fire in the event of leaks, and are radically different in design from previous generations of recharge station that used R134a and R1234yf refrigerants. Features Heat pump water heaters and car air conditioners, are also used as refrigerant in the binary refrigeration cycle of refrigerated showcases. R744.

When using R744 refrigerant, two particular aspects must be considered for reasons of operational safety: The refrigerant circuit must be secured to prevent components from bursting. This protection is provided in the form of a pressure-temperature sensor and pressure limiting valves on the high-pressure and low-pressure sides alike. The refrigerant for busses . Carbon dioxide (R744) is over a thousand times less harmful on the atmosphere than the conventional R134a refrigerant. It has an excellent cooling capacity, it is not flammable and readily available worldwide at low cost. Leading bus manufacturers already launched the first models with R 744 air conditioners.

R744 can be used for a variety of refrigeration needs, such as, air conditioning, commercial refrigeration, Carbon Dioxide – R744. About Carbon Dioxide (CO2) Refrigeration.

Grundfunktioner ROCOOL 600. 1. Öppna batterifacket och sätt i 9V-batteriet. 2. Stäng av ROCOOL 600 R-744 is a natural refrigerant. But, unlike other natural refrigerants, there is not a safety concern. With hydrocarbons you have the flammability risk, with Ammonia you have the toxicity risk, but with CO2 the safety risk is minimal.

R744 is the refrigerant name for carbon dioxide, which will first appear in high-end cars from the big German brands. CO2 requires operating pressures up to ten times higher than R134a. The reason why the use of CO 2, which needs to be reduced, as a refrigerant, is because it is a natural refrigerant with a LOWER GWP than the other refrigerant overwhelmingly. Refrigerant number R744 Liquid carbon dioxide (industry nomenclature R744 or R-744) was used as a refrigerant prior to the discovery of R-12 and may enjoy a renaissance due to the fact that R134a contributes to climate change more than CO 2 does.

Both refrigerants and the systems designed for them will present significant changes to the tools, working practices, component standards and workplace safety considerations relating to repair, service and refrigerant recovery. R744 is refrigerant grade Co2 is 0 ozone depleting, very low GWP and can be used in a wide range of refrigeration and A/C applications. Available in Liquid and Vapour. It must be noted that Co2 systems operate at high pressure and low critical temperature so special guidance must be followed in system design. R744 refrigerant grade carbon dioxide 03 R744 – used in commercial refrigeration such as in supermarkets. Purity and moisture Moisture in R744 based refrigeration and air conditioning systems will create carbonic acid. This acid then causes corrosion in the steel pipe work.

As one of the original refrigerants used nearly 100 years ago, its environmental profile and performance is proving it a considerable alternative. CO 2 has demonstrated favorable results in different system configurations over time. R1234yf and R744 (carbon dioxide) are two refrigerants that have been adopted by some global vehicle manufacturers as alternatives to R134a. Both refrigerants and the systems designed for them will present significant changes to the tools, working practices, component standards and workplace safety considerations relating to repair, service and refrigerant recovery. R744 is refrigerant grade Co2 is 0 ozone depleting, very low GWP and can be used in a wide range of refrigeration and A/C applications.

R-744 Carbon Dioxide is one of the oldest refrigerants in the world. Its first usage can be traced all the way back to the nineteenth century. Before the popularity of CFC and HCFC refrigerants Carbon Dioxide was one of the most widely used refrigerants. R744 är miljövänlig och har varken ozonnedbrytande potential (ODP) eller global uppvärmningspotential (GWP).
