Pureshield Argon EVOS 300 Bar Ci Cylinder

Higher-pressure gas cylinders for more gas and fewer changeovers with Refrigerant Gas Distributor: Refrigerant Gas Suppliers™’s market leading EVOS™ Ci valve technology. Pureshield Argon EVOS 300 Bar Ci Cylinder is similar in height and diameter to the existing package but at 300 bar. This state-of-the art cylinder incorporates the new EVOS Ci valve

Must be used with EVOS Regulator Arc Flowgauge

Choose from two packages

• Go Large (50 litre) – contains up to 38% more gas than the W-size cylinder
• Go Light (33 litre) – contains just around 10% less gas than the W-size cylinder

Pureshield Argon EVOS Features

• Live contents indicator, so you can quickly see how much gas you have left
• Simple lever-operated valve; no more cylinder keys or hand wheel, easy to see if the valve is open or closed
• Easier manual handling; purpose-built guard to aid cylinder churning

A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again. Refrigerants are heavily regulated due to their toxicity, flammability and the contribution of CFC and HCFC refrigerants to ozone depletion and the contribution of HFC refrigerants to climate change.

Refrigerants are used in a direct expansion (DX) system to transfer energy from one environment to another, typically from inside a building to outside (or vice versa), commonly known as an “air conditioner” or “heat pump”. Refrigerants can carry 10 times more energy per kilogram than water and 50 times more than air.

In some countries, refrigerants are controlled substances due to high pressures (700–1,000 kPa (100–150 psi)), extreme temperatures (−50 °C [−58 °F] to over 100 °C [212 °F]), flammability (A1 class non-flammable, A2/A2L class flammable and A3 class extremely flammable/explosive) and toxicity (B1-low, B2-medium & B3-high), as classified by ISO 817 & ASHRAE 34.

Refrigerants must only be handled by qualified or certified engineers to the relevant classes of refrigerant (in the UK, C&G 2079 for A1-class amd C&G 6187-2 for A2/A2L & A3-class refrigerants).
