Refrigerant Gas R503
Refrigerant R503 meets the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) safety Grade A1, but because R503 is a non-environmentally friendly azeotrope containing CFCS that damage the ozone layer, Therefore, at present, most countries in the world prohibit or restrict the use of R503 refrigerant for the initial installation of new refrigeration equipment (ultra-low temperature, cryogenic) and the re-addition of after-sales equipment maintenance process.
STORAGE & SHIPPING
R503 Refrigerant steel cylinder is a pressurized container. It should be kept away from fire, heat and direct exposure to sunlight. It is usually stored in a cool, dry and ventilated warehouse. When handling, light loading and unloading should be carried out to prevent cylinder and valve and other accessories from damage.
As a widely used ultra-low temperature refrigerant, R503 is mainly used in ultra-low temperature refrigerators or freezers, blood bank refrigerators, freeze-drying machines/freeze-drying machines, environmental test boxes/equipment (hot and cold impact testing machine), biochemical test boxes and other cryogenic equipment (including scientific research refrigeration, medical refrigeration, etc.), most commonly used in the low temperature segment of these overlapping refrigeration systems.
