A Pressure Tank 20G (80 Liter) Steel for RO (Reverse Osmosis) systems is a specific type of pressure tank designed for use in RO water filtration systems.
 
Here’s what this designation typically implies:
1. Capacity: The tank has a capacity of 20 gallons, which is approximately 80 liters. This volume allows it to hold a significant amount of water under pressure.
2. Material: It is constructed from steel, which is chosen for its strength and durability. Steel tanks are capable of withstanding the pressure exerted by water and are resistant to corrosion.
3. Purpose: In an RO system, the pressure tank serves several important functions:
   - Storage: It stores purified water produced by the RO membrane and filters.
   - Pressure Maintenance: It maintains pressure within the RO system, ensuring efficient operation of the filtration process and optimal water flow.
   - Smooth Flow: It helps ensure a consistent flow of treated water to the faucet or dispensing point.
4. Installation: Typically installed alongside the RO membrane and filters, the pressure tank connects to the system via plumbing fittings and valves.
5. Operation: The tank is pressurized with air, creating pressure against the stored water. This pressure allows the RO system to operate effectively and ensures there is a ready supply of purified water available for use.
6. Maintenance: Regular maintenance, such as checking the tank's pressure, ensuring proper connections, and occasionally sanitizing or cleaning the tank, is necessary to maintain water quality and system efficiency.
 
In summary, a Pressure Tank 20G (80 Liter) Steel for an RO system is integral to ensuring the efficient and reliable operation of the RO water filtration process by providing storage and pressure maintenance capabilities for purified water.
