Dosing System

Share |

Dosing systems are widely accepted as the most accurate dosing products. Gas dosing systems are one of the important filter testing equipment that are modular in design, simple to use and inexpensive to maintain. These filter testing equipment work on the vacuum principle and come in a variety of sizes and specifications to meet the diverse application needs.

The gas dosing systems are versatile testing equipment that can be manually or vacuum operated and suit to a wide range of applications. These equipment come in the form of a wall, yoke or direct cylinder mounted units and can be wall mounted or mounted directly to a gas container. Available in a variety of dosing ranges, the gas dosing systems can be used for low demand applications as well as large municipal water treatment installations

Features
Simple and easy to operate, the gas dosing systems come with following salient features:

Safe operation, as gas is metered by vacuum principle
Minimum maintenance as the system has only few moving parts Suitable for a range of disinfecting gases, like - Cl2, SO2, NH3
Wide operating capacity
With proven technology, deliver accurate and reliable dosing
Precision control of gas flow using linear area control valve
Corrosion resistant materials ensure durability
No regular supervision required
Modular design makes installation and operation simple and easy

Auxiliary Equipment
The gas dosing systems come complete with a set of auxiliary equipment, such as ejectors and vacuum regulators. A brief description of these auxiliary equipment is given below.

Ejector (Vacuum Drawing Systems): Ejectors are designed to create the vacuum conditions under which the dosing systems operate. The safe and simple function of the ejector eliminates the requirement for dosing pumps and provides a range of dosing chemicals and capacities to be catered for. The ejector is fitted and installed directly into a dedicated motive water line with the choice of a booster pump and draws chemical into the water.

Suitable for a variety of chemicals, such as - Cl2, SO2, NH3, CO2, NaOCI, NaHSO3
Wide operating capacity
Requires minimum maintenance
Safe and easy to operate
Deliver durability and reliability with corrosion resistance materials

Vacuum Regulators
The vacuum regulators function as pressure reducing valves that are used for transferring gas under pressure to gas under vacuum within the dosing arrangement. The equipment operates only when the vacuum is present and is completely safe in the event of vacuum failure. Some of its important features:

Comes in variety of capacities and operates in a wide range
Shuts off the supply of gas in the case of vacuum failure
Fitted with durable parts and components
An auxiliary pressure-reducing valve is not required
Suitable for a variety of gases
With simple and low part count requires minimum maintenance.
