Gas Dosing System

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
