Feeders

Culligan automatic feeders are electronic and offer high injection precision combined with extremely reliable operation. Fitted with electromagnets, they allow the feeding rate to be adjusted by varying the frequency.

The range includes constant feed rate models, in which the feeder flow rate remains constant after the initial setting, and self-adjusting models, in which, after the initial setting, the feeding rate is controlled on the basis of variations in flow rate or other pre-set parameters (pH, residual Chlorine, etc.).

Easy Feeder
Constant Feed Rate Feeder

Of simple construction and compact in size, it provides an economical solution to the most common requirement. The body is in corrosion-resistant plastic. It is supplied complete with bracket for vertical mounting. Available in just one model, for low flow rates.

Basic, Prop and Logic Feeder

Basic, Prop and Logic series models feature:

• three different maximum feed rate capabilities for each series
• tough, reliable construction
• aluminium body, with triple anti-corrosion treatment
• parts in contact with the liquids for injection in Polypropylene,Viton and Teflon
• electronic circuit which cuts out the pump in case of minimum level signal
• supplied for horizontal installation, but vertical installation is possible with just a few simple operations
• selector switch for optimising feeding even at minimum flow rates.

These three series have the following special features:

Basic Feeder - Constant feed rate feeder
Works on the basis of a simple on-off command received from the system (electric float-switch, pump, instrument, etc.).

Prop Feeder - Self-adjusting feeder
The feed rate is automatically adjusted on the basis of pulses received from external meters (available as accessories). Operation with on-off control is available on request.

Logic Feeder - Self-adjusting feeder
The feed rate is controlled by a 4/20 mA DC signal received from instruments of various type. Complete with display, keyboard and microprocessor for setting and functional checks. Operation with on-off control is possible.

Control Instruments

The water used in industrial processes requires accurate, prompt control of the fundamental values which define its quality. The main parameters concerned are temperature, pH, conductivity, oxidation-reduction potential (Redox) and residual Chlorine.

For each of these needs, Culligan offers a complete range of measurement instruments to complement its water treatment systems.
