Haldatec provide controllers and timers that are used with sampling or for liquids injection control.

They can be used in stand-alone situations or as backup to other systems.

Signal to pulse converters and timers easily convert a digital or analogue signal to a pulse output to drive solenoid valves for use with sampling and chemical or odourant injection.

Pneumatic timers are for driving pneumatic actuators on samplers or other devices.

Typical uses would be ship loading and off loading and stand alone installations such as pipeline installations where electrical power is either not available or poses complications for hazardous area installations.

Particularly applicable in systems requiring simplicity and reliability.
