Gravimetric Automatic Liquid Dosing Unit

What is the Dermak Gravimetric Automatic Dosing System?

The gravimetric automatic liquid dosing system (DLSys) developed by Dermak PVC enables the automatic and contactless preparation of high-quality formulations, which is crucial for soft PVC production. This system works in tandem with the DDSys powder dosing system to ensure the precise and accurate weighing of liquid stabilizers.

What are Gravimetric and Volumetric Dosing (Pipetting)?

Gravimetric Dosing: This method involves weighing directly on a precision scale. The accuracy is exceptional because it uses a scale, providing a maximum accuracy of 0.1% (one-thousandth).

Volumetric Dosing: This method does not involve weighing with a scale. Instead, it measures the flow through specific volumetric elements such as pipes or syringes over a unit of time. The margin of error is relatively high, ranging from 1% to 3%.

Dermak PVC gravimetric automatic liquid dosing systems are customized based on customer needs and the number of required materials (e.g., DOP, DINP, DIDP). Pre-heating can also be integrated into the system if needed.

Advantages of the System:

• Material savings
• Labor savings
• Time savings
• Energy savings
• Maximum efficiency in production
