Hei-VAP Industrial LR20 Distimatic Automatic Module

Overview

The automatic module Hei-VAP Distimatic is compatible with all bench-top and large-scale evaporators from Heidolph

Distimatic Industrial including automatic drainage of residue and adaptor piece for glassware:

• with Glassware set A / A2
• with Glassware set R

Functional principle– For unattended and continuous use - including automatic drainage of residue
Save time by distilling large volumes in a continuous and unattended manner overnight and during the weekend

Automatic solvent supply of the evaporating flask

• Refilling with the Sensor-Mode runs automatically and is based on the desired level in the evaporation flask
• Refilling with the Time-Mode is done according to individual time parameters

Automatic discharge of condensate

• A valve matrix controls the continuous discharge of the condensate from the system into a temporary storage flask. Afterwards the collected condensate will be discharged into the collecting tank by a diaphragm pump

Automatic drainage of residue

• The residue in the evaporating flask will be drained into a collecting tank. Afterwards the process starts again automatically by refilling the evaporating flask

End of distillation process

• The process can be terminated automatically after evaporation is completed or manually at any time by the operator

Programs for Process Control - For distillation select between these two modes:

• Sensor-Mode: Refill and drainage are automatically sensor-controlled
• A sensor detects the fill-level inside the evaporation flask
• The desired/requested fill-level can be set individually
• Flask refill is achieved via valve control and under system pressure
• A sensor monitors the quantity of the solvent mixture and powers off the unit once it is completely processed
• Time-Mode: All parameters controlled by individually pre-programmedautomatic time intervals
• The desired/requested fill-level can be set individually
• Flask refill is achieved via valve control and under system pressure according to pre-programmed cycles
• The process is powered off once the pre-programmed number of cycles have expired

FAQ

What is the maximum viscosity of liquid the Distimatic system can pump?

There isn't a maximum viscosity rating published for the pump, but the pump flow decreases as viscosity increases. You can pump fluids of 1500+ mPa•s viscosity, but it would likely be so slow as to be impractical, especially if it's for anything more than a bit of residue post-evaporation. See the table below for how viscosity affects pump speed on the Distimatic.
