Hei-VAP B model Industrial Evaporation

Features identical specifications as the Hei-VAP Industrial Safety, but for limited budgets and comes without these safety aspects:

  • Metal frame and safety glass guard hood covering the bath
  • High-impact PMMA door covering the glassware assembly
  • High-impact PMMA latching doors which cover the receiving flask cassettes

With the Hei-VAP Industrial series you are always on the safe side with the safety enclosure protecting you and your glassware! You can operate the Hei-VAP Industrial just by yourself, change flasks in seconds and operate the unit with ease.

The Heidolph large scale evaporators of the Hei-VAP Industrial series are perfectly designed for a great deal of different distilling processes, from standard evaporation without vacuum control up to complex distillation processes with vacuum control.

Aspects such as safety, convenience and cost savings have been considerably taken into account during the development of the large scale evaporators. This is reflected in various unique product advantages.

A temperature sensor powers off the bath in case of any uncontrolled heat-up event. The unique integrated evaporating flask support system allows for one person operation; to remove the flask in just moments.

The automatic water bath refill system along with an additional control panel for filling and electronics allow for use over an extended period of time.

Distill your solvents safely by choosing Heidolph evaporators!

Optional automatic module allow for continuous operation of your solvent distillation process overnight and weekend.

With the Hei-VAP Industrial series you can be sure you are always on the safe side when doing automatic distillation.

Safety features guarantee a smooth distillation process, no matter what solvent you evaporate!

Distilling through automated vacuum distillation allows you to spend a significantly less amount of time on solvent evaporation tasks.

Leading Safety Standards

  • Newly designed EASY LOCK flask attachment allows for safe flask change
  • New Emergency off switch brings the entire unit to a complete stop
  • To promote a safe use of the Hei-VAP Industrial evaporator the interface panel not only has all parameters for operation but also 5 key safety functions that require operator action prior to resuming process
  • Features water level regulation system to prevent water spilling over bath and potentially flooding your lab
  • Safety sensor stops rotation if bath guard hood is opened during operation thus providing user safety
  • A temperature sensor powers off the bath in case of any uncontrolled heat-up
  • To effectively prevent accidents while monitoring parameters the speed, bath temperature and vacuum setting must be confirmed on separate on/off buttons in order to start operation
  • Automatic Safety cut-off in an overpressure situation caused by glassware breakage or defective vacuum circuit
  • Receiving cassette system protects glassware while providing superior flask support. 

Superior Ease of Use 

  • Intuitive touch screen control for ease of operation
  • Touch screen with glass surface for chemical resistance and easy cleaning
  • EASY LOCK flask attachment for quick and easy flask changes
  • Illuminated bath and evaporation flask allows for superior visual control
  • Integrated heating coils guarantee the most convenient and fastest cleaning of the bath
  • Receiver cassettes guard against glassware breakage while providing a self-standing flask support and quick removalof receiving vessels
  • Save time with up to 250 pre-programmed profiles of up to 999 process gradients
  • Unique self-aligning flask support system allows for immediate one-person operation
  • Reduce your process times by using the exclusive AUTOaccurate program which automates your distillation using a vapor temperature system that takes the guesswork out of finding the correct vacuum setting every time
  • No hassle and safety concern due to low fluid levels: self-filling water bath takes the worry out of running dry
  • Receiving flasks feature reinforced bottom drain valves as standard and are protected by cassettes
  • To prevent steam from building up within the guard hood, two strong blowers effectively ventilate the entire area to give you a clear view of the evaporating flask
  • Now you can manage even the most demanding applications easily and eliminate foaming, excessive bubbling or bumping of solutions
  • The automatic process timer turns off your evaporation at a pre-programmed time
  • The optional automatic module Distimatic Industrial allows for continuous and unattended automatic operations
  • Optional Base Cart provides you with a fully-maneuverable rotary evaporator while offering a storage space for vacuum pump, glassware, solvents or accessories
  • Benefit from the LAN and USB interface to save all process data in a digital file

 Reduced Cost of Ownership

  • Universal heating bath for water or other bath fluids allows for temperature settings up to 180 °C
  • Utilize the pre-heating option for your bath and start your application without any loss of time
  • The water bath refill system allows you to step away from your evaporator at any moment and reduce your supervision responsibility to zero for baths that run dry or overheat
  • No hidden cost: all components to control vacuum are included as a standard. This includes vacuum valve, vacuum controller, vacuum sensor and vapor temperature sensor
  • AUTOaccurate-evaporations drive your solution to a variable quantity or dryness, then shut off vacuum, heating bath and rotation, and ventilates the system to give you semi-automated capabilities with significant cost savings
  • Spend your working hours more effectively on other challenges which require your attention and evaporate large quantities continuously with the automatic module Distimatic Industrial
  • Maximize your initial investment significantly: the automatic module Distimatic Industrial is an affordable and more flexible alternative to common 50 or 100-liter evaporators
  • Increased throughput at reduced energy consumption due to an industry leading leakproof vacuum seal:
    • final pressure of 1 mbar
    • pressure increase of 10 mbar/h only
