Page 7: Introduction
Bronkhorst® Controlled Evaporator and Mixer (CEM). Intended use The Bronkhorst® CEM is designed for mass flow control of vapours created from liquid and gas, using the media and operating conditions (e.g. temperature, pressure) as specified at ordering time. The equipment is suited for general purpose indoor (dry) applications, like laboratories and machine enclosures. -
Page 8: Product Description
200 °C. To control the liquid and gas supply flows and the CEM temperature, Bronkhorst offers an E-8000 readout and control unit. This module contains a temperature controller for the heat exchanger and provides a user interface to operate the instrumentation. -

Page 11: Installation
However, compliance with the EMC requirements is not possible without the use of proper cables and connector/gland assemblies. Bronkhorst recommends the use of their standard cables. These cables have the right connectors and if loose ends are used, these are marked to help prevent wrong connection. When using other cables, cable wire diameters should be sufficient to carry the supply current, and voltage loss must be kept as low as possible. -
Page 12: System Assembly
Bronkhorst® Caution: when using the CEM without a Bronkhorst® readout and control unit (E-8000), observe the following guidelines: · The heat exchanger is not suitable for constant AC power supply · The heat exchanger should be incorporated in a temperature control circuit ·... -
Page 13: Working Under Vacuum
(bleeding, purging, starting vapour production, stopping vapour production) · If necessary, contact your Bronkhorst representative for more information and assistance Fluid supply The recommendations in this section will help reduce risks of clogging and improve vapour flow stability. 2.5.1 Carrier gas The carrier gas must be clean and dry. -
Page 14: Liquid Vessel Size
Bronkhorst® Gas entrapment by dissolution can be minimized by taking one of the following measures: · Use a container or vessel with a membrane to pressurize the liquid; the membrane separates the gas from the liquid, so it cannot dissolve. -
Page 15: Operation
Bronkhorst® Operation In systems for use with corrosive, reactive or explosive media, purging the fluidic system for at least 30 minutes with a dry, inert gas (like Nitrogen or Argon) is absolutely necessary before use. After use with such media, complete purging is also required before exposing the system to air. -
Page 16: Starting Vapour Production
Bronkhorst® Starting vapour production · To prevent liquid from flowing into the gas flow controller, make sure that the liquid pressure is never higher than the gas pressure · Always make sure to have a gas flow, before feeding the CEM with liquid. Follow the instructions in the exact order as mentioned below: 1. -
Page 17: Purging
Bronkhorst® Purging Purging the fluidic lines of the CEM system is sometimes necessary, to prevent clogging of the tubing and instrumentation or (cross) contamination of process media. Purging the entire fluidic system is advised at the following occasions: · before changing fluid types ·... -
Page 18: Digital Parameters
Bronkhorst® Digital parameters Using an E-8000 CEM control module, the heating element of the CEM can be operated digitally via RS232 or fieldbus. This section describes the parameters that are used to monitor and control the heating element. Consult the E-8000 manual for installation information and a description of the user interface. -
Page 19: Maintenance
Inexpertly servicing instruments can lead to serious personal injury and/or damage to the instrument or the system it is used in. Therefore, servicing must be performed by trained and qualified personnel. Contact your local Bronkhorst representative for information about cleaning and calibration. Bronkhorst has a trained staff available. -
Page 20: Troubleshooting And Service
Bronkhorst® Troubleshooting and service For a correct analysis of the proper operation of an instrument, it is recommended to disconnect the unit from the process line and check it without applying fluid supply pressure. In case the unit is dirty or clogged, this can be ascertained immediately by loosening the fittings and performing a visual inspection. -
