Operating conditions of cold trap GKF 1000i
➨ The cold trap GKF 1000i is not suitable to condensate
- unstable substances,
- self inflammable substances,
- substances which are inflammable without air and
- explosive substances.
Safety during operation
➨ Adopt suitable measures to prevent the release of dangerous, toxic, explosive,
corrosive, noxious or polluting fluids when draining condensate.
➨ Adopt suitable measures to prevent the formation of explosive or flammable mix-
tures. Oxygen may condensate at the temperature of liquid nitrogen, use inert
gas for venting if necessary.
➨ A great amount of gas can be absorbed on cold surfaces. The gases may expand
abruptly in case of warming. This may lead to inadmissible overpressure in the
system. Risk of bursting!
☞ Check coolant level in the cold trap during operation at appropriate intervals.
Coolant may overflow unexpectedly, e.g., in case of large amounts of gas.
☞ Comply with applicable regulations when disposing of condensates. Take into
consideration that the condensate may be polluted.
Take adequate precautions to protect yourself and other people from the effects
of dangerous substances (inhaling or skin contact). Wear appropriate safety-
clothing and safety glasses.
☞ Use only genuine spare parts and accessories.
Otherwise safety and performance of the equipment might be reduced.
☞ Do not use damaged components.
• Perform a visual check of the cold trap prior to every use. Check the cold trap for
damage: There must be no damage, notches, cracks or scrapers on the glass
surface.
• Comply with all applicable safety measures and requirements when using cryo-
genic coolants.
Use only transport receptacles intended for coolants.
Wear safety glasses and protective gloves.
• Do not clamp the covers of coolant receptacles. Ensure pressure compensation
between coolant receptacle and atmosphere at any time.
Check condensate level regularly and drain condensate in time (condensate drain
valve).
To the best of our knowledge the cold trap GKF 1000i is in compliance with the re-
quirements of the applicable standards and directives.
