The WT 20.48 KOBE and WT 20.48 KOBU are Water-Acid Traps designed to protect gas analyzers by effectively separating condensate, acids, and fine particulates from gas streams.

Key Features:

• Continuous Acid Separation: Ideal for emission measurements involving large diesel engines using heavy fuel, these traps continuously remove high quantities of acids, ensuring the integrity of the gas analysis.

• High Flow Rate Capability: Suitable for applications with high gas flow rates, such as engine test benches, accommodating flows up to 10,000 liters of air per hour.

• Integrated Condensate Tank: Equipped with a built-in condensate tank, allowing for continuous discharge of condensate via a peristaltic pump or automatic separator; manual extraction is also possible.

• Versatile Material Options:

  • WT 20.48 KOBE: Constructed from stainless steel (1.4571), offering robust performance in demanding environments.
  • WT 20.48 KOBU: Made from PVDF (polyvinylidene fluoride), providing excellent chemical resistance.

• Exchangeable Cartridge: Features an easily replaceable cartridge, facilitating straightforward maintenance and extended service life.

• Made in Germany: Manufactured to high-quality standards, ensuring reliability and durability.

• Certified Compliance: Conforms to ATEX 2014/34/EU standards, suitable for use in potentially explosive atmospheres.
