The Model GT5.Ex is a process-analytic cooler designed for the safe cooling of process, sample, and flue gases in gas analysis applications. It efficiently reduces gas temperatures to a pre-set dew point, ensuring the delivery of dry and dust-free sample gas to high-quality gas analyzers and sensors.

Key Features:

• Explosion-Proof Design: Certified for use in gas-explosive environments (Zone 1) and dust-explosive areas (Zone 21), meeting stringent safety standards.
• Robust Construction: Features a durable IP66-rated housing, making it dust-tight, water-resistant, and suitable for outdoor installations and harsh industrial environments.
• Efficient Cooling Mechanism: Utilizes a 1200 mm long industrial stainless steel heat exchanger in a spiral form with an additional turbulator, ensuring reliable gas cooling to the desired temperature or dew point.
• User-Friendly Maintenance: Incorporates a Quick-Change-System for easy maintenance, minimizing downtime.
• Temperature Monitoring: Includes an alerting system for temperature monitoring, with an optional PT100 sensor for remote monitoring, enhancing operational safety.
• Optional Water-Trap: Integrated membrane technology provides additional protection against condensate breakthrough and dust deposits, maintaining sample integrity.
