AzteQ offers Jacir hybrid ammonia condensers
UK: Hemel-Hempstead-based AzteQ Environmental is now offering the range of hybrid Onyx ammonia condensers from French manufacturer Jacir.
A combination of a dry condenser and an adiabatic pre-cooling section, the Onyx unit uses 80-95% less water than an evaporative condenser, with no risk of legionella.
When cooling in dry mode is no longer effective, the pre-cooling section lowers the ambient air temperature by evaporating water, which passes through humidifying pad media, specially designed for this purpose. This pre-cooled air then passes over the tube coils and condenses the ammonia. Therefore, the ammonia condensing temperature is lower than ambient air temperature.
The water in the media, which has not been evaporated is collected and recycled back to the water make-up system, without the need for water treatment.
Because condensers need to be periodically inspected and be suitably constructed for maintenance purposes, Jacir has designed the range to meet these requirements by utilising vertical H-shape tube coils and providing full access through a central door.
