Standard Rectangular Moisture Eliminators

The moisture eliminator is a key element of a properly engineered engine room ventilation system. These filters are designed to fit into the rough air openings for the engine room and will remove the salt and water from the intake air. This important component of the ventilation system is often overlooked. Removing the salt and moisture from the engine room intake air will not only enhance combustion, but will also greatly reduce maintenance costs on all equipment within the engine room. A properly designed moisture eliminator will filter out water particles down to ten microns or smaller in size, and will also be able to handle a driving rain or even green-water conditions.

Description

The Delta "T" Systems moisture eliminator is an impingement type separator that has been designed for vertical installation and horizontal airflow filtration. It is most often used to filter the water out of the air that is drawn into a vessel's engine room, however, because of its very effective performance characteristics it has been used in many other marine applications where an ample supply of clean dry air is required.

The individual profiles of the moisture eliminator are specially curved and shaped to turn the airflow as it passes over the profile surface. As the entrained liquid droplets have a higher mass than the air, the liquid cannot make the turn as easily as the gas flow, and inertia forces the droplets against the surface of the profile. The liquid forms a film that is pushed along the profile into an area of low pressure located behind the hook. The liquid film is allowed to coalesce into larger droplets and then drains out via gravity at 90° relative to the airflow. The specially curved shape of the Delta "T"Systems moisture eliminator provides a low drag coefficient that allows higher velocities without excessive pressure drop. At higher velocities, smaller drops are removed due to increased inertial forces, and higher efficiencies are achieved.

As a pioneer in the field of marine moisture elimination, Delta "T" Systems has more than 10,000 vessels using this technology around the world.

Function and Operation

This moisture eliminating air filter is an impingement type separator designed for vertical installation and horizontal airflow. The individual profiles are specially curved and shaped to turn the airflow as it passes over the profile surface. As the entrained liquid droplets have a higher mass than the air, the liquid cannot make the turn as easily as the gas flow, and inertia forces the droplets against the surface of the profile. The liquid forms a film that is pushed along the profile into an area of low pressure located behind the hook. The liquid film is allowed to coalesce into larger droplets and then drains out via gravity at 90° relative to the airflow. The specially curved shape of the Delta "T" Systems moisture eliminator provides a low drag coefficient that allows higher velocities without excessive pressure drop.

Type and Materials

Profiles are available in white or black PVC, Aluminum or stainless steel. Housings are available in PVC or Aluminum, and are custom designed for a specific application's size and airflow requirements. The profile packs can be used as a single stage for optimum pressure drop characteristics with good particle separation (10-20 Micron range) or in multiple stage systems using a coalescing material to optimize the particle separation (1 – 10 Micron range). It is our objective to design each system for maximum particle separation, minimum pressure drop, opening size, and weight for a minimal cost. We will work with you to provide as much, or as little, engineering assistance as you might require. Marine system design is the specialty of Delta "T"Systems. With the thousands of proven applications completed, we have a system or a product to fulfill your needs and budget.
