DSA – Droplet Separator with Heating

Halton’s DSA high-efficiency droplet separators are designed for demanding applications such as oil & gas, chemical, energy and marine industries, where reliability, easy installation and special design play an important role. Droplet separators are designed to restrict the passage of moisture, salt spray, rainwater and airborne aerosol particles e.g. into HVAC systems, engine room intakes, machinery spaces, and diesel and gas turbine air intakes.

Specification

DSA droplet separators are fitted with heating elements. The regulated temperature is subject to the surrounding conditions. The actual surface temperature of the heated DSA depends on many variables such as the size of the separator, wind circumstances, face velocity, air temperature and relative humidity. Electrical heating capacities vary between 2,5 kW/m2 – 3,7 kW/m2, depending on these conditions. The cable heating does not prevent icing in the most severe conditions, but it will help defrost the ice when the icing conditions have passed.
When intake air is crucial during extreme icing conditions the Halton ECS (Extreme Conditions Solution) keeps the air intake open. The ECS is available as an option.

Optional Features

The Extreme Conditions Solution (ECS)

When intake air is crucial during extreme icing conditions, the Halton Extreme Condition Solution (ECS) keeps the air intake open. The Halton ECS combines the DSA heated droplet separators with either shut-off or fire dampers with an additional option for filter units.
The solution can allow one or more separators to remain open and ice-free while the other separator is in defrost mode during critical atmospheric conditions.
This is achieved by shutting-off a section of the DSA to allow the ice build-up to melt.
There are a few control methods available to alternate the opening/closing sequence of the ECS to ensure a free flow of unrestricted air.

“Gooseneck” – Reducing the wind effect

Strong wind can adversely affect the performance of the droplet sepator. In environments where stormy weather is regular Halton recommends using a “gooseneck” air intake with droplet separators. A gooseneck can be installed directly to a duct installation type of droplet separator.

Filters

Please note: filters installed in DSA require always a separate frame.

ISO Coarse 70% filter

Panel filters are manufactured of progressive thermally smoothened synthetic polyester having high dust holding capacity and constancy for humidity. The filters are used in general ventilation system for air purification.

ePM10 70%, ePM2,5 65%, ePM1 50% Bag filters

The materials of the synthetic fine filters are high-quality and durable, progressive mounted synthetic fibres. The filters can be used in example for air purification of intake air.

ATEX approved filters

Halton Marine also offers ATEX approved filters for droplet separators.

Installation in conjunction with damper

Halton droplet separator can be connected to a Halton Marine damper with or without a connection piece. In both cases the construction is modified to fit the damper. Connecting DSH together with a fire damper must be mentioned when ordering products. Special flanges and drilling patterns are available for all models on request. The structural flexibility of dampers and high-quality combined with a wide range of accessories (ex-actuators) and special steels, enable Halton Marine to offer tailored solutions for its customers.
Combining Halton Marine droplet separator to damper offers customers a compact solution for air intake that also saves space. The products are recommended to be connected together at Halton Marine factory.

Weather tight hatch

Weather tight hatch (WTH) is used e.g. to shut down the intake close to the waterline in the event of rough seas. See a separate brochure on weather tight hatch called Halton WTH.
