Specification
Halton’s DSH high efficiency droplet separators are designed for demanding applications such as marine, oil & gas, chemical, energy industries, where reliability, easy installation and special design play an important role. Droplet separators operate on the principle of inertial vane separation and are designed to restrict the penetration of moisture, salt spray, rainwater and airborne aerosol particles into HVAC systems, engine room intakes, machinery spaces, and diesel and gas turbine engine air intakes.
Three configurations are commonly used according to the level of droplet removal efficiency required, single stage, two stage, and three stage, but special configurations are available. Two and three stage units will include a coalescing and particulate filter. Halton is able to assist in the design and selection of the droplet separator according to the application with special consideration to the pressure drop, velocity, wind speed and direction, turbulence, and drainage.

Optional features
Service hatch (SH)
Enables easy access to the filter from the side of the unit. Hatch can be placed to the left side (HL) or the right side (HR) of the DSH. (ISO Coarse 70% panel filter in the picture).
Iso Coarse 70% panel 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% and 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 a damper
Halton droplet separator can be connected to a Halton Marine fire damper with or without a connection piece. In both cases the construction is modified to fit the damper. Connecting DSH together with a 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 (including 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.
Weathertight hatch
Weathertight hatch is used e.g. to shut down the intake close to the waterline in the event of rough seas.
