Premaberg is a global supplier of moisture separation and filtration systems for the protection of sophisticated machinery and equipment mainly operating in the marine, offshore oil and gas and railway industries.

Premaberg systems provide protection for a wide range of engines, generators and HVAC equipment by keeping moisture and airborne solids OUT while letting air IN.

We take a flexible approach

Premaberg takes pride in its ability to provide equipment to meet our customers’ requirements with bespoke solutions, engineered to ensure that the design meets their specific needs.

Vane contours, angles, spacing and pitching are all critical factors, as well as the design of the catchment pockets. All of these design aspects can be tailored to meet performance criteria and special engineering requirements.

We design and manufacture equipment to meet specific applications and operating conditions, providing our customers with the ideal balance between efficiency, pressure drop, cost, weight and longevity;  manufacturing in stainless steels for strength and durability, or marine grade aluminium alloys for a more cost effective and/or lighter solution.

How moisture separators work

CFD Picture sized

At the heart of a Premaberg separation and filtration product is a bank of inertial vertical vanes. Their design causes the incoming air to take a tortuous path setting up inertial forces resulting in impingement of the moisture droplets on the vane bodies.

Each vane has multiple changes in direction and multiple catchment pockets to trap the moisture droplets separated by impingement.

These droplets drain vertically downwards to a catchment trough underneath the vane section.

Additional stages of separation and/or filtration may be added depending on individual requirements.

Designed for extremes

Premaberg separation and filtration systems are designed and tested to meet specific and challenging performance criteria. Optional testing can be arranged to include shock, blast, vibration and wind loading as required, with full test data and certification provided.

We also offer PH120 Heated Droplet Separators incorporating heat trace cabling into the structure of the separator to prevent ice build up.

Independent testing

Our commitment to supplying the very best products is underlined by the fact that our separation and filtration systems are type tested by independent testing establishments.

Product testing has been carried out to measure and prove performance for fractional efficiency, water loading capabilities, noise characteristics and equipment operation in extreme cold climates. Premaberg products are designed and proven to meet the rigorous requirements as defined by gas turbine manufacturers against the National Gas Turbine Establishment (NGTE) 30 knot aerosol input.

This ability to prove the performance of our products provides a quality separation and filtration system and peace of mind for our customers with the knowledge that our performance statements are derived from known data.

What happens to the moisture after it’s been captured?

Surprisingly this area is often overlooked, especially in exposed installations where the air intake can be subjected to heavy water loadings.  If captured water is not quickly and effectively drained away, it can be re-entrained into the air stream bypassing the separator and rendering it ineffective potentially damaging the very equipment it is there to protect.

For this reason, Premaberg moisture separators are designed and fitted with effective drainage in many forms; slots, holes, stub pipes and multi-stage systems are always fitted with manometric drain traps to ensure all captured water is efficiently drained away, even under the most extreme operating conditions.

There’s more to effective moisture removal than just a separator!

Our experienced engineers bring their knowledge to designing a separation and/or filtration system. We work with our customers to ensure the separator fully integrates with the capital equipment it is designed to protect.  We also take into account how it is to be fitted, serviced and maintained. This may include the design and provision of special housings, snow hoods, transition pieces, ducting and associated ancillaries.
