Compressed air dryers

For high quality requirements: Compressed air adsorption dryers from FST achieve extremely low pressure dew points of up to -70°C.

Our heat-regenerated adsorption dryers of the DTS V, DTS BVL and DTC series  are particularly suitable for drying large volume flows. These flexible and high-performance compressed air dryers are a reliable and economical solution for achieving very low pressure dew points at variable volume flows.

Meanwhile, heatless regenerated adsorption dryers of the DPM, DPS, DHM and DHW series dry small to medium compressed air volumes. Thus, they are a solid choice for drying small to medium volume flows, up to high-pressure applications. If no power supply is available, these heatless adsorption dryers can be equipped with a pneumatic control, and can then also be used in potentially explosive atmospheres.

FST customers use adsorption dryers in installations that are at risk of freezing, among other things. Another area of application exists in particularly demanding compressed air applications in the food, chemical, and pharmaceutical industries (incl laboratories).

Our reliable compressed air refrigeration dryers are made for basic drying: FST customers use the cost-effective basic dryers of the DFLO and DFLO ES series in all types of compressed air applications. With pressure dew points of up to +3°C, they dry the compressed air reliably and with satbility. This means there is no condensation in the compressed air line and operation is assured.

A solid basic unit: Our DFLO refrigeration dryer impresses with a hot gas bypass control that makes it compatible with many volume flows. This means that its performance can always be optimally adapted to that of the air compressor used. Particularly safe: the standard microprocessor control with potential-free contact.

When energy saving is a priority, our DFLO ES("Energy Saving")refrigeration dryer comes on the scene. We equip our most energy-efficient compressed air dryer with a thermal mass storage unit as standard. When demand is low, the compressed air refrigerant dryer goes into stand-by mode – and then consumes no energy at all. These features make it the optimal solution for fluctuating volume flows or inlet temperatures (e.g. in summer/winter operation).

Precise and space-saving: Our membrane dryers are particularly suitable as point of use dryers. Our DM-SWC and DM-FP FST dryers are used whenever compressed air is to be specifically treated at the point of use. These compressed air dryers are particularly suitable for drying smaller compressed air flows. Depending on the inlet temperature, they achieve an impressive pressure dew point reduction to as low as -40°C.

When dry is not dry enough: Our dew point booster of the DTS HPI series is an after-dryer for medium volume flows of up to 1,000 m³/h. It is normally used in compressed air treatment, in addition to a fridge dryer or other compressed air dryer. This heat-regenerated adsorption dryer reduces the residual moisture of already pre-dried compressed air to considerable pressure dew points far below -40°C.

Highly energy-efficient: Our dew point booster works with a small, maintenance-free ceramic heater, and thus keeps energy losses extremely low.

Customers often use this post-dryer as a supplement in winter operation. Because it works completely independent of the environment, it can be used worldwide in all climate zones. Due to its compact size and low energy consumption, the pressure dew point booster is ideally suited for use in compressed air containers as well.

Absolutely dry, absolutely safe: cartridge point of use dryers of the FCA CMS series are suitable for use as spot-on final dryers. In sensitive applications – e.g. for laboratory measurement equipment – our customers use them directly upstream of the device. Here they remove any residual moisture from compressed air. Their speciality is the short-term drying of small quantities of compressed air to pressure dew points below -40°C.

How can we guarantee such a high degree of drying? We use only highly effective desiccants in this compressed air dryer. In addition, we use an integrated after-filter that captures dust and abrasions.

FST customers from the laboratory and measurement technology contexts appreciate these high-performance compressed air dryers. They are also used for printing machines or for all compressed air applications with low compressed air requirements.
