Frequently asked questions about FST’s special engineering

Special engineering – individual, flexible, produced on-site

What other manufacturers call "special engineering" is a central part of the FST service: minor adjustments such as custom dimensions are normal for us. We specialise in unique. If it becomes more complex, our experts speak with you directly. This way, we understand your requirements in detail and can quickly develop the best possible solution for your company.

Our strengths, your advantage: a complete production solution all under one roof

In our production facilities, we produce systems weighing up to 70 tonnes, with pipe diameters of up to 4,000 mm and for pressures up to 1,000 bar. In addition, FST products are approved according to international standards.

FST customers ask for customised products in the following areas:

Metall working
Welding
Vessel production: Dimensions, material, approvals
Surface treatment: Sandblasting, wet painting, powder coating
Adaptation of serial products to individual spaces e.g. small vessels for low construction heights
Alternative energy sources, e.g. for adsorption dryers.
Alternative applications, e.g. technical gases such as nitrogen, carbon dioxide or helium
Entire skid systems supplied ready for use, e.g. mobile compressed air systems

Compressed air treatment made to measure – Selected projects

We cannot list them all. At FST, we simply manufacture too many special systems for our customers. However, here are five examples.

Adsorption dryer DTS8600HP

Warmregenerierter FST-Adsorptionstrockner DTS8600HP als Sonderanfertigung

This DTS8600HP heat-regenerated adsorption dryer serves as a CO₂adsorber. We designed it for a customer in the chemical and pharmaceutical industry who operates an industrial park.

Here, the compressed air dryer is used as part of an air separation plant. Air is broken down into its individual elements – e.g. oxygen, argon. During this process, the air cools down to temperatures below -150°C. Both water and CO₂freeze in this temperature range. For this reason, the DTS8600HP is installed upstream: it removes water and CO₂ from the air, makes the air extremely dry and prevents the compressed air line from freezing.

The compressed air demand and the corresponding volume flows are extremely high in this example. We have designed the system to be correspondingly powerful.

Adsorption dryer DTS1700BVLA

Warmregenerierter FST-Adsorptionstrockner DTS1700BVLA in Sonderanfertigung

The DTS1700BVLA heat-regenerated adsorption dryer operates using the closed-loop principle and is an XXL version of our energy-efficient BVL series. The special feature of this compressed air dryer lies primarily in its size.

Our Polish customer needed a special design because this adsorption dryer is located near a cooling tower. The ambient air is correspondingly humid. Our solution: a dryer that works independently of the environment.

As usual, BVL dryers are supplied with cooling water. If this is not possible or desired, as in the case of this special dryer, air cooling can be used. Accordingly, the "A" in the product designation stands for "aircooled".

Railway dryer DPS12R

Sonderanfertigung der Firma FST: Eisenbahntrockner DPS12R

Our Swiss customer uses this DPS12R heatless adsorption dryer as a so-called "railway dryer". To prevent the brake mechanism of the trains from icing up at low temperatures, the compressed air generated must be reliably dry.

The railway dryer is mounted on the outside of a railway. We have designed it to be correspondingly robust, compact and heavy duty. Every day it has to withstand loads such as falling rocks or intense vibration. Due to its compact size, we have not attached the pre- and after-filters to the vessels, as is usually the case, but a separate location nearby.

Possible pressure dewpoints

Nom. volume flow

Max. operating pressure

Adsorption dryer DTS1280VSH

Adsorptionstrockner DTS1280VSH ist eine Sonderanfertigung der Firma FST

We manufactured this DTS1280VSH heat-regenerated adsorption dryer for a Brazilian customer who uses it to dry the plant air in a refinery. As standard, the DTS V uses an electric heater to heat the regenerated air. However, this special unit carries out the regeneration process with the heat of saturated steam. (The "S" in the product designation stands for "Steam.")

This mode of operation is suitable for companies whose production process produces very hot saturated steam as a waste product. With the help of this design, our customers save significant energy costs.

In the past, we have implemented similar compressed air applications for customers in the food or pharmaceutical industry.

Adsorption dryer DTS650VH in stainless steel

Adsorptionstrockner DTS650VH der Firma FST als Sonderanfertigung in Edelstahl

The DTS650VH heat regenerated adsorption dryer was designed for a power plant that supplies energy to a copper and nickel factory in Finland. Due to the location, this dryer is permanently exposed to aggressive environmental conditions. To withstand these, we made all pipes, vessels and fittings entirely of stainless steel.
