Introduction to the FDM-14: Operational Monitoring for Single-Phase Adsorption Dryers
Introduction of the FDM‑14: Operational monitoring for single‑phase adsorption dryers Smaller single‑phase adsorption dryers from DST‑Seibu Giken often lack an integrated monitoring function. As a result, it is not always immediately visible whether the dryer is dehumidifying or if a fault has occurred. Especially at installations with multiple units or unattended locations, this can lead to unnecessary service visits or delayed fault detection. With the introduction of the FDM‑14, D&F Techniek offers a practical solution. Practical upgrade for existing installations Until recently, operational monitoring was only possible if integrated during production. This increased the cost and offered no option for retrofitting. The FDM‑14 now makes it possible to equip existing single‑phase adsorption dryers with an external monitoring module. This enables users to see at a glance whether the dryer is running or if a fault is present. For locations with multiple dryers, it provides better oversight and faster alarm detection. Fewer unnecessary service visits Faults on smaller dryers are not always noticed right away, or a service engineer must visit the site only to find that the unit is working correctly. With the FDM‑14, alarms can be forwarded via volt‑free contacts, enabling remote fault detection and more efficient maintenance planning. Suitable for single‑phase adsorption dryers The FDM‑14 is developed for single‑phase adsorption dryers from DST‑Seibu Giken, but in some cases can also be used with dryers from other brands. This makes operational monitoring more accessible, without switching to a fully integrated control system.

Atmospheric airtreat drying
We prevent rust in rooms, dry products and can optimize production processes with the right air drying and treatment.
ActiGuard Activated Alumina for Water Treatment
Activated Alumina is considered as one of the best Arsenic and Fluoride removal technologies and has been applied in many applications for water treatment and environmental remediation. There is a wide range of appplications for our Actiguard portfolio: - Potable water: both Arsenic and Fluoride removal, - Bottled water: removal of undesireable ions from bottled/mineral water sources, - Industrial effluents: Arsenic, Fluoride, Phosphate, Zinc, Copper, Lead and Selenium removal, - Agriculture: phospahte removal from effluents, - Environmental remediation near sensitive aquatic environments.
AxTrap 4000
Hydrogen sulfide (H2S) and light mercaptans are common contaminants that must be removed from various gases such as air, CO2, natural gas, biogas and landfill-derived methane. Such Sulfur species are extremely corrosive and must be removed to meet fuel gas specifications, pipeline specifications and air quality regulations. We offer the AxTrap™ 4000 Series of dry, granular media scavengers to safely and effectively remove these common sulfur. AxTrap™ 4000 Series products is based on patented, proprietary mixtures of iron oxide adsorbent and/or mixed metal oxides – on an inert, inorganic carrier. The result is a particularly robust, granular adsorbent in which the metal oxide matrix provides a firmly bound active phase which is non-toxic, non-hazardous, non-pyrophoric and environmentally safe in both fresh and spent condition.

EFP Hybrid Adsorption Dryer Listed on the 2026 Energy List
EFP Hybrid Adsorption Dryer Included in the 2026 Energy List The EFP Hybrid adsorption dryer from DST-Seibu Giken combines a highly efficient heat pump with an adsorption rotor, resulting in exceptionally low energy consumption. Compared to conventional solutions, the EFP Hybrid offers energy performance up to five times more efficient than traditional (electric) adsorption dryers. Due to this exceptionally low energy usage, the EFP Hybrid adsorption dryer provides solutions for grid congestion, CO₂ reduction, and sustainability. In addition, the EFP Hybrid is included in the 2026 Energy List and is therefore eligible for the EIA (Energy Investment Allowance)*. By intelligently combining adsorption technology with a heat pump, the EFP Hybrid delivers multiple advantages. The integrated heat pump significantly reduces overall energy demand, resulting in a more sustainable and cost‑effective system. By pre‑cooling the air before adsorption, the EFP Hybrid maintains stable and controlled temperatures, making it well‑suited for temperature‑sensitive environments. Furthermore, the system operates efficiently without requiring external cooling sources, offering exceptional flexibility for a wide range of applications. The EFP Hybrid adsorption dryer is a reliable, energy‑efficient, and versatile solution for modern dehumidification challenges. *) The EFP Hybrid is listed under code 220721 on page 45 of the 2026 Energy List. The 2026 Energy List is published on the RVO website under Energy Investment Allowance (EIA). More information about the conditions for applying for the EIA in your specific situation can be found on the Dutch Tax Administration website: Energie-investeringsaftrek (EIA) | Belastingdienst.
