Dehumidifier Maintenance

Industrial dehumidifiers play an important role in controlling moisture levels, protecting product quality and supporting reliable production. Once installed, these systems depend on regular and well-planned maintenance to keep performance stable and energy use predictable. At Newsome, we provide a full maintenance service for industrial dehumidifiers from many manufacturers, not only SEIBU GIKEN DST AB. Our experience covers decades of working with a wide range of models and control systems across many industries, giving us a detailed understanding of how to keep equipment operating at its best. We support companies across the UK with responsive maintenance, planned servicing, breakdown support and long-term agreements. With regional account managers, experienced engineers and a strong service infrastructure, we deliver reliable ongoing care that keeps humidity control systems in good working order.

    The Importance of Proper Dehumidifier Maintenance

    A well-maintained dehumidifier delivers stable moisture control, steady airflow and consistent performance. Over time, components such as filters, rotors, fans, heaters and sensors can begin to show wear or become obstructed by dust and particles. Without regular checks, performance can drop, energy use can increase, and the risk of unplanned downtime becomes greater.

    Regular maintenance offers clear benefits:

    • Improved system efficiency
    • Stable humidity levels
    • Longer equipment life
    • Reduced downtime and callouts
    • Accurate control and monitoring
    • Lower energy costs

    These benefits support production reliability and help protect valuable products, materials and processes from moisture-related issues.

    Our Experience with Multiple Manufacturers

    Here at Newsome, we have decades of experience maintaining dehumidifiers from many brands. Although we are an approved partner of DST, our maintenance knowledge extends far beyond this product range. We maintain:

    • DST systems
    • Older and legacy industrial dehumidifiers
    • Units from other global manufacturers
    • Custom-built dehumidifiers
    • Desiccant and refrigeration-based systems

    This broad experience makes us a practical choice for sites where multiple brands are installed or where older units require specialist attention. Our engineers understand different control systems, reactivation methods, airflow arrangements and component designs, allowing us to diagnose issues accurately and propose reliable solutions.

    A Complete Maintenance Service

    We provide structured maintenance support that covers routine inspections, performance checks and corrective work when required. Our approach ensures each system continues to meet the original performance targets and remains aligned with your environmental control needs.

    Routine inspections are designed to identify early signs of wear or performance drift. These visits include:

    • Checking airflow rates
    • Inspecting filters for dust build-up
    • Assessing rotor condition
    • Testing reactivation heaters
    • Inspecting belts, motors and fans
    • Examining seals, ducting and insulation
    • Checking for water ingress
    • Verifying sensor performance

    These checks help prevent issues from developing into major faults.

    Filters play a key role in protecting internal components from airborne particles. A blocked filter can reduce system capacity and increase energy use. During maintenance visits, we inspect, clean or replace filters depending on condition. We can supply G4 and F7 filters, as well as other filter grades used by various manufacturers.

    Desiccant rotors lose performance gradually over time due to dust, moisture and natural ageing. Our engineers assess rotor operation, verify rotation speed and check for areas of wear. Early intervention helps maintain the correct moisture removal rate and ensures your system continues to meet humidity targets.

    Industrial dehumidifiers use electric, steam, gas or hot water reactivation. Each method requires regular checks to confirm correct and safe operation. We test:

    • Electric heater elements
    • PTC heaters
    • Steam valves and steam lines
    • Gas control systems
    • Temperature sensors
    • Safety cut-outs

    This ensures the reactivation process works reliably and safely.

    We test electrical panels, contactors, relays, PLC controls, sensors and wiring connections. For systems linked to a building management system, we confirm that all communication signals are working correctly. Accurate control ensures the dehumidifier responds properly to changes in humidity and temperature.

    Internal and external cleaning helps maintain airflow, improve energy efficiency and protect the system from dust and moisture. We clean:

    • Internal panels
    • Fans and housings
    • Heat exchangers
    • Sensors
    • Ductwork sections (where accessible)

    This supports smooth operation and reduces mechanical strain on components.

    Many customers choose a planned maintenance programme. This provides scheduled visits throughout the year based on system size, usage, environmental conditions and production requirements. Planned maintenance helps avoid unexpected breakdowns and keeps humidity levels steady even in demanding applications. Each plan is tailored to site requirements and includes detailed service reports, performance logs and recommendations for improvements where needed.

    Despite best efforts, faults can occur, especially in high-demand environments or older systems. Our service engineers provide responsive support across the UK. Calls are handled by our national service desk, and engineers are dispatched from our regional hubs. We provide:

    • Breakdown repair
    • Fault finding
    • Component replacement
    • Temporary humidity solutions if required

    This approach reduces downtime and helps restore stable conditions quickly.

    We hold stocks of essential spare parts for DST units and can source components for other brands. Our relationships with suppliers allow us to obtain motors, filters, rotor seals, sensors, belts, bearings, heaters and control components with short lead times. For older or discontinued models, we can often repair or upgrade components to improve reliability.

    Maintaining Systems in Complex Environments

    Industrial dehumidifiers often operate in demanding or sensitive environments, including:

    • Food processing
    • Pharmaceutical production
    • Chemical plants
    • Warehousing and cold stores
    • Precision manufacturing
    • Printing and packaging
    • Plastics and rubber production
    • Research facilities and laboratories

    We understand the importance of stable humidity in these settings. Even a small change can affect product quality, drying times, storage conditions or compliance. Our maintenance plans focus on keeping conditions stable and predictable across changing temperatures, seasonal variations and production demands.

    Supporting Older Systems and Upgrades

    Many facilities use dehumidifiers that have been in operation for ten to twenty years. We regularly maintain older units and can advise on upgrades that improve energy use, capacity and control accuracy.

    Typical upgrades include:

    • Energy-efficient heater elements
    • Improved insulation on ducting
    • Modern sensors with better accuracy
    • Updated control panels
    • BMS integration
    • Replacement desiccant rotors

    Our team can also assess whether repair or replacement offers better long-term value.
