World leaders in dehumidification. Energy Saving – Reduce the carbon footprint of the dehumidifier ENERGY EFFICIENT CONTROL ECONOMICAL AND ENVIRONMENTALLY FRIENDLY With new government efficiency targets and ever-increasing energy prices, it is DST’s policy to use new technologies wherever possible. This ensures that our products continue to use energy effectively and efficiently. Our programmable logic control (PLC) systems can increase operating efficiency, lower carbon emissions and reduce running costs; factors that may be crucial for environmental certification. PLC’s are tailored to ensure highest operating efficiency is achieved for each specific project. PLC’s can be used independently, with one of our digital controllers (EH3 T2 & EH4) or interlinked with a building management system (BMS). The primary functions of the PLC are to: Provide a user friendly interface Synchronize the operation of key components Monitor protection devices, trips and alarms Adjust unit c

apacity to maintain required humidity, temperature and airflow One supplier DST offers a number of systems which controls both humidity and temperature. This means you do not need to coordinate multiple installations – everything is supplied optimised, from a single supplier. PLC for industrial dehumidifiers DST’s entry level PLC type C2 is fitted as standard to our larger industrial dehumidifiers. A user friendly keypad allows easy access to the menu options and a two-row backlit LCD screen displays important messages to the user. Used in conjunction with one of our humidity controllers, EH3 or EH4, or an external controller, BMS, the dehumidifier drying capacity can be finely tuned to accurately maintain the required set point.

r power output is regulated in two steps. Our humidity controller EH3 T2 or EH4 adjusts the drying capacity between High, Low & Off, as required to maintain the humidity (or dew point) between two programmable set points. Applications: Where precise control is not required Where process air is fully recirculated Dehumidifier capacity control is achieved by regulating the reactivation heater power Energy Saving 2 The reactivation heater power is fully regulated between zero and full capacity using linear (solid state relay or actuator) control. Using our humidity controller EH3 T2 + PLC C2 or an external control signal (BMS + PLC C2), the drying capacity is finely adjusted to accurately maintain the required set point (humidity or dew point). Applications: Where precise control is required Where the process air inlet condition is constantly changing Where a specific dry air outlet condition is required On large dehumidifiers to save energy Rotor rotation guard is included in Energ

The reactivation temperature is maintained at a high level. Using our humidity controller EH3 T2 + PLC C2 or an external control signal (BMS + PLC C2), the drying capacity is finely adjusted to accurately maintain the required set point (humidity or dew point). Applications: When using a steam reactivated dehumidifier Where precise control is required Where the process air inlet condition is constantly changing Where a specific dry air outlet condition is required Steam flow automatically adjusts to a change in air flow. Rotor rotation guard is included in Energy Saving 3 Preventing condensation and corrosion using EH3 T2 A temperature sensor attached to the coldest surface is paired with a room humidity sensor. Our EH3 T2 simultaneously monitors surface temperature, relative humidity and dew point of the room air

. Our humidity controller EH3 T2 accurately adjusts the drying capacity to maintain the required RH set point. Should the air dew point exceed the monitored surface temperature, EH3 T2 will automatically override the RH set point, increasing its control output to the dehumidifier. EH3 T2 regulates the drying capacity to control both RH and dew point while ensuring least possible energy is consumed.
