  • Page 5: About Managing Humidity

    Cotes humidity management technologies enable you to control the levels of moisture in the air inside any building, installation or facility, using only a bare minimum of energy.

  • Page 6: About Cotes

    6/92 ABOUT COTES World leader Cotes is one of the world’s leading experts in the field of adsorption dehumidification, providing technology and expertise that enable companies to achieve better control of the humidity always present in the air. Better management of the humidity in the air also makes it possible to improve and optimise a wide range of industrial processes, prevent damage and corrosion in many types of structures, and reduce energy consumption in all kinds of installations where air specifications are important.

    (quickly), or reducing the humidity more slowly but using less energy. Dehumidifiers in the CRP/CRT Flexible range can be powered by different energy sources. Cotes provides models fueled by Electricity (E), Steam (D) or Gas (G) as standard – but the use of other energy sources or mixed-energy configurations can be designed to meet costumer request.
  • Page 8 All the components, ancillary equipment and features are optimized for better performance, exceptional service life and easy maintenance. All components (except HR module) are mounted inside the Cotes CRP/CRT cabinet, which can be extended to house extra components if needed.
  • Page 9 CAPACITY CONTROL configuration In addition to the STANDARD configuration, the CAPACITY CONTROL configuration provides: • Modulating capacity by a 0-10 V external signal. Can be controlled by BMS system or Cotes controller FLEXIBLE configuration All dehumidifiers in the CRP/CRT Flexible range can be customised to suit a specific need – hence the name.
  • Page 10 COTES CRP/CRT INSTALLATION, OPERATING AND SERVICE HANDBOOK page 10/92 It is only possible to deviate from these ranges if such deviations were specifically mentioned when the order was placed, and special considerations have been incorporated into the unit in order to deal with this.

  • Page 11: How It Works

    HOW IT WORKS Two flows of air The effect of Cotes adsorption dehumidifiers basically stems from the action of two flows of air. The drying process (1–5, black) The incoming moisture-laden flow of air (process air) enters one side of the cabinet and gets filtered by a process air filter.
  • Page 12 Cotes dealer, or Cotes. Heat recovery unit (HR module) Cotes adsorption dehumidifiers can be fitted with a heat exchanger to make sure that part of the thermal energy from the regeneration air leaving the unit is extracted, and reused for preheating the incoming regeneration air.
  • Page 13 The heat recovery unit can be fitted to any CRP/CRT dehumidifiers, but you have to install the appropriate ducting and damper for outgoing regeneration air. For details about the heat recovery unit fitted to this Cotes dehumidifier, please contact your Cotes dealer, or Cotes.

    COTES CRP/CRT INSTALLATION, OPERATING AND SERVICE HANDBOOK page 22/92 INCLUDED APPENDICIES AND SPECIAL NOTES This manual gives general data regarding all dehumidifiers in the CRP/CRT range. For data concerning the specific dehumidifier please see the appendix section. The following data are found in the appendix:...

  • Page 23: Section 4 / Installation

    Handling Cotes dehumidifiers are built to be very robust, so there is no need for special handling, apart from normal sensible care and attention. Note the weight of the dehumidifier as specified in appendix We recommend that you use a forklift to move the dehumidifier around and place it in position.
  • Page 24 COTES CRP/CRT INSTALLATION, OPERATING AND SERVICE HANDBOOK page 24/92 Things to be careful about Electrical work should only be carried out by an authorised electrician. NOTE Electrical work should only be carried out by an authorised electrician. Connections needed – electrical First, make sure that the main switch is OFF.
  • Page 25 COTES CRP/CRT INSTALLATION, OPERATING AND SERVICE HANDBOOK page 25/92 A damper for adjusting the regeneration air flow must be installed unless an inverter for regeneration is include in the dehumidifier (not standard). If not, the regeneration air flow will – in most cases – be too high, making it impossible to reach the desired temperature for the regeneration air and thus making the unit less efficient.
  • Page 26 Please consult appendix 1 for details about how to connect the steam coils. Cotes recommend that the installation be fitted with a valve that closes the flow of steam when the dehumidifier is not operating.
