Pre-cooling units
Being able to control the exact specifications of the air entering the dehumidifier enables you to
extract maximum benefit from Cotes humidity management.
Cotes C35E/C35D dehumidifiers can therefore be fitted with cooling units to reduce and/or control the
temperature of the dry air entering and leaving the dehumidifier.
A cooling unit fitted before the adsorption rotor is particularly beneficial if the incoming process air is
very warm and humid. In such cases, some of the water in the air condenses and the efficiency of the
adsorption rotor increases. A cooling unit fitted before the adsorption rotor can also be an advantage
if the outgoing process air has to be especially dry.
Pre-cooling units can be retrofitted to C35E/C35D dehumidifiers with the Configuration-B,
Configuration-C and Configuration-D.
For details about any pre-cooling units fitted to this particular Cotes dehumidifier, please contact your
Cotes dealer, or Cotes.
Post-cooling unit
Cotes C35E/C35D units can be fitted with post-cooling/heating units to maintain full control of the
temperature of the dry air leaving the dehumidifier.
Post-cooling/heating units can be retrofitted to C35E/C35D dehumidifiers with the Configuration-B,
Configuration-C and Configuration-D.
For details about any cooling units fitted to this particular Cotes dehumidifier, please contact your
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.
The heat exchanger is placed in an external box equipped with inlets and outlets for the incoming and
outgoing regeneration air.
The heat recovery unit can save as much as 20–25% on energy consumption, but you have to install
the appropriate ducting and damper for outgoing regeneration air.
For details about the heat recovery unit fitted to this particular Cotes dehumidifier, please contact
your Cotes dealer, or Cotes.
