and all precautionary safety measures, in order to avoid any damage to the surroundings, materials
or installations, as well as to prevent any personal injury.
This handbook is mainly intended for use by technicians who install and operate this Condair
dehumidifier unit, who carry out preventive maintenance and who replace defective parts.
Anyone using Condair dehumidifier units, or whose responsibilities include supervising their
operation, will also benefit from reading this handbook and from consulting it as a practical help
should the need arise.
Product number for this handbook
The product number of this particular service handbook is 140712.
This is the number you need to give us if you would like to order additional copies for your staff,
colleagues or service personnel, or for technical staff from outside your company.

ABOUT MANAGING HUMIDITY
Condair humidity management technology – cost-effective and energy-efficient
The moisture in the air all around us has surprising – and often costly – effects on the materials,
structures and processes at the heart of virtually all business processes and industrial activity.
Condair 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.
And effective control of the basic parameters for your operations is good business.

SECTION 2 / THE DEHUMIDIFIER
ABOUT THE CONDAIR DA35E / DA 35D / DA 35C RANGE OF
DEHUMIDIFIERS
The CONDAIR DA35E / DA 35D / DA 35C range of dehumidifiers is designed and configured for a
wide range of industrial uses. Prominent among these is humidity management in storage facilities
and basement areas, in water works and in many kinds of process industry in which stable, well-
controlled air conditions are crucial.
DA 35E units are specifically configured to minimise the overall energy consumption of the
dehumidification process, whereas DA 35D units are configured to make sure the air flow is as dry as
possible. DA 35C units are specially designed to operate inside cold storage facilities.
The dehumidifiers in the DA 35E/DA 35D/DA 35C range are designed for easy cleaning, with
configuration options that include cooling/heating coils and/or a heat recovery module and a
condensation module and additional filters, if needed.
Design priorities
The CONDAIR DA35E / DA 35D / DA 35C range features an eye-catching modern industrial design
appearance, along with exceptional reliability.
It is designed to ensure the unhindered passage of air through the unit, which reduces
• energy consumption
• pressure losses
• noise levels
All the components, ancillary equipment and features are optimised for better performance,
exceptional service life and ease of maintenance.
Capacities
The CONDAIR DA35E / DA 35D / DA 35C range currently features models with air volumes of
between 405 m3/hr and 1,000 m3/hr.
At process air inlet conditions of 20°C and 60% relative humidity (%RH), the capacities (the amount
of water which can be removed from the air) of these units are between 3.3 kg/hr and 5.6 kg/hr.

Configuration priorities
The CONDAIR DA35E / DA 35D range is available with four different control configurations –
Configuration-A, Configuration-B, Configuration-C and Configuration-D.
Control configuration-A is stripped down to a minimum of features and is therefore not equipped with
a PLC screen interface.
Configuration-A/BASIC
The Configuration-A configuration provides:
• High dehumidification capacity
• High energy efficiency
• Stainless steel cabinet
• Easy installation
• Low-noise running
• Low maintenance costs, reducing the overall operating cost
• Easy cleaning
• Hour counter, to keep track of how long the unit has been in operation
• Attachment of external humidity sensor (external humidify control and sensors are not
included as standard, but are available for purchase from Condair)
• Mechanical hour counter, to keep track of how long the unit has been in operation
• Over-heating alarm
• Remote start/stop option
• External fault signal and operation signal
