General Description; Utilisation; Design; Operating Principle - Trotec TTR 250 HP Mode D'emploi

Maintenance, Upkeep and Troubleshooting
• Perform prescribed setting, maintenance and inspection
activities when due .
• Inform the operating personnel before starting any
maintenance and upkeep work .
• Protect all installation parts and operating fluids such as
vapour connected upstream and downstream of the
air dehumidifier against unintentional restarting or re-
closure .
• Disconnect power on the air dehumidifier and protect
the main switch against unintentional reclosure before
starting any maintenance, inspection or repair activity .
• Place a danger sign to prevent re-closure .
• Check loosened screw connections for solid fit .
• Check the function of safety appliances at the end of
the maintenance activities .
Structural Alterations to the Air Dehumidifier
• No alteration, addition or remodelling of the air de-
humidifier is allowed without authorisation by the
manufacturer . This also applies to welding on sup-
porting members .
• All remodelling measures require the written confir-
mation of TROTEC GmbH & Co . KG .
• All machine parts which are not in a perfect condition
must be replaced immediately .
• Use only original spare and wearing parts .
• Third-party components do not provide any guarantee
for being designed and manufactured according to
the required stresses and strains while observing
safety specifications .
Air Dehumidifier Cleaning and Waste Disposal
• All substances and materials used must be handled
and disposed off adequately . This applies especially to
a) Work on the lubrication system and to
b) Cleaning with solvents .

cess engineering, air conditioning and for air dehumi-
products and facilities which require a particularly low
air humidity .
Air dehumidifiers equipped with electric heating may
only be operated in rooms exposed to explosion ha-
operationally reliable dehumidification at lower air
temperatures . At these points, cold dehumidifiers
cannot reach this performance for physical reasons
any longer . In addition, air dehumidifiers work by far
more efficiently under these operating conditions .

Design

The air dehumidifier is equipped completely with
rotor, fan, driving motor, heater for regeneration and
electrical system . Air humidity is adsorbed using the
silica gel rotor .

Operating Principle

The air dehumidifier works continuously using two air
flows (between 2:1 and 3:1, approximately) . The larger
process airflow is dehumidified in the rotor which turns

02. GENERAL DESCRIPTION

Utilisation

Air dehumidifiers working according to the principle of
adsorption are used to solve drying problems in pro-
dification in production and storage rooms containing
zards after having consulted the manufacturer .
Adsorption technology allows lower dew points and
