Energy recovery components
Plate type heat exchangers
Plate type heat exchangers are typically made of aluminium. Their service life is virtually unlimited. Maintenance is
limited to cleaning operations.
• Clean the condensate drain pan, check the siphon and fill up as necessary.
• Any accumulation of fibres or dust on the exchanger may be removed with a hair broom or vacuum cleaner.
• Any oil or greasy deposits must be removed. Make sure the bypass damper (if any) is operating properly.
If a bypass damper is fitted, maintain as suggested in above Dampers section.
Heat wheel
Refer to the manufacturer's instructions for proper maintenance of the wheel, wheel drive and motor. The construction
of the matrix is such that it is virtually completely self-cleaning. The rotor may be cleaned with pressurised air, water or
steam jet and domestic household detergents as necessary.
Heat pipe exchangers
Heat pipe exchangers have no drive mechanisms or moving parts. Maintenance consists in cleaning operations,
cleaning of the condensate drain, checking the siphon and filling as required.
To clean the fins:
• Blow out with pressurised air against the direction of the air stream or spray with low pressure water. If necessary
add house hold detergents.
• If a bypass damper is fitted, maintain as suggested in above Dampers section.
Unit waste disposal
A standard air handling unit is made up of 95% recycling metal materials. Unit insulation is performed with foam
polyurethane injected into the unit panels. Air filters made of synthetic fibres are available. The special materials
employed are listed in the attached technical sheet relating to the unit.
The unit or part disposal must be performed in accordance with application regulations.
Note: Regular maintenance is critical for the long lifecycle of all air handling units. Trane Service is available for any
problem or advice.
Maintenance Plan
The following table lists suggested maintenance intervals for the CLCF air handling unit based on experience and
under normal running conditions. They are based on continuous running operation per 24 hour period in moderate
climatic zones with minimal dust pollution as would normally occur in reception areas or office accommodation.
Widely different operating conditions, particularly in respect to air temperature, humidity and dust pollution will
considerably shorten the maintenance intervals.
