THE PROBLEM:
condensate
• It washes away lubricant oil from tools and equipment
causing more rapid wear and an increase in
maintenance costs.
• It corrodes pipelines creating rust particles and others
which then get carried downstream to the pneumatic
equipment.
• In spray painting it can spoil the finished product and
create sites where corrosion initiates.
• In sand or shot blasting it can block nozzles and cause
rapid oxidation of the treated surface.
• It is potentially dangerous in pharmaceutical
applications.
• In the electronic industry it can simply not be tolerated.
• In pneumatic conveying it creates blockages and
contaminates the product itself. For example:
a compressor with an air intake of 3.600 m3/h, at 25°C
ambient and relative humidity of 60%, will also be
drawing in a considerable quantity of water vapour.
Almost 37,9 l/h will be eliminated by the aftercooler at
the outlet of the compressor, but this still leaves a further
19,5 l/h which can be removed by a refrigeration dryer
to provide technically dry air with a pressure dewpoint
of 3°C.
Microprocessor
TDC: Total Dry Control
Microprocessor control PcO Xs
The main operating parameters of the dryer are shown in the dual
display at all times. Under normal conditions both the dewpoint
and compressed air inlet temperatures are shown in numerical
format. The graphic icons make reading of the various values and
main alarms quick and simple. Four control keys complete the
user interface.
Functions:
• Visualisation of the following parameters:
- unit status
- air inlet temperature
- evaporator outlet temperature
- time and date
• Control of the compressor status and Energy Saving
function.
• Monitoring and display of the main parameters of the air
and refrigerant circuits.
• Self diagnostic system.
• Alarm system on air and refrigerant circuits.
• Digital input for remote ON/OFF.
• General alarm relay.
• Alarm memory storing last 50 recorded events.
• Record of the main parameters of the air and refrigerant
circuits at the moment of each alarm event.
• Password protected reset of event memory.
• Weekly programming option.
• Multilevel menu with password protection.
• Easy connection to a PC.
• Options on request:
• Remote alarm system via GSM
• “PlantWatch” system
• Connection to a PLC system (Modbus, LonWorks,
Profibus, Bacnet, Metasys, Trend)
• Remote display kit (max. 200 metres).
Some parameters may be simply and rapidly adjusted by the user,
helped by the dual display showing both the name and the value
of the parameter in question.
With TDC there is also the opportunity to connect a second
terminal for full remote control of the dryer while connection to a
Building or Energy Management System can be achieved with an
RS 485 port using the MODBUS protocol.
Functions
• Monitor air inlet temperature;
• Monitor air outlet temperature (permanently displayed);
• Monitor dew point temperature (permanently displayed);
• Management of timed drain opening and interval times;
• Management capacitance drain;
• Management of up to 15 alarms;
• General alarm relay;
• Digital input for remote ON/OFF;
• Multilevel menu with password
• RS485 serial port with MODBUS-RTU protocol;
• Alarm memory storing last 50 recorded events with password
reset.

Casing
• Cataphoresis treatment of
the manifolds;
• Option of centrifugal fans;
• Option of copper-copper
coils for marine
enviroments;
• Condenser coils on one side;
• GSM system.
All MTA dryers are designed,
manufactured and marked to
CE standards.
The casing is made from
galvanised steel finished with
an oven-baked polyester
powder coating in RAL 7035
white. Key locks provide easy
and controlled access to the
control panel and electrical
compartment.
Refrigerant circuit
Condensate drain
Models from MG 022 to MG 110 inclusive have a single
refrigerant circuit with one refrigerant compressor, while models
from MG 150 to MG 190 have a single refrigerant circuit with two
compressors.
The refrigerant compressors are of the fully hermetic reciprocating
type with anti-vibration mountings.
The cooling capacity is controlled by a refrigerant hot gas bypass
valve, which maintains a constant dewpoint under all load
conditions. On models from MG 150 to MG 190 the capacity is
controlled by a combination of the hot gas bypass valve and,
when possible and to save energy, the alternate cycling of the two
compressors.
The condensate drain is either a timed solenoid valve or
alternatively a capacitance drainer. Both systems are complete
with isolating valve and strainer.
In the case of the timed drain the opening and interval times are
set via the microprocessor control while the capacitance drain has
its own management system with any faults signalled via the
display on the main microprocessor control.
The condensate drain manifold is made from carbon steel.
Heat exchanger
High efficiency compact aluminium module containing:
• Air/air heat exchanger.
• Air/refrigerant heat exchanger (Evaporator).
• Demister type condensate separator with AISI 304 stainless
steel mesh.
Highly efficient and compact, it permits a modular construction
satisfying the technical demands of the whole range.
Principle of Operation: The compressed air enters the air/air
exchanger where it is pre-cooled by the cold dry compressed
air leaving the evaporator. It then passes to the air/refrigerant
exchanger (evaporator ) where it is cooled to the final dew point
temperature by the evaporating refrigerant. The condensate
produced during the cycle is separated in the high efficiency
demister separator and drained.
Finally the cold dry air passes back through the air/air heat
exchanger where it is reheated in contraflow by the warm wet
inlet air. The cooling required for the compressed air to attain
the required pressure dew point of + 3°C is produced by the
refrigerant circuit with its capacity control system automatically
and rapidly responding to any variations in the flow rate and inlet
temperature.
Control Panel
The ergonomic design of the control panel layout ensures
maximum ease of use for operation and maintenance.
Controls are on the front panel of the dryer and comprise:
• Distribution board with mains isolator.
• Control devices:
- High pressure switch.
- Fan pressure switch (only for air cooled versions).
- Low pressure switch for models MG 022 – 110.
- Low pressure transducer for models MG 150 – 190.
- Refrigerant pressure gauges.
- Air pressure gauge (positioned at the rear).
• Thermostat on the refrigerant compressor discharge.
• IP54 protection grade
Condenser
The position of the refrigerant condenser, located at high level on
one side of the dryer, provides optimum maintenance accessibility
with the minimum of space requirements.
For models from MG077 to MG190 inclusive, there is the option
of condenser cooling air intake filters for enhanced performance in
dusty or dirty environments.
• Air cooled versions: the condenser coils comprise copper tubes
with aluminium fins and a galvanised frame, complete with
axial fans and safety grilles.
For marine environments condensers with copper fins and brass
frames are available as an option.
Centrifugal fan versions are also available where ducting of the
condenser airflow would be of benefit.
• Water cooled versions: the condensers are of the stainless steel
brazed plate heat exchanger type. All models can be supplied
with a water flow regulating valve for control of condensing
pressure.
