Thermax has now introduced its 10-80 NTR hot water driven
absorption machines, appropriately named as Cogenie. This
machine uses hot water from a gas engine or micro turbine
as energy source. The introduction of Cogenie reiterates Thermax's
commitment to provide the most optimal and "best in class"
solutions for (CHPC) Combined Heating, Power and Cooling.
Cogenie
can be used in the following schemes:
Gas Engine CHP
MicroTurbine CHP
These
schemes can cater to requirements of air conditioning during
summers and space heating during winters.

Features:
10-100% Stepless Modulation:For
cooling loads ranging from 10 % to 100 % of the designed capacity, the
3-way diverting valve automatically varies hot water flow
in order to maintain the temperature of chilled water leaving
the machine.This ensures better part-load performance.
Split Evaporator Design: Special design features and
other innovations increase the efficiency considerably.
Auto De-crystallization: These machines are installed
with a unique auto de-crystallization circuit to eliminate
crystallization.
On-line Purging: The factory mounted and tested purging
unit consists of an electrical motor driven purge pump, storage
tank, necessary piping and valves. Any non-condensable gas
generated in the machine during operation, is purged continuously
into the storage tank, thereby maintaining low vacuum in the
shell.
Side Exit Nozzles: The absorber, evaporator and condenser
headers are provided with side exit nozzles for ease of maintenance
and lower down-time. The absorber and condenser headers are
hinged type, for easy access to the tube bundle and eliminate
need for heavy lifting arrangements.
Gravity Feed System: The Thermax machines use gravity
feed, non-pressurised super-spraying system, for spraying
refrigerant and absorbent. This avoids the use of nozzles,
which have the problems of clogging and wear & tear.
PLC Based Control Panel: These machines are provided
with state-of-the-art PLC based control panel with unique
display, user friendly interface and data-logging system.
Cross-over Piping: The cross-over piping from absorber
to condenser is a standard feature in Thermax vapour absorption
machines. It reduces the piping work, welding, etc. at site.
Isolation Valves for Pumps: Isolation valves provided
on the pumps, facilitate on-line pump maintenance, without
breaking the vacuum in the Thermax vapour absorption machine.
Generator Tubes:
Thermax uses: Low fin copper tubes in the generator
for LT series.
SS 430 Ti ferritic stainless steel tubes in the generator
for MT series.
SS 430 Ti ferritic stainless steel tubes in the high temperature
generator for HT series
Corrosion Inhibitors: Thermax uses the new generation
corrosion inhibitor, Lithium Molybdate which is more effective
than Lithium Nitrate and Lithium Chromate, which are conventionally
used. Lithium Nitrate can generate Ammonium Nitrate(NH4NO3)
which is harmful to copper
Optional Features:
Machine Mounted standby Canned Motor Pumps: When specified,
Thermax can offer machine mounted standby absorbent and refrigerant
pumps.
Machine Mounted Bearing Monitoring for Canned Motor Pumps:
As a special option Thermax can provide a TRG meter for machine
mounted bearing monitoring of the pumps. By continuously measuring
the bearing clearance, through eddy currents, the TRG reading
pro-actively lets the user know the health of the bearing
at any given instant.
Special Tube Material for Evaporator/ Absorber/ Condenser:
The selection of tube material is done purely on the basis
of the water quality available at the jobsite. Accordingly,
Thermax offers special tube metallurgy to enhance the life
of the machine.
Multi-sectional Shipment Arrangements: For convenience
of shipping and rigging, the vapour absorption machines can
be shipped in two or more sections depending upon the site
requirements. This is particularly beneficial for retrofit
jobs.
Factory performance Test: After assembly, the machine
can be performance tested under simulated site conditions
before it leaves the factory. The factory assembled and tested
unit considerably reduces the time needed for installation
and commissioning of the units at site.

Features:
Compact design: Cogenies are designed to be extremely
compact. This ensures minimum foot print area and provides
ease of transportation and installation.
High Efficiency: Special tube material and other innovations
help increase the COP considerably.
10-100% Stepless Modulation: For
cooling loads ranging from 10 % to 100 % of the designed capacity,the
3-way diverting valve automatically varies hot water flow
in order to maintain the temperature of chilled water leaving
the machine. This ensures better part-load performance.
Auto De-crystallization: These machines are installed
with a unique auto de-crystallization circuit to eliminate
any chances of crystallization.
On-line Purging: The factory mounted and tested purging
unit consists of an electrical motor driven purge pump, storage
tank, necessary piping and valves. Any non-condensable gas
generated in the machine during operation, is purged continuously
into the storage tank, thereby maintaining low vacuum in the
shell.

Cross-over Piping: The cross-over piping from absorber
to condenser is a standard feature in Thermax vapour absorption
machines. It reduces the piping work, welding, etc. at site.
Generator Tubes: Thermax uses Low fin copper tubes
in the generator in the Cogenie series.
Corrosion Inhibitors: Thermax uses the new generation
corrosion inhibitor, Lithium Molybdate which is more effective
than Lithium Nitrate and Lithium Chromate, which are conventionally
used. Lithium Nitrate can generate Ammonium Nitrate (NH4NO3)
which is harmful to copper
Optional
Features:
Electrical/ Pneumatic Control Valve
As an option Cogenie can be provided with Electrical/ Pneumatic
Control Valve.
Electricals
As a special option Cogenie can be offered with:
· Voltage: 380 / 440 / 460 V
· Frequency: 50 / 60 Hz
Factory performance Test: After assembly, the machine
can be performance tested under simulated site conditions
before it leaves the factory. The factory assembled and tested
unit considerably reduces the time needed for installation
and commissioning of the units at site.
