4. µChiller Process connectivity
• Logs on serious alarms, shareable via direct link to email from
Applica Home.
• Naming each chiller you connect to
• Unit synoptic mng for faster unit commissioning
• Save unit configuration on smartphone or on cloud, to reuse or
office analyses
• Profile Management based on user skills
• Download from cloud application documentation
• FW upgrade
5. µChiller Process data logs
On selected models with Bluetooth connectivity:
• Logs on serious alarms events
• 20 variable stored, @freq of 5 seconds for 20 minutes
• Up to x 3 Events
• Log is obtainable only via Applica
• Direct Link on uChiller home synoptic for sharing:
• The alarm description via e-mail
• The logs associated to the alarm via e-mail
• Logs are also obtainable manually when connected via
Applica on Events at user discretion

µChiller Process main features
• Process machine: it works all the time.
Stops only for safety reasons.
• Cooling only mode
• Hot gas by-pass management
• Solenoid ON/OFF valve
• Solenoid modulating valve (via SSR relay)
• Modulating valve (0-10V output)
• ExV unipolar or bipolar
• Tank management
• 2 User pump management (only on
DIN versions)
• Condenser fan modulation or ON/OFF
• Independent auxiliary loop with
autotuning
7. µChiller Process Auxiliary Control Loop
Control loop with Autotuning:
• It returns a modulating analogue output (0-10V)
associated to an analogue input
• Any analogue input is selectable for enabling the
function
• PID parameters are determined automatically by
uChiller Process, based on unit operation feedback
data
It provides the user with the freedom of managing any
device (e.g. modulating pump, heater, and so on)
13. The big change
Average temperature is rising.
Natural refrigerants.
Efficiency & Energy Saving.
Climate change
14. How is the water cooled in the process industry?
• Processes with high temperature
(> 50°C) water.
• Small dimension processes with low
temperature water.
• Big dimension processes with low
temperature water.
15. How do you raise the efficiency?
• Increase of the ambient temperature →
• Increase in condensing pressure →
• More work for the compressor →
Increased energy consumption!
Back
to
the
basics!
Reduce the ambient temperature →
Energy Saving & Efficiency
18. • ChillBooster is an adiabatic air cooling system for
use on chillers, drycoolers and liquid coolers.
• It is the ideal solution for boosting cooling
capacity in air-conditioning and refrigeration
applications.
The solution:
23. Working logic
Reduce load and temperature peaks
Reduce the overall working pressure (summer)
Low working pressure → Less work for the
compressors → Energy Saving!
29. Conclusions
Thank you for your attention!
Product that aligns with the increasing request of
efficiency and energy saving
Act: Perfect for new installations →
Reduce heat exchanger dimensions
React: Ideal for retrofits →
Adapts to all the coil shapes
