8. PRIMARY (DX) REFRIGERATION SYSTEMS
SECONDARY REFRIGERATION SYSTEMS
100% Refrigerant Charge from Compressors to Condensers to
Evaporators
Very Small Refrigerant Charge – Chilled HYCOOL Pumped to Room Coils
9. PRIMARY (DX) REFRIGERATION SYSTEMS
The primary refrigerant (NH3, R404A, R22, etc) is sent
to all zones and fills the entire system at high pressure.
Refrigerant changes state (liquid to vapor) in the
room/zone evaporators.
SECONDARY REFRIGERATION SYSTEMS
The primary refrigerant is confined to the chiller,
utilizing a very small charge of refrigerant.
A secondary fluid is chilled and pumped to each zone
at a much lower pressure.
11. HYCOOL
Turbulent
Propylene Glycol
Laminar
Comparison Between HYCOOL and Propylene Glycol
Above left & right: Comparison between fluid velocity
through a 180° bend in pipework (in fluid cooler).
Note: HYCOOL remains turbulent throughout the
entire bend and fluid velocity stays above 0.87 m/s.
Propylene Glycol drops as low as 0.57 m/s and has a
much lower average velocity.
Right: Pumping power required to move Glycol vs.
HYCOOL
13. PROVEN IN EUROPE FOR 10+ YEARS
Full-circle Simplicity
NO plant/compressor room required!
LOW MAINTENANCE

14. PACKAGED LIQUID CHILLERS PROVIDE:
Factory built pre-commissioned chillers
Factory built-in control panels and hydronics.
Less pipe work and materials.
Engineered to be compatible with Hycool
Only power supply and simple flow and return pipes needed
Low pressure < 3 bar circulating fluids throughout entire refrigeration system: plant area to cold
rooms.
High-Efficiency Hydrocarbon Refrigerants
Frigadon chillers are now available with the R1270 natural refrigerant with ZERO GWP
Use of this refrigerant can increase compressor Coefficient of Performance (COP) by 10%
Requires a smaller charge in the refrigeration circuit
16. Room Coil Selection
SIZING FLUID COOLERS
Manageable coil temperature
Low TD across coil
Wide coils with smaller fans
Minimize short-circuiting using
baffles around coils
High Air-Flow Per Bushel
19. CONTROL PANELS
Energy Management System can control refrigeration, lighting, ventilation, and more.
Demand-limiting by disabling chiller circuits and limiting rooms cooling.
Intelligent refrigeration control to minimize energy use while emphasizing product quality.
Real-time Energy Data identifies voltage, current, power, and demand instantly, rather than waiting for the
electric bill to come. Identify power-saving strategies instantly.
Combined with chillers, KILOWATCH allows new efficient methods of cooling and defrosting
20. KILOWATCH™ Energy Management System
Once pulldown is finished, fans no longer run 100% of the time
Fans run 100% during cooling, then shut down.
<50% of fans start periodically to “stir” the air
DYNAMIC STIRRING uses temperature probes throughout the room to identify
temperature differences from areas in the room.
21. Color touchscreen – Easy-to-use interface
REALTIME Energy Usage Data
Ethernet connectivity – control anywhere in the world
from a Mac, PC or Smartphone
Daily email status reports with all O2/CO2
Alarm notifications to smartphone
Export-Certified Temperature Logging Built-in
