ADAP-KOOL® Refrigeration Control System is compact, exible,
easy to install and program and enables the solution to grow
with the application needs. This exible modular concept allows
the constantly adaptation to the application development easy
retrotting an existing installation. ADAP-KOOL® controls oer
three levels of control for dierent application demands with
growing benets and energy savings features according to your
needs:
• Local control and alarm solutions ensure accurate control and
reliable operation of refrigeration system with possibility of
HACCP compliance.
• Supervisory control as more advanced solution comprises
remote alarm with data communication, some energy savings
features with HACCP registration.
• Supervisory Control and Optimisation provides optimised
control with furthermore energy saving features like master
control, intelligent defrost, fault detection and diagnosis with
extended remote service capabilities and HACCP registration
and compliance.

Three Level of Control
ADAP-KOOL®
Compressor and condensers capacity controls are used from
relatively small basic systems with just two hermetic compressors,
to large power packs with multiple semi-hermetic compressors
equipped with variable speed drives and unloaders. ADAP-
KOOL® Pack controls oer dierent levels of solutions: From
compressor capacity control and step/variable control with local
alarm ensuring accurate control and operational condence, to
advanced solutions of control up to 12 compressors or fans with
intelligent control that optimised both suction and condensing
pressure according to the load and external temperatures.
Evaporator and cold room controls cover regulation from simple
thermostat controls with room temperature control via pump
down or compressor start/stop regulation up to electronic expan-
sion valves regulation with many intelligent functions and energy
savings. In addition, dierent levels of evaporator solutions are
oered: From local temperature control of one evaporator with
alarm ensuring easy and reliable control and operational con-
dence, to advanced control up to 4 evaporators where controllers
are capable to regulate simultaneously temperature, defrosting,
door frame, rail heat, light and fan operation. Advanced features
like defrost function, adaptive superheat control with AKV elec-
tronic expansion valve, intelligent fault detection with diagno-
sis and pulsing of rail heat and fans making possible optimal
functionality of refrigeration system saving energy and keep food
quality in display cases and cold rooms.
Variable speed control of compressors and condenser fan with
variable speed drive AKD reduces energy consumption and refrig-
erant charge as well noise level. Use of AKD stabilise condensing
pressure and reduce dirt build-up on condenser.
All ADAP-KOOL® controls are designed to be used as stand alone
or to be integrated into a complete ADAP-KOOL® refrigeration
control system solution using data communication. That enables
local or remote monitoring with alarm handling, control of your
refrigeration system and proactive service management while
reducing running costs.
ADAP-KOOL® controls in CO
2
refrigeration applications
Due environmental and cost reasons, CO
2
is becoming more and
more utilised refrigerant in Food Retail refrigeration applications.
Installation costs as well as energy costs are on the same level as
in traditional refrigeration systems without any extra costs while
the performance of refrigeration systems remains consistent.
ADAP-KOOL® refrigeration control system is designed to handle
the challenges with CO
2
. All the benets of the advanced adap-
tive control system as e.g. energy saving master control functions
can also be utilised in a CO
2
based refrigeration plant. At present
Danfoss control solutions are available for all cascade systems and
during the last years several large installations has been installed
running with CO
2
controlled by ADAP-KOOL® for both medium
and low temperature applications. Danfoss is preparing a control
solution for trans critical CO
2
system and also the necessary line
components.
