Every refrigeration plant, which is designed for a reliable long-term operation, requires a control unit that enables
the communication between the different system parts. It is one of the most important component that guarantees
reliability and the efficient operation of the refrigeration plant.
The GEA Grasso control unit is an electronic monitoring and
control device for reciprocating and screw compressors, packages
and chillers. It provides online information on all relevant
conditions, e.g. pressures, temperatures, hours of operation, % of
capacity, safety control, alarm history file. Automatic start-up,
shut down and capacity control routines are implemented. The
automatic sequence control is an optional feature which enables to
control a maximum of eight compressor packages or chillers.

The GEA Grasso GSC TP easily satisfi es
the highest requirements of refrigeration
plants and service demands. All screw and
reciprocating compressor packages and
chillers can be controlled and monitored
by the GEA Grasso GSC TP. Predefi ned
package confi guration allows a quick
adaptation to a wide variety of applications.
A user friendly touch screen enables an excel-
lent communication interface providing an
intuitive menu structure. GEA Grasso GSC TP
also supports a wide variety of displayable
languages including Latin, Chinese,
Japanese, and Cyrillic.
Special attention has been directed to a
versatile communication capability. MPI Bus
and Ethernet are included as standard whilst
Profi bus DP, Modbus TCP, Modbus RTU,
Profi NET and EtherNET/IP are optional
features to allow communication with other
controllers on site. Optional components for
internet connectivity enable diagnostic work
and operation monitoring remotely by PC or
laptop. Up to eight packages or chillers can
be controlled by the automatic sequence
system.
The GEA Grasso GSC OP is primarily
intended to control reciprocating packages.
It is a reliable controller for all applications
with basic control requirements. The indi-
cation of important operation parameters
and alarm functions are stored for service
purposes. MPI Bus and Modbus RTU are
included as standard whilst Profi bus DP,
Modbus TCP, Profi NET and EtherNET/IP
are optional features thus allowing commu-
nication with other controllers on site.
The automatic sequence control uses the
integrated MPI Bus system. Modbus RTU
and optionally Profi bus DP are available for
special communication tasks.
