 CONTROL
SYSTEM PRODUCT LINE
Our
control system product line is different from all of
our competitors in that it is scalable from equipment
control, such as a screw or reciprocating compressor,
to full plant control. One common scalable hardware
and software solution does it all.
The
M&M Refrigeration control system product line is
comprised of three main product groups to meet the needs
and budgets of any customer.
 |
Compressor
Control Systems (CCS) |
|
“Off
The Shelf” Control Systems (OTS) |
|
Engineered
Control Systems (ECS) |
HARDWARE

SOFTWARE
OVERVIEW
Our
control system software is built around a core infrastructure
providing the basis for everything we do. The way data
is displayed, the navigation of screens, alarm processing
and logging of data are all standard features in every
microprocessor product we produce.
Every refrigeration control software function is designed
to be easily adaptable to meet our customer’s
needs. The list of software functions continues to grow
with an ever-expanding set of standard features and
options.
This
approach allows us to deliver products with a common
look and feel, software that is fully tested, the ability
to support all levels of facility complexities and provide
a system to meet any budget size. Some of our software’s
key features include:
|
Standard
infrastructure (displays, logs, alarm processing) |
|
Standard
software packages |
|
 |
Screw
compressor controllers to retrofit all major manufacturer’s
units |
| |
|
Reciprocating
compressor controllers to retrofit all major manufacturer’s
units |
| |
|
“Off
The Shelf” controllers such as evaporator
panels, condenser panels, pump package panels and
ice rink skid panels |
| |
|
Stand
alone controllers for ice machines, spirals, chillers,
engine control, etc. |
|
Many
options available in each module |
|
What
a user friendly interface should look like: |
|
|
Meaningful,
readable displays with information organized by
function, making the system easier to use |
| |
|
Transfer
of training — consistent user interface across
all product
lines including PC software; you only need to learn
one system |
| |
|
“At
a Glance Technology” — data formatted
and highlighted
for quick reference by the operator |
|
Logs
— extensive logging capability provides a
very useful diagnostic tool for isolating system
problems |
|
Alarms
and failures — extensive alarms with names
in user-friendly text |
