TechCold’s Core Strategies
TechCold International has built its business around the fundamental belief that to be a leader in the
global refrigeration control industry, the company must focus on the following:


People
TechCold‘s employees are highly skilled professionals who will
work for you. We can provide the information and technical
support necessary to maintain the most efficient and effective
refrigeration control solution to meet your needs. Whether it‘s
software development, PLC programming, engineering or
instrumentation…we have the people.


Research & Development
TechCold is on the cutting edge of control technology due in
large part to the never-ending efforts put forth by its
employees to keep abreast of current technologies pertaining
to the mechanical and controls side of industrial refrigeration.


Service
We have developed the infrastructure required to provide you with
sustainable, high quality service regardless of your plant location.
Through alliances with implementers and remote monitoring, we
can help you with any questions or concerns that you may have
about your system.


Quality
By focusing on designing user-friendly systems based on off-the-shelf components, offering tech support
and detailed operational guidelines, you can be assured that we will provide a complete controls package...
for today and tomorrow.


Growth
By providing non-proprietary control solutions and through developing strategic alliances with multi-national
organizations, TechCold is poised to expand its markets on a global scale.


Environment
By reducing energy, we are not only helping you increase your “bottom line”, we are helping you reduce
greenhouse gas emissions which has been proven to be a leading cause of global warming. Through our
extensive R&D efforts, we are continually researching new ways to reduce energy consumption in industrial
refrigeration applications.

Typical Integration with PLC and Remote
Testimonials
     We had two other competitors for control systems. TechCold had a great price and great service. In
 2010, we will be building a 4Plex and will be putting a new TCI Pro-Act XP Control System in the new
 facility.
 - Ms. Debbie Allen, Facilities Manager, Quispamsis Memorial Arena, Quispamsis, NB


     The staff from (TechCold) has been a pleasure to deal with. They have gone out of their way to
 give all four of the City of Fredericton arenas, all of which have Pro-Act Arena Controllers, prompt and
 efficient service…….The Controller was installed as an energy saver and has accomplished that task
 very well. We have calculated that we have received energy savings in the range of 25%.
 - Mike Murray, Facility Manager, Lady Beaverbrook Arena, Fredericton, NB


     Since we installed the TCI Refrigeration Control System, it has made life a lot easier for the
 refrigeration operators. The refrigeration plant is so stable now. This frees up a lot of time for
 the operators to do other things. We were able to cut down on the operator coverage, which is a
 substantial yearly savings. We have a lot of peace of mind with the TCI System. I can tell with one
 glance how the plant is running.
 - Bob Simpson, Chief Engineer, Atlas Cold Storage, Toronto, ON


    We are very pleased with the operation and service of our TCI refrigeration Control System. The
 system runs very smoothly, and we are already seeing significant energy savings. Our discharge
 pressure is constant and we are experiencing fewer and shorter defrost cycles. Our refrigeration
 engineers find the interface controls very user friendly and helpful in monitoring our processes.
 - Mark Ingerman, Grand Bank Seafoods, Nfld.


    The ease of access through PC remote allows regular checking and adjustments, when necessary,
 from away with a great number of changes available. It integrated smoothly with our system and has
 greatly improved control features and monitoring abilities. The ability to have power save features has
 indeed proven itself as well… we have reduced our normal bill by 15-20% on average.
 - Peter Frye, Bayside Foods Terminal, NB


    TechCold‘s product and systems knowledge has been extremely helpful. Even more important to us
 has been the extensive “hands on” familiarity and experience in the area of industrial refrigeration.
 – Joel McLaughlin, Paturel International


     We have found TechCold to be a highly dedicated and professional company with a strong drive to
 deliver a fully integrated quality solution. We found the staff at TechCold to be very knowledgeable of
 the refrigeration plant and very willing to work with ourselves and a refrigeration consultant to achieve
 a very successful project. We very much look forward to working with TechCold in the future and would
 recommend their system to any potential customers.

TechCold Solutions
Evaporator Control:
• Discharge pressure reset during hot gas defrost in order to allow reduced head pressure at other times
• Zoned control through separate temperature indications allow “load shifting”
• Anti-stratification fan control instead of continuous operation
• Separate temperature scheduler for each evaporator
• Full temperature alarms with time delays
• Adjusts the defrost frequency based on run time and time of year
• Manual defrost capability



Dynamic Compressor Set Selection:
• Screw compressors are inefficient at low slide valve settings, operates the compressors as close to a
  100% slide valve setting as possible
• Adapts well with variable speed compressors

TCI creates and models all possible sets of compressors in software. When in a period of low volatility, the
existing compressor set can be replaced with one of higher efficiency.



Dynamic Discharge Control:
• Discharge must be high enough for proper process control
• Discharge must be as low as effectively possible

TCI floats the discharge pressure based upon the ambient wet bulb conditions and the requirements of the
system. The pressure setpoint will be automatically reset to insure each evaporator has the proper defrost
pressure. Special algorithms prevent over-shoot when discharge pressure setpoint changes. Fixed, 2 speed or
variable speed fan control.
Compressor Capacity Modulation:
• Normal lead-lag control often requires more energy than necessary
• At times it is best to use two compressors for modulation while at other times, one is best
• Incorporates variable speed compressor control

TCI calculates part load ratios and determines which compressor(s) to modulate for maximum efficiency.




Ongoing TechCold Initiatives

Dynamic Suction Control:
• Too low a suction pressure wastes energy by decreasing compressor COP
• Too high a suction wastes energy by increasing evaporator runtime
• Suction can be based on the dynamic product or room temperature requirements instead of on a fixed
  pressure


TCI allows dynamic reset of the suction pressure to accommodate the present product or room requirements
instead of a “worse case” setpoint.



Refrigeration Plant Health Indication:
• Through real time analysis, TCI indicates abnormalities in the operation of the condenser, compressor
  and evaporator components such that proactive maintenance can usually restore proper operation and
  gain maximum savings
• Indications of energy use with TCI operation, what it would have been previously and what the
  potential is for further savings—all in chart form
