• accurate measuring and logging of the USDA, delivery and return temperatures in the refrigerated spaces, generating alarms when necessary
• easy to use control of valves and fans to enable the holds to reach their requested temperatures
• additional monitoring, such as relative humidity and C0₂, if required

ArcticLynx™ is highly modular in design, enabling you to choose as much or as little as you need from USDA data recording to full refrigeration plant control and monitoring. Each main sub-system functions independently providing both system ruggedness and the ability to add further features or sub-systems at any time in the future. Most of the hardware is designed in-house ensuring that it can be continued to be supported for many years to come.

• A master station complex, which is normally housed in the engine control room and comprises two dual-redundant PCs, three printers, a communications system (to communicate with the outstations). From here the entire system can be viewed, controlled, settings changed, alarms acknowledged and reports printed. This also connects into the ship’s alarm system.
• A monitoring system which can monitor any or all of the following and relay the information to the master station complex:
  • USDA Points
  • air delivery and return points
  • relative humidity points
  • any digital inputs, such as fan settings
  • other machinery or miscellaneous points such as seawater temperature, brine pressure, or condenser pressure
• A control system which can control cargo hold temperatures (by either the delivery or return air temperature), operating fans and valves and communicate with the master station complex.
• A compressor control system comprising local compressor controllers communicating with a remote compressor control interface, normally located in the engine control room. This can be linked into the master station complex to print machinery logs and connect to the ship’s alarm system.

• alarm display, logging, and acknowledging
• System overview (cargo hold temperatures, relative humidity, CO₂ etc) with ability to drill down into temperature zones and then further to individual point level
• Ability to set up and view groups of points so that temperature zones can be quickly set up for new cargo
• Templates for common cargos containing pre-set setpoints, high and low alarm limits which can be applied to temperature zones. New templates can be created and existing ones changed
• Trending of up to 20 points – these can be added as a group or individually. Trending data is automatically stored for each point so you can select points to trend in real time or historically. The trend data can be saved to a USB device in a format that can be read by most spreadsheet applications
• Printer configuration is quick and easy – you can specify which printer(s) to print each of the log types and also print frequency. All logs are automatically archived and can be printed at any time. Logs can also be saved to USB media
• Voyage information can be entered and the date system date and time can be set up (UTC and ship’s time)
• Temperature zone can be quickly set up for control

• Refrigeration alarm display, logging and acknowledging
• Remote start and stop functions for each compressor and capacity control functions
• System overview of all compressors with ability to drill down to each compressor to change/view settings
• View a history of causes of stoppages
• Re-instate commissioned setting
