Case and coldroom controllers
Refrigeration controllers of the UA 300 series
are designed to control refrigerated display cases and coldrooms (both normal- and low-temperature refrigeration). The particular application - refrigerated multideck, refrigerated counter, freezer island case, walk-in freezer, etc. - and the defrost method are set directly on the controller by DIP switch.
The new UA 300 E controller for refrigeration points equipped with electronic expansion valves is suitable for all applications: chiller and freezer display cases, refrigerated counters, freezer islands and reach-ins, walk-in freezers and chillers.
Pulse-width modulation of the valves allows optimum control of superheat. The UA 300 E is capable of indepently controlling two EEVs.
All case and coldroom controllers contain an intelligent emergency operation routine covering all normal control functions.
The controllers are supplied for installation in display cases (with or without a local operator unit) and for control panel mounting. They can optionally be had with a CAN interface for networking and connection to the store computer or with internal real-time clock.
Overview of functions and features:
- Usable in all refrigerated display cases and coldrooms (chiller and freezer)
- Control of 4 to 8 add-on units in one, two or
five temperature zones
- Connection of maximum 10 temperature sensors
- Choice of three different temperature sensors
- Various defrost methods: air, electric, discharge gas, demand defrosting
- Data transfer via CAN bus, remote communication
- TTY port, compatible as substitute for controllers of UA111-UA131-UA141 series
- One-year data memory in stand-alone version
- Temperature recording for 10 seperate display cases
- Master-slave function
- Defrost times freely programmable by internal timer or external comman
Stand-alone display cases are operated using a opertor interface or other operator units. Extended operation is available with a store computer or operator terminal. Alternatively, a laptop or personal computer can be used.
