TIMERS 1 Robertshaw® proprietary and confidential ©2014 DEFROST TIMERS SERVICE COMPONENTS PRESSURE CONTROLS TEMPERATURE CONTROLS Applications Refrigeration System Why Defrost Control? Existing Product Line UL873 Vs. UL917 Relay Information Manufacturer Comparison Q&A Both mechanical and electronic controls are rated to UL873 commercial refrigeration standards ie. 30,000 cycles Controls allow for a more precise termination of the defrost cycle based on temperature or pressure value Manufactured products for the refrigeration industry since 1905 Controls are often called defrost timers because most popular method of defrosting equipment is based on a time schedule Easy to install and program especially in retrofit applications Commercial Refrigeration Applications Refrigeration equipment Reach-In Coolers or Walk-In Freezers Prevents unwanted build-up of frost or ice Shuts off the compressor electric or alters its function (hot gas defrost) Helps maintain the refrigeration equipment’s ability to remove heat from the controlled space Defrost Control Pressure Control Temperature Control Ice is a great insulator Reduce costly inventory spoilage Frost build-up on evaporator coil makes it less efficient Defrost control will determine when to stop cooling to allow the frost/ice build-up to thaw Decision is based either on Time schedule (defrost timer) Precise reading of the temperature or pressure (defrost controller) Manual Defrost Off Cycle Defrost Timed Off Cycle Defrost Heat Defrost Electrical Hot Gas Universal Defrost Timers (UDT) Works with multiple voltages Removes built up of ice and frost Easy to install Simple to program Part 9145-00 temp terminated Part 9045-00 time terminated Available as mechanism only without case Add M to end of part number 9145-00M Both mechanical and electronic controls are rated to UL873 commercial refrigeration standards Controls allow for a more precise termination of the defrost cycle based on a temperature or pressure value Manufactured products for the refrigeration industry since 1905 Controls are often called defrost timers because most popular method of defrosting equipment is based on a time schedule Easy to install and program even in retrofit applications The Paragon electronic defrost control matches traditional mechanical defrost controls and adds a number of advantages Multi-Voltage control is smart voltage Designed to fit into existing enclosures Certified to UL873 Standards Built-in power loss protection No pins or trippers to lose Manual defrost option LED status indication Real time clock Backlit display Easy Installation Certified to UL873 Switches rated at 30,000 cycles Last 16 years longer at 4 defrosts per day Initiate 15 minute manual defrost Lighted display 100 hours of power loss protection Simple Programming Designed to fit Paragon® enclosures Withstands most rigorous applications Wires to 120V AC, 208V AC or 230V AC Display has defrost time and duration System status indicators Real-time clock Why are these features important? Feature Benefit Multi-Voltage The universal voltage (120/208-240 VAC) requires no switch selection or different terminals Fits into existing enclosures There is no need to bend or replace conduit or run new wire. Replacement can be as easy as wire up, wire down on the same terminals Certified UL873 Designed specifically for use with refrigeration equipment and to refrigeration standards. Tested at 30,000 cycles vs. 6,000 Built in power-loss protection There are no batteries to buy or replace. All program and time settings are maintained for a minimum of 100 hours Why are these features important? Feature Benefit No pins or trippers to lose LCD Display gives indication of defrost start and stop time without pins that might slip or fall off Manual defrost 15 minute manual defrost is perfect for between cycles or system maintenance LED status Green LED for Defrost and Red for Refrigerate Real-time clock Intuitive clock display that reads clockwise and indicates time of day with a flashing cursor Backlit display No need for torches or flashlights in dark mechanical rooms UL873 sets specific functional and life cycle standards for equipment used in temperature regulation (refrigeration) UL873 insures the equipment will maintain safe and proper operation in commercial refrigeration environments Competitive products (timers) use a different standard UL917 is for clock-operated switches Paragon universal defrost products are the only multi-voltage defrost controls rated to UL873 standards Standard UL873 UL917 Life Cycle 30,000 Cycles 6,000 cycles Switch events-per-day 12 per day 4 per day Environment -30°F to 130°F (-34°C to 54°C) room temperature Load Requirements Maximum load (30A) allowed by contacts No load required Paragon® controls rated to UL873 are made to last five times longer than timers rated to UL917 standards Paragon Universal Defrost Timers are the only defrost timers engineered to refrigeration standards. 9145-00 Time Initiated Temperature or Pressure Terminated 9045-00 Time Initiated Time Terminated The Paragon 9145-00 is general purpose defrost control that can both Time Initiate/Time Terminate Time Initiate / Temperature or Pressure Terminate Most refrigeration applications do not need more than 30 Amps Part Number and Relay Information Relay Contacts SPDT NC Contact SPDT NO Contact SPST Common Contact Relay Rating 15 A resistive @ 120V AC to 240V AC ¼ HP @ 120V AC, ½ HP @ 208V AC to 240V AC 30 A resistive @ 120V AC to 240V AC 1 HP @ 120V AC 2 HP @ 208V AC to 240V AC 30 A resistive @ 120V AC to 240V AC 1 HP @ 120V AC 2 HP @ 208V AC to 240V AC Fan (Typical) Device Connection Compressor (Optional) Defrost Device (Typical) Compressor (Typical) Fan (Optional) The Paragon 9045-00 is a general purpose defrost control that is used for Time Initiate/Time Terminate only defrost cycles Part number and Relay Information Relay Contacts SPST #1 NC Contact SPST #2 Common Contact Relay Rating 30 A resistive @ 120V AC to 240V AC 1 HP @ 120V AC 2 HP @ 208V AC to 240V AC 30 A resistive @ 120V AC to 240V AC 1 HP @ 120V AC 2 HP @ 208V AC to 240V AC Device Connection Compressor (Typical) Defrost Device (Typical) Paragon Electrical Products are high quality time switches with sealed synchronous motors and metal gears Commercial Refrigerators store valuable products Refrigeration failures are costly in terms of lost product and business Paragon Defrost Timers are UL certified as refrigeration controls, not as time switches 40 Amps Time Initiated, Time Terminated All are 60 Hz, some 50 Hz units available Part Number Volts / 60 Hz Contact 2-4 Contact 3-N Application 8041-00 120 Closed Closed Electric Heat Defrosting 8041-20 208-240 Closed Closed Electric Heat Defrosting 8045-00 120 Closed None Electric, Hot Gas, Compressor 8045-20 208-240 Closed None Electric, Hot Gas, Compressor 8047-00 120 Open Closed Electric Heat Defrosting 8047-20 208-240 Open Closed Electric Heat Defrosting 40 Amp switches Time Initiated, Temperature or Pressure Terminated Provides three defrost cycles with mechanical timer Pump-down, defrost, and fan delay Part Volts / 60 Contact 3-N Contact 1-3 Content 2-4 Numbers Hz 8141-00 120 Closed Open Closed 8141-20 208-240 Closed Open Closed 8143-00 120 Open Closed Open 8143-20 208-240 Open Closed Open 8145-00 120 None Open Closed 8145-20 208-240 None Open Closed 1. 2. 3. 4. 5. 8145-20 8141-00 8145-00 8045-20 8045-00 Paragon® Intermatic / Grasslin (DTMV) Supco Old Manufacturers Precision Timer Co.
