  1. Presscon Network &Pressnet Software Refrigeration HVAC control & monitor system Click left mouse button to advance, “back” to return

  2. What is Presscon Network? A Modular, networked refrigeration and air conditioning control system. Which is: Reliable, Powerful & Expandable Ideal for Supermarkets Cost effective Fully supported with Pressnet software

  3. First released 1992- continual development since .... Used in Australia by Woolworths, Coles, Bi-Lo, Franklins, IGA & many independents supermarket operators Used by majority of refrigeration companies in Australia. Used by Tesco, Carrefour & others in China & Indonesia Over 1000 sites Fully supported by Phasefale: -design -training

  4. Pressnet Software Pressnet; Windows based local and remote access software for Presscon Colorful animated bitmaps and store layouts easy to use, Full control and data access Internet and telephone connection

  5. Normal Alarm Pressnet Graphing • UNIQUE- Colour coded temperature trace shows system status • Graphs to incredible 1 minute precision • allows quick and easy trouble-shooting of problems • multi trace graphs also available

  6. Controller, card list is automatically found on connection to site. Graphic setup is a simple drag & drop arrangement. Channel icons are colour coded. Detailed information is displayed on hover Edit channel Select remote cards[local cards is used to save setup to local PC] Select controller Select site Pressnet- Card list

  7. Case Control- decentralized option Solenoid, Electronic Suction & Expansion control options 2 complete systems per board :control/defrost/alarm Case monitor can supervise & program 99 case controls 4 way expansion board for solenoids, heaters, fans, lights, antisweat etc. Up to 8 ouptuts per control 11 inputs per case control

  8. Multi Controller • Powerful controller withmultiple control types • Main Types: Rack Control • Temp/Alarm/Defrost (Syscon) • DDC for HVAC • New 99 Channel lighting control “LTC”

  9. Multi- Rack Controller 4 Suction & 4 discharge groups 8 compressors per rack 8 fans per condenser Analog suction & discharge Gas Leak detection (6x) Power Monitoring (4x) Humidity/ Anti Sweat control (2x) most functions of singlerack controller

  10. System Controller(centralized option) 20 system channels each with up to 10 temperature sensors 8 Auxiliary channels for system faults etc. 4 lines x 20 character backlit LCD off cycle, electric or no defrost for control, alarm, display & defrost termination

  11. Air Conditioning Control Share common databus & communications controls 8 major plant- each has: 4x heat and 4x cooling stage Time & event based scheduling Humidity control of plant Economizer function & other energy saving features

  12. Power Monitor In conjunction with Pressnet Software allows detailed analysis of power consumption High Precision Class 1 3 phase Scales to any power level with CT Graphing & Datalogging allows peak & consumption figures

  13. Power Monitor- Analyses Use Pressnet software to;download data to Excel and analyze power consumption. Pressnet can calculate Average, Minimum , Maximum etc power over a nominated timeperiod.

  14. Pressure Transducers All stainless steel, electrically robust & mechanically tough LP version for 0-100psi HP version 0-500 psi 12V supply 15mA Voltage output 1-6V Absolute version for ammonia

  15. Temperature Sensors 0.2°Celsius precision Fully water & immersion proof most reliable sensors in the industry High temperature version for discharge lines (“H” type) 6 meter lead, H=1.5m silicone

  16. Refrigerant Leak Monitor Detects all common HCFC refrigerants Up to 6 channels – monitor cabinets and plant room. On multi rack controller

  17. Sensor Input Cards 32 Channels input cards First 8 channels used for pressure trans-ducers & all input types 32 channel for temperature & switch inputs - more cost effective & compact both have 10 bit precision pluggable connectors

  18. Relay Output Cards 8 SPDT Relays each 5 A 240VAC 2 0-10V Analogue outputs LED status indicators Over-ride switch for each output Ultra reliable & immune from electrical interference 12V supply
