Cold rooms are in many ways like air conditioning systems except that it keeps food frozen or chilled. Frozen food is kept at -20 deg C typically. When power failure occurs, the temperature takes a long time to rise. Sometimes it takes half a day to rise to -10 deg C. In such instances temperature monitoring of the frozen meat may not be critical. Monitoring of the refrigeration equipment may be important as repair of the equipment can be a full day's job or longer.
For chilled produce like fresh flowers, specialty vegetables, fresh fish, fresh milk need to be kept in very controlled temperature environment. Deviation outside the acceptable temperature range will damage the produce. There is a know case here that a fresh food suppler discovered in the morning that all his stocks in the chiller room were damaged due to a faulty thermostat. The temperature falls to -8 deg C and "froze cooked" all the specialty vegetables. The damage done was USD 40,000/-
Sometimes, cold room doors are inadvertently left opened for long hours leaving the compressors to run continuously, pumping up utilities bills. WT 9001 will be a useful tool for the owner as well as the cold room supplier to monitor the product (fresh food) and refrigeration equipment. As can be seen, failure in any component in the equipment can cause losses to businesses.
WT 9001 can be installed at key installation and in unmanned locations to monitor : compressor pressure and temperature, condenser fan motor overload, evaporator fan motor overload, room temperature, door contacts, etc. Technical crews are immediately notified via SMS with clear description of fault and location of such failures.
They can also log into WT 9001 from a remote location to view the details of the problem so that they can respond with the right tools and parts. WT 9001 is flexible enough to direct different types of problem to the correct people. Monitoring can also be done over the Internet.
WT 9001 SMS alert devices which able to sends information/ status of a system to 20 users. (to mobile phone/software/server/capital) by SMS if any emergency happen.
The engineer also cans SMS from his mobile phone to turn on/off or reset the compressor pressure, ELCB/MCB and On/OFF lightning, air conditioner, fan motor.
WT9001 design and provide complete solution including hardware and software communication platforms, user friendly interface and a variety of special sensors.
