Products Temperature, humidity & moisture control Keeping the wine fine during storage All-in-one solution


Storing wines for extended peri- ods has traditionally been in caves or underground cellars, simply due to the fact that these environments naturally maintain a steady temperature over pro- longed periods. In addition to temperature, humidity levels can also affect stored bottled wine. For example, if humidity is too high then it can seep into the cork causing bacterial contami- nation which could ruin the wine, whereas if humidity is too low over time, wine can be lost through the cork, reducing value. Optimum temperature and humidity conditions are found in naturally occurring caves or underground cellars, but these environments are a limited resource. Building underground wine storage facilities is expen- sive, so the solution has been to build above ground. Replicating the ideal wine storage conditions found in natural caves requires careful planning and control. Even though a steady, opti- mum temperature can be con- trolled with relative ease, when it comes to maintaining a steady


level of humidity, things become more complex.


Natural caves or artificial underground structures maintain constant humidity because equi- librium is reached between areas of high humidity and low humid- ity. In contrast, any changes in the humidity of the air outside an above ground warehouse will quickly affect the warehouse humidity levels. Adding mois- ture to increase humidity levels in an area can be achieved through the use of suitable spray nozzles which provide a very finely atomised spray. However, optimum conditions depend on how quickly humidity changes can be detected and acted upon by an automated system. Also, there is no effective way to remove moisture from a large area once it has been humidified, it is just a case of waiting for the moisture to disperse naturally. Despite the problems, effective humidification systems can be achieved using quality spray noz- zles, and the knowledge of expe- rienced engineers who understand humidity variables.


For example, one wine logis- tics company has successfully converted old aircraft hangers into purpose-built facilities in the UK where fine, valuable wines from around the world are stored. Piping specialist Regent Mechanical was chosen to under- take the installation of the system using BETE XA series Air Atomising nozzles for the humid- ity control system.


A series of 16 XA PR atomisers were installed in 4 pods of 4 and because the warehouse was so large it was divided into 4 zones, each with its own climate control system. The individual zones have their own humidifying pod which is calibrated and set to deliver the correct levels of water to maintain optimum humidity levels. Extensive monitoring of humidity levels throughout the day and night needed to be undertaken to ensure that the on/off cycles were correctly set but, the final result is a ware- house with a steady temperature and humidity.

Turck has added the TS530 tempera- ture sensor to its range. Featuring an integrated resistance temperature detector (RTD), the sensor combines the display, process connection and RTD all in a single part for fast and reli- able performance.


Simple, push-button programming and large LEDs ensure easy operation, while the rotatable display, which can turn up to 340˚, allows for flexible viewing in the field. The sensor also sends feedback to a PLC, allowing operators to monitor measurement per- formance from virtually any location. The design of the sensor means they can be mounted directly to a tank or pipe with no mounting bracket required. Turck
