The coolest developments in temperature control

The coolest developments in temperature control

September saw the return of the Temperature Controlled Storage and Distribution Show, which offered an opportunity for the industry to show new products. This month we look at some of the latest refrigeration equipment available for fleet operators.

The Temperature Controlled Storage and Distribution Show was staged at Exec on the East of England Showground site near Peterborough and provided an opportunity for the latest products to be showcased.

This included the new ENVIRO-litre range of refrigerated van conversions from the Leeds-based GRP Group, a well-known refrigerated vehicle builder and converter.

In launching the new ENVIRO-litre range, GRP says it has been able to reduce the environmental impact of both producing and operating the vehicles.

This has been achieved by combining traditional laminate conversion techniques with more modern material productions and conversion that weighs up to 25% less than other competitive conversions. This results in lower fuel consumption and carbon dioxide emissions for the vehicle, claim the firm.

In addition GRP saya that the principal raw materials used in the conversion are free from heavy metals and are classified as non-carcinogenic.

The new conversions will be sold alongside GRP’s existing CORE-tecc conversions, based on the traditional wet lay laminate process.


Advanced and accurate approach 
Telematics systems allow for more accurate monitoring of controlled temperature goods than ever before and many refrigeration systems now incorporate monitoring either as part of the system or an option.


The development of radio frequency (RF) devices also means that it is possible to monitor temperatures without cutting holes in the vital insulation layers to run cabling. RF devices can transmit data over short distances using a battery-powered, built-in transmitter, which can be monitored in a vehicle cab or, using telematics, remotely, to ensure that the fridge temperatures does not move outside the required parameters.

Hanwell Instruments recently launched a new compact RF temperature-monitoring device called the RFBug. Hanwell says it is the smallest device of its kind, measuring 105mm x 65mm x 19mm and weighs 100g without battery. The RFBug monitors temperature and humidity and will sound an alert if either moves outside pre-set limits. The company says that the system can transmit data to a local PC for analysis of the data. A built-in memory can store up to 100,000 readings. Two AAA batteries should last up to two years, providing readings at three-minute intervals, while the RFBug is said to use simple software and is compliant with RoHS and WEEE EU directives.
