Blast – it’s getting bigger
Essentials for cost and energy efficiency
INCREASED ENERGY efficiency and productivity are high on the priority list of any company in the refrigeration and cold storage business. But these businesses also want solutions that are easy to install, cost effective and, above all, innovative – and this is where the range, manufactured by Stonegate Instruments, comes into its own.
Stonegate is one of the UK’s leaders in refrigeration and temperature control systems with a collection of products that are not only capable of cutting energy bills but can also reduce carbon emissions.
Monitoring and controlling
the conditions within a cold store to ensure that products are kept at the correct temperature is essential.
PRECISION HAS launched an energy efficient blast chiller freezer with a product loading of up to 40kg that can be plugged into a standard 13amp socket.
Building on the popularity of the 35kg model, Precision has introduced several design changes to increase efficiency and improve food holding quality. “Our new blast chiller freezer sets new standards in the market by coping with up to 40kg of product while still operating from at 13 amp socket,” says Nick Williams, managing director of Precision.
A new racking/shelving guard combined with upgraded software allows even more airflow to circulate around the product increasing the speed of chilling.
A smart refrigeration system ensures minimal gas charge and maximum performance while microprocessor- controlled, variable speed fans ensure fast blast chilling throughout the cabinet.
Of all stainless steel construction, the cabinet itself has been re-engineered with an improved condenser cover and door to increase the airflow and give a modern look.
The standard 90 minute blast cycle is started by pressing two buttons. The chill or freeze cycle can be controlled by programmed timer or by food probe. It also offers a choice of ‘soft chill’ or ‘hard chill’ modes, for different food types and consistencies.

Stonegate has recognised this and its answer is the compact digital thermometer. These thermometers, designed to be used with the Stonegate thermistor probe, can be hand-held or wall-mounted at the entrance to the cold store or near equipment that needs to be monitored, operating over a range of plus or minus 50°C and constantly display the temperature on their brightly-lit screens. Audio and visual alarms instantly alert staff to variants in temperature.
Being able to control and maintain temperature in this way is invaluable, since research has shown that every 1°C saved can reduce a company’s energy bill by up to 3%.
Another cost-effective technology from the Stonegate range is the door open alarm. This simple, effective solution indicates when a refrigerator door has been left open for an extended period of time. The alarm uses a highly-lit, bright, multi-coloured LED screen which displays the status. It also incorporates a clever speech warning – the alarm’s main feature – which has an increasing volume to alert nearby personnel who can immediately respond. Action can be taken, thus avoiding any possible rise in temperature. In order to ensure systems are operating efficiently and at their most cost effective, Stonegate has developed the cold room logger. Used for temperature analysis, these data loggers measure not only temperature but also door contacts and current transducers.
They work by storing data at regular intervals to the memory, which can then be accessed at any time using a USB connection to a laptop before being easily interpreted.
A Transducer Trip Module can also save energy, improve efficiency and reduce the risk of compressor failure. Used in conjunction with moisture level transducers to monitor moisture content, it ultimately prevents early refrigeration equipment failure.
Stonegate’s innovative and easy-to-install products are now being used by electrical contractors, refrigeration equipment wholesalers and major supermarkets, as well as food service and processing plants.
