UK:  Resource Data Management (RDM), leading HVACR control and remote monitoring solution provider, has announced two major product launches. The dmTouch, their colour HD touch screen management system front end now features a 10.1” screen. Further optimising the user experience the larger screen makes it even easier to monitor and control sites from one central point. The launch of the new screen is coupled with a number of software enhancements including faster browsing, optimised responsive interface, heightened graph performance, a new algorithm to further improve the data manager’s ability to highlight energy waste and enhanced language support for The Data Builder (TDB) - RDMs PLC software.

A key addition to their Intuitive range is the new Intuitive Transcritical Superpack Controller. Designed for the retail and industrial refrigeration markets the Intuitive Transcritical Superpack Controller is a versatile expandable controller intended for HT/LT CO2 Pack, Gas Cooler and HT/LT Oil monitoring and control. Each section is individually selectable and can be set to disabled if not required. The controller can be expanded using up to 10 Expansion Modules, consisting of the Intuitive Stepper Expansion or Intuitive IO Expansion module range. Building on the success of RDMs existing Transcritical software solutions the new Intuitive Transcritical Superpack controller has similar features and functions as the other controllers in the Intuitive Control range, with a number of key enhancements.

RDM Intuitive CO2 Transcritical Superpack Controller

For Gas Cooler and receiver control the Intuitive Transcritical Superpack controller heightens flexibility, giving users the ability to select between 0-10V, 4-20mA, 0-5v, 0.5-4.5v or 0.5-9.5v or stepper control for either or both of the two CO2 valves or any of the variable outputs, such as fan speed control. Furthermore this can be done using the same application software, allowing for the control of either HT/MT valve using one piece of hardware.

The new Intuitive Transcritical Superpack Controller software application is a single piece of software that can be configured to control and monitor the earlier mentioned applications. Using the additional Intuitive expansion boards will allow them to expand the number of control stages and/or introduce an oil management strategy, facilitating 5 sections of control and monitoring - Low Temperature compressor, High Temperature compressor, Gas Cooler, Oil for LT compressors, Oil for HT compressors. As a result the customer has the flexibility to quickly and easily build a solution that specifically meets their needs.

Toby Peters, Senior Group Managing Director, Dearman

When asked about his approach to product development Andrew Chandler said ''It may sound like common sense but when I started RDM, before we designed any products, I asked retailers an obvious, but often unasked question. What did they want? In doing so we gained their unique insight and confirmed our suspicions - they were frustrated at being locked in by proprietary systems and by products that despite their expense frequently required maintenance and came with a short life span. Our product development is driven with the customer at the heart of the process from start to finish. We are passionate about helping our customers be as energy efficient as possible, this begins with ensuring that the products they install are effective with a long life span and is why we offer a 5 year warranty on many of our products.

UK:  Toshiba Air Conditioning has introduced its long-awaited new flagship touchscreen air conditioning control solution.

The new 7in colour touchscreen controller offers unprecedented power and ease of use, enabling engineers and end users - even those unfamiliar with air conditioning - to control systems and optimise performance and indoor comfort.

With the ability to control up to 64 indoor units via a unique capacitive touchscreen, the new Toshiba controller marks a departure from conventional air conditioning controls based on slow-response resistive touchscreen technology.

It has a brilliantly clear colour display with pin-sharp graphical interface, providing lightning response to the operator’s touch commands. Unlike controllers from some other manufacturers, Toshiba’s new controller is not based on physical buttons but an intuitive touchscreen with icons, similar to a large smart phone.

According to Fraser Hymas, Toshiba’s control system manager, who headed the development of the new controller, a key element of the design brief was to make it simple and intuitive to use, without the need to refer to a manual, while enabling users to quickly access all functions with minimum layers to navigate.

In addition to primary control, alarm and scheduling functions, and quick access to units and parameters, the controller also acts as a web server, enabling it to host web pages.

The system offers a host of powerful functions that extend its use, with future developments including:

  • Energy monitoring with historical data backup, enabling long term trends to be analysed and managed;
  • Power meter pulse inputs for four air conditioning systems;​​
  • The ability to take account of input from an outside air sensor, to provide frost protection for buildings and optimised heating start and operation;
  • The ability for alarms to be reported automatically to building supervisors and designated service providers via email;
  • Potential to display floor plans for ease of unit location and control;
  • A supervisor touch screen to link multiple controllers, to accommodate larger systems with more than 64 indoor units.

David Dunn, Toshiba’s general manager, said: “The new system is a major advance in air conditioning control technology, not just in terms of what it can do, but the way it does it – and its sheer ease of use.

“The saying that ‘power is nothing without control’ is quite literally true. The whole design philosophy is to offer the most power functions available in the industry, while making it easy and a pleasure to use. After extensive testing, among both engineers and end users, we believe the new system achieves this – and opens up a new chapter in intuitive air conditioning control.”

UK:  Foodservice refrigeration specialist, Adande, has teamed up with ice cream equipment manufacturer, Carpigiani, to offer a range of dedicated dessert workstations. Designed as complete solutions for the preparation, production, storage and plating of professional artisan gelato product, the units are suitable for restaurants, hotels, fine dining, delicatessen and ice cream parlours. With a compact footprint of just 1100 mm width by 700 mm depth, the dessert stations are ideal for kitchens with limited floor space.

The workstations are available in a variety of configurations to meet desired capacity, including a layout which has Carpigiani units mounted on an Adande two drawer refrigerator. The worktop of the Adande unit can also accommodate additional equipment, such as a whipped cream machine.

Base mix ingredients are heated in the Boil 5 before the liquid is transferred to the Labo 8 12 E, where flavouring is added and the mix is stirred and chilled to – 8oC. The artisan gelato is then transferred into pans for pull down to the suitable storage temperature in the Adande® unit. For high volume operations, a pre-prepared UHT gelato mix may be poured directly into the Labo 8 12 E.

The ability to set precise and accurate temperatures in the Adande drawers has particular advantages for holding premium gelato. The bottom drawer of the Adande unit may be set at – 18oC, which is the optimum temperature for the longer term storage of gelato, eliminating the formation of ice crystals. The upper drawer may be set at – 14oC, during service, which is the perfect temperature for soft scoop service.

Alternatively, the lower drawer may be set at – 14oC for holding gelato during service, with the upper drawer set at + 4oC for the storage of complementary ingredients, such as fruit, toppings and sauces. The top drawer, at + 4oC, may also be used for chilling dessert plates and sundae glasses.

The Adande units are castor mounted, allowing them to be moved easily for cleaning regimes. The drawers and the gelato equipment each operate on a 13 Amp power supply and with no plumbing or water supply required installation is simple.

Carpigiani has recently opened a development kitchen at which chefs and ice cream operators can gain first hand experience of the dessert workstations. Appointments for demonstrations at the Carpigiani facility are available upon request.

Scott Duncan, Sales Director, Carpigiani, stated:

“Artisan gelato is a premium product, which requires holding at optimum storage and service temperatures. The unique technology of the Adande drawers helps maintain the gelato at the correct temperature, eliminating the formation of ice crystals for perfect product quality.”

Karl Hodgson, Sales Director, Adande, added:

 “Carpigian’s position as a world market leader is helping us to introduce the Adande® brand to new market sectors in the UK and on an international level.”
