SMC’s smart thermo-chillers for peace-of-mind this summer

SMC’s smart range of thermo-chillers come in an array of sizes and deliver on precise and accurate temperature ranges for peace-of-mind.

According to Guiomar Fernandez, product marketing manager for SMC ANZ, the company’s range of chillers offer proactive control, improved performance and are backed by world-class service.

“With things heating up in Australia and New Zealand, now is the perfect time to order a thermo-chiller for your plant. Industries making use of heat generating devices such as machine tooling, printing and packaging are at risk of high rejection rates, poor product quality and a lack of overall process reliability,” Guiomar said.

In terms of how it works, the recirculating fluid of the chiller removes the heat from the customer’s device. The heat is then removed from the fluid by an air-cooled (or water-cooled) refrigeration circuit. The coolant temperature stability is ±0.1°C within a set temperature range.

“Correct temperature control is vital for productivity,” said Guiomar. When properly sized and selected, a thermo-chiller improves the quality of the final product, protects valuable process equipment, and reduces costs.

SMC offers a variety of solutions ranging from our standard type to our basic types and our high-level type triple inverter type chillers that adapt to the variable heat and flow requirements, achieving substantial power savings of up to 53 per cent.

Answering to the call for Industry 4.0 solutions, SMC’s range of thermo-chillers put the power in its customers hands. “Thanks to proactive controls via a remote control, these units offer self-diagnosis readings so that customers can anticipate and easily manage any incidents.

Australian Refrigeration Association appoints new boss

The Australian Refrigeration Association (ARA) has named Ian Tuena as its new President, effective immediately.

Tuena takes over from outgoing President Tim Edwards, who had been in this role for five years. He will be supported by a revitalised Board.

In a statement, Tuena assured industry stakeholders that the ARA Board is committed to increasing the effectiveness the association.

“You know there is enormous potential for improvement in HVACR services in Australia.  We understand that we need for far greater participation by industry stakeholders in delivering the cost savings and emissions reduction made possible by natural refrigerant based technology. It is a challenge we are asking you to contribute to,” he said.

Tuena pointed to the words of Edwards: “The amendments to the Montreal Protocol call for global adoption of high efficiency, low emissions HVACR technology. Australia has the ability and need to lead this opportunity in the national interest…Now.”

Tuena added, “The simple fact is that natural refrigerant based technology has the potential to reduce the cost of HVACR services dramatically.  There is no longer a reason to delay.”

Operational analytics helps lower refrigeration costs

Monitoring 5,000 sites around the world, Danfoss, which specialises in producing refrigeration monitoring equipment, compressors, and controllers for grocery stores, required a solution that would help its customers view their operations at a presentation level, create reports on alarms and performance, and reduce energy costs.

 Backgrounds and challenges

Refrigeration consumes a major portion of a large grocery store’s electricity (up to 30 per cent in some cases), with the remainder consumed by HVAC equipment, lighting, and other utilities. The risk of asset failure – which can result in food loss, unplanned asset down time and maintenance call outs – needs to be added to this.

Retailers now operate in a market where the demand for frozen foods is increasing As such, they need to invest in large-scale refrigeration equipment. This has led to tight margins in an increasingly competitive market where assets are expected to perform constantly. Historically, supermarkets have accepted that the cost for high customer volume, regulatory compliance, and increasing energy costs are part of the business model.

Danfoss addressed these business challenges with an operational analytic solution provided by Bentley‘s Amulet that saves money, categorises and filters alarms, improves energy efficiency, and provides customers with peace of mind.


There were many key solutions that enabled Danfoss customers to manage their supermarkets more efficiently and to aid decision making. Central to these is the alarm management system that is in place to monitor food quality and energy efficiency along with a visualisation component to bring all of the information together in one platform.

Visualisation and reporting

The collection, organisation, and visualisation of operational information were important factors for Danfoss customers, as they allowed them to present a real-time visualisation of performance and current conditions, particularly focusing on generated alarms. Using the operational analytics solution, customers are able to view alarm counts and status; view and email performance reports on a daily, weekly, monthly, or annual basis; and create ad-hoc reports as required.

Alarm Management System

An underlying alarm management system means alarms based on a potential failure or a threat to an asset are automatically raised when a threshold has been reached. The difficulty here is identifying which alarms needed attention and which could be dismissed as a result of defrost cycles, or refrigerator doors being accidentally left open. Danfoss uses Bentley’s Amulet software to count repeated similar alarms and identify which are real and which are false, then notify the relevant people. Eliminating false alarms from the system significantly cuts costs by reducing needless callouts of maintenance engineers. Alarm histories can also be used against the asset, the fault, or the site to highlight patterns, such as a particular alarm occurring against the same asset consistently across multiple stores.

 HACCP reporting

Danfoss addresses regulatory food compliance with Hazard Analysis and Critical Control Points (HACCP) reports, a monitoring and reporting system that ensures food production and storage facilities are safe. Using Amulet for data collection and visualisation, HACCP reports show the average temperature during an hour (from typically four 15-minute intervals) of any asset containing food. These reports are displayed within Amulet’s dashboards and allow Danfoss and its customers to spot at a glance any differences in behavior in an asset’s temperature by using colour coded boxes to indicate whether an asset is operating above or below its normal level. These reports can display historical data to prove that measures are taken to ensure food safety.

Coupled with the Temperature Quality Index report, which displays the overall performance of an asset (within its set points), the reports bring a complete picture of asset performance in near to real-time.

Load shedding and set point management

Other functionality within Amulet include the addition of automated load shedding and set point management. Load shedding (or demand response) involves Amulet to help facilitate the automatic switching on/off of certain assets by interfacing directly with the hardware. This is to reduce energy consumption and receive financial incentives from power companies which need to reduce peak demand. This could include HVAC systems, store, and car park lighting.

From the Amulet dashboard, levels can be set that will send a signal to certain controllers, such as lighting zones, turning them off over a set period of time. Each level of load shedding can include any number of assets, from a few to all. These measures help reduce energy consumption while the initiative also encourages financial incentives from the energy provider.

Set point management automates corrections in hardware value points to ensure error control regulation of asset temperatures, switch status, and alarm values. This means that Amulet constantly checks values to specific hardware, like a switch or a set point, making sure they are correct. If a change occurs, or is made accidently by a third party, it can be entered into an audit trail and automatically corrected to the original value. This ensures continuity to the operational performance of the store and peace of mind, further reducing callouts and loss of stock. Set points and schedules can also be changed for an entire estate through one job.


Through the use of operational analytics, Danfoss has achieved complete visibility of its whole operation, including energy usage against external parameters like outside/inside temperatures and other factors. By monitoring these patterns for customers, Danfoss can regulate the environment in which its assets work. For example, refrigerators won’t need to work as hard if the temperature or humidity in the store is maintained at an optimum level.

Through Amulet, Danfoss is able to determine that substantial energy savings can be achieved and affect its customers’ bottom line. Key operational benefits included ensuring food safety and minimising food loss; reducing energy consumption; anticipating failure of refrigeration equipment; filtering, identifying, and notifying alerts and real service maintenance needs; prescriptive loadshedding for optimal power reduction; and prescriptive set point remapping when overriding settings.

The Amulet alarm management system allows Danfoss customers to monitor and track their assets and intervene when necessary if one triggers an alarm. With Amulet’s variety of specialised alarms such as threshold, percentage, or hold down, raised alarms have been filtered to only notify users of critical alarms, thus reducing false alarms and maintenance call outs.

Using Bentley’s Amulet operational analytics software enables Danfoss to increase its customers’ ROI by  eliminating false alarms, effectively monitoring energy usage, and provides them with levels of visibility that help them monitor performance more accurately and in a more timely fashion.


Vic Govt puts cold chain industry at risk, claims RWTA

The Refrigerated Warehouse & Transport Association of Australia (RWTA) has called on the Victorian Government to explain why it encouraged a business with a history of serial insolvency in Europe to enter the local market.

An investigation by the international Forensic and Risk Services company PKF has revealed NewCold’s European Directors have a history of insolvency associated with failed companies in the same industry.

RWTA Chairman David O’Brien called on the Victorian Government to disclose any subsidies or financial assistance offered to NewCold’s establishment in Victoria, and to explain what due diligence has taken place.

“Our own investigation found both of NewCold’s foreign Directors have been directors of companies that have gone into liquidation in the UK. How have they proved financial viability when there is a history of serial insolvency in Europe?” Mr O’Brien asked.

“This should have raised the alarm for any Australian business or Government considering entering a commercial relationship with this firm,” he said.

Mr O’Brien said he was extremely concerned that if NewCold decided to buy market share by price gouging, this would lead to job losses by destroying local players.

“The Premier needs to explain what data he relied upon to support his promise of the creation of 127 jobs in a business which is highly automated.”

The Australian cold storage industry is estimated to be worth about $6 billion, and is forecast to continue growing at around 2.5 per cent per annum.

New refrigeration technology for enahnced food safety

When it comes to maintain the highest levels of food safety, consistent and reliable refrigeration is a big part of the equation. 

At its 2015 Technical Roadshow, global refrigeration innovators Bitzer presented a new combination cooling system that caused quite a stir. Hailed as revolutionary and hungrily accepted by the industry, Bitzer’s new combination of the Evolution air-cooled condensing unit, plus PS Series evaporator with EVD-ice electronic valve driver boasts a three-months return on investment. 

Available fitted to the Buffalo Trident PS Series evaporator, the recently launched EVD-ice is the evolution of Carel’s electronic valve driver specifically designed to operate under extreme conditions, such as within the evaporator in a cold room. The EVD-ice can be easily connected to a supervisory system for external monitoring of operating conditions.

With the addition of Carel’s Ultracella technology, the user doesn’t even need to be in the cold room – messages, alarms and status display are all accessible from outside the room. 

Plus, the Ultracap module is an additional option for users needing an IP65 rated solution, with over-molding completely sealing the device. 

The short pull-down times and system performance result in improved food quality and in turn further cost and efficiency savings for food manufacturers.
