Time for change? – Digital technology for refrigeration service engineers
With 2018 being a pivotal year regarding many changes in the availability of certain refrigerants and the move towards low-GWP products, many companies will be looking towards the requirements for new service tools and equipment to ensure that their engineers are prepared and ready for products such as R32, R448A & other low-GWP refrigerants.
The other factor that will be making companies look towards low-GWP products is the reduced availability, subsequent high cost, and eventual phase-down of products such as R404A, R410A, and R134A which have been the mainstay of many refrigeration and AC systems. To meet the dead-line set by the EU’s F-gases regulations that stipulates the end of use of fluorinated hydrocarbons with high global warming potential (GWP) by the year 2020, and with many customers looking to accelerate the switchover to already available, more environmentally friendly refrigerants to avoid delivery difficulties, the curtain is coming down on the first HFCs. But will the end be a short sharp shock – or drag on like the CFC phase-out?
However, this may be easier said than done, what will an end customer do? He contacts his refrigeration system engineer and expects an alternative solution. Or better still the maintenance or service technician proactively makes his customer aware of his systems that will require new refrigerants. For example, his advice may be to retrofit the plant to a mid-term solution, or even better, to invest in a long-term solution right away. In the mid-term this means that often using simple means, an existing plant can be adapted, by retrofitting to a different refrigerant if possible – whose lifespan may also be limited by forthcoming regulations. Long-term means investing possibly in complete new systems, to subsequently no longer be affected by the F-gases regulation. This is the case with the new HFO substances, and was always thus with the natural refrigerants.
In practice, a retrofit will certainly be the most pragmatic approach for existing systems in many cases. However, that doesn’t make life easy for the maintenance engineer. Because today’s refrigerant industry offers a wide range of alternatives, they all have “their” solution at the ready but which one is right?
A decision is needed. Every refrigeration system engineer makes the best he can for the benefit of the customer. And whichever solution is chosen in the end, the update of the system then takes place to make it suitable for the chosen new refrigerant. Evacuation of any old refrigerant, compressor oil change, new control and measurement components, possibly a change of gasket materials, maybe a different compressor, fill the new refrigerant, and then run the system and adjust the settings.
One thing that is a certainty in an uncertain world, is that changing to a digital manifold as a service tool makes the process of refrigerant changes and subsequent commissioning and set-up a simple task. It no longer makes any difference which alternative refrigerant you’ve chosen. Up to 60 refrigerants are stored in the Test 550 or 557 digital manifolds, and with the added user benefit of smart connection via Bluetooth to a smartphone or tablet that allows engineers to update the Test manifolds as new refrigerants.
Another benefit of the Bluetooth link from the Test 550 or 557 digital manifold to the free Test refrigeration app is that it allows the engineer a fast and effective way to document the performance of the system directly whilst ‘on-site’, with the app display allowing readings of evaporator and condenser temperatures and pressures, and direct display of superheat and sub cooling values as well.
The app is available for both Android and iOS. Once the app is installed, a connection between the manifold and your smartphone/tablet can be established via Bluetooth.
With the increased cost of refrigerants, it is also imperative that engineers ensure that a complete pressure test with nitrogen is performed prior to any re-gassing, and again the Test manifolds ensure optimum testing by having a temperature compensated pressure test function that will show the start/end/delta pressure during the leak test and the total length of time that the leak test was performed. The temperature compensation ensures that any fluctuation in ambient temperatures are measured during the pressure test, and that no error due to this ambient fluctuation will show in the pressure readings. Again, these test results can be downloaded via Bluetooth to the app and a pre-configured report generated for the client.
So, in summary, depending upon your choice of future refrigerants, your service engineer’s vehicle may still have several different refrigerant cylinders on board – but you might only need one manifold. It couldn’t be easier!

Automated temperature monitoring in the Secret Smokehouse
All food producers must adhere to numerous regulations, and standards, with the end goal of ensuring the quality and safety of food. A key requirement for HACCP and food safety is continuous temperature m
onitoring. This involves recording and documenting the temperatures of all fridges, freezers and areas where climate sensitive foods are stored.
The Secret Smokehouse supply high quality smoked fish to some of the UK’s top Michelin star chefs and restaurants, as well as Delhi’s and a small group of direct customers. A small, but rapidly growing operation, they were actually nominated for ‘Best Producer’ in the Observer Food Monthly Awards 2017, and are proud to work with the likes of Jamie Oliver, Claude Bosi and the Clove Club in Shoreditch, to name a few.
The challenge.
As a small-scale food producer, the EHO (Environmental Health Organisation) expect the business to be able to demonstrate how it manages HACCP and records what it does to make the food safe. A major part of this, is documentation of temperature values to show produce is stored correctly. The EHO also favour a method where they are able to see the checks have been done, without having to visit the premises physically each time.
Before implementing testo Saveris 2, Secret Smokehouse were checking temperature using a combination of spot checks with a thermometer and reading the fridge/freezer thermostats. This means all checks are done so manually, and recorded with a pen and paper. Also, as they have since discovered, fridge thermostats aren’t always completely accurate. When opening the fridge or freezer door, the temperature reading on the thermostat dropped very quickly. This would indicate the produce was at a high risk of not being stored correctly. The smokehouse suspected this might not reflect the true temperature drop, so wanted to explore installing a monitoring system to prove this.
The other issue with the previous methodology, was if there was an issue with a temperature deviation (from a loss of power or freezer door being left open for example), they wouldn’t know until the next check. This could be too late to save valuable stock.
This drove Max Bergius, owner of Secret Smokehouse, to explore options to simplify and, if possible, automate their temperature control. Research lead Max to Testo Saveris 2, with the standout advantages of using cloud software to demonstrate due diligence and the removal of taking measurements manually.
The solution.
Testo’s Saveris 2 is an automated temperature monitoring system that stores all measurement data in one central place. Multiple measuring points can be incorporated into the same system, meaning all fridges, freezers and storage locations are monitored simultaneously, with measurement data being transported directly to the cloud. This removes the need to collect data manually and the results can then be accessed by the dedicated person remotely, via PC, tablet or smartphone. This means there is no longer a potential for readings to go missing.
Testo Saveris 2 loggers are used to monitor temperature in refrigerators and a freezer.
In the Secret Smokehouse’s case, they are using a total of 4 loggers to monitor their 3 fridges and 1 freezer. They also use the probe from one of their loggers to spot check on each fish, once smoked. Speaking to Harri Walters, production manager at Secret Smokehouse, he explained how with the introduction of testo Saveris 2, they are already reaping the benefits of an automated monitoring system:
Before introducing a testo Saveris 2 monitoring system, Harri would need to perform a series of temperature spot checks; once in the morning and once at closing. Harri estimates that by removing the need to check the fridges manually, they save 5-10 minutes per day. Admittedly, as a relatively small operation this time saving isn’t enormous, however, with only 2 employees in the business, any additional time is precious. And as a former chef, Harri knows all too well that in a high-pressure kitchen environment these time restraints are only amplified. In either case, Harri concluded, the last thing you need is additional tasks to worry about.
The biggest advantage by far is not having to worry about it as much. As mentioned previously, the EHO (Environmental Health Organisation) expect small food businesses to be able to demonstrate how they manage and records what measures they take to ensure their food is safe. Testo’s Saveris 2 provides a straight forward way of proving due diligence and that they are monitoring temperature effectively.
Testo Saveris 2 – The advantages.
Saves Time – Without an automated system in place, an employee has to go through the whole site manually, checking each location. By automating this, all data is sent directly to cloud storage, allowing you / your employee additional time to focus on other important jobs. Reports are also collated and sent to you automatically so you don’t have to lift a finger.
Saves Money – employing a temperature monitoring system can save you money in the long run, on wasted stock, product recalls etc. If there is a potential problem, thanks to the alarm function, you will be notified immediately, before it is too late.
Secure and accessible remotely – all data is stored in one central, secure place. Reports can be sent directly to you via email, so you don’t need to waste time checking each individual logger (or even going to the site for that matter). Alarms can be set to send via email, SMS or App.
User friendly – some monitoring systems require time-consuming installation and maintenance but with a wireless system such as testo’s Saveris 2 it is very simple to get set up and started.
“With the Testo system our temperature monitoring is practically effortless, and we no longer need to worry. All kitchens should invest; as a chef or food professional the last thing you need is additional tasks.
Testo have been very friendly and professional during installation and throughout – a pleasure to deal with.”
Harri Walters – Production Manager, Secret Smokehouse
