Ultra Refrigeration has completed one of the first installations of the new Bacharach MGS-400 Series leak detection system for CO2 equipment. Steve Gatenby, sales support manager at Climalife UK, talks us through the project.
Whether for safety, to maintain optimal energy efficiency, minimise the cost of refrigerant loss, or to comply with legislation such as F-Gas, there have never been so many compelling reasons to find leaks and fix them early and quickly.
Modern refrigeration systems are designed to be efficient and leak free, but improper installation, inadvertent damage or mechanical wear can result in potentially hazardous refrigerant leaks, which is some cases, could also be flammable.
Lincoln Co-op is a new flagship concept store for the Lincolnshire Co-op Group and required a leak detection system to be fitted to its CO2 compressor pack in order to indicate the presence of CO2 levels which exceed the current safe levels, and to indicate a leak.
Ultra Refrigeration, who work closely with the Lincolnshire Co-op Group, contacted Climalife UK to see which leak detection product would be most suited to this installation. The Bacharach MGS-400 series was chosen as it is the latest technological advance in leak detection, and utilises Bluetooth communications for the set-up process, making it quick and easy to be installed at site.
The MGS400 series is the latest product range from Bacharach and is a complete leak detection solution designed specifically for safety and F-Gas compliance in refrigeration applications. It comprises of three gas detectors, MGS-410, MGS-450 and MGS-460, an 8-channel controller, MGS408, and a smartphone app, connectable to the detectors & controller via Bluetooth.
The MGS410 detector requires connection to the MGS-408 controller, or a BMS/BAS via Modbus. The MGS450 and 460 are standalone units, but can be connected to the MGS-408 or a BMS/BAS.
All the gas detectors offer integrated audio and visual alarms which comply with safety regulations and maintain performance in temperatures as cold as -40°F (-40°C).
The MGS-400 series refrigerant detectors can be connected to a smart phone (Android or iOS) via Bluetooth, using the Bacharach MGS-400 app. The app makes commissioning and maintenance intuitive and requires no special tools or training in order to set up the alarm behaviour or thresholds. It also gives the user a real time reading of the PPM levels of the refrigerant being detected.
The MGS-408 controller can have a maximum of 8 detectors connected to it, in any combination of MGS-410, 450 and 460, allowing the centralised monitoring of several gas detection points.
The detector was fitted to the CO2 compressor pack, manufactured by Ultra Refrigeration. The detector was very easy to install and only required a few electrical connections including power and outputs. Set up was simple via Bluetooth and the MGS-400 app.
Anthony Lomas, operations director at Ultra Refrigeration, said: “We’ve just finished set-up and commissioning of our second device which has now become a standard on our CO2 packs for Lincolnshire Co-op Group.
“The integrated alarm provides a reliable warning for persons entering the plant room should CO2 be present, and connection to the site’s RDM DM Touch means we can remotely monitor the system for pending failures due to leaks, even if very small and not posing a safety issue.
“Set-up using the Bluetooth connection and iPhone app was a breeze and simplified the whole process. Aside from learning how to make the initial connection, there was no need to consult the installation manual or to navigate a complicated parameter list.”
Climalife UK sells a range of fixed leak detectors from Bacharach to suit most refrigerants and systems. Bacharach are specialists in the manufacture of products that detect, measure and monitor gases with both portable and fixed instruments.
