MHIAA hosted training day for Kirby sales team

Kirby NSW sales staff were pleased to attend a recent Mitsubishi Heavy Industries Air-Conditioners Australia (MHIAA) training and development meeting at the manufacturer's Innovation Park, a new training facility at Regents Park.

Designed to strengthen awareness of MHIAA’s wide range of product offerings and product training opportunities, Kirby staff were able to view the capabilities of the facility and were provided with more information on the MHI product range. The training session featured presentations from various staff, including members from the MHIAA R&D Department, Technical Sales Department and other business areas.

Kirby Australia is one of MHIAA’s long-standing key customer groups and has been on a same growth journey that MHIAA has been on over the years. The training day was a resounding success for both Kirby and MHIAA and we look forward to further partnership opportunities.

Kirby launch a next generation of evaporators

Designed in Australia, the Kirby® Guardian range represents the next-generation in evaporators incorporating advanced engineering and innovative features to meet the future requirements of the refrigeration industry.

The range is specifically designed for next-generation, low GWP refrigerants, including R450A, R448A, R449A and R513A.

A key feature of the Kirby® Guardian range is the advanced Series 9 coil design that produces additional capacity, more stable room conditions, reduced frost accumulation and more efficient air defrost, through the use of sine wave technology and a larger surface area. The result is greater efficiencies and lower cost of ownership.

Kirby® Guardian’s efficient design is further supported by Ziehl-Abegg owlet fan blade technology that achieves larger air volumes, optimal flow properties and improved noise ratings. Easy access panels and a fully reversible drain pan complete an exciting new range that is everything you have come to trust in Kirby.

Further extensions in the Kirby® Guardian range are soon to be released, including Kirby® Guardian Ultra, Kirby® Guardian Ready Connect and Kirby® Guardian Ecocool, with models to suit a variety of specialised applications.

New HFO refrigerants available from Kirby

Kirby now has available HFOs designed to replace R404A, R507, R123 and R134a.

Log into your smartaccess account to download the comprehensive Refrigerant Fact Sheets and contact your local Kirby branch for available cylinder size options.  

R452A is a non-ozone depleting, non-flammable HFO refrigerant blend designed as a lower GWP alternative to R404A and R507 in low and medium temperature applications. R452A closely matches R404A thermodynamic properties and performance and offers a lower compressor discharge temperature. This refrigerant is primarily used for transport refrigerated vehicles as they require a safe, non-flammable and low toxicity refrigerant, with the ability to work efficiently under a wide range of ambient conditions.

• R452A should only be liquid charged into a system to ensure correct refrigerant composition and system performance
• Non-flammable, A1 safety classification
• POE oil
• Used as a retrofit or new installation
• Is used in low and medium temperature applications

R1233zd is a non-ozone depleting, non-flammable HFO refrigerant, produced as a replacement for R123. It is primarily used in low to negative pressure centrifugal chillers, with better performance and improved efficiency compared to R123.  R1233zd is suitable for new equipment and NOT suitable for retrofit applications. For optimal performance, it is recommended to use valves and fittings with plastic sealing washers. Avoid using fibre washers as leaks may occur.

• Non-flammable, A1 safety classification
• Mineral oil (specific)
• Ultra-low GWP 1
• Innovative single component HFO

R1234ze is a HFO refrigerant designed as a low GWP alternative to R134a. Used in chillers, commercial air conditioning and as the secondary refrigerant in CO2 cascade systems in commercial refrigeration. Due to the flammability, it is essential to check equipment compatibility.  R1234ze Should only be used in systems specifically designed for R1234ze.

• Ultra-low GWP < 1
• Compressors must be charged with modified polyolester oils (check OEM guidelines)
• Not suitable for use in retrofit applications
• Liquid or vapour charge

Breakthrough: Gel Clear tablets reduce maintenance costs

A recent Sauermann Australasia Gel Clear tablet trial was conducted at a store located in Sydney, NSW. The store has a problematic history of water leaks on the store trading floor.

The store is located above a railway station meaning there is no drainage through the concrete slab underneath each refrigerated case like most regular stores. As a result, condensate pumps have been installed under each of the refrigerated cases to discharge all the condensate water into common tundishes in the ceiling space.

Each of the condensate pumps at the store regularly formed biofilms stemming from their respective refrigerated case. If the refrigerated case and subsequent condensate pump was not proactively cleaned, this biofilm evolved into thick sludge. The sludge caused the condensate pumps to block, stop operating and resulted in water leaks.

A Sauermann Australasia Gel Clear trial was conducted with the 36 medium temperature cases on the trading floor. It was agreed only 5 of the worst cases would be trialled initially with Gel Clear tablets.

Prior to the trial the store had logged an average of 11 refrigeration service calls a month, costing an average $350 each, for the 24 month period between 2016 and 2018. During the 6 month trial period, there was a 95% reduction in water leaks as a result of the installation of Gel Clear tablets.

The trial results confirm that the Gel Clear product eliminated the majority of issues related to condensation pump failure and leaks. The service call history was drastically reduced from an average 11 calls per month ($4000 p/m) with the use of the Sauermann Australasia Gel Clear tablets. It is recommended that the Gel Clear tablets be installed as part of each store’s case clean schedule.

In this trial, the maintenance call costs could have been reduced by an estimated $40K per annum had the tablets been applied to all refrigeration cases. Further, based on the trial it is recommended the Gel Clear tablets be reinstalled every 6 months in each of the refrigerated cases.

Whilst the trial was conducted in a problematic store that was fitted with condensate pumps, the tablets are just as effective in reducing biofilms in stores with standard drainage systems not only in commercial refrigeration, but other air conditioning applications such as air handling units, split systems fan coil units.
