MSC ADDS OVER 5,000 STAR COOL CA UNITS TO FURTHER EXPAND ITS REEFER FLEET

Controlled Atmosphere technology slows the ripening of fruit and thus extend its shelf-life. By integrating the Star Cool refrigeration unit directly into the container, MSC is providing a more efficient solution without sacrificing strength or reliability.



People around the world are increasingly seeking a healthy lifestyle. Fresh fruit and vegetables are an important contributor, with the added benefit of a delicious taste.
As a result, the total global fruit trade market has grown by an average of 40% over the last ten years to 63 million tons, underpinned by Asia’s rapidly expanding middle classes, according to data from Fruit & Vegetable Facts.
MSC is a world leader in meeting that demand through its reefer cargo services. With over 1.8 million TEU annual reefer shipments in 2019, it is continually investing in the best-refrigerated transport solutions for all kinds of fruit and vegetables – and is now adding over 5,000 Star Cool units using Controlled Atmosphere (CA) technology.
Effective and efficient
CA is an active process to regulate atmosphere composition to extend the shelf-life, maintain the appearance, freshness and quality of perishable products such as stone fruit, apple, avocado, lettuce and persimmon. It does this by slowing the natural ripening process by reducing oxygen concentration and increasing the carbon dioxide.
Star Cool CA is based on the concept of an effective, simple and low-energy CA system that is built into the Star Cool Integrated Reefer. By integrating the refrigeration unit directly into the container box, MSC can offer an advanced solution that weighs less, carries more and consumes less energy, without sacrificing strength or reliability. In a conventional reefer, there is a high level of heat transfer via the double frames of machinery and container. Integrating Star Cool eliminates this thermal bridging, resulting in reduced heat leakage and improved energy efficiency.
MSC is also installing StarConomy control software on its entire Star Cool fleet, reducing energy consumption by up to 50%. With investments like this, MSC ensures its reefer fleet is up-to-date and sustainable, and ready for any forthcoming regulatory changes around emissions.
Helping fruits shippers reach new destinations
Not only MSC has responded to the booming market for fresh fruit and vegetables by continuously investing in reefer technologies but the company also plays a key role in maximising the shelf-life and quality of the agricultural produce it transports, thus helping its customers expand their business by bringing cargo to distant markets in perfect condition.

Honeywell announces new alternative to R134a refrigerant

Honeywell has revealed details of its new lower GWP refrigerant replacement for R134a in new medium temperature commercial refrigeration, chillers and heat pumps. 

Solstice N15, designated R515B by ASHRAE, is an A1 non-flammable refrigerant blend with a GWP of just 293 under AR4. 
A blend of R1234ze (91.1%) and R227ea (8.9%), R515B is said to have zero glide and low discharge temperatures with an efficiency to match R134a. 
R515B is designed for new equipment and is not a retrofit product for existing systems. Honeywell lists its applications as remote condensing units, supermarket multiplex systems, stand-alone units, medium temperature side of cascade systems, flooded systems and high ambient air conditioning.
It has already been approved for use by Danfoss in its new Turbocor TG490 compressor for air- and water-cooled chiller applications.
The blend’s component R227ea is little used as a refrigerant due to its very high GWP of 3220. It is used here in a small proportion to suppress the mild flammability of the low GWP HFO R1234ze. While R1234ze is classified as an A2L refrigerant, it is only flammable above 30°C. EN 378, which is harmonised with the EU PED directive, does not recognise R1234ze as a hazardous substance, but as a PED group 2 fluid. 

R227ea was originally introduced to replace the CFC R114 and as a zero ODP alternative for the fire suppressant Halon 1301. It is also used in metered dose inhalers and in some foam blowing applications.
