Sustainable Refrigerant to Become Standard on Refrigeration Systems

By |

ATHENS, GA – With significantly reduced global warming potential (GWP), new-generation refrigerant R-452A will become the standard for new Carrier Transicold transport refrigeration units in North America beginning later this year, helping customers improve sustainability profiles and achieve regulatory compliance. 
“Carrier Transicold truck and trailer refrigeration units have been qualified for R‑452A since 2017, and it has been available as a customer-specified option for several years,” said Bill Maddox, Senior Manager, Product Management, Carrier Transicold. “R‑452A is already standard with some of our newer units, and we’re pleased to expand this standardization to the broader array of Carrier Transicold products, effectively halving the refrigerant GWP of our transport refrigeration offerings.”

Beginning in October, R-452A with a GWP of 2,140, will become the standard refrigerant for all Carrier Transicold models that currently use R-404A, which has a GWP of 3,922.

The timing of the transition will help California customers placing orders for 2023. The California Air Resources Board (CARB) this year approved a measure requiring all new transport refrigeration units placed into service in 2023 to use a refrigerant with a GWP of less than 2,200.

In 2025, Canada will require refrigerants with a GWP of less than 2,200 in new transport refrigeration units, to reduce greenhouse gas emissions in accordance with the Kigali Agreement of the Montreal Protocol.

Previously, there was a significant cost differential between the new and traditional refrigerants, however over the last several years that has diminished with changing demand and refrigerant production trends, helping to encourage adoption of the more sustainable R-452A.

Maddox added some customers may consider switching refrigerants for units already in service, noting that with relative ease, Carrier Transicold customers can transition newer existing equipment from R-404A to R-452A. Unlike some competitive systems that require replacement of a thermal expansion valve when converting, late-model Carrier Transicold systems – those with an electronic expansion valve – simply require a software upgrade along with purging the R-404A and replacing it with R-452A. On Carrier Transicold truck units and older trailer units that use a mechanical expansion valve, the valve will require a manual adjustment or, in some cases, replacement based on the age of the model.

Standardizing on lower GWP refrigerants is part of Carrier’s commitment to reducing its customers’ carbon footprint by more than one gigaton, while also achieving carbon neutral operations by 2030, as outlined in its bold Environmental, Social and Governance (ESG) Goals.

Canadian Driver Dale Gray: US Truck Regulations are Tougher

By |

Dale GrayIntrusive and excessive government regulations have been reported numerous times in and further proof of probably the greatest threat to the trucking industry, and particularly owner operators, comes from Dale Gray of Trenton, ON.

Dale is a veteran and drove a truck in the military before becoming a driver in civlian life in 1997.  For over two years now he has been driving for Scotlynn Commodities Inc., of Vittoria, ON a Canadian transportation operation that has a sister company with several farms in Ontario and the USA that grows numerous items ranging from sweet corn to pumpkins.

Trucking both in the states and in Canada, Dale says American “rules are not as lienient.”

Although the hours of service regulations in both countries are similar, he prefers those in Canada because it allows him to be more profitable.  For example, he can legally truck 13 hours in his country, compared to only 11 hours in the states.

“I prefer the the 13 hours driving time, because I can drive more hours.  It makes a difference if you are paid by the mile,” Dale says.

He also notes he can split his sleeper berth hours by doing 8 1/2-hour increments during the day.  In the US, the hours must be in 10-hour blocks.

“I can’t sleep for 10 hours,” he states. “Canadian rules are more user friendly.”

Speed limits are another matter, according to the 57-year-old driver.  He notes Canadian speed limits in most of the country are 100 to 110 kilometers (65 – 70 mph).  He prefers the higher American speed limits which range from 55 mph in California to 80 mph in Utah (75 mph in North Dakota where this interview took place).

Dale drives a 2012 maroon 386 model Peterbilt powered by a 485 hp Paacar MX diesel.  The truck has a 60-inch sleeper with a 244-inch wheelbase and 13 speed tranny with overdrive.  He pulls a 53-foot Utility trailer with a 2100 Advance Carrier refrigeration unit.  Dale notes the reefer has a 120-gallon fuel tank that will run for a week. 

“The reefer unit has a larger fuel tank so it can be shipped by rail,” he says.

Dale’s favorite thing about trucking is even though he is a company driver it is similar to being your own boss.  “There is no one looking over your shoulder all of the time.  In part of my military career, I was stuck in an office.  I didn’t like that,” he states.

The worst part of driving is the attitudes of both four wheelers and truckers seems to have worsened over the years.

Dale hauls a lot of fresh produce grown by Scotlynn, plus he delivers a lot of frozen doughnuts and dry freight.  On this particular day he was waiting to pick up a load of macaroni in Grand Forks, ND for delivery in Ontario.
