The warranties for the hybrid Vector 8500 and Vector 8600MT units now include 48-month/8,000-hour major component coverage for the engine, generator and compressor.

This compares with 36-month/6,000-hour coverage on earlier models. Additionally, the APX™ control’s microprocessor and stepper valve modules are warrantied for 60 months/10,000 hours – one year longer than comparative control systems.  The move reflects the series’ reputation for reliability, says Carrier.

“Vector systems deliver dual benefits of reduced maintenance and higher system reliability because they are less complex than conventional mechanical systems and comparative semi-electric systems,” said Patrick McDonald, product manager – trailer, Carrier Transicold.

“Our latest-generation Vector units build on this legacy, employing a fully hermetic electric scroll compressor with 70 percent fewer moving parts than a traditional reciprocating compressor.

“Eliminating mechanical parts, such as belts, pulleys, compressor shaft seals and vibrasorbers that require service and periodic replacement, reduces service requirements while improving reliability. In short, if it’s not there, it can’t break,” McDonald added. “It’s one of the key reasons we’re able to offer improved warranty coverage for our latest models.”

The Vector units continue to offer 12 months of unlimited coverage and 36-month/6,000-hour limited coverage for the entire unit. On the multi-temp Vector 8600MT, basic warranty coverage for the new, smarter remote evaporators has been extended to 36 months/6,000 hours, triple the warranty for prior remote evaporators.

The Vector 8100 engineless unit for stationary cold storage applications also now features improved warranty coverage, with the run-hours limit for 36-month basic coverage and 48-month major component coverage now extended to 10,000 hours.

The Vector platform’s signature E-Drive all-electric refrigeration technology means refrigeration and heating operations are 100 percent electric. All models can be plugged into an AC electrical supply when parked, providing full refrigeration capacity without engine noise, emissions or fuel consumption.

Over the road, the 8500 and 8600MT units are powered by an on-board generator driven by the unit’s diesel engine, whereas the Vector 8100 unit does not require the engine-generator combination, because it is designed for stationary cold storage.

UKWA moves office

London: The United Kingdom Warehousing Association has moved offices to 11 Gower Street London WC1E 6HB.

Telephone and fax numbers have changed too: T 020 7636 8856 and F 020 7636 7865.

E-mail addresses for UKWA staff remain the same.

Roger Williams, the association’s chief executive said: “The landlord at our previous office applied successfully for change of use, leaving us with little choice but to vacate.  Our new home is only a mile or so away so we hope our members will make use of the new facilities that we can offer.

The Association had been at its previous address in the Strand, central London, since 1977.

Dutch retailer converts R-507A refrigeration systems in 200 supermarkets

Neu-Isenburg, Germany: A Dutch retailer is converting the refrigeration systems in some 200 of its supermarkets to DuPont’s new Opteon XP40 (R-449A) refrigerant.

The switch is part of the retailers programme to cut its carbon dioxide (CO2) emissions and follows trials carried out with DuPont Chemicals & Fluoroproducts and the Dutch consultants PW Vlaskamp BV Refrigerants Consultancy, Sleeuwijk.

Opteon XP40 is part of the low GWP refrigerant family from DuPont and is suitable as an alternative to R-404A/R-507A in new and existing commercial and industrial medium and low temperature refrigeration systems.

The refrigerant’s global warming potential is 65% lower than existing refrigerants and its elevated energy efficiency means it can help in bringing about a significant reduction in the overall CO2 emissions arising from refrigeration system operation.

The Dutch retailer has the target of cutting its CO2 emissions per square metre of sales floor by 20% relative to 2008 levels by 2020. This also involves reducing the overall greenhouse gas emissions arising from leaks and energy consumption by medium and low temperature refrigeration systems so far operated with R-507A. The company accordingly tested various alternative refrigerants with reduced global warming potential.

In the course of this project, three supermarkets were converted to Opteon XP40, one from R-407F and two from R-507A. The conversion was carried out by Retail Technics. The work took three to four hours in each case and was carried out outside opening hours. Once the original refrigerant charge had been removed, the filter dryer was firstly replaced, as is usual during servicing.

The system was then evacuated, subjected to leak testing and filled with Opteon XP40. Since the company uses electronic expansion  valves and the Danfoss ADAP-Kool system, the system set up was very easy for Opteon XP40 with  new coefficients entered via laptop.

No further components had to be replaced nor was an oil change required. Measurements before and after the retrofit revealed that this refrigerant has a distinctly higher energy efficiency than the previously used R-407F and R-507A.

The technical manager says: “The conversion to Opteon XP40 was completely straightforward and unproblematic in every case. Calculations carried out together with DuPont and Vlaskamp have shown that the capital expenditure will be paid back within an acceptable time due to the refrigeration systems’ significantly lower energy consumption. Management has therefore decided to convert some 200 systems which are currently operated with R-507A to the new DuPont refrigerant. Work started in September 2014 and is set to be completed shortly.”

The consultant has calculated that this conversion to Opteon XP40 will cut total direct greenhouse gas emissions by 10,360 tonnes of CO2 per year. The company is thus anticipating the new European F-Gas Regulation (EU) No. 517/2014 which enters into force on 1 January 2015 and specifies that the number of tonnes of CO2 equivalents available on the market will be gradually reduced over a 15 year period.

In addition, from 1 January 2020, servicing systems using HFCs with a GWP value of 2500 or more will be prohibited for the majority of commercial applications. Changing R-404A/R-507A refrigeration systems over to Opteon® XP40 will ensure that these installed base systems will continue to comply with the requirements of this regulation for the remainder of their service life.

This discipline is for the company an extra step next to the future new installations which will be built according to the CGF resolution.
