    Arkema Expands Online Information Related to R22 Retrofits

    Arkema’s North American refrigerants website —forane-us.com — has been upgraded and expanded to include a new, on-line seminar focused on the complexities of R-22 retrofitting. All R-22 retrofit information may be reached either from the Forane refrigerant homepage, or may be accessed directly at r22retrofits.com. Both sites include a link to Arkema’s “R-22 Alternatives Training Presentation”, which is a detailed, navigable refrigerants training seminar geared toward technicians in the field. The on-line seminar is modeled after a highly popular Arkema in-person training program about R-22 retrofits, and covers the following key topics:phase-out/transition / R22 retrofits / general issues / component comparisons / functional consideration / operating traits comparison retrofit recommendations. An “Overview” section covers the phase-out of R22 and the EPA timeline, including yearly “milestones” during the phase-out. A “Retrofit Options” section illustrates potential retrofit solutions based on operating pressures and application ranges. A “Retrofit Solutions” provides Arkema’s recommendations for specific retrofit products based on operational data relative to R-22, including capacity, flow rates, TXV change-out, lubricant, system pressures and temperatures, plus retrofit procedures to be followed in the field. A “Retrofit Resources” section provides a wide ranging FAQ section along with contact information for Arkema customer service and technical support.

    GEA Releases Condensers for Transcritical CO2

    GEA has developed a new series of GEA Searle condensers for employment in transcritical carbon dioxide (CO2) systems. The condensers are designed for gas pressures up to 120 bar, and offer various structural characteristics, to enable effective operation under high temperatures and pressures. Heat exchanger bundles have expansion gaps, and the tubes have been extended to increase system durability. Since the extremely high gas-inlet temperatures encountered here give rise to the risk of great thermal stresses, the heat exchanger fins have been segmented to reduce the mechanical burden on the heat exchanger and increase the thermal performance. Leak and strength tests take place before delivery.The range of gas coolers is extensive, enabling the tailoring of units to meet the exacting specification of customers needs. Units are available with multiple bundle configurations, with fan diameters ranging from 630 to 990 mm, with high efficiency EC models available.
