Italian manufacturers Dorin, Arneg and SCM Frigo have all become gold partners in the R744.com market for CO2 (R744) cooling and heat pump products, silver upgrade.
Dorin, with over a century of experience manufacturing compressors, began to develop CO2 compressors 30 years ago.
OEM Arneg produces a range of transcritical refrigeration racks, from small Mini Booster to industrial-sized BoosterXL, as well as remote cabinets for CO2 systems.
SCM Frigo offers a wide range of R744 products including subcritical and transcritical racks, cascade systems and chillers.
Dorin expands R744 to new applications
Dorin has a large portfolio of CO2 compressors, from smaller sub-critical models to larger models like the award-winning CD600. The CD600 is a 6-cylinder semi-hermetic compressor with a flow rate of up to 53.2 m3/ hr (1,878.7 ft3/ h) and engine power from 50 to up to 80HP. Suitable for commercial and industrial applications, it is the largest compressor in its class, according to Dorin.
Dorin’s latest development is a series of CO2 compressors for mobile HVAC applications such as e-buses and railways. These BOXER compressors were presented to the world at Busworld 2019 and officially launched earlier this year after a period of testing and improvement.
BOXER compressors have a compact and symmetrical design. Their height of 235 mm (9.24 inches) is up to 42% less than that of traditional V-shaped compressors of similar capacity. “This makes the BOXER range an ideal solution for rooftop installations where compressors need to be as compact as possible,” said Dorin.
The BOXER range offers cooling capacities from 4 to 28 kW (1.1 to 8TR) at an evaporating temperature of 10 ° C (50 ° F) and heating capacities from 4 to 23kW (1.1 to 6 , 5TR) at an evaporating temperature of -20 ° C (-4 ° F). The units are inverter driven, with a range of 25 Hz to 70 Hz.
Arneg units for small stores
With CO2 refrigeration has taken hold in the small store market in recent years, Arneg is ready to expand this market with its Mini Booster rack, designed for small and medium sized stores.
The Mini Booster can be used for indoor or outdoor applications, with optional soundproofing and a frame that can store up to six compressors. Its cooling capacity goes up to 94 kW (26.7TR) for medium temperature applications and up to 20kW (5.7TR) for low temperature applications. It also has heat recovery for domestic hot water and heating systems.
Arneg also offers the even smaller Globo unit, which offers 14 to 38 kW (4 to 10.8 TR) of medium temperature capacity and 4 to 10 kW (1.1 to 2.8 TR) of capacity at low temperature.
Arneg’s latest development is the introduction of two new cabinet series with “top visibility” and “maximum energy efficiency” designed specifically for CO.2 refrigeration systems.
The London 4 series are semi-vertical cabinets. They are suitable for “normal and low temperature” applications, as well as “heated and covered shelves, bread or fish counters,” Arneg said at the launch. London 4 cabinets are customizable with a range of materials and have curved, square or chamfered corners.
The Arles series have eliminated metal supports for furniture, creating a product where the display is 100% glass. The cabinets are available as a service counter or semi-vertical for assisted sales and self-service.
New meeting of the SCM Frigo CO installation2 demand
In August, SCM Frigo, responding to the increased demand for CO2 equipment in Europe, opened a new 13,000 m2 (139,931 feet2) an environmentally friendly facility housing the company’s headquarters and a manufacturing facility in Sant’Angelo di Piove di Sacco, Italy. The new factory gives SCM Frigo the opportunity to expand its production range to meet the demand for a wide range of systems and capacities.
One product that has seen increasing demand over the past five years is CO2 condensing unit. “We manufacture 1,500 to 2,000 units per year, and that number is growing,” said Darren Lacroix, International Business Development at SCM Frigo. “There is a growing demand, both in Europe and in the APAC region. “
Condensing units are best suited for small grocery stores or convenience stores, Lacroix noted. Low temperature capacities range from 3 to 10 kW (0.85 to 2.8 TR), while medium temperature capacities range from 8 to 20 kW (2.3 to 5.7 TR). Usually one of each is used in a store.
