Danfoss has released its new EVR v2 solenoid valves, having completed a wide series of improvements to the range of EVR valves throughout 2017. Reinforcements and rationalization now make the valves capable of accommodating higher refrigerant pressure and a broader range of applications while reducing the references, inventory, and servicing time. Decisive benefits for HVACR professionals include reduced applied and operating costs without compromising on reliability in all applications — from cold rooms to chillers and heat pumps.
Higher MOPD and new features compatible with modern refrigerants
The Danfoss EVR range of solenoid valves has a proven track record with more than 30 years of presence in a wide scope of air-conditioning and refrigeration applications such as walk-in cold rooms, display freezers and refrigerators, chillers, rooftop units, or close controls. Ten key features have been applied to enhance design robustness in more applications, increase functionality, and make service easier.
The valves will be progressively available at wholesalers through March 2018.
Danfoss EVR v2 valves are now optimized for manufacturers and installers in:
EVR valves from Danfoss are ideal for applications such as food retail display cases since they enable service and maintenance to be carried out quickly, with no disruption to a store’s business hours. There is no need to de-solder the complete valve and put a new one into the system. Instead, the valve body can be left in place and the internal parts replaced as required in order to get the system up and running again quickly. Service kits are also available.
Fewer models, broader scope
“Our revitalized EVR range saves on applied, development, and storage costs. From April 2018, the new EVR range will have completely replaced the production of the actual EVR, EVRE, and EVRH ranges. Thirty percent fewer — but more versatile — models suit more applications and refrigerants while being backward compatible,” says Allan Chara, marketing director for cooling refrigeration controls, Danfoss. “We come now with revitalized high-quality ranges of products and services for air-conditioning and refrigeration businesses that are compatible with today’s demands for higher reliability, versatility, and efficiency —enabling our customers meet the demands of the industry. All of this, as well as other Danfoss products like Optyma condensing units, T2/TE2 thermostatic expansion valves, electronic controllers, pressure switches, and more, is available from major wholesalers and can be selected online with the new Danfoss Coolselector.”
The wide range is available for cooling capacities from 3 to 410 kW (0.85 to 116 tons) in liquid line, 0.3 to 65 kW (0.08 to 18.3 tons) in suction line, and 1 to 350 kW (0.28 to 99 tons) for hot gas bypass, with connection sizes from 6 mm to 42 mm - 1/4” to 2 1/8”. They have the same built-in length as the actual EVR with the corresponding connection size except for the bi-metal connections.
The complexity reduction leads also to cost optimization in air-conditioning systems. For installers, the streamlined range means the right valve is more likely to be available, thus helping manage inventory and avoid logistics issues.
The changeover does not impact the coil program (SCN-SCT) and the EVU/L/CSV non-serviceable valves.
