Parker’s New FR Series Thermostatic Expansion Valves Precisely Control Superheat in Smaller Capacity Refrigeration Cases or Reach-Ins

Modulating valves maintain precise superheat under varying loads and conditions for increased operational efficiency.

WASHINGTON, Mo. – January 22, 2018 – The Sporlan Division of Parker Hannifin Corporation, the global leader in motion and control technologies, today announced the launch of its FR Series thermostatic expansion valves (TEV) for smaller capacity refrigeration cases, reach-ins, and other food service applications. The modulating thermostatic expansion valves precisely control superheat under varying loads and conditions. Maintaining precise superheat control improves operational efficiency and can lead to reduced refrigerant charge and equipment cost due to evaporator optimization.

With nominal tonnage capacities of 1/10 and 1/16 tons, these new valves enable micro-system optimization, offsetting the effects of LED lights, improved insulation and doors, and smaller anti-sweat heaters — increasingly used in today’s refrigeration cases — which can lead to reduced load. The new valves’ selective thermostatic charges provide application-specific superheat optimization for enhanced system efficiency that cannot be matched. Plus, FR Series thermostatic expansion valves work with all common refrigerants such as R-404A and many new refrigerants such as R-290, R-448A or R-449A.

Ongoing regulatory changes impact both manufacturers and end users of large and small refrigerant cases and reach-ins. With the ability to maintain target superheat under varying loads and conditions – unlike capillary tubing — FR Series valves offer increased energy efficiency to meet pending regulations, while minimizing cost and refrigerant charge. This eases the transition to low global warming potential (GWP) or natural refrigerants and helps meet refrigerant charge restrictions when using flammable refrigerants such as propane (R-290).

“Sporlan takes the global initiatives to improve refrigeration equipment energy efficiency and to reduce the effect of refrigerants on the environment very seriously,” said Glen Steinkoenig, TEV/PRV/distributors product manager. “With the industry’s only 1/16- and 1/10-ton capacities, it is now possible to optimize micro-sized food service equipment performance over a wider range of operating conditions reducing energy use by 8 to 20 percent while enhancing food safety. As an added bonus, using FR series valves has enabled system design and development time savings while reducing time to market for new product introductions.”

The FR Series of thermostatic expansion valves will be on display at the 2018 AHR Expo in McCormick Place, Chicago, January 22-24 (Booth #4936).
