Figuring out which refrigeration equipment or controls package will work best for an application can be challenging. Larger supermarkets, cold storage facilities, and restaurant chains often have in-house personnel who make this decision, but they still value the input from their local contractors who service their equipment. Smaller regional stores and restaurants typically do not have these in-house resources, so contractors usually have a larger role in recommending equipment solutions.

For both of these situations, the Refrigeration Showcase will help contractors learn which refrigeration unit, component, and/or control will best serve the needs of their customers. Manufacturers have provided detailed information for the Showcase that includes the benefits end users will experience by using their products, as well as how they have made their equipment easier for contractors to install and service.

For food retailers and restaurant owners, their priority is making sure that any new equipment keeps their products safe, fresh, and cold — reliably and efficiently. The products highlighted in the Refrigeration Showcase are designed to do just that.

Keeping tight control of the temperature is extremely important in refrigeration systems. That's because a temperature swing of just a few degrees in one direction or another can ruin fresh and frozen food items, resulting in high losses for the food retailer or restaurant owner. The right controls can also reduce energy costs, and many of the solutions discussed here offer both temperature control and energy savings.

Product: The ArtikControl™ line of controls technologies is designed for use in retrofit applications for walk-in boxes, reach-in displays, and stand-alone commercial refrigeration units. ArtikControl controllers use AI machine learning to take full control of the commercial refrigeration units, and systems can now be controlled using a smart device, such as a phone, tablet, or laptop.

Details: Historically, standard motors running evaporator fans have operated exclusively at full speed, 24/7/365, and continue to do so. ArtikControl controllers fortify walk-in coolers and freezers with robust refrigeration technology that eliminates the need for constant energy consumption. Retrofitted equipment saves energy and money while also reducing wear and tear on the compressor. Similarly, the defrost cycles of traditional systems turn on and run for a set block of time, regardless of whether a defrost is truly needed. ArtikControl relies on two temperature sensors — with one directly inside the refrigeration coil — to accurately determine when and how long to run the defrost cycle.

Features: ArtikControl controllers are a unique cooling solution that are capable of saving companies as much as 80% or more in energy and cost savings.

Benefits: Refrigeration technicians can now monitor users’ commercial refrigeration systems from a smartphone, tablet, or laptop. The system will send an email or text if there is a problem with the system and remote defrost is accessible. The company also offers a concierge package, which allows the monitoring of refrigeration systems 24/7/365.

In most cases, ArtikControl™ customers enjoy a return on investment of less than two years. Customers with walk-in freezers typically see a return in as little as 13 to 14 months.

Service, maintenance, and installation: Once ArtikControl technologies are installed, the controller will take 60 days to learn the refrigeration systems but will adapt to the changing conditions. The system takes readings every 60 seconds, and the system will send out alarms via text and email should the system have a failure or operate outside the normal temperature set points. The controls offer predictive analysis of the operations of the refrigeration system and will notify if the refrigerant is low or if there are condenser issues, as well as behavioral issues such as leaving the door open too long or power failure. Should ice form on the box, refrigeration technicians can perform a remote defrost from anywhere on their phone or tablet.

Warranty information: Five-year warranty on all equipment installed, and should the client go with the concierge yearly monitoring for 10 years, the warranty will be extended to 10 years.

Product: The small and compact design of Sporlan's Type NX thermostatic expansion valves (TXVs) makes this product ideal for foodservice and food retail applications such as display cases, ice machines, frozen drink dispensers, and commercial kitchen refrigerators and freezers.

Details: Sporlan constructed the NX valve with a single, balance-ported pushrod designed to help flush out any solid debris build-up. The bleed port feature allows the system refrigerant to bypass the pin and port. System designers can utilize this feature to alter system performance for a variety of reasons. Bleed port options are available upon special request. In the past, Sporlan assigned a letter code to each refrigerant, but Type NX valve models have been consolidated by refrigerant groups to simplify product application. The NX valve works with all common HCFC, HFC, HFO refrigerants and their blends, along with R-290.

Features: Features include long-lasting and durable stainless steel diaphragm and weld design; single-pushrod balanced port construction; unique design to minimize solid debris build-up; internal or external equalizer; easily adjustable superheat setting; and high-strength silver soldered joints with solid copper connections.

Benefits: Type NX valves are built with a stainless steel capillary tube laser welded to the sensing bulb and element housing to withstand the bending during installation and improve endurance to vibrations while in service. The forged brass NX valve body is available with a straight-through flow configuration and ODF (sweat) copper connections. The valve can be supplied with either an internal or external equalizer and features a field adjustable superheat stem. Valves with fittings in metric sizes are available upon special request.

Service, maintenance, and installation: Standard static superheat settings vary based on the system refrigerant selected, but the valves are set to approximately 4°F static superheat based on the newer refrigerants such as R-448A. Special settings are available upon request. The seal cap utilizes a mechanical knife-edge seal. Sporlan offers two optional inlet strainers for use with NX valves: an insert strainer and an integral strainer. The insert type strainer is placed into the inlet fitting prior to brazing and can only be serviced by disconnecting the liquid line. The integral strainer, a feature of the SNX(E), is serviceable and allows the strainer to be removed without disconnecting the valve from the liquid line.
