Welcome to the Refrigeration Showcase, which includes comprehensive coverage of the different types of equipment and controls commonly encountered in the field. From ice machines to reach-ins to controls to components, the Showcase is designed to educate contractors about the new commercial and industrial refrigeration products available, so they can help their customers make the right choice for their application.

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 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.

Emerson Lumity E3 Control

Product: Lumity E3 supervisory control for CO2 applications (model numbers RX, BX, CX, and SR) is a new control product that was designed in response to the growing commercial interest in transcritical CO2 systems in North America. The control is part of the next generation of connected refrigeration and facility management controls and is designed to provide comprehensive control of critical systems for food retail and foodservice facilities, while delivering an intuitive, user-friendly and web-accessible experience.

Features: The E3 control for CO2 applications offers a control solution for a lower-GWP refrigeration system; proper and efficient visualization of system operation via one application; and the ability to customize to all standard system values in one view. The control also reduces complexity by converting multiple applications into one, and a single application manages a transcritical rack system with alarming, safety operation, and system control. Faster startup is achieved through simplified one-time setup and constant tuning of parameters.

End users of transcritical CO2 systems who employ the E2 controller will be able to replace it with the E3 CO2 model; users of the standard E3 controller will be able to upgrade it to CO2 version.

This CO2-specific version of the E3 control has so far been programmed to handle such functions as start-up and shut-down, hot-gas injection, liquid injection, desuperheating, adiabatic gas cooling, and parallel compression modulation integrated with high-pressure valve control.

Benefits: The control reduces energy consumption costs by providing the ability to interface with utilities by employing many more communication protocols to optimize energy within a building. Built-in algorithms make it easy to employ demand response, curtailment, and load shedding programs within a store or building. Within the utility application, gas and water consumption were added to expand the utility monitoring capabilities. Schedule setbacks, occupancy schedules, optimizing soft starts, and zone control all are consistent with optimal energy utilization strategies.

Store designs constantly change to meet the needs of consumer preferences. Building management systems (BMS) must be both forward and backward compatible to add new devices to the network, while interacting with legacy devices. They also must be able to grow with the building as it expands for click-and-collect and other store changes. This controller provides that expandability.

Service, maintenance, and installation: The hardware was designed with replacement in mind: a technician isn’t required to reconfigure the hardware to fit the new controller into the same cutout and make the physical replacement. A set point conversion tool supports the transition from the E2 to the E3 controller. The user interface includes Smart Alarms and Performance Meter modules, which are intended to make it easy for technicians to diagnose and troubleshoot problems quickly. Navigation is intuitive. Its web-based accessibility eliminates the need for separate software to set up the controller; it’s available in any internet browser.

Warranty information: Two-year warranty with no extended warranties.

Sporlan Ball Valve
Sporlan Division of Parker Hannifin

Product: The EBV(T)-PR ball valve with integral pressure relief is designed for use with refrigeration and air conditioning systems. The valve allows for positive shut-off in one direction and then relieves pressure in the other direction. It protects systems from pressure spikes when servicing the equipment.

Features: The ball valve has a design working pressure of 1,305 psig (90 barg), which is ideal for use with CO2 refrigerants. It can also be used with other Class A1 refrigerants (HFC, HCFC, and HFO) and has a range of connection sizes — from 3/8 to 11/8 inches. It is available with and without an access fitting. This single valve would replace a current ball valve plus a check valve plumbed around the ball valve. It allows the evaporator coil to be isolated without over-pressurizing due to warm-up.

Benefits: The EBV(T)-PR ball valve with integral pressure relief allows for greater system design flexibility, increased productivity, and significant material cost savings. This compact solution eliminates the check valve and associated brazing involved when piping a ball valve and check valve in parallel to protect a system from overpressurization. The pressure relief function ensures that the isolated section of the refrigeration system is safe from building extremely high pressures that would cause damage.

Service, maintenance, and installation: The reduced installation time is a cost savings. A check valve would have to be installed in parallel to a standard ball valve in the system to achieve the same function today. It would require a significant increase in braze joints, which complicate the installation and potentially leak.

Warranty information: Standard one-year warranty.
