Supermarket and Grocery Refrigeration
High efficiency EC Motors save electricity
A "typical" supermarket has as many as 400 evaporator fan motors in refrigerators and freezers which run 100% of the time, even when the store is closed. The efficiency of the "shaded pole" AC motors usually used for this application is 15-25%. This means for every Watt used to generate airflow, another 4-5 Watts are wasted as heat. Subsequently even more power must be wasted to remove that heat from the cold space.
Changing remote or integral (plug-in) display cases to use ECR motors, with efficiency up to 70%, reduces power by over two thirds. This leads to a cost saving of $45 or more, per motor per year (based on a power cost of $0.11/kWh). Payback can be measured in months and ECR motors are tested to a design life of over 10 years, so replacement costs can be reduced too.
Quiet airflow solutions improve customer satisfaction
Low noise is critical for supermarket refrigeration systems. Multiple fans used by large rows of cabinets can cause noise levels to be intrusive, driving customers away. To combat this problem low noise fans and motors are needed, and Wellington offers some of the quietest air movement solutions available.
Our patented biomimetic fan designs cut air noise, while our ECR2 fan motor uses a three phase sine wave drive usually only seen in high-performance industrial motors, to give incredibly low levels of motor-induced noise and vibration; as much as 4.5dBA less than other EC motors.
The variable speed capability, and easy field programmability, of our motors means that fan speed can be tuned to give the least possible noise in a particular installation. When combined with our SCS refrigeration controls, motor speed can even be varied in real time.
Variable airflow control improves performance and flexibility
Airflow in supermarket display cabinets must be closely controlled to protect the valuable perishable goods - particularly in open-deck cabinets, where airflow variations can disturb the air curtain, leading to wasted power and spoilage.
However, the best amount of airflow is not always the same. Different cabinets encounter different environmental conditions, and even within a single cabinet, airflow needs will change with load, door state, night curtains, temperature, icing, and many other variables. Until now, almost all supermarket cabinets have ignored this opportunity.
Now Wellington offers the chance to improve performance with Smart Airflow Management. Our ECR motors can be programmed in place, allowing individual cabinets to be tuned once installed, and our SCS refrigeration controller can control fan speeds in real time. Wellington's speed control system works over mains voltage, meaning no additional low voltage connectors or wiring harnesses are needed. We also work with OEMs to enable their own (or third party) control systems to use ECR speed control.
Fan assemblies cut manufacturing costs
For OEMs who want to avoid the labour cost, space requirement, and logistical complexity of assembling motors, fans, and baskets,Wellington's ECF fanpacks are the perfect solution.
Their integrated design means they are more efficient and quieter than off-the-shelf fans and baskets. They are made from high-specification impact-toughened polymers, so the risk of bending metal blades is eliminated, and they can be used in all temperatures from freezer evaporators to condensers. With easy speed programmability, the need for multiple fan pitches is also eliminated.
Built-in iBeacons help you connect with customers
Digital marketing is the next big thing in retail. To make location based campaigns easy, Wellington's SCS refrigeration controls have a built-in iBeacon. Unlike conventional iBeacon "buttons", it can never get lost or stolen, and there is no battery to go flat. Our smartphone-based Service interface allows easy configuration.

Telemetry enhances maintenance
Data based decision making is increasingly important in today's world. For supermarkets without a centralised control system, or for cases not connected to that system, SCS Connect System's telemetry and data analysis capability can help schedule and predict maintenance needs, and give you the peace of mind of HACCP temperature logging.
Our low cost, robust solutions suit developing markets
Retail in the developing world has its own special needs. Rugged, low cost solutions that handle the most important functions, without the complexity and cost of systems designed for developed markets.
Wellington has a strong presence in developing markets such as Latin America, and understands their needs well. We offer simple solutions which give developing world retail operators a first step into energy efficiency and store management systems.
