How to improve energy efficiency in cold stores

As if some kind of competition, the price of electricity reached record highs in past months. Many industries use refrigerated facilities as part of their daily operations. If we factor in that, in addition to the rise in the megawatt per hour (MWh) price, facility maintenance and upgrades have generally not been a high priority, we found ourselves facing a more-than-significant increase in overall cost that has a considerable impact on company finances.

It’s clear that the refrigeration sector is experiencing a severe crisis, but all is not lost. We should keep in mind that savings can be made in two areas: electricity consumption and facility performance. In this article, we’ll explain how you can start saving.

Carrying out an exhaustive analysis of everyday situations and factors that have a large impact on electricity consumption and coming up with solutions is a good start that will lead to significant energy-related and economic benefits.

Want to cut your electricity bill by up to 15%?

Firstly, you’ll need to take note of your current situation. Information that you should keep in mind includes the amount of time doors are open, door measurements, the difference in temperature between inside the cold store and outside it, the workflow process, workplace habits, door thickness, etc. All of these factors allow us to build an initial picture of the energy efficiency conditions in our facilities.

Once you’ve completed your initial assessment, Kavidoors has a series of solutions for specific cases.
You can find some of them below:

Technical factors

To optimise cold store performance, the project should be assessed, carried out and installed by a qualified and experienced company. The design, such as data collection, the correct choice of technical solutions and the hiring of a trusted fitter will directly affect the equipment’s energy efficiency and, consequently, its electricity consumption.

Industrial door maintenance

This is another important aspect that often goes overlooked. Investing in proper equipment maintenance is an expense that can be recovered in a considerably short period of time. It prevents extra costs and unexpected circumstances such as the complete shutdown of operations, allows a better overview of electricity consumption and increases operational efficiency.

Operating habits

Changing certain workflow habits is possible. Our doors and curtains allow for greater control and monitoring of operations within cold stores, providing information such as the time a door is open and the door’s current status. Door closure, and even remote door closure/opening, is time programmable.

Insulation factors

There are many options for insulation on the market. For one, there is a variety of materials and finishes on certain products: The choice of panel thickness or the type of canvas for high-speed doors depends on your facility’s needs and are factors that should be taken into account. On the other hand, there are specific products such as:
Kavidoors double canvas high-speed door.
These doors offer ease of use, manoeuvrability and smooth operation, improving thermal insulation.

Kavidoors vertical lift cold storage doors are designed to be used in cold stores with temperatures between +0 °C and -40 °C

By incorporating air curtains and installing high-speed doors, automating the closure of canvas doors, they shut off certain areas and ensure a constant temperature.

Experts

There’s no doubt that, to achieve optimum energy efficiency levels in cold stores, installation and maintenance companies are clear allies in the transformation that the refrigeration sector is undergoing. Choosing a suitable partner ensures optimum equipment performance and avoids high energy costs and additional expenses in the long term. Poor maintenance can raise energy bills by more than 15%.

Kavidoors is the “light at the end of the tunnel”. As a manufacturer of doors and curtains for cold stores, many businesses have come to us in search of solutions that will help then achieve, improve and maintain energy efficiency in industrial cold units and, by extension, reduce energy-related costs. In this article, we have explained just a few of the solutions that contribute to greater energy efficiency. If you’re looking for a custom solution, don’t hesitate to get in touch.
