Cost of installation 1,500.00 200.00 1,300.00
Cost of Energy per month (Will be different based on your country) 500.00 150.00 350.00 per month
Average Maintenance cost per six months 500.00 0.00 500.00 per six months
Total cost for 2 years $ 24,600.00 $ 10,400.00  
Total saving for 2 years     $14,200.00

The above costs are indicative and will vary depending on your country, taxes, duties, man power cost etc. However, this gives you a general idea of the cost savings. The modular walk-in cold rooms & AC units considered above are made in Europe. We also provide these units from our Asian units, which will be still cheaper.

Is it suitable for you?
cheap-coldroom-with-window-ac-vackerglobal-africa

In order to decide whether our system is suitable for you, you may consider these facts:

  1. It may take up to 60 minutes for the first time cooling up to 4°C. Since these are Window AC/Split AC units, it takes a longer time to cool down. However, if we use additional Window AC/Split AC units, we can improve the cooling time.
  2. We recommend our cheap cold stores for applications with maximum 6 door openings per hour. If you have more door openings, you can increase the number of AC units. If you are a large hotel needing frequent door opening, we recommend having a big Vacker cold room and a small conventional cold room. In such case, you can take the items one in an hour from Vacker walk-in cold stores and keep it in the small cold room. This way, you will be able to save a lot of money on capital, operational and maintenance costs.
  3. If you are opening the door regularly, the ideal temperature is 2.2°C (36°F) or above. If you need temperature below 2.2°C, we can provide additional AC units and recommend very few door openings. Eg. If you are a cold storage, which you open only a few times a day, then it is fine to achieve and maintain above 0°C.
  4. These are not freezers. Our systems cannot operate as freezers. These can operate only above 0°C (32°F). If you want below 0°C, you have to depend on conventional freezers only.
  5. If you are in a country having extreme cold conditions, please consult us. It will work in such conditions, but we need to select particular brands and capacity for best performance.
What are the applications of these cheap cold rooms with split AC/Window AC units?

You can use these economic walk-in cold rooms for any normal non-freezing applications, similar to conventional cold rooms. The major applications of our customers are as below:

  1. By farmers for storing their fruits and vegetables near to their farm before further processing. They will have limited power supply and probably limited space. They can easily install a small cheap cold store without much investment.
  2. Storage of meat especially in restaurants and distribution centres. For such usages, the temperature will be normally 3-4°C. Restaurants and hotels are always short of space. Installing a walk-in cold room with the big cooling plant is always a constraint. Our economic cold rooms are ideal for such situations.
  3. economic-flower-cold-room-coldroom-vackerafrica
  4. Cold stores for flower storage. The conventional walk-in cold rooms are not good for flower storage because of the high flow rate of air. Powerful airflow reduces life span of fresh flowers. Our units do not generate high airflow. Hence, these units are excellent for flower storage. Our customers use for the fresh cut flower from farms, flower shops, wedding flowers etc.
  5. Wine cellar for storage of wine at a controlled Wine cellars in restaurants and hotels will have space constraints. As our cheap units do not need big cooler units, you will have all the convenience.
  6. We also have many customers using our cold rooms as bar coolers. The applications are similar to wine cellars.
  7. Brewery cold rooms do not require regular door opening. Hence, our cold rooms are best suited for such applications too. As our cold rooms deliver a steady temperature, these are suitable for brewery applications.
  8. Walk-in cold stores for fragmenting and laagering process. Such processes require a temperature of around 10°C (50 °F). Hence, we have many satisfied customers in this segment too.
  9. Cold rooms for dairy products such as milk, cheese, butter etc. We have hundreds of customers using our modular cold rooms and mobile cold rooms for storage of dairy products. Cheese dries fast if airflow is high. As our units are having very low airflow rate, this is not a problem at all.
  10. Our customers also use our modular cold rooms for Mortuaries, funeral homes, crematoriums etc. operating between 2°C to 4°C.
  11. For restaurants and hotels for all types of food, including cooked food. Our modular cold stores are economical for all types of restaurants applications.

Economic mobile cold rooms

We can supply economic models of mobile cold rooms using window AC units as seen in this image. You can tow the mobile cold store to any place you want and simply plug into the local power supply. You can also provide these cold room units on lease basis to customers as per their requirements. This becomes a continuous stream revenue for you.

If you want to transport any goods for short distances in a cold condition, you can very well do so after disconnecting the power. You can store the goods, cool it down sufficiently and disconnect the power. Thereafter you can move the mobile cold room to another place. But, do not open the doors until you are ready to unload the items at the destination. The distance you can cover depends on your local climate conditions. If you inform us your location, we will be able to help in estimating the distance you can travel without power.

Use our walk-in fridge with Split AC instead of large-sized front door refrigerators

cheap-Vegetable-cold-room-with-split-ac

A small cold store will be cheaper than your double door industrial refrigerator. Thus, the cold room will be of bigger size. So think of the economics of a big refrigerator and instead you can go for a complete cold room. You can use it for all refrigeration applications such as fruits, vegetables, flower etc. However, you may note that this may not be suitable for a supermarket where a lot of customers open the doors very frequently. If the door opening is under your control then it is fine and you can ensure a limited number of door openings.

How the modular cold room with window AC works?

The operating principle of our units is same as that of conventional big cooling units. The big cooling units work more on airflow using big powerful fans. These fans circulate the air at a much faster rate. Any normal AC units are capable of cooling down the atmosphere sufficiently to very low temperature. However, the electronic circuitry of all such units is having limitations to reduce the temperature below 16°C. Our special circuitry permits the AC unit to work in a different mode permitting it cool down further.

Most of the conventional cooling units are oversized

When you install a conventional cold room, the conventional cooling units are generally oversized. This is because of different design criteria. This escalates your initial investment as well as regular electricity bills. In our cheap modular cold stores, you can always add an additional AC unit if you feel that you require more cooling power. (However, this will depend on the size of the cold room, present position of the AC etc.)

Energy saving cold storage rooms

Energy-saving-modular-cold-room

Presently energy saving is a huge subject in view of concerns about the environment. As our cold rooms are operating with window/Split AC units, they consume very small electric power. The conventional chiller units consume a huge amount of power for their compressors and evaporators. All of them generally require 3 phase electric power. We will require only single-phase electric power unless the size is huge. Our cold stores save up to 40-50% of power compared to conventional units. Hence our cold storage rooms are very environment-friendly. Obviously, as you can imagine, the home ACs consume very small energy compared to huge monstrous chiller units.

You regular cold room supplier will not promote our units since their revenue comes from their chiller units. The supply & installation charges are huge. And thereafter you have to depend on them for regular maintenance as well.

Installation of economic cold stores with AC units

We supply the modular cold storage rooms, which you can easily install using local technicians. We provide installation videos for the installation. You do not require any specialized technical skills. The modular cold room comes with floor and walls. We supply the modified AC along with the cold room. The complete installation will not take more than 60-90 minutes for a small cold storage room. You will be saving thousands of dollars towards installation costs itself. Our helpline is available for any assistance.

What is the warranty on the units?

cold-room-on-generators-vackerglobal

We offer two years warranty on the modified AC units along with the electronic circuitry. These units have been working for past 10 years.

Are these cold storage rooms reliable?

We have carried test of the complete system of modified AC units along with our electronic circuitry at NYSERDA, (the New York State Energy Research and Development Authority). They have certified that the system works perfectly without overburdening the AC units.

There is no worry of overburdening the AC units since our circuitry takes care of controlling the AC units. In fact, if the no. of door openings are 6 per hour, the AC unit will have a longer life, since the number of cycles is reduced.

Cold rooms with temperature mapping study

We as cold chain experts, carry out temperature mapping study and qualification of cold storage rooms. We can provide supply, installation and temperature mapping study of these modular cold rooms with split or window AC units. This is useful if you are using these cold rooms for keeping medicines between 2 to 8 °C. Many medicine manufacturers and local authorities stipulate temperature-mapping study for storage for medicines.

As per our experience, the risk at the lower side is very minimal with our system. Hence, we have to focus only the upper limit, which we can achieve very safely. Hence, if you are going to use these cold rooms for storage of medicines, we can complete proving the performance by conducting a temperature mapping study at the site for additional charges. Thus, you and your auditors will have proof that the cold storage room works exactly between 2 to 8°C.
