Expert Guide to Choosing and Pricing Water Coolers

Drinking cold water in summer is just as enjoyable as having a warm cup of tea or coffee in winter. By using a water cooler, you can easily access fresh cold water or hygienic hot water for preparing beverages, simply by connecting the unit to electricity, without the need for special facilities.

In general, water coolers are used to supply cold and hot water in public places, commercial centers, offices, hospitals, shopping malls, beauty salons, sports clubs, mosques, and similar environments.

Therefore, with a water cooler available, there is no longer a need for a refrigerator to prepare a cold drink, nor is it necessary to use a stove or samovar to make a cup of hot tea.

These appliances (such as refrigerators and samovars), in addition to requiring a large installation space, are relatively expensive and involve high purchasing costs.

In contrast, water coolers are manufactured in various models with compact and suitable dimensions, making them ideal for offices, companies, banks, schools, mosques, waiting halls, sports or beauty centers, and other public areas. Moreover, they can be purchased at a significantly lower cost compared to the mentioned appliances.

Water Cooler Components and Structure

As you know, a water cooler is a simple yet efficient device suitable for all seasons, designed to cool and sometimes heat potable water.

- Below, we explain the main components and detailed operating mechanism of a water cooler. Stay with us.

1. Water Cooler Body

Regardless of whether the unit is desktop, standing, industrial, or stainless steel, all types of water coolers feature a metal or ABS body equipped with one or more cold and hot water dispensing taps.

2. Compressor:

The compressor is the heart of any refrigeration system. It compresses the refrigerant gas, increasing its temperature. The high-pressure gas then exits the compressor and moves toward the condenser for cooling.

3. Condenser:

The condenser is responsible for cooling the hot refrigerant gas and converting it into liquid form. The hot gas enters the condenser from the compressor, where its heat is transferred to the surrounding air (typically using fans), turning the refrigerant into a liquid.

4. Expansion Valve:

The expansion valve reduces the pressure of the liquid refrigerant. After leaving the condenser and before entering the evaporator, the refrigerant passes through the expansion valve, causing its temperature to drop and preparing it to absorb heat from the surrounding water and evaporate again.

5. Evaporator:

In the evaporator, the refrigerant absorbs heat from the water, cooling it and transforming back into gas.
This process is what removes heat from the water and cools the water inside the water cooler tank.

6. Cold Water Tank:

The water inside the tank remains in continuous contact with the cold evaporator coils, which lowers its temperature. The cooled water is stored in this tank and used when needed.

7. Dispenser Valve:

This valve allows hygienic cold water to be dispensed from the unit. By pressing a button or lever, cold water flows out of the tank and becomes available for use.

8. Heating System (If Available):

Some water coolers also provide hot water in addition to cold water. In such models:

Heating elements: Installed inside part of the tank to heat the water.

Thermostat: Controls the temperature of hot water to prevent overheating.

Hot water tank: Hot water is stored in a separate tank and dispensed through a dedicated outlet.

9. Safety Systems:

Thermostats: Control the temperature of both cold and hot water to keep it within the desired range.

Safety switch: Some water coolers, especially on the hot water outlet, are equipped with safety switches that shut down the device in case of malfunction to prevent damage.

This process operates automatically and continuously to ensure water is always ready for use.

Water coolers are commonly used in offices, public spaces, and homes, and due to their convenience and quick access to cold and sometimes hot water, they are extremely popular.

Types of Water Coolers

In general, water coolers are manufactured and offered in various types and models. Below, we explain each category in detail.

Industrial Water Cooler (Stainless Steel)

Large and industrial water coolers are installed in public spaces such as commercial centers, parks, shopping malls, universities, schools, sports facilities, metro stations, sidewalks, and similar locations to provide people with hygienic drinking water at suitable cold temperatures. These devices allow the public to drink water easily throughout the day and use fresh, cool water for their personal needs. Installing industrial water coolers also helps optimize overall water consumption.

These units cool water to an appropriate temperature, ensuring that everyone has access to a sufficient amount of water for personal use while preventing water waste.

By providing access to cold drinking water through industrial water coolers, people are less inclined to purchase bottled water, which contributes to reducing plastic consumption and plastic waste. Installing industrial water coolers in public places helps facility managers meet the public’s need for hygienic and pleasant drinking water. These devices also create comfortable environments where people can spend time together in public spaces while benefiting from basic amenities such as cold water.

Overall, installing industrial water coolers in public areas improves public health, reduces water consumption, and decreases the production of plastic waste such as bottled water. In addition, the body of most industrial water coolers is made of stainless steel, and due to their larger dimensions, they are capable of producing higher volumes of cold water.

Stainless steel or industrial water coolers are typically equipped with one, two, or three taps and are usually connected to the municipal water supply on one side and to electricity on the other, with a wastewater outlet included.

Buying a Water Cooler

There are many important factors to consider when purchasing a water cooler to ensure you select a suitable unit that meets your needs.

Before buying a water cooler, it is recommended to conduct thorough research and carefully review factors such as the unit type (standing or desktop), brand, quality, number of water taps, warranty, after-sales services, and other relevant aspects, while comparing different brands.

To properly select and purchase a water cooler, you should first determine the brand (such as Eastcool, Midea, Magic, Sam, Hyundai, Andranik, etc.), the model (standing or desktop), and the system type (connected to municipal water or tank-based), based on the installation location and intended use.

At the specialized DamaTajhiz collection, technical information for various water cooler models from reputable brands with original warranties is provided to ensure a smart and optimized purchasing experience.

Water Cooler Price

Water coolers vary in price depending on their type and model, so it is important to consider the price when purchasing different water cooler options.

It should be noted that extremely low-priced water coolers are not recommended, as they may be manufactured using low-quality materials that could be harmful to users’ health. Additionally, their bodies may lack sufficient durability, leading to damage in a short period and water leakage from the taps.

Therefore, keep in mind that desktop water coolers may have lower prices, but their motors are also smaller, which affects the overall durability and quality of the unit.

However, there is no need to worry about water cooler prices, as all water coolers offered by the reference and specialized DamaTajhiz collection are reasonably priced, with consumer-requested discounts already applied.

Key Factors When Buying a Water Cooler

As mentioned earlier, there are several important factors to consider when purchasing a water cooler and comparing different models and brands. These factors include:

Dual-Function Water Coolers

In the past, water coolers were designed only to produce cold water. Today, most modern water coolers are manufactured with dual functionality.

By choosing this type of water cooler, you can simultaneously supply both cold and hot water for offices or workplaces.

Hygiene Standards

If you plan to purchase a tank-type water cooler, be aware that storing water in the tank for extended periods may lead to sediment buildup and bacterial growth. Therefore, the water should be used regularly, or replaceable bottled water tanks should be used.

The selected water cooler must have an internal stainless steel tank to prevent rust from contaminating the water.

Water Cooler Capacity

The ability of a water cooler to heat or cool water within a specific time frame is one of the most important considerations.

The higher the unit’s capacity, the faster the water will be heated or cooled.
(Typically, the maximum heating power is around 500 W, while cooling power reaches up to 120 W.)

Water Cooler Body Material

Units with stainless steel bodies are generally more expensive and considered industrial-grade. For this reason, ABS material is commonly used for water cooler bodies, as it is a durable, widely used industrial plastic that is easy to clean.

Water Cooler Filtration System

Some tank-based water coolers are equipped with water purification filters.

Since filtration increases overall costs, such models are not economical for public places with high consumption and are more suitable for residential use.

Water Cooler Motor Noise

It is normal to hear the motor sound when a water cooler is operating; however, excessive noise (especially in quiet environments) can be disturbing. Therefore, this factor should be carefully considered.

To address this issue, pay attention to the noise level, quality, and brand of the compressor when purchasing a water cooler to ensure low-noise operation.

Energy Consumption

The energy efficiency label is one of the most important features that a water cooler should have. The higher the energy rating, the better.

Since the condenser and cooling motor have the greatest impact on electricity consumption, a lower motor power consumption results in a higher overall energy efficiency rating.

Differences Between Water Cooler Types

In general, the features that distinguish various types of water coolers include the following:

• Power Consumption:
  Power consumption varies across different water cooler models. Higher power consumption means greater electricity usage to produce cold water.
• Cold Water Production Capacity:
  Cold water capacity is measured in liters per hour.
  The higher the capacity, the greater the unit’s ability to produce cold water. For example, one device may produce 2 liters per hour, while another produces 4 liters per hour.
• Cold Water Temperature:
  Water coolers produce different cold water temperatures depending on the model. For instance, most Eastcool models can supply water at temperatures ranging from 5 to 10°C.
• Hot Water Capability:
  Some water coolers can produce hot water in addition to cold water for making tea, coffee, and similar beverages. This feature depends on the manufacturer and brand.
