Flexible local cooling for expanding Swedish company
When the summer sun burns on the 4,700 m² workshop roof at the company Kvarnstrands in Småland’s Ekenässjön, 8 REXNORDIC Coolers now keep the temperature in the premises at a pleasantly cool level. Inside the workshop of the family company Kvarnstrands, 50 of the total of 95 employees work at several different machines to manufacture and sharpen top-class cutting tools for the wood industry in Europe. The machines used are CNC machines, washing machines, oil purifiers, and robots. In recent years, the business has grown, and with more heat-generating machines in the premises and with restrictions on ventilation on the facade, the indoor climate during the summer months has become a challenge for the company and its employees. Maintenance manager Alexander Sellman did careful research on which cooling solutions could work for the company’s needs – today and also in the future. -Our business is constantly developing, and we need a flexible solution for cooling the premises, says Alexander, who has worked at Kvarnstrands for 17 years. Based on changed EU regulations in the future, the choice of cooling medium was an important issue for us to take into account. Kvarnstrands took help from Rex Nordic’s technical sales advisor in Sweden, Jon Lindahl, to find the best solution for their conditions. The choice fell on 8 REX14000, which are deployed in strategic locations in the premises. -We are noticing that many companies in the manufacturing industry have the same challenges, and it is very rewarding to be able to assist with affordable solutions with the launch of the Eco series, says Jon Lindahl. Kvarnstrands was founded in 1939 in Ekenässjön and the business premises have been expanded several times since then. To be able to shop locally was an important factor in why the choice fell on RexNordic. -We prefer to shop from our neighbors and here we were able to buy the machines through Axima in Vetlanda and get good and fast help and support from a Swedish salesperson, says Alexander. At Kvarnstrands, the evaporative coolers are running throughout the working hours. And the employees have found clever ways to keep the tanks filled and maximize the cooling effect. -We exercise our fire hoses and fill the coolers directly with them, says CNC technician Violand Tiku, who also puts a few ice cubes in the water to get extra efficient cooling when the outside temperature reaches above 30 degrees Celsius. The coolers were delivered just a couple of weeks ago and the employees are already experiencing less heat stress. -Yes, there is a big difference and it is very nice with the cooler air, says Sara Vilhelmsson, CNC operator. Another advantage is that the coolers are energy efficient, the REX14000 model draws only 510W, and can easily be connected to a standard 10A outlet in the room. Violand Tiku has a REX14000 placed about 10 m away and he appreciates the coolness a lot. -It’s really great, he says enthusiastically. Previously, I only had two normal room fans in this corner, but with the coolers’ adjustable fan I can adjust the airflow myself and adapt it based on the outside temperature. Jon Lindahl sees an increasing interest in evaporative coolers in many different businesses, including in milk production and the entertainment and event industry. -These coolers really create many great opportunities for RexNordic to reach new customer groups and I look forward to continuing to develop sales, he says.

Vantaa Gym Gets Cooler and Fresher with EcoCooler
In Havukoski, Vantaa, the Vantaa Gym Club acquired a Rex Nordic EcoCooler at the beginning of summer 2024. Customers of this family business, which has been operating for over 30 years, immediately noticed from the first days that the air in the gym was pleasantly cooler and fresher than before. Vantaa Gym has a gym area of 600 square meters with a height of over six meters. The company purchased a mid-sized REX25000 model from Rex Nordic’s EcoCooler range, which has an air flow of up to 25,000 cubic meters per hour. The cooling capacity of the movable EcoCoolers is heavily based on the evaporation of cold water through a honeycomb pad. The advantages of the cooler include efficient cooling without water mist, large air flow, low energy consumption, and no installation costs. “There is a clear temperature difference in the hall when the EcoCooler is in use. Customers have praised how pleasantly cooler and fresher the air is”, says Mika Holappa, owner of Vantaa Gym. At Vantaa Gym, the REX25000 was placed on the second floor in the treatment room, from where the cooler blows into the gym through an open interior window. This way, the cooler did not need to be placed among the gym equipment or people, and the cool air spread widely in the hall as it fell down. “We really didn’t have the opportunity to acquire any other solution for our premises. We rent from the city, and in the same “hectare-sized” hall there are other businesses, so we cannot, for example, install fixed cooling solutions. At first, I thought of buying ten smaller fans scattered around the hall, but then I discovered the EcoCooler on the internet and decided to try it.” “When the sun shines strongly through the skylights, the hall has been extremely hot and, at worst, felt like “the oxygen is running out”. There is basic ventilation in the hall, but it is not sufficient in hot weather. It helps to circulate the air and push cool air down while also bringing replacement air into the room, but nevertheless, the EcoCooler has done its job. In cooler weather, I have had it on half power. When it has been warmer, the fan has been on full power.” In addition to the REX25000, Rex Nordic’s EcoCooler range includes the smaller REX14000 and the larger REX48000. They are designed for different sizes of rooms, run on standard power, and do not require fixed installation or electrical work. Water directly from the hose to the tank The REX25000 has practically been constantly connected to the water supply at Vantaa Gym, which means that cold water has been constantly flowing into the EcoCooler tank. The water has been consumed in moderate amounts relative to the benefit, and there have been no humidity problems due to the EcoCooler in the hall. The water evaporates from the EcoCooler; it does not spray or cause water mist. “In hot weather, the water is constantly on. I also tried the cooler by simply filling the tank. In that case, the tank (170 litres) used water in 8-10 hours”, estimates Holappa. The open and bright Vantaa Gym has a versatile gym with modern equipment, where professional guidance is available if desired. At Vantaa Gym, one can also purchase gym programmes as well as personal training, physiotherapy, massage, and nutrition advice. The gym also allows for boxing or focusing on stretching exercises. There is a traditional sauna in the men’s changing room and an infrared sauna on the women’s side. There is also a play area for children. “It is important for us to listen to our customers and purchase equipment according to their wishes and needs. Our gym is accessible via an app around the clock every day. One can also purchase only the services needed, even for a single visit in the middle of the night. We do not bind our customers to anything.” Vantaa Gym is located at Hosantie 2, Vantaa. Vantaa Gym Club https://vantaagym.fi
How Professional Evaporative Coolers Work?
Evaporative coolers are an essential part of modern cooling technology, especially in industrial and other large-space cooling applications. Their advantages include energy efficiency and environmental friendliness compared to traditional air conditioning systems. This article examines the operating principle, applications, and benefits of evaporative coolers, as well as the technical aspects to consider when using them. Operating Principle of Evaporative Coolers Evaporative coolers utilize the evaporation process of water to cool the air effectively. This is based on a physical phenomenon where water evaporates and absorbs heat energy from the surrounding air, leading to a decrease in air temperature. Humidification and Heat Transfer Water evaporates when exposed to an airstream, and this process absorbs heat from the air, cooling it down. Coolers use special pads designed to maximize the surface area for water evaporation. These pads are often made of cellulose or plastic, which are hygroscopic and provide a large evaporative surface. Air flows through the pads via a fan, where it encounters water. The water evaporates, absorbing heat energy from the air, thus cooling it. Energy Consumption and Efficiency The energy consumption of evaporative coolers is significantly lower compared to traditional mechanical cooling systems because the process uses natural water evaporation and does not require substantial amounts of electrical energy. The efficiency of these systems depends on the ambient temperature and humidity. They work best in dry and hot conditions where the air’s moisture content is low, as this makes water evaporation most efficient. Operational Principle Adiabatic Cooling: Air is cooled through an adiabatic process where its temperature drops as it becomes humidified. This means that the air’s thermal energy is used for water evaporation without an external energy source. Ventilation and Pressure: In the cooler, air passes through the pads via a fan. The air flowing through the pads encounters moisture that evaporates and cools the air. The fan’s role is critical as it ensures sufficient airflow through the pads and guarantees uniform cooling. Water Circulation: In evaporative coolers, water circulates continuously. Water is pumped to the top of the pads, from where it flows down and evaporates due to the airstream. The recirculation system ensures even water distribution and optimizes the cooling process. Applications in Professional Use Evaporative coolers are widely used across various industries and other large-space cooling applications where efficient and cost-effective cooling is needed. Industrial Facilities Metal Industry: In hot factory halls where temperatures can rise extremely high, evaporative coolers provide an efficient cooling solution that helps keep the working environment tolerable and safe. Automotive Industry: Assembly lines and paint shops in car factories benefit from a cooler working environment, which improves worker efficiency and reduces errors. Food Industry: Evaporative coolers are ideal for cooling large storage and production areas where temperature control is critical to maintaining product quality. Data Centers Data centers require continuous and efficient cooling to prevent equipment from overheating. Evaporative coolers offer an energy-efficient alternative that can significantly reduce cooling costs in data centers. Using adiabatic cooling, data centers can also reduce their carbon footprint, which is increasingly important as environmental regulations tighten. Agriculture Greenhouses: Evaporative coolers help maintain optimal growing conditions, improving crop yields and growth rates. Cooler air reduces plant stress and enhances their resistance to diseases. Animal Shelters: Animal welfare improves in cooler conditions, leading to better health and productivity. This is especially important during the summer months when heat stress can negatively affect animal well-being. Advantages and Challenges Evaporative coolers offer many advantages. Advantages Energy Efficiency: Evaporative coolers use significantly less electrical energy compared to traditional cooling systems because they rely on the natural evaporation process. Environmental Friendliness: Since the system only uses water and air for cooling, its environmental impact is minimal, and the carbon footprint is small. This makes them an attractive option for organizations aiming to reduce their environmental impact. Cost Savings: Lower energy consumption and simple technology mean lower operating and maintenance costs compared to complex mechanical cooling systems. Technical Considerations and Design Portable evaporative coolers are highly convenient and flexible solutions for various professional cooling needs. Their technical design and use require special attention to the following aspects: Components and Materials Pads: The pads are the central part of the cooler responsible for water evaporation. They are often made of cellulose or plastic, providing a large evaporative surface and withstanding moisture and mechanical wear. Fans: Powerful fans ensure sufficient airflow through the pads. The performance of the fans directly affects the efficiency of the cooler. Water Systems: Water systems pump water to the top of the pads, from where it flows down and evaporates due to the airstream. The systems include filters and pumps that ensure water circulation and cleanliness. Device Placement Airflow Control: Optimal airflow and ventilation are essential to maximize cooling. Portable coolers should be placed to draw in as much dry and hot air as possible for the most effective evaporation. Water Source and Quality: A clean and adequate water source is vital for the system’s operation and longevity. Water quality affects the durability and efficiency of the pads and water systems. Considering Portability Durable Construction: Portable evaporative coolers must be durable and sturdy enough to be easily moved to different locations. This means strong frame materials and well-protected components. Practical Wheels: Large wheels enable easy movement of the device and are designed to withstand various floor materials and surfaces. Easy Connectivity: Coolers are easy to connect to electrical and water sources in different locations. They have practical connections and sufficiently long cables and hoses. Impact of UV Light UV light is used in evaporative coolers to improve water quality and prevent bacterial growth. Water Disinfection: UV light kills microorganisms and bacteria in the water, reducing biofilm and slime formation on the pads. This improves the system’s hygiene and reduces maintenance needs. Pad Cleanliness: UV light helps keep the pads free from biological impurities, enhancing their evaporative efficiency and extending their lifespan. Cost Savings: Using UV light reduces the need for chemical cleaning agents and improves the system’s
