Spot Cooling Device | Ultra-Low Temperature Air Generator "Kolder" (Video Available)

A compact spot cooler that generates ultra-low temperature air with a maximum temperature difference of -75°C just by connecting compressed air.

The Kolder is a simplified spot cooler that applies the principle of vortex. Without using a power supply or refrigerant gas, it discharges ultra-low temperature air with a maximum temperature difference of -75°C (at a supply pressure of 0.7 MPa, in the case of model 190-75SV) simply by connecting compressed air. A typical application of the generated cooling air is the removal of heat generated during the processing of materials such as metals and plastics, and it demonstrates excellent effectiveness, especially in the processing of hard materials and high-viscosity substances (such as titanium alloys, stainless steel, nickel alloys, and thermoplastic plastics). Additionally, the cooling effect on workpieces and tools leads to improved cutting speeds and extended tool life, making it particularly suitable for dry cutting of magnesium alloys. Furthermore, it is effectively utilized as a cooling source for various spot cooling applications, including preventing heat-related issues in electrical control boxes and various measuring instrument boxes, cooling molds, and cooling tests for semiconductors and PC boards. *For more details, please refer to the basic information and downloadable materials at the bottom of the page.

Applications/Examples of results

【Examples of Use】 It is used for various "spot cooling" applications, from localized cooling during machining such as cutting in manufacturing sites to cooling inside boxes like control panels. 【Usage Examples】 - Spot welding: Cooling the spot weld area with cold air eliminates the need for post-processing and improves product quality. - Metal threading: The cooling air from the cold air unit increases the threading speed, prevents heat buildup, extends tool life, and improves the accuracy of the threads. - Plastic cutting: The low-temperature air from the cold air unit prevents an increase in friction heat, allows for high-speed work, and results in a clean cut surface. - Metalworking - Tapping: With -18°C cold air from the cold air unit, brass tapping can be done without using coolant. The finish is clean, allowing for the next process to be skipped.

Our company was founded in 1971 and has been introducing unique and excellent products from overseas to our customers in Japan. We handle over 10,000 items, including fittings, couplings, various valves, and check valves. Among these, we take pride in being a pioneer in the market for small plastic piping components manufactured by CPC in the United States, such as CPC couplings, which we have been proposing since 30 years ago when brass and stainless steel were the norm. These products are widely used in small devices across various fields, including general industry, healthcare, food and beverage, printing, and experimentation, due to their features of being "compact," "lightweight," and "offering a wide variety." Additionally, in the field of industrial air equipment, we have been supplying products focused on "cooling," "blowing," and "air transport" using compressed air, including the "Cryogenic Air Generator Kolder," to manufacturing sites across various sectors for many years. In recent years, we have also been focusing on new product development in different fields, including springs made from PEEK resin. In April 2018, as part of our new initiative to improve customer satisfaction in industrial piping components, we opened a satellite showroom in Odaiba displaying approximately 2,500 items.
