[Heat Countermeasures for Factories & Warehouses in Thailand] Suiden Spot Coolers｜Cool Air 8-12°C Below Ambient Temperature｜No Installation Work Required

Factories and warehouses in Thailand often face challenges such as difficulty installing air conditioning throughout the entire building, cool air from air conditioning not reaching certain areas, or specific work areas being especially hot. Such hot environments not only place a burden on workers but also affect work efficiency and the creation of a comfortable working environment.

USHIWAKA (THAILAND) CO., LTD. sells Suiden spot coolers, which can intensively cool a required area, for the Thai market. In addition to localized cooling for workers, they can also be used to cool heat-generating machinery/equipment and areas around servers.

Why Spot Coolers Are Needed in Factories & Warehouses

At manufacturing sites in Thailand, there are cases where cooling the entire space is difficult due to the structure of the factory or warehouse. In factories with high ceilings, large warehouses, or sites where shutters or loading entrances are opened and closed frequently, cooling the entire building would require a large-scale air conditioning system, increasing both equipment costs and power consumption.

In addition, even where air conditioning is already installed, localized heat can still occur — for example, "only this work area is hot" or "heat builds up around the equipment." A spot cooler is a device that sends cool air directly to such locations, intensively cooling only the areas that need it.

Alongside supporting heat countermeasures and heatstroke prevention for workers, improving the work environment also leads to higher work efficiency and a more comfortable workplace. Where heat is an issue in the work environment, heat countermeasures are also an important factor to consider for staff retention.

Main Features of Suiden Spot Coolers

• Cool air about 8-12°C below ambient temperature Suiden spot coolers deliver cool air about 8-12°C below the ambient temperature, intensively cooling areas that need it, such as workers or equipment. Rather than cooling the entire factory, cool air is delivered only to the required area, making it suitable for sites looking to improve localized hot environments.
  
  
• Cools only where needed Cool air can be directed straight to the point that needs cooling, such as where a worker is located or where equipment is generating heat. Since there is no need to cool the entire factory or warehouse, depending on the location and method of use, cooling can be more efficient compared to cooling the whole space.
  
  
• No installation work required — ready to use immediately The unit is equipped with casters, so it can be moved to the desired location and connected to a suitable power source for immediate use. Since no large-scale piping or installation work is required, it is easy to accommodate changes to production lines or work layouts, and the location of use can be changed as needed.
  
  
• Choose the air outlet configuration to suit the application Models are available with 1 to 3 cool air outlets, depending on the number of people or the area to be cooled. In addition to intensive cooling for a single worker, a model suited to the on-site environment can be selected — for example, delivering cool air to multiple work areas or covering a certain range.
  
  
• Uses refrigerants suited to the operating environment Refrigerants such as R32 or R407C are used depending on the model, and a suitable model is proposed based on the operating environment and required cooling capacity.
  
  Note that a spot cooler releases exhaust heat from the unit at the same time as it delivers cool air, so it is not a device for cooling an entire room. When used in an enclosed space, using an exhaust duct to vent the hot air outside is an effective measure.

Wide-Ranging Cooling — From Workers to Machinery & Servers

A spot cooler is not only a device for cooling people at hot work sites — it can also be used for a variety of localized cooling applications, such as heat-generating equipment and machinery.

• Improving the environment at hot work sites When the temperature in a work area is high, it places a greater physical burden on workers. Directing cool air straight to the required work area improves the hot environment and supports creating a workplace that is easier for workers to work in. Improving the work environment is also important when considering work efficiency and workplace satisfaction.
  
  
• Localized cooling for areas air conditioning doesn't reach Even where a factory has air conditioning, depending on the equipment layout or building structure, there may be areas where cool air does not sufficiently reach. Adding a spot cooler to such areas allows heat countermeasures to be applied where needed, without having to overhaul the entire air conditioning system.
  
  
• Cooling heat-generating machinery/equipment Around production equipment and machinery, the heat generated during operation can cause localized temperature increases. Directing cool air from a spot cooler to the area around the equipment helps support temperature management in locations where heat tends to build up.
  
  
• Cooling around servers/IT equipment Servers and IT equipment generate heat during operation. Temperature management is important for maintaining stable operation. Using a spot cooler as a supplementary measure in areas where existing air conditioning alone is insufficient for cooling can help with localized temperature management around servers or equipment.

Confirm the Effect with an About 1-Week Free Demo

"How much cooler will it actually get in our factory?" and "which model should we choose?" are things that can be hard to judge from catalog specifications alone. USHIWAKA (THAILAND) CO., LTD. offers an about 1-week free demo for customers considering the introduction of a spot cooler. Customers can use an actual spot cooler in their real work environment to confirm the cooling effect and usability before making a purchase decision.

• Installed at the actual work site to compare Before / After A demo unit is installed at the actual work site. Because it operates in the location where work is normally carried out, customers can experience firsthand how the work environment changes before and after installation.
  
  
• Temperature measured before and after use During the demo, temperature is measured both before and after the spot cooler is installed, allowing the cooling effect to be confirmed numerically as well. Checking actual measured values, in addition to how it feels, provides a useful reference for the decision to introduce it and for model selection.
  
  
• A model suited to the work environment is proposed A suitable model is considered from among the spot coolers with 1 to 3 cool air outlets, based on the number of people to be cooled, the size of the work area, and the equipment layout. Selection can be tailored to the application — for example, "intensive cooling for one person," "delivering cool air to multiple workers," or "cooling a wider area around equipment."
  
  
• On-site testing at multiple locations Because a spot cooler does not require large-scale installation work, it can also be moved and tried at multiple locations within the factory during the demo period. For example, it could be tested on the production line in the morning and around equipment in the afternoon, confirming the effect at multiple locations and helping determine the most effective installation point.
  
  Confirming the effect at the actual site before purchase helps avoid model-selection mismatches, such as "we installed it but it wasn't cool enough" or "we chose a model with more capacity than necessary."

Frequently Asked Questions (FAQ)

Q1. What can be confirmed during the free demo?
A1. A demo unit is installed at your actual factory/warehouse for about 1 week. Temperature is measured before and after use, workers can check how it feels in practice, and on-site testing is carried out in multiple areas, in order to propose a model and installation method suited to the site.

Q2. Can a spot cooler cool an entire factory or room?
A2. It is fundamentally a product for localized cooling of targets such as workers or equipment. Because the unit releases exhaust heat at the same time as delivering cool air, it is not suitable for cooling an entire space. If used in an enclosed space, please consider measures such as using an exhaust duct to vent the hot air outside.

Q3. I'm not sure which model to choose.
A3. The suitable model varies depending on the number of people to be cooled, the area, the ambient temperature, and the work environment. During the free demo, the cooling effect is checked at the actual site, and a suitable model is proposed, including the number of air outlets and the required cooling capacity.
