Thermal Clothing
What is industrial thermal clothing and why is it mandatory in many positions?
Industrial thermal clothing encompasses all technical garments designed to regulate body temperature in extreme working conditions. While conventional thermal clothing acts as a passive barrier against cold, high-performance industrial thermal clothing goes further: it incorporates active technologies that intervene on body temperature in real time.
In terms of occupational risk prevention, industrial thermal clothing is recognized personal protective equipment (PPE) against the risk of heat stress. Law 31/1995 on Occupational Risk Prevention and Royal Decree 773/1997 on the use of PPE require employers to assess this risk and adopt specific measures when reference values are exceeded. Prolonged exposure to high temperatures can lead to fatigue, loss of concentration, heat stroke, and workplace accidents.
Having adequate industrial thermal clothing is not just a competitive advantage: in many sectors it is a legal obligation that can be documented before the Labor Inspectorate.
PCM Technology: The Core of Blizzcool Industrial Thermal Clothing
Blizzcool industrial thermal clothing is based on PCM technology (Phase Change Material). PCM packs contain a material that absorbs large amounts of heat energy when transitioning from solid to liquid state, maintaining a constant and predefined temperature during this process.
The result: workers wearing this industrial thermal clothing experience stable and continuous cooling without moisture, without dripping, and without variations. When the cycle ends, the packs are regenerated in a refrigerator, freezer, or cold water and are ready for the next shift.
Advantages of this industrial thermal clothing over other solutions:
- No electricity or batteries: operates completely autonomously.
- Dry garment throughout use: unlike evaporative systems, the vest does not get wet. Essential in electrical environments or those with strict hygiene regulations.
- Constant protection temperature: PCM does not lose effectiveness progressively; it acts until the phase change is complete.
- Compatible with any PPE: this industrial thermal clothing is worn under work clothing, flame-retardant suits, or high-visibility garments without interfering with any of them.
- Reusable indefinitely: PCM packs do not degrade with cycles. They are a long-lasting industrial asset.
In Which Sectors Is Industrial Thermal Clothing Needed?
Industrial thermal clothing for working in heat is necessary in any sector where operators are continuously exposed to high temperatures:
- Metallurgy, foundry, and steel industry: work near furnaces, casting, and heat treatments with radiant temperature far exceeding ambient temperature. The use of industrial thermal clothing in these environments can be crucial in preventing heat stroke.
- Welding and thermal cutting: the vest is worn under welder’s clothing, reducing heat stress without interfering with protection against sparks or UV radiation.
- Ceramic and glass industry: firing processes that generate intense and sustained heat environments throughout the workday.
- Bakeries and industrial kitchens: continuous ovens and hot production where industrial thermal clothing makes a difference in well-being and performance.
- Logistics and warehouses in summer: non-air-conditioned facilities where operators accumulate heat during full shifts of picking, loading, and unloading.
- Construction and outdoor work: direct sun exposure with effective temperatures frequently exceeding 40°C, where industrial thermal clothing acts as PPE against heat stress.
- Automotive: production lines with drying and welding booths where operators work in areas of high localized temperature.
- Industrial maintenance: interventions on hot equipment or continuous production facilities that cannot be stopped.
Blizzcool Industrial Thermal Clothing: Available Models
PCM Cooling Vest BW01 — The highest-performance model within Blizzcool industrial thermal clothing. Greater body coverage and greater PCM pack loading capacity. Designed for the most demanding environments: foundry, welding, metallurgy, and furnace processes. Compatible with use under any high-demand PPE. Available in various sizes.
PCM Cooling Vest BW02 — The versatile model in the industrial thermal clothing range. Lighter profile, designed for moderate activity in environments between 30 and 45°C: logistics, warehouses, construction, and outdoor work. Easy to put on and take off, with quick adjustment for different body types and clothing layers.
PCM Packs — The accessory that multiplies the autonomy of any Blizzcool industrial thermal clothing garment. Available separately as replacement or to have extra sets and alternate between cycles without interrupting the shift.
Frequently Asked Questions About Industrial Thermal Clothing
Does industrial thermal clothing protect against heat or only against cold?
The concept of industrial thermal clothing encompasses all technical garments that regulate body temperature at work, both against cold and heat. Blizzcool PCM vests are industrial thermal clothing specifically designed for hot environments: they extract excess heat from the body through the phase change of the PCM material, maintaining body temperature at safe and comfortable levels.
How long does the cooling effect of this industrial thermal clothing last?
It depends on ambient temperature and physical activity level. Under typical industrial working conditions (35-45°C, moderate activity), autonomy per cycle ranges between 2 and 4 hours. With a second set of packs regenerating simultaneously, the industrial thermal clothing provides continuous protection throughout the entire workday.
Is it mandatory to provide industrial thermal clothing to workers exposed to heat?
Law 31/1995 on Occupational Risk Prevention requires assessing the risk of heat stress and adopting preventive measures when reference values are exceeded. Industrial thermal clothing for heat protection is a documentable measure that contributes to regulatory compliance and can be verified before the Labor Inspectorate.
What other PPE is this industrial thermal clothing compatible with?
BW01 and BW02 vests are designed to be worn under regular work clothing, flame-retardant suits, high-visibility garments, or any other PPE. The slim profile of PCM packs does not create bulk or restrict movement, making this industrial thermal clothing a solution compatible with virtually any environment and equipment.
How long does it take for Blizzcool industrial thermal clothing to regenerate?
PCM packs regenerate in a conventional refrigerator (4-10°C) in 2-4 hours, or faster in a freezer. Freezing is not necessary: it is enough for them to reach a temperature below their phase change point for the industrial thermal clothing to be ready for the next cycle.
