COLDER Cold Air Generator – Powerful Cooling Using Compressed Air Only

The COLDER cold air generator by Kager produces extremely cold air using compressed air only – no electricity and no additional gases required. The system operates based on the Joule-Thomson effect (adiabatic, irreversible expansion), ensuring reliable and energy-efficient cooling.

The COLDER 190-75 SV model generates for example cold air down to −55 °C when connected to a compressed air line or compressor at 7 bar with an inlet air temperature of +20 °C. Installation is simple, maintenance is minimal, and operating costs are low. They are available in 4 different versions.

Typical Applications of COLDER Cold Air

COLDER cold air is widely used for heat elimination in industrial manufacturing processes, especially for:

  • Metal and plastic machining
  • Hard-to-machine materials such as titanium, stainless steel, Inconel
  • High-viscosity materials and thermoplastics
  • Dry machining, e.g. magnesium alloys

Targeted cooling of tools or workpieces results in:

  • increased cutting speeds
  • extended tool life
  • improved process stability

COLDER is also highly effective for cooling:

  • metal molds
  • printed circuit boards (PCBs)
  • semiconductors
  • electrical control and switching components

Precise Temperature Control & Stability

The outlet air temperature is adjusted via a control screw and monitored using a thermometer or sensor. With constant inlet pressure and temperature, the COLDER maintains the cold air temperature within ±0.6 °C, ensuring maximum process reliability.

⚠️ Important: The supplied compressed air must be free of oil and moisture to guarantee optimal performance and durability. They are maintenance-free.

Product- and process-related thermal indicators by KAGER

Self-adhesive temperature indicators for reliable monitoring and documentation

Reliable temperature monitoring is a key factor in industrial quality assurance and process safety. KAGER offers a comprehensive range of self-adhesive temperature indicator strips and films with irreversible visual display – enabling clear, tamper-proof monitoring without electronics.

Two product groups are currently in particularly high demand: Tempstrip and Thermoscale. While both serve temperature monitoring purposes, they differ significantly in functionality and application focus.

🔹 Tempstrip – precise temperature monitoring at defined points

Tempstrip indicators cover a temperature range from 29 °C to 260 °C and are available as flexible strips or measurement dots. Typical applications include:

  • Manufacturing and assembly
  • Quality control and testing
  • Product development
  • Logistics and transport monitoring

They are available with 5-, 6-, 8- or 10-level scales and provide an irreversible color change, ensuring permanent documentation of exceeded temperature thresholds.

Key benefits:

  • Accuracy up to 100 °C: ±1 °C, above ±1 %
  • Easy handling, no power supply required
  • Tamper-proof visual documentation
  • Custom designs available on request
  • Supplied as strips, dots, or roll goods

🔹 Thermoscale – visualizing temperature distribution across surfaces

Thermoscale multilayer films are designed for process-related temperature profiling in a range from 150 °C to 210 °C. They are ideal for applications such as:

  • Process and simulation chambers
  • Drying ovens and machine housings
  • Pressure rollers and functional surfaces
  • Lamination, photovoltaic and bonding processes

🔬 How it works: Microcapsule color technology

Thermoscale films contain a microcapsule layer that reacts to heat by creating a permanent color gradient, ranging from light blue to deep red. Color intensity reflects both temperature level and exposure time.

Advantages:

  • Clear visualization of heat distribution
  • No measuring devices or complex setups required
  • Extremely thin – suitable for curved surfaces
  • Available as 5 m rolls or single sheets (270 × 200 mm)

🔹 One portfolio – extreme temperature coverage

Tempstrip and Thermoscale are part of KAGER’s extensive range of reversible and irreversible temperature indicators, including additional strips, films, temperature paints and specialty crayons.

➡️ In total, KAGER solutions cover temperatures from –17 °C up to +1,270 °C.

Prevent burns, fight fires – with KAGER’s smart safety solutions

Preventing Burns and Fighting Fires: KAGER’s Smart Solutions for Workplace Safety

Innovative protection against heat and fire – from warning labels to fire containment blankets

In modern occupational safety, heat protection and fire prevention are becoming increasingly important. KAGER, a German trading and consulting company specializing in high-temperature technology, offers a wide range of practical solutions for both prevention and emergency protection – including self-adhesive warning labels, pneumatic cold air curtains, and fire containment blankets (BBD).
All products are designed for easy use and contribute to safe, ergonomic, and heat-protected workplaces across industry and trade.

Visual Warning Against Burn Hazards

KAGER’s Hot-Hand Indicator and Large Traffic Light labels provide instant visual alerts wherever there is a risk of burns – such as in foundries or glass processing.

  • The Hot-Hand Indicator turns red above 50 °C, warning users of hot surfaces.
  • The Large Traffic Light changes from green (up to 50 °C) to yellow (up to 70 °C) and finally red, indicating increasing danger.

Both labels are reversible, reusable, and language-independent, offering a simple yet highly effective tool for burn prevention.

Invisible Protection: The Line-Blow Cold Air Curtain The Line-Blow from KAGER creates a thin, dry air curtain that protects workers from heat, smoke, dust, and abrasion. Connected to a compressed air system, it acts as an invisible barrier – ideal for use in industrial environments, laboratories, or cleanrooms where both safety and technical cleanliness are key.

Immediate Response to Battery Fires

The Fire Containment Blanket (BBD) is KAGER’s rapid-response tool for battery incidents and E-Mobility applications. It helps limit damage and prevent fire spread during lithium-ion battery failures.

Made from non-combustible, high-temperature fabric with vermiculite coating, the blanket withstands up to 1,300 °C, remains non-conductive, and allows the use of sprinkler or extinguishing water.
Available in multiple formats – from compact car versions to professional emergency kits – it’s an essential part of any fire safety concept.

Conclusion

KAGER’s solutions combine prevention, protection, and performance – ensuring safety where heat and fire are constant risks. Whether through visual warnings, invisible air barriers, or fire blankets, KAGER helps companies protect people, processes, and property.
