SlimIn is the range of ultra-slim air conditioners designed for external mounting, semi-recessed installation, or fully recessed installation, ideal for applications requiring a compact footprint and minimal protrusion from the electrical enclosure.
The CE and UL Listed certifications (for the R513A version only) facilitate market access, reduce customs barriers, and ensure greater reliability while saving time and costs.
Different installations for every space requirement
The challenge is rarely finding an air conditioner that can provide cooling; the real challenge is finding one that integrates seamlessly. In modern industrial applications—such as modular automated lines, machine tools, packaging systems, process plants, and machine-mounted electrical enclosures—the space around the structure is often already defined and non-negotiable.
SlimIn air conditioners address this requirement with a reduced-depth design that allows active cooling to be installed without modifying the enclosure layout, increasing the machine’s overall footprint, or creating interference with surrounding components.
For OEMs and panel builders, this translates into an immediate practical advantage: more compact enclosures, cleaner installations, fewer on-site modifications, and greater ease of replication across multiple units of the same machine.

Refrigerants R1234yf and R513A: efficiency, compliance and sustainability
The use of R1234yf and R513A refrigerants, combined with high energy efficiency and the reduced refrigerant charge required, helps lower resource consumption and CO₂ emissions, making the system more sustainable and environmentally friendly.
The R1234yf refrigerant features a GWP value of 0.5, significantly lower than the limit of 150 established by Regulation (EU) 2024/573, ensuring full compliance with the latest European regulations on fluorinated gases.
For applications where specific safety requirements do not allow the use of flammable refrigerants, a version using R513A is available. It features a GWP of 631, which is below the limit of 750 established by Annex IV of the Regulation.
High energy efficiency
Reduced environmental impact
No harmful effects on the ozone layer
Compliance with current European regulations
Thanks to these features, R1234yf and R513A refrigerants represent a reliable and sustainable solution for the cooling of industrial electrical enclosures.
