Refrigerant
Cosmotec, with its Protherm range, offers a wide selection of air conditioners designed to meet different requirements, both for electrical enclosures in industrial applications and for shelters and cabinets used in telecommunications, power distribution, and other sectors. The growing need to reduce energy consumption has led to the development of highly efficient air conditioning units without compromising robustness, reliability, and compactness.
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.
Suitable for all temperature conditions
Designed for both Indoor (CVE/CVY) and Outdoor (CVO/CVH) installations, covering the full range of application requirements. The wide operating range allows installation in virtually all industrial environments and ensures reliable operation even in outdoor applications with extreme ambient temperatures.
Protection: IP55, Type 12/4/4x
The widest range on the market
Cooling capacity
From 1.000 to 20.500 BTU/hr
Power supplies
115V, 230V, 400V, 460V
Sequencing and remote monitoring
Sequencing
In some critical applications, system redundancy for air conditioning is required. To meet this critical need, two Protherm air conditioning units can be networked together to manage:
- automatic rotation, to balance operating hours
- mutual support in cases where there is an alarm on a unit preventing its operation or the cabinet temperature exceeds the support unit's temperature threshold
Remote monitoring
Air conditioners can be connected to a Modbus monitoring system to allow for direct data exchange with the air conditioner. This enables the saving of operating parameters and the rapid identification of potential problems for quick service activation.
Easy to install
Protherm units are equipped with a new connection system that makes installation faster and easier, especially for UL-certified models. The system consists of a power connector, a signal connector and, where applicable, a dedicated connector for switching the supply voltage from 460V to 400V.
- Greater ease of identifying the electrical connection to be made (component functional verification procedure during unit start-up)
- No need to open the unit (installation and/or replacement/cleaning of the filter accessory via magnetic support)
- Easy access to the electrical connection
- Reduced time required to carry out installation activities
(two inserts for easier positioning and fixing of the unit) - Standardisation
- The cut-outs will remain unchanged compared to previous models
XCB: The intelligent controller from Cosmotec
The XCB electronic controller is the technological core of Cosmotec air conditioners.
Designed by Cosmotec, XCB enables advanced unit operation management, improving efficiency, reliability, and integration within industrial systems.
Thanks to XCB control, Protherm air conditioners are not limited to just cooling the electrical cabinet, but become an integral part of the plant management system.
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.
