We protect hightech – also in your train.
Every one of us enters a tram or train carriage at some point in our lives. When we do so, there is a tonne of work being carried out beneath our feet. For instance, the 25 000 V operating voltage from the overhead power line is transformed to the voltage for operating the lighting and on-board power supply.
Protected by a sophisticated underfloor enclosure made by the caleg-gruppe. Based on a welded, riveted construction, ultra-stable steels, aluminium and stainless steel are combined with each other to address both the taxing demands of railway-specific vibration testing and weight requirements. This cabinet made by the caleg-gruppe is for protecting the converter and travelling guests, and has an assured minimum usage of 30 years.
Your one-stop supplier for hightech protection
The caleg-group is the specialist when it comes to keeping your electronics safe from harmful environmental influences.
Our enclosures and cabinets protect against:
• mechanical stress
• environmental factors (water, dust or sunlight)
• electromagnetic incompatibility (EMC)
Our cabling and test procedures protect against:
• electrical faults
Our cooling and heating solutions protect against:
With the caleg-group, you have a one-stop supplier for this type of complete protection, ensuring perfect coordination. Every product that we produce is an individual solution tailored to the unique requirements of every customer.
So that customers are safe too
More important than the protection of your electronic components is the protection of the people using your technology day in day out. In the end, despite all of our expertise in the fields of construction and production and all the standards associated with that, it is the safety of your customer that has top priority.
Because we also come up with the concept for housing solutions in addition to manufacturing them, we can also take the user-friendliness of your systems into account.
As a result, we ensure that your customer is safe and that working with your high-tech equipment is a pleasant affair.
enclosures and cabinets for electronics – direct from manufacturer
From concept to manufactured product
Design – the start of the product development process
The required features of the future product are defined right at the start during the design phase. This applies above all to the standards that the product will have to meet. Our competence extends beyond national boundaries, with DIN, ISO, UL, CA, IP, NEMA and various railway standards being part of our daily business.
The first steps towards the product solution are taken using ultramodern CAD technology (HiCAD/Inventor) and our own automated design program. The work standard of the caleg-gruppe when it comes to production technology is incorporated into the future product during the design stage too.
Consequently, an optimal price-performance ratio is assured.
Modern production lines with optimised processes
Only the most modern, CNC-managed solutions for perforating, lasering, bending, welding and polyurethane foam are used by the caleg-gruppe. In our welding and powder coating areas we make use of additional automated and partly-automated production processes. While the systems themselves play a large role, the solutions adapted to the production process are central too.
Thanks to quickly convertible machinery systems, the caleg-gruppe can guarantee enormously diverse production while manufacturing batches in optimal sizes to high quality standards. Long-standing partnerships with machinery suppliers ensure that we are able to continually develop
the machinery we have.
Surface coating – component assembly – wiring
Depending on the area and conditions of usage, various systems for surface coating and corrosion protection are derived from a base material and coating powder.
When manufacturing has been completed, the goods are put into temporary storage for additional, just-in-time handling by the customer or prepared for direct shipment.
We can also take care of component assembly and wiring based on the same standards.
Companies and factorys in the caleg-group
caleg Schrank und Gehäusebau GmbH (caleg Cabinet and Enclosure Construction) is responsible for the highly-individualised development and production of stainless steel, steel sheet and aluminium housing and cabinet solutions within the caleg-group.
roger GmbH is the semi-custom producer in the caleg-gruppe. Expanding on a broad spectrum of electrical cabinets, 19″ racks, other racks, table-top enclosures and front panels, it develops and produces customer-specific solutions.
cam GmbH builds on our existing service offering in the caleg-gruppe, adding assembly, component assembly and wiring. Development and installation of housing air-conditioning and ventilation is likewise one of its core competencies.
The caleg-group in figures
We currently have more than 400 employees working on a production space of 25.000m² across 3 sites. Our largest site, located in Calau, has a production area of over 15.000m². The site gained a new manufacturing hall in 2016/2017 featuring the latest coating and powder technologies. During the same time, the group’s machinery at our Lubsko (3.000m²) and Saarbrücken (7.000m²) sites was adjusted, with additional capacity created and increased flexibility. These investments amounted to more than €7.5 million.
The caleg-group has sales offices in France, Switzerland, the Netherlands, Austria and Sweden.
The products and manufacturing processes at the caleg-gruppe meet international standards, including: DIN ISO EN 9001:2015, UL Certification, CA certification, certification for railway welding and the Alstom painting certificate.
