Blechexpo Stuttgart 2025: Why Short-Wave Infrared Heaters and Evaporative Coolers Make Sense in Metalworking

Blechexpo in Stuttgart focuses on sheet metal processing, joining technology, and production processes in metalworking. One aspect that is often considered only later is the indoor climate in the production halls themselves. Large hall volumes, open doors for material deliveries and goods handling, and changing workstations along the production line make conventional heating and cooling particularly challenging. This is exactly where our solutions come in.

Heat where work is taking place, not where the air is

Work in metalworking production halls takes place at fixed and changing stations: at laser and punching machines, press brakes, welding stations, or assembly workstations. Doors are often left open for material deliveries and goods handling, while ceiling heights are frequently considerable. Conventional warm-air heating primarily heats the air beneath the hall roof—where nobody is working. Our short-wave TEL Forza infrared heaters instead target the workstations directly, such as welding stations, machining centers, or assembly stations:

• No warm-up time: immediately ready for use again whenever doors are opened for material deliveries
• Targeted rather than area-wide heating: heat exactly where employees are actually working
• Efficient even in halls with high ceilings: ideal for production halls with high ceiling levels and overhead crane runways
• Power levels from 1.5 to 12 kW: can be sized appropriately for anything from an individual workstation to a large production hall

Cooling in summer: evaporative cooling instead of conventional air conditioning

In summer, metalworking halls become very hot due to machine heat, welding processes, and solar radiation. Conventional compressor-based cooling quickly reaches its economic and technical limits in the typically large-volume, open hall environments. Our mobile adiabatic evaporative coolers from the OKM Series offer an efficient alternative:

• Significantly lower power consumption than conventional compressor-based cooling, since only water is evaporated instead of operating a refrigerant circuit
• Mobile use: can be flexibly positioned at changing workstations along the production line
• No enclosed system required: also works with open doors and permeable hall structures, which are typical in metalworking
• Can be combined with fresh-air supply: provides cooling and air exchange at the same time, which is particularly beneficial at welding and machining stations

A year-round solution from a single source

Whether winter hall heating with TEL Forza or summer cooling with the OKM Series, both systems are specially designed for large, open spaces typical of production and processing halls in the metal industry. For operators and planners, this means a year-round climate solution from a single source, without compromising on energy efficiency or investment costs.
