This system comprises an industrial electric oven with internal dimensions of 1700 × 3200 × 2100 mm, engineered to deliver consistent and reliable thermal processing for demanding applications. The key feature of this oven is that it can be transported in its assembled state, eliminating the need for on-site assembly. The oven is powered by a high-efficiency electric heating unit (2200 × 2100 × 300 mm), equipped with 3 resistance blocks (a total of 9 heating elements), providing a total installed power of 27 kW. This configuration ensures uniform heat distribution and provides sufficient energy for stable and efficient operation under continuous workloads. To optimize internal air circulation and thermal performance, the system incorporates 2 Ø350 mm impellers, driven by 2 electric motors of 1.5 kW each (2 HP). This setup guarantees enhanced airflow dynamics, contributing to homogeneous temperature distribution throughout the chamber. The oven is fully insulated using 180 mm high-density thermal panels, significantly reducing heat loss while ensuring maximum energy efficiency and complete chamber sealing. This construction supports stable operating conditions and minimizes energy consumption. Additionally, the unit is equipped with an advanced control panel featuring all essential functions and operational parameters. The interface is designed with a strong focus on user-friendliness and operational flexibility, allowing the operator to easily adjust and control the system according to specific production requirements. Why this system excels: High power output (27 kW) Bjdpfx Ajyzw Ihja Tewp Optimized airflow system (dual motor + impellers) Heavy-duty insulation (180 mm panels) User-friendly and fully functional control system Designed for reliability, efficiency, and industrial performance.

Year of construction: 2022, condition: new, machine/vehicle number: AN2301155, Atlas Copco P3500i power generator The Atlas Copco P3500i iP mobile power generator is a lightweight, efficient and reliable source of mobile power. Thanks to its high fuel efficiency and compact dimensions, the power generator is versatile for daily use, for frequent single jobs, typically for power tools as an inverter power generator or as an emergency generator. With good sound insulation, the emergency generator is very quiet and hardly louder than an electric razor. The emergency generator is equipped with a large fuel tank and therefore runs up to six hours before it needs to be refueled. Despite the large fuel tank, the emergency generator is compact and light enough to be transported across construction sites or stowed away to save space. The intelligent, variable speed control, together with the option of parallel operation, results in an efficient power supply with minimal fuel consumption, as the engine speed is adapted to the current load conditions.
