Thermal and Signaling Solutions for the BESS Industry

Across different regions and applications, Pfannenberg demonstrates the breadth of its capabilities. In North America, Pfannenberg supplies chillers and heaters for a large solar-plus-storage project in the United States, capable of supplying energy to approximately 500,000 homes annually while displacing more than one million metric tons of CO₂ emissions each year. The solution was developed in close partnership with a leading European BESS system integrator: engineered in Italy and Germany, tested in Spain, and commissioned in California. 

• IP55 protection and optional rainhood make the unit suitable for a wide range of challenging outdoor applications.
• Modbus RTU communication and fault alarm support remote monitoring and machine integration.
• Low ambient package with integrated heater enables reliable operation down to -40 °C.

• power supply from 570 up to 800 V DC to directly connect with the battery system with no need for power conversion.
• off-grid unit, to be mounted inside the cabinet or container of C&I applications.
• awarded by The smarter E AWARD 2024: Compact Chiller VLV 12 by Pfannenberg Europe - The smarter E AWARD

• inverter compressor for battery energy management during charging and discharging phase
• installation flexibility: Wall-mounted compact design or semi-recessed installation
• outdoor installation: Design for harsh and extreme environmental conditions -20°C .. +50°C (+55°C)*

_{*under certain conditions}

• suitable for built-in cabinet installation
• easy water connection on the top while electrical connection is on the bottom
• a variety of sensors offer smart control of the whole system

• Robust industry standard, thanks to steel housing and thick powder coating
• Cooling medium: water/water-glycol mixtures 
• Flexible power supply: Possible use in different voltages. E.g. 400 V 50 Hz and 460 V 60 Hz

• air flow rate up to 1000 m3/h
• protection class IP 54 / NEMA Type 12
• optimum airflow and uniform temperature distribution (natural convection of the air is supported)

• switch on control cabinet heaters or filterfans when a preset relative humidity is exceeded
• unites thermostat and hygrostat in one housing and, at the same time, monitors the relative humidity and the temperature independently of each other

• has been specifically developed for demanding environments
• can be used under extreme conditions (–40 °C … +70 °C)
• fan design with ball bearing: guaranteed long service life

• PATROL – the new generation of sounder/flashing light combinations. Three dimensional innovation
• an incorrect installation is virtually impossible
• extremely high efficiency and good penetration of acoustical obstacles significantly reduce the required number of sounders

• significantly shorter assembly and installation times
• outstanding coverage area. Achieve maximum effectivness with our signaling devices
• an incorrect installation is virtually impossible

• PYRA^® flashing light 5 J
• installation options with external lugs or internal holes
• electronic constant current regulation at 24 V AC/DC devices to avoid load fluctuations
