EnglishHow DC Airco Supports Battery Thermal Management
Updated
DC Airco supports battery thermal management with air-to-air and liquid-to-liquid HVAC units that both cool and heat battery packs, sized from roughly 0.5 kW up to 8.5 kW of cooling and running on high-voltage DC inputs such as 630/350 Vdc. That combination fits electric mobility, e-storage, and heavy-duty or off-highway equipment where the pack has to stay inside a safe temperature window across a wide range of ambient conditions. If your battery system runs on a different voltage or needs a cooling capacity outside that band, the standard catalogue may not cover it and a custom unit is the relevant path.
What battery thermal management has to do
A battery pack only performs and lasts within a limited temperature range. Too hot, and you risk accelerated degradation or, in the worst case, thermal runaway; too cold, and usable capacity and charging speed drop. Thermal management is the job of holding the pack near its target temperature by removing heat when it builds up and adding heat when the pack is cold.
DC Airco's role is supplying the HVAC hardware that does this — the cooling and heating unit, not the battery management system itself. The company describes itself as designing and producing HVAC and battery thermal management solutions, offering both standard and custom products.
The product series relevant to batteries
The catalogue lists several series. The ones most directly tied to battery and equipment thermal management are:
| Series | Configuration | Cooling | Heating | Heating options | Primary voltage |
|---|---|---|---|---|---|
| DC6000 / DC6001 | Liquid to liquid, monoblock | 3 – 8.5 kW | 2.1 – 6.9 kW | Heat pump | 630/350 Vdc |
| DC12000 / DC12700 | Air to air, monoblock | 0.5 – 5 kW | 0.5 – 4.2 kW | Cooling only, electric heating, heat pump, heat pump + electric heating | 630/350/48/24 Vdc |
| DC13000 / DC13500 | Air to air, monoblock | 0.5 – 5 kW | 0 – 1.5 kW | Cooling only, electric heating | 630/350/48/24 Vdc |
| DC24000 / DC24001 | Air to air, monoblock | 0.5 – 7 kW | 0 – 4.5 kW | Electric heating | 400 Vac |
Two distinctions matter when choosing:
- Liquid to liquid vs. air to air. A liquid-to-liquid unit (DC6000) transfers heat between liquid circuits, which suits packs or systems already using a coolant loop. Air-to-air units (DC12000, DC13000, DC24000) reject or draw heat from air, which is simpler when there is no liquid loop.
- Cooling only vs. heat pump vs. electric heating. If the pack only needs to be kept from overheating, cooling only is enough. If it also has to be warmed — for cold starts or cold-climate operation — you need a heating option, and a heat pump is the more efficient choice where it is offered.
Voltage and application fit
The DC12000 and DC13000 series accept 630/350/48/24 Vdc on the primary side, which covers both high-voltage traction packs and lower-voltage systems. The DC6000 is listed at 630/350 Vdc only, and the DC24000 runs on 400 Vac, pointing at rolling stock rather than a DC battery bus.
DC Airco positions these products across e-mobility, battery/equipment, defence and rescue, truck and mining, and rolling stock. The company has also announced high-voltage thermal solutions up to 850 VDC for off-highway and heavy-duty vehicles, presented at iVT Expo Cologne 2026, and railway HVAC and thermal management for rolling stock at InnoTrans Berlin 2026. Those announcements indicate the direction of the high-voltage range rather than confirmed catalogue specifications, so treat the 850 VDC figure as a stated capability to verify for a specific project.
How to decide whether DC Airco fits your case
Work through these conditions:
- Identify your heat load. Estimate the cooling capacity the pack needs. If it falls within 0.5 – 8.5 kW depending on series, a standard unit is plausible; if it is well outside, ask about custom products.
- Check your supply voltage. Match it against the primary voltage column above. A 48 Vdc or 24 Vdc system points to DC12000/DC13000; a 400 Vac system points to DC24000.
- Decide whether you need heating. Cooling-only is sufficient in warm climates or for packs that self-heat. Cold-climate or cold-start duty needs electric heating or a heat pump.
- Decide liquid or air. If your system already has a coolant loop, a liquid-to-liquid unit avoids adding an air path; otherwise air-to-air is the simpler integration.
- Confirm the application class. E-mobility, e-storage, defence/rescue, truck/mining, and rolling stock each map to particular series in the catalogue.
If steps 1–5 all land inside the listed ranges, a standard series is the starting point. If any of them falls outside — unusual voltage, much larger heat load, or a non-standard form factor — DC Airco's custom product line is the relevant route, and the unit catalogue is where to check exact model numbers before specifying.

The Unit Catalogue and Full Catalogue on dcairco.com list the individual models behind each series, which is where you confirm the exact cooling, heating, and voltage figures for a given part number rather than relying on the series-level ranges above.
