Commercial & Industrial ESS Coolant Pump
Commercial and industrial energy storage systems operate at higher power and for longer durations than home batteries, which means the thermal management loop must work harder and keep running outdoors for years. A commercial & industrial ESS coolant pump has to deliver sustained flow at high back pressure, survive extreme climates and never leak. The TA70E series is built exactly for that job.
The TA70E pumps are rugged, heavy-duty micro brushless DC magnetic drive pumps designed for tough outdoor conditions in liquid-cooled enclosures. With a platform flow range of 30–60 L/min and up to 30 m head, they provide reliable thermal management for C&I energy storage units, high-powered EV charging stations and data centers.

Key Features and Engineering Advantages
Magnetic Drive, Leakage-Proof Structure
An innovative magnetically driven structure operates with a static seal design, providing superior protection from mechanical shaft wear and completely preventing fluid leakage through the pump during its entire operational life.
Low-Heat, High-Efficiency Motor
The advanced brushless DC motor generates minimum heat, preventing unnecessary heat from being transferred back into the system – a critical advantage in sealed C&I enclosures where every watt of parasitic heat must be rejected by the chiller.
Adapted to Extreme Climates (-40°C to 80°C)
Designed for severe outdoor conditions, the TA70E starts reliably at temperatures as low as -40°C and operates up to 80°C. It works with pure water, industrial-grade glycols and coolant mixtures.
Automotive-Grade Electronics
Automotive-grade electronic parts withstand voltage fluctuation, vibration and temperature cycling, giving container and cabinet OEMs the field reliability they expect.
Applications for the C&I ESS Coolant Pump
- Containerized BESS – liquid-cooled utility and C&I storage containers from 100 kWh to MWh scale.
- High-powered EV charging stations – liquid-cooled supercharger piles and charging hubs.
- Data centers – coolant circulation for battery backup rooms and liquid-cooled IT loads.
- Industrial thermal management – process cooling loops, inverters and power electronics.
For compact residential and light commercial cabinets, the TA60E-B energy storage liquid cooling pump is a lighter alternative; the home energy storage cooling pump covers wall-mounted home systems.
How to Size a Coolant Pump for C&I ESS
1. Estimate the Heat Load
For a containerized system, heat load is a function of charge/discharge power and efficiency: P_heat = P_power × (1 − η). A 500 kW container at 95% round-trip efficiency generates roughly 25 kW of heat that the coolant loop must reject.
2. Calculate Flow and Head
Using Q = P / (ρ × c × ΔT) with a 4–5°C delta-T and 30% glycol coolant, a 25 kW heat load requires approximately 70–90 L/min across the whole container – usually split between two or more pumps in parallel. The TA70E’s 30–60 L/min per unit with 25–30 m head covers both single-pump cabinets and parallel-pump containers with long piping runs.
3. Plan for Redundancy
For critical infrastructure, run pumps in N+1 configuration. Because the TA70E is a brushless magnetic drive pump, hot-swapping a failed unit is straightforward and does not disturb the coolant loop.
TA60E-B vs TA70E: Which Coolant Pump Do You Need?
| Criteria | TA60E-B | TA70E |
|---|---|---|
| Best fit | Residential & light commercial cabinets | C&I and containerized ESS |
| Flow rate | 35 L/min | 30-60 L/min platform |
| Max head | 21 m | Up to 30 m |
| Voltage | 24V rated | 6-28V wide range |
| Weight | 640 g | Heavy-duty construction |
| Protection rating | IP67 | IP67 |
Choose the TA60E-B when your loop is compact, runs on 24V and needs a lightweight pump that fits inside a cabinet. Choose the TA70E when you need higher flow and head, a wider voltage tolerance, or sustained duty in outdoor and containerized installations. Both use the same leak-proof magnetic drive technology, so service requirements are identical.
Why Magnetic Drive Pumps Dominate C&I ESS Cooling
In sealed C&I enclosures, a coolant leak is not just a maintenance nuisance – it can contaminate electrical insulation, short battery terminals and take a whole container offline. Magnetic drive pumps eliminate the rotating shaft seal, which is the most common leak point in conventional pumps. With a static seal and no shaft wear, the TA70E removes that risk entirely.
Field reliability is equally important: automotive-grade electronics, dry-run and blocked-rotor protection, and a wide operating temperature range mean fewer site visits, lower operating cost and longer intervals between planned maintenance – exactly what C&I and utility operators need.
Frequently Asked Questions
Can the TA70E run on a 12V or 48V system?
The platform supports a wide 6–28V operational range, which covers most 12V and 24V auxiliary power buses in ESS cabinets. For 48V buses, contact us for compatible configurations.
Is the TA70E suitable for outdoor container installations?
Yes. With IP67 protection and -40°C to 80°C operation, the TA70E is specifically designed for outdoor containerized BESS in demanding climates.
How does the TA70E compare with the TA60E-B?
The TA60E-B is a compact 24V pump (35 L/min, 21 m head, 640 g) for residential and light commercial cabinets. The TA70E delivers higher flow (30–60 L/min) and head (up to 30 m) with a wider voltage range, making it the choice for C&I and container-scale systems. See the TA60E-B page for details.
What coolant should be used?
Pure water, industrial-grade glycols and standard water-glycol coolant mixtures are all supported. The correct mixture depends on your ambient temperature range and corrosion requirements.
