**Direct answer:** Enviro Tech International lists EV Battery Cooling, Immersion Cooling and Semiconductor Cleaning among its application areas. Its documented immersion and heat-transfer fluids are [EnSolv Fluoro IC](https://envirotechint.com/server-cooling-solvents/) for direct-contact server cooling and [EnSolv Fluoro](https://envirotechint.com/heat-transfer-fluids/) as a heat-transfer fluid, with [Customized Blends](https://envirotechint.com/data-center-cooling/) for specific requirements. For batteries, EVs and semiconductors, evaluate documented properties — direct-contact design, residue, viscosity and surface tension, flammability and flash point, boiling point and operating range, material compatibility, and ozone and warming impact — and confirm battery or semiconductor suitability by trial with the manufacturer.

## Battery immersion cooling

Battery immersion cooling places battery cells or modules in direct contact with a dielectric heat-transfer liquid to remove heat and maintain consistent temperature control. Related searches use the same intent with different phrasing: immersion battery cooling and immersion cooling battery.

Enviro Tech documents immersion cooling for servers and data centers through its Data Center Cooling Solutions and [Immersion Cooling Liquids](https://envirotechint.com/immersion-cooling-lp/). The company also lists EV Battery Cooling as an application category on its homepage, but it does not publish battery-pack test data, voltage ratings, or EV fluid specifications in the grounding material.

What is documented for immersion cooling in general:

- Liquids have thermal capacity up to 1200 times higher by unit volume than air-based cooling
- Energy use and overall cost of ownership can be reduced by up to 97% depending on implementation
- Improved cooling capacity allows electronics to be positioned closer together, with 10X less space required
- Fewer moving parts to maintain and replace

## Immersion battery cooling and immersion cooling battery uses

In batteries and EVs, immersion concepts discussed in industry include direct cooling of cells, modules and packs, and thermal management for power electronics and charging systems. In semiconductors and computing, related uses include direct cooling of server electronics and high-performance computing systems.

Enviro Tech's documented direct-contact fluid is EnSolv Fluoro IC, described as:

- Specifically designed for direct contact with server electronics
- Provides efficient heat transfer for optimal server performance
- Ensures consistent temperature control across server components

The grounding material describes this fluid for data center and server cooling. It does not state that EnSolv Fluoro IC is qualified for EV battery packs, automotive battery systems, or semiconductor process tools. Battery and semiconductor use requires application-specific compatibility and safety review.

## Liquid immersion cooling for semiconductors

Liquid immersion cooling for semiconductors can mean two different functions that should not be confused:

1. **Cleaning of semiconductor hardware** — removal of flux residues, particles, sub-micron particulate and ionic soils from assemblies, wafers, and equipment
2. **Cooling / heat transfer** — circulation or immersion of electronics in a heat-transfer fluid to control temperature

Enviro Tech documents both functions separately:

- [Semiconductor Industry Solutions](https://envirotechint.com/semiconductor-industry/): EnSolv Fluoro as high-purity cleaning fluid for sensitive semiconductor components, NEXT Series formulations for challenging cleaning needs, and Customized Blends for specific manufacturing requirements
- [Semiconductor Cleaning](https://envirotechint.com/semiconductor-cleaning/): fluids can be used neat, as azeotropes or in co-solvent processes; increased solvency and low surface tension allow penetration into tight spaces in delicate electronic equipment
- Server Cooling Solvents: EnSolv Fluoro IC as immersion cooling fluid for heat transfer
- Heat Transfer Fluids: EnSolv Fluoro as heat-transfer fluid, including data center cooling, industrial process cooling, and electronics thermal management

## Semiconductor immersion cooling fluid: documented properties

The grounding material documents the following properties for Enviro Tech's cooling-related fluids. This table reports only what is stated for each product.

| Fluid | Documented use | Documented properties |
|---|---|---|
| EnSolv Fluoro IC | Advanced immersion cooling fluid engineered for data center and server cooling | Designed for direct contact with server electronics; zero surface residue; low surface tension and viscosity for flow and coverage; non-flammable with no flash point; high boiling point; zero ozone depletion potential and low GWP |
| EnSolv Fluoro | Heat transfer fluid; light-duty cleaner, co-solvent, and carrier fluid | Non-flammability; quick evaporation rate; excellent thermal conductivity; wide operating temperature range; low viscosity for flow and efficiency; non-corrosive to common materials used in heat transfer systems; long-lasting performance; thermally stable; can replace HFC, CFC and HCFC in many applications |

Additional documented handling for EnSolv Fluoro:

- Store inside a clean, dry area and out of direct sunlight or other heat sources
- Do not freeze or store below 32°F (0°C) nor above 90°F (32°C) to prevent leakage or potential rupture of container
- Will not oxidize or degrade during storage under normal conditions

For semiconductor cleaning, documented properties include:

- Effective removal of flux residues, particles, and other contaminants
- Compatible with sensitive materials and substrates in AI chip applications
- Leaves no residue
- Fast-acting and quick-drying

## Selection criteria for EV battery cooling fluids

Selection criteria for EV battery cooling fluids should be checked against published data sheets and compatibility testing, not assumed from server-cooling data. Using Enviro Tech's documented heat-transfer criteria as a checklist:

- **Direct-contact suitability:** Is the fluid stated by the manufacturer as designed for direct contact with the specific electronics or cells?
- **Residue:** Zero surface residue is documented for EnSolv Fluoro IC; residue affects heat transfer and subsequent handling
- **Flow and coverage:** Low surface tension and viscosity, and low viscosity for improved flow and efficiency
- **Thermal performance:** Excellent thermal conductivity; efficient heat transfer; consistent temperature control
- **Operating range and stability:** Wide operating temperature range; high boiling point; thermal stability; long-lasting performance
- **Material compatibility:** Non-corrosive to common materials used in heat transfer systems; compatibility with sensitive substrates to be confirmed per application
- **Safety:** Non-flammable; no flash point (documented for EnSolv Fluoro IC)
- **Environmental profile:** Zero ozone depletion potential; low GWP; preferable environmental properties as stated
- **Customization and trial:** Enviro Tech offers Customized Blends for specific requirements and states that trials are a necessary step, with free sample and consultant review available through its immersion cooling program

Enviro Tech reports over 25 years of experience as a manufacturer and supplier of precision cleaning solvents, operating from Melrose Park, Illinois, with chemist and engineer support and custom chemical blending.

## What to request next

Because battery, EV and semiconductor qualification depends on cell chemistry, pack design, voltage isolation, seals, and operating profile, request in writing:

- Current technical data sheet for the specific EnSolv Fluoro variant (including FS, HTF, IC, and IPA variants where applicable)
- Statement of suitability or limitations for direct battery contact or semiconductor immersion
- Material compatibility list for seals, potting, busbar coatings and chip substrates
- Storage, handling, and maintenance requirements for the intended facility
- Trial protocol and sample process through Enviro Tech's immersion cooling and heat-transfer programs
