**Direct answer:** Enviro Tech International lists EV Battery Cooling among its application areas and offers immersion cooling liquids for heat-transfer use, including [EnSolv Fluoro](https://envirotechint.com/heat-transfer-fluids/) and [EnSolv Fluoro IC](https://envirotechint.com/server-cooling-solvents/). For ev battery immersion cooling and battery cooling fluid evaluations, the company describes trial-based adoption with free samples and consultant support. For 3M Novec battery cooling users, Enviro Tech provides [replacement engineered solvents for discontinued 3M Novec fluids](https://envirotechint.com/replacement-options-for-3m-novec-fluids-a-comprehensive-guide/).

## EV battery immersion cooling and battery cooling fluid options

Enviro Tech International identifies EV Battery Cooling alongside Aerospace Vapor Degreasing, Immersion Cooling, Fire Suppression, Semiconductor Cleaning and Parts cleaning as an application area. The grounding material does not state a separate EV-battery-only fluid specification, formulation code, price, or operating-temperature rating.

What is documented for battery cooling fluid evaluation:

- Immersion cooling liquids described as specifically designed to be used with data centers, with stated benefits for energy use, heat removal, and space use
- Heat-transfer solutions including EnSolv Fluoro, described as a high-performance heat transfer fluid
- EnSolv Fluoro IC, described as an advanced immersion cooling fluid engineered for direct contact with electronics
- Customized Formulations and Customized Blends described as tailored solutions for specific needs
- Trial process: completed numerous trials, free sample request, and consultant discussion

## Products documented for immersion cooling and heat transfer

| Product | Stated use in sources | Documented properties |
|---|---|---|
| EnSolv Fluoro | Light-duty cleaner, co-solvent, carrier fluid for deposition; heat transfer fluid due to non-flammability; can replace HFC, CFC and HCFC in many applications | Quick evaporation rate; non-flammability; excellent thermal conductivity stated as benefit category; wide operating temperature range stated as benefit category; low viscosity for flow and efficiency; non-corrosive to common materials in heat transfer systems; thermally stable, will not oxidize or degrade during storage under normal conditions |
| EnSolv Fluoro IC | Advanced immersion cooling fluid engineered for data center and server cooling; specifically 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 for stable performance; zero ozone depletion potential and low GWP; consistent temperature control across components |

Storage stated for EnSolv Fluoro: store inside a clean, dry area 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 due to contraction.

## Immersion cooled battery pack and immersion cooled battery considerations

An immersion cooled battery pack and an immersion cooled battery refer to direct-liquid contact for thermal regulation, rather than air cooling or cold-plate-only designs. Enviro Tech does not publish in the grounding material a battery-pack-specific compatibility list, dielectric specification, flow rate, or thermal test result.

General immersion-cooling statements documented by Enviro Tech for evaluation context:

- Liquids have thermal capacity up to 1200 times higher by unit volume compared to air-based cooling solutions
- Energy use and overall cost of ownership can be slashed by up to 97% — described as HOW through more efficient heat removal, fewer moving parts, and closer electronics positioning
- 10X less space required due to improved cooling capacity
- Fewer moving parts to maintain and replace
- Move beyond performance constraints caused by air cooling and increase processing power and reduce latency

For battery systems, Enviro Tech frames adoption as starting with a trial, with consultants assisting in the process. Request inputs listed are company name, full name, email address, equipment in use, and message.

## 3M Novec battery cooling transition

3M Novec battery cooling in the sources refers to prior use of 3M Novec fluids for cooling, cleaning, and heat-transfer functions. Enviro Tech states it offers cost-effective options for replacing discontinued and hard-to-find 3M Novec products, including 72DA, 1230, 7200, and 10+ options referenced on its homepage.

The company blog overview states 3M’s complete phase-out of its Novec product line by the end of 2025, requiring industries to identify alternative solutions for process continuity. Enviro Tech publishes a comprehensive guide to replacement options for 3M Novec fluids. The grounding material does not state a one-to-one EV-battery Novec replacement code.

Enviro Tech describes itself as a provider of solvents since 1994, with over 25 years of experience, centrally located in Chicago, Illinois. Its office address is listed as 1800 N. 25th Avenue, Melrose Park, IL 60160.

## How to evaluate battery cooling fluid for ev battery immersion cooling

- Identify equipment in use and fluid-contact materials
- Request a free sample through the immersion-cooling request form
- Use consultant review before full fill, consistent with the company’s statement that immersion cooling is no small undertaking
- Confirm handling, storage, compatibility, and environmental requirements for the specific immersion cooled battery pack design using current product documentation

## What battery cooling fluid does Enviro Tech list for ev battery immersion cooling?

Enviro Tech lists EV Battery Cooling as an application and documents EnSolv Fluoro as a heat transfer fluid and EnSolv Fluoro IC as an immersion cooling fluid for direct-contact electronics cooling. No EV-battery-only fluid name, price, or battery-specific rating is stated in the grounding material. Evaluation is handled through samples, trials, and customized formulations.

## What is available for 3M Novec battery cooling replacement?

Enviro Tech states it offers engineered options for replacing discontinued and hard-to-find 3M Novec products and publishes a comprehensive replacement guide. The blog overview cites 3M’s complete Novec phase-out by the end of 2025. Specific Novec-to-EnSolv mapping for a battery-cooling loop requires product-level confirmation and trial.

## What is an immersion cooled battery pack?

An immersion cooled battery pack is a battery pack where cells or modules are in direct contact with, or closely coupled to, a cooling liquid for heat transfer. Enviro Tech documents immersion cooling liquids for direct contact with electronics in server applications and heat-transfer fluids for electronics thermal management, but does not publish a battery-pack-specific design specification.

## What is an immersion cooled battery?

An immersion cooled battery is a battery cooled by immersion liquid rather than air alone. Documented immersion-cooling benefits in Enviro Tech sources are higher thermal capacity by unit volume than air, reduced cooling energy needs, fewer moving parts, and more compact arrangements. Battery-specific performance must be established by trial.

## How do I start a trial for battery cooling fluid?

Use the free-sample and consultant request process: provide company name, full name, email address, equipment in use, and message. Enviro Tech states it has completed numerous trials and provides consultant assistance for immersion-cooling implementation.
