Coolants engineered to stop corrosion, not just carry heat.
ET2C International supplies the ET- range of secondary refrigerants and heat-transfer fluids formulated for pharmaceutical, food, cold storage, data centre and industrial systems that can’t afford unplanned downtime.
Manufactured in China. Supplied direct.
Our ET- heat-transfer fluid chemistry is protected by a family of national invention patents, with the original formulation filed in 2002 thats over two decades of continuous protection covering the base formulation, wide-temperature bi-directional operation (a single fluid for both heating and cooling), and specialist low-toxicity variants.This sustained IP protection reflects deep, ongoing R&D investment into our unique coolant range.
Why ET2C
ET2C International is a British-owned company and the exclusive international commercial and export partner for the ET- coolant range. The products are manufactured at a single dedicated facility in China with a 20+ year production track record, holding ISO 9001, ISO 14001, and OHSAS 18001 certification. British ownership. China-manufactured. Globally supplied.
The results
Near-zero corrosion
Corrosion rates measured at up to 278 times below Chinese national standard limits. Independently tested by IMR-CAS (Institute of Metals Research, Chinese Academy of Sciences), a CNAS-accredited and ILAC-MRA accredited laboratory. Results recognised as internationally equivalent by accreditation bodies in Australia, India, the UK, EU member states, and the United States
8–10+ year equipment life
versus 3–4 years for commodity glycol, avoiding the corrosion that eats through pipes and heat exchangers.
Lower environmental impact
indirect systems reduce primary refrigerant inventory and the hazardous waste from frequent fluid disposal.
Non-flammable options available
for high-safety environments
(ET-8 series).
Better thermal performance than glycol
Engineered for consistent heat transfer across a wide operating range.
One fluid, −110°C to +340°C
across the ET- product family, grade-dependent.
Single-fluid system design
One fluid, both directions: heating and cooling across −50°C to +120°C in the same loop, replacing separate brine-and-steam arrangements and removing cross-contamination risk.
Significant long-term cost savings
fewer fluid replacements, fewer repairs,
less downtime.
Trusted by a range of client industries
Clients span pharmaceutical API production, specialty and fine chemicals, food cold storage and logistics, beverage manufacturing, professional winter sports facilities, and data center cooling. They include publicly listed companies, Fortune 500 suppliers, and operators exporting to regulated markets across more than 30 countries. The Chinese Academy of Sciences, which independently validated the ET- range's corrosion performance, also uses the product in its own facilities, a relationship that reflects both the scientific credibility and the practical reliability of the range. System deployments range from single-reactor pharmaceutical plants to 40,000-tonne cold storage facilities.
By the numbers
One fluid change. A decade of uptime.
Total cost of ownership
The fluid is the cheapest part of the bill
maintenance, repairs and replacement avoided over the life of the system.
Where it’s used
Six verticals, one engineered fluid family
Pharmaceutical and API manufacturing is our priority segment, followed by food & beverage, cold storage, industrial manufacturing, data centres and HVAC / district cooling.
Proof, not promises
Documented results from the field
A sample of the operating case studies our technical team shares with prospective clients during technical evaluation.
API plant brine/steam system replaced
Severe corrosion of reactors, heat exchangers and pipelines from a brine/water/steam system led to a full system replacement and the loss of a batch of pharmaceutical intermediates. After refilling with ET-4, the corrosion issue was resolved and the system has run without corrosion since.
500-tonne glycol system converted to ET-4
A glycol solution operating at −20 to 100°C suffered severe high-temperature corrosion within three months. Replaced with 50% ET-4 across a 500-tonne system, it has run without corrosion since the change.
40,000-tonne facility, indirect system
A 40,000-tonne cold-storage facility uses an integrated primary refrigerant plus ET-4 secondary loop. The indirect design is safer and more environmentally friendly, and corrosion has been eliminated.
