Haydale (AIM:HAYD), the AIM-listed advanced materials and clean-technology group, said its Super-Efficient Thermal Transfer Fluid (SETTF) has restored glycol-based data-centre coolant to the thermal performance of pure water in application testing.
SETTF lifted the thermal conductivity of inhibited glycol coolant by approximately 28%, matching pure water while retaining the freeze, corrosion and fouling protection glycol provides.
Haydale has signed agreements with Liquitherm Technologies Group, trading as DC Cooling Solutions, and Levidian Nanosystems, establishing the supply chain and route to market.
The three parties are in advanced discussions with data-centre operators representing approximately 200 MW of capacity, with first installations targeted within twelve months, though the company cautioned there is no certainty these talks will convert into orders.
SETTF is the second proprietary product to emerge from Haydale's product-led strategy since its December 2024 restructuring, following JustHeat, its graphene-enabled underfloor heating technology.
Existing functionalisation capacity at the company's Ammanford site can support approximately 2 GW of data-centre capacity, equivalent to around 2 million litres of treated coolant annually, without further investment.
Using industry pricing comparators of $8 to $12 per litre, the 200 MW currently under discussion represents a gross end-market product value of approximately $1.6 million to $2.4 million, though Haydale stressed this illustrates market scale rather than a revenue forecast.
Haydale intends to establish a dedicated commercialisation venture to hold the SETTF business, funded by external capital raised directly into it, while retaining its underlying intellectual property and a controlling equity stake.
"We now have application-tested technology, protected IP, production capacity at Ammanford and commercial agreements establishing our supply chain and route to market," said chief executive Simon Turek.
Haydale expects to provide a trading update covering SaveMoneyCutCarbon and JustHeat following the end of its financial year on 30 September.
News Intelligence what this means for the company
Haydale has signed commercialisation agreements for SETTF, its thermal-transfer fluid additive, and entered advanced talks covering ~200 MW of data-centre capacity with first installations targeted within 12 months. The product restores glycol coolant's thermal performance to pure water (28% conductivity lift) while retaining freeze and corrosion protection—a technical validation that moves SETTF from lab to supply-chain stage, with existing Ammanford capacity able to support 2 GW without further capex.
- Liquitherm Technologies Group (DC Cooling Solutions) and Levidian Nanosystems now hold distribution rights and supply-chain roles; their execution on the 200 MW pipeline directly determines whether advanced talks convert to orders within the 12-month window.
- The company plans to fund SETTF via a dedicated external-capital venture while retaining IP and controlling equity—a structure that could dilute existing shareholders if external investors take material stakes, though Haydale has not disclosed terms.
SETTF represents a second product-led commercialisation path (after JustHeat) emerging from Haydale's December 2024 restructuring, but the 200 MW pipeline is illustrative only—the company explicitly cautioned there is no certainty these talks will convert into orders. The $1.6–2.4 million gross end-market value cited for current discussions is small relative to the company's need to reach positive EBITDA within ~12 months of the SaveMoneyCutCarbon acquisition; SETTF's near-term revenue contribution remains unquantified.
