GEA Refrigeration specified Hydratech’s Coolflow DTX™ for the primary chilled-water circuit supporting the new Orchard HelloFresh facility. After evaluating system requirements and performance criteria, Coolflow DTX™ hybrid glycol was chosen over traditional propylene glycol due to its superior thermodynamic efficiency and operational advantages in high-load industrial refrigeration systems.
Coolflow DTX™ vs. Propylene Glycol (PG)
- Coolflow DTX™ has the same low toxicity credentials of PG and is available with NSF HT-1 food-safe certification.
- Coolflow DTX™ is accepted and adopted by designers as a more thermodynamically efficient coolant than PG.
- Coolflow DTX™ has been ‘in circulation’ in blue-chip breweries, dairies, distilleries & data centres since 2011.
- Coolflow DTX™ at 22% v/v provides the same freeze protection and biostatic resistance to bacteria as PG25.
- Coolflow DTX™ has lower viscosity, better thermal conductivity and greater density than PG at all concentrations and temperatures.
- Coolflow DTX™ contains 15% wt. bio-based constituents and has a smaller carbon-footprint than Fossil-PG.
Hydratech supplied Coolflow DTX™ as a premixed, system-ready solution, delivered to site in a combination of bulk tanker and IBC loads — all arriving on time to meet a demanding build schedule. This supported seamless commissioning of the chilled water loop and ensured the refrigeration plant could be brought online without delay.
As SmartParc continues to expand, future factory units and processing facilities will require additional industrial cooling capacity. Hydratech’s DTX advanced thermal fluids are already specified for further phases, including new Energy Centre scope and wider chilled and frozen distribution networks across the development. With continued collaboration between SmartParc, GEA Refrigeration and Hydratech, the campus is positioned to deliver reliable, energy-efficient refrigeration performance while supporting the project’s long-term sustainability goals.
