Sustainable temperature control systems with CO₂ refrigerant

Unistat process circulators now backed by a 4-year warranty

Peter Huber Kältemaschinenbau SE has unveiled its next-generation Unistat temperature control systems, integrating cutting-edge technologies to deliver enhanced efficiency and sustainability. The updated Unistats now come with a 4-year warranty and offer 'Green Line' models utilising CO₂ refrigerant (R-744). These environmentally-friendly units feature zero Ozone Depletion Potential (ODP = 0), minimal Global Warming Potential (GWP = 1), and non-flammability, providing a 100% sustainable alternative to systems using synthetic refrigerants. Covering applications from laboratory research to industrial production, Huber’s range of natural refrigerant solutions is unparalleled in liquid temperature control.

Faster, more efficient processes

The new Unistats feature a reduced internal filling volume, significantly decreasing heating and cooling times. This enhancement improves ‘time-to-temperature’ and overall response times, allowing for more efficient processing. The systems are now equipped with state-of-the-art, magnetically coupled circulation pumps that deliver high flow rates for optimal heat transfer. Enhanced venting and degassing functions ensure quick commissioning and smooth, uninterrupted operation.

Enhanced safety and connectivity

Safety and connectivity have also seen major upgrades. All safety features meet or exceed performance level C standards (DIN EN ISO 13849-1). The new ‘Com.G@te DIGITAL’ module is included as standard, offering common digital interfaces and improved temperature measurement accuracy. Connectivity options can be expanded with additional modules and gateways, including the optional ‘Com.G@te PLUS’ for analogue interfaces.

Energy-efficient and space-saving design

Huber’s hydraulically sealed Unistats support wide temperature ranges without the need for fluid changes. They prevent oil vapours and oxidation of heat transfer fluids (HTF), extending the lifespan of the HTF. The systems are designed with sustainable energy management in mind, featuring low power and water consumption that translates to reduced operating costs. A compact housing design minimises the footprint, making these units ideal for space-constrained laboratories and production facilities.

Extended warranty for added assurance

Since early 2024, all Huber temperature control units, including the new Unistats, come with an extended 4-year warranty. To activate the warranty, customers simply need to register the unit’s serial number within three months of delivery.

Ideal for a range of applications

Unistat process circulators offer cooling capacities from 0.48 to 130 kW, making them perfect for demanding thermal process engineering tasks. Their versatility ensures smooth scale-up from research laboratories to full-scale production environments.
