Huber offers specialised temperature control systems capable of achieving extreme temperature cycles (e.g. from -40 °C to +100 °C) within very short timeframes. This is essential for simulating load cycles in batteries, inverters and electric motors.

Huber pumps are optimised for high flow rates. High pressure is usually only required where the cross-sections are very narrow, as pressure alone does not transfer heat.

By using precisely fitting adaptors and short, insulated hose connections.

Huber offers planning support for this. The time required depends on the specific heat capacity of the medium, the mass of the reactor and the installed heating capacity of the thermostat.

The use of insulated hoses and special insulating sleeves for the connections minimises contact with atmospheric moisture and prevents ice from forming.

Through intelligent energy management using highly efficient pumps and power components, as well as stepper motor-controlled valves that precisely adjust the output to meet demand.

As data sheets are often based on measurements taken under ideal conditions, case studies illustrate how a thermostat actually performs in a specific application (e.g. a 20-litre reactor). They provide insight into actual heating and cooling times in practice.

Long hoses increase resistance and thermal inertia. The system responds more slowly. Huber therefore always recommends the shortest possible route and large cross-sections.

The Pilot ONE saves the data in the background to an internal memory or directly to a connected USB stick.

Unimotive temperature control systems are designed for operation with water-glycol mixtures and are specifically optimised for applications in the automotive industry and e-mobility. When operating with water-glycol, operating temperatures ranging from -45 to +150 °C are possible. Unimotive systems can be expanded with various options, e.g. sensors, auxiliary pumps, bus systems and modules for flow rate control and multi-circuit operation.

Special casing insulation and the prevention of thermal bridges ensure that the outer wall remains dry even at -90 °C.

A fluid with a high heat capacity can transfer more energy, which improves the efficiency of cooling or heating.

A slight overpressure in the expansion vessel prevents cavitation in the pump and protects the thermal fluid from atmospheric oxygen.

They almost completely prevent heat transfer from the surrounding environment and stop the hose surface from icing over.

This means that less mass needs to be temperature-controlled, which improves energy efficiency and reduces the response time to setpoint changes.

To keep the mass to be temperature-controlled as small as possible, which significantly improves dynamics and response speed during temperature changes.

It reduces the system’s thermal inertia and enables faster response times in the external application.

During crystallisation, precise cooling profiles must be adhered to in order to achieve the desired grain size and purity. Even the slightest deviations in temperature stability can ruin the result, which is why highly dynamic unistats are used here.

Only through comprehensive data logging can process conditions (e.g. heating curves) be accurately transferred to larger reactors.

High pressure reduces the flow rate and generates frictional heat, which reduces the cooling capacity.

Pressure superimposition can be used to raise the boiling point of the temperature-control fluid. This allows operation at temperatures above the normal boiling point, which makes processes more efficient and helps preserve the fluid.

It offers maximum chemical resistance, is easy to clean and can withstand extreme temperature fluctuations.

The flow rate determines how much thermal energy can be transferred from the temperature-control fluid to the process per unit of time. High pressure alone is of no use if the flow rate is insufficient to dissipate the heat effectively due to bottlenecks or hoses that are too narrow.

Small components have a very low thermal mass. In this case, the thermostat must respond extremely quickly, without any time delay (dead time), in order to simulate thermal stress accurately.

Biological processes are often exothermic (heat-generating). Huber temperature control technology reacts instantly to this heat generation in order to maintain the delicate biological balance within the bioreactor.

Provided they are installed correctly and safety regulations (e.g. ventilation) are observed, operation is completely safe. Huber units using propane (R290) also have minimal fill quantities.

Natural refrigerants have a negligible global warming potential (GWP < 5) and are therefore not subject to the quota regulations under the F-Gas Regulation. They also offer excellent thermodynamic properties for efficient cooling performance.

They are maintenance-free, extremely quiet, vibration-free and operate in a completely environmentally friendly manner without the use of chemical refrigerants.

Thanks to their high efficiency, low maintenance requirements and long service life, the total cost of ownership (TCO) is usually significantly lower than that of cheaper alternatives.

This means that the refrigerants used do not damage the ozone layer (ODP = 0). All modern Huber refrigerants meet this standard.

The F-Gas Regulation governs the phased-out use of climate-damaging hydrofluorocarbons (HFCs). For users, this means that refrigerants with a high GWP (Global Warming Potential) are becoming scarcer and more expensive. Huber is therefore increasingly turning to natural refrigerants to ensure future-proof solutions.

The Global Warming Potential (GWP) value indicates the greenhouse potential. Huber uses natural refrigerants with extremely low GWP values, such as propane (R290) with a GWP of 3 or CO₂ with a GWP of 1.

There is a ban on the installation of new systems. Existing systems are often exempt for longer, but refilling them becomes extremely expensive. An early switch to Huber Green Line models is recommended.
