Description
HUBER Unistat 405 with Pilot ONE
The Unistat range inspires with unique thermodynamic properties and a range of functions to meet the highest demands. Unistat technology guarantees precise, reproducible temperature control results, the shortest possible heating and cooling times and large temperature ranges without the need for fluid change. All Unistats are fitted with the innovative
Because Unistats are hydraulically sealed, the service life of the temperature control fluid is dramatically increased by preventing oil loss through vapors and oxidation, further saving resources. Unistats are fitted with extensive safety equipment and are therefore suitable for unsupervised continuous operation. Relevant operating conditions are constantly monitored and the system is switched off if necessary or with the process safety feature the emergency cooling circuit is activated.

Frequently asked questions
What does "hydraulically sealed" mean in practice?+
The circulation circuit is closed to atmosphere rather than running through an open bath. Huber's stated benefit is that the temperature control fluid does not lose volume to vapour or degrade through oxidation, so it lasts considerably longer than the same fluid in an open bath system. It also means the unit works across the full −45 to 250 °C range without a fluid change.
What is TAC control?+
TAC is Huber's True Adaptive Control — a self-optimising control strategy that tunes itself to the connected load rather than requiring manual PID tuning. It is included at the E-grade "Professional" level supplied with this unit. Display resolution is 0.01 °C and stated stability is ±0.01 °C.
What pump performance does it provide?+
The variable-speed pump delivers up to 55 lpm at 0.9 bar through M30x1.5 male connections, with a permissible fluid viscosity of 50 mm²/s. Minimum filling volume is 1.5 litres with a 2.8 litre expansion volume — small for the capability, because there is no bath to fill.
Can it run unattended?+
Huber specifies these units as suitable for unsupervised continuous operation, with operating conditions monitored continuously and automatic shutdown, or activation of the emergency cooling circuit under the process safety feature, if a limit is exceeded. Safety class is III / FL to DIN 12876 with adjustable overtemperature protection. Whether unattended running is permitted in your lab is still an institutional decision.
What are the electrical and siting requirements?+
208 V 2~ 60 Hz, drawing a maximum of 17 A with 2 × 20 A fusing. The unit measures 426 × 327 × 631 mm (16.77 × 12.87 × 24.84 in) and weighs 58 kg (127.9 lb), runs at 62 dB(A), and is rated IP20 with a permissible ambient of 5 to 40 °C. Refrigeration is air-cooled on 0.15 kg of R1270, an A3 (flammable) refrigerant.
What is supplied with it?+
The data sheet for order number 1002.0047.01 lists a mini-USB cable (#54949), the E-grade "Professional" licence (#9496) and an M16x1 male to M24x1.5 female adaptor. Com.G@te for NAMUR analogue I/O, an external pressure sensor, metal hoses, an external sensor and thermofluid are all listed as options.
