Unistats – for tight temperature control

The Tango Nuevo cannot be compared with conventio-

nal temperature control technology. It is a Unistat; the

smallest of its kind.

When a temperature control system has a wide tempe-

rature range, and is capable of high cooling capacities

in spite of its small size, it can be used as an all-purpo-

se unit in Research and Development applications...

When the same technology and functions can be

scaled up to larger capacities, so that it can also be

used for Industrial applications...

When a temperature control system can change with

breath-taking speed to precisely reach its setpoint

without overshoot, consistently...

It can only be a Unistat.

UNISTAT - Tango Nuevo

further development of

The temperature control application in the foreground

The international Tango Club (Unistat users across the

whole world) shed light on the trends of tomorrow. The

range of functions has been increased, and easy control

has revolutionised operation. New functions have been tes-

ted and their effectiveness proven. Every function of the

Unistat has been subjected to many tests without compro-

mise on applications and in industry under the quality spot-

light by experienced users.

Our improvements in pump technology that have increased

HTF fl ow rates has resulted in tangibly improved heat

transfer to and from the application. Predictable and repea-

table results and previously unachievable response times

to changing temperature loads produce a clearly greater

Return on Investment (ROI), further improved by the mini-

mal operating costs of the Unistat Principle.

In 1988 the fi rst generation proved the concept of the Uni-

stat Technology. The second generation consolodated and

led the growth of Unistat Technology into industry.

The Third Generation is refi ned, more effi cient and more

responsive, gives tighter control and is easier to use.

the proven UNISTAT Principle

picture 3: the unistat principle

C D

picture 1: open baths

picture 2: closed circuits

BA

Conventional baths and circulating chillers operate with a hydraulically open bath.

With open bath technology (picture 1) the bath fluid is

open to atmosphere and un-pressurised, regardless

of whether the temperature control is internal (A), or

external (B). During external temperature control (B)

the level must be controlled in two locations.

In typical externally closed temperature control

(pic.2) where the object is directly (D) or indirectly

(C) in contact with the heat transfer medium, the

atmospherically open bath is also used to contain the

expansion and contraction in HTF volume as the fluid

heats and cools.

The Unistat principle minimal HTF volume and increa-

sed thermal transfer abilities through higher HTF fl ow

rates, reduced HTF pressure and highly effi cient heat

exchange surfaces increases the system‘s speed of

response to changes in demand. Unistats have the

most rapid ramping rates capable of cooling rates of

more than a hundred Kelvin per hour. For comparisons

in cooling power densities (Watt/litre) please refer to

DIN 12876.

Expansions-gefäss

Expansions-gefäss

Unistats embody capacity and dynamics.Small in size, big in power.

The Unistat System (Pic3) combines the effi ciencies of

effective thermodynamics and modern microelectro-

nics, making it a highly effi cient alternative to open

bath temperature control technology. Unistats are

circulating thermostats with hydraulically sealed HTF

circuit with an expansion tank (E) to allow for and con-

tain HTF volume fl uctuations.

The expansion tank can be isolated to enable the cont-

rol of open-external application were the expansion and

contraction of the fl uid HTF takes place in the „open to

atmosphere“ application. Being hydraulically sealed

they can be located below or above the application.

UNISTATS

Unistats create space

A compact machine is one that is small with no loss of

power. This is measured with the ratio watts/meter³.

At every temperature the Unistat is the most compact.

To control the smallest process`s up to production volumes. Tempera-

tures from -120°C up to 400°C. Over 60 models, in sleak tower

housings, or fl at-build, with cooling capacities from 0.7kW to 130kW

for fl exible scale-up in Research, Kilo-labs, Mini-plant, Pilot-Plant, and

Production. While the Unistats grow with the application, their

operation and the Unistat Principle remain the same.

Protecting the Environment

Made from recyclable materials with an option to have

100% environmentally refrigerants, consuming 1/3 the

water of conventional systems (water-cooled units) and

an energy management system to keep electrical

power consumption to a minimum, the Unistats are

truly environmentally friendly.

Precise, Responsive

Comprehensive Safety Functions and Features

Unistats handle temperature control applications – remotely, safely, and while opera-

ting continuously. Overtemperature setting, setpoint – and alarm limits are can be set

according to the conditions of the application to be controlled. The temperature and

pressure sensors can be calibrated and the microprocessor controller monitors the

operating status. VPC (Variable Pressure Control) monitors the maximum pressure in

the fl uid loop. Passive components ensure a extraordnarily high order of reliability. In

case of emergency, the Unistats can be electrically isolated. For critical processes an

optional additional “emergency cooling system” can be activated.

True Adaptive Control (TAC)Self-optimising temperature control

Varying research criteria and process demands change

the thermal load on the temperature control system.

What does not change is the requirement for good

control.

The solution is “TAC” which has the capability to auto-

matically change with those demands, By building a

multi-dimensional model of the process, the TAC is able

to automatically adjust its PID parameters to cope with

and respond rapidly to sudden changes in the process.

Operating in both “Jacket” and “Process” control, TAC

provides responsive and close control. Rapid changes

with no overshoot, that is what TAC brings to the pro-

cess…automatically and under all conditions.

User defi ned response rates allows for dampened or

rapid response. If TAC is not required, the user can

manually adjust the PID parameters.

Maximum HTF fl ow, Minimum HTF pressure

Improved pump design together with reduced

internal fl ow resistance gives higher HTF fl ows

with lower HTF pressures meaning more

effi cient thermal transfer and faster ramping of

the process for the same power.

Bench-top and fl oor standing Unistats that use

the new “M24” pump connections are

supplied with “M16” adaptors to allow for

convenient fi tting to existing systems using

“M16” fi ttings.

Variable Pressure Control (VPC)

The pressure control with controllable soft-start

VPC was developed to protect glass reactors from damage

caused by high fl uid pressure. VPC also compensates for changes

in viscosity as heat transfer fl uid is heated and cooled. Unistats

with a cooling capacity up to 2kW have a variable-speed pump

motor with soft-start, and using a pressure sensor can control

their maximum fl uid pressure. Unistats with larger capacities (as

an option) can control the pressure using a pressure sensor and a

stepless bypass.

Minimal pressure, maximum fl ows, optimal heat transfer. VPC

allows enables the best operation while remaining inside the defi -

ned pressure limits of the application.

The programmer

Single temperature changes can be realised using the linear

ramp function. The easy to use programmer, with 200 steps,

is available for more complex temperature requirements. Indi-

vidual steps can be pieced together to form a suitable profi le.

Each step of the program can be selected to be either tempe-

rature- or time- stable. For each step, additional functions

(Potential Free contact, Analogue Interface, temperature

control mode) can be activated or deactivated.

Non-linear Ramp Function (NLR)

Especially for crystallisation processes, non-linear temperature

profi les allow higher purity crystals to be produced. Instead of

using the temperature programmer to piece together discrete

rectangular or linear ramps, e-functions can be used to defi ne a

continuous setpoint form.

The diagrams shows the high precision of the e-function (be-

low) in contrast to a linear ramp (above, with 6-steps).

The ComBox – Easy to talk to

The ComBox offers interfaces to the NAMUR Standard.

This makes the communication possibilities of the Nuevos

even more fl exible. The ComBox can be removed and

connected via one single data cable. This has the advantage

that the ComBox can be integrated in a process control

system with the minimum of cabling.

The standard version of the ComBox has the following

interfaces:

Coolnet® – unique valve control

In refrigeration equipment, refrigerant is controlled

by a metering valve. Unistat refrigeration works

with a CoolNet® stepper-motor controlled expansi-

on valve, that has been produced in the Tango Fac-

tory since 2002. The valve opening is precisely

controlled at between 0 and 600 steps, with a reso-

lution of 0.005mm/step. This allows the CoolNet to

achieve the optimal evaporator fl ow, and highest

possible cooling capacity at each working tempera-

ture. Precise and reproducible control for tempera-

tures down to -130°C.

information during thermoregulation. Clear and easy to read,

information such as the process temperature, internal (jacket)

temperature, pump pressure, safety relevant data and much

more is displayed. The unique Easy-Control menu operation:

this is supported by the alphabetical arrangement of the

menu functions. Language options currently available are;

German English, French, Italian, Spanish and Russian (Cyrillic

script). Administrators can limit the available functions into

individual user menus. Settings can be entered via the touch

screen, the soft keys, the rotary encoder or a combination of

them.

One controller for all Unistats. The controller can be updated

at any time using the most modern Flash technology. The

modular concept convinces in the case of service through

SpyLight

SpyLight is software for the visualisation and

documentation of process relevant data. The

communication can be via RS 232, RS485 or

TCP/IP. The installation is simple. SpyLight

requires very little disk space and is simple to

use. The logged data is displayed against

time. The axes can be scaled as requred. The

zoom function allows easy evaluation of

short time frames.

SpyWatch

SpyWatch is based on the SpyLight software

but offers more features. Installation and

operation is identical. SpyWatch can operate

up to 10 channels simultaneously. Each

channel is independently documented and

the graphic options can be confi gured as

required. SpyWatch allows the user to ussue

the following instructions to the unit:

– Set point

– Change from jacket to process temperature

– Start/Stop

SpyControl

SpyControl is software which contains the

functions of SpyLight and SpyWatch. An

additional point is that it offers the possibility

to control one or more machines with a pro-

grammer. The user can give temperature

programs for the machines, which then auto-

matically run. The segments of a temperatu-

re control program can be input in a user

friendly manner using the so called Tempera-

ture control-Xplorer which is a module of

SpyControl. The temperature control pro-

grams so produced can be modifi ed or chan-

ged and archived. The basic course of a tem-

perature control program can also be display-

ed graphically.

Spy-Function for on-board Service

The spy function integrated in all programs

enables simultaneous recording of machine

parameters allowing a simple diagnosis in the

event of a problem. The data to be displayed

can be selected by the user. Text can be ad-

ded to every curve. Once the curve has been

generated quick support and effi cient diagno-

sis is available.

Tango Nuevo - exothermic reactions

The curve shows the rapid response of the

Tango Nuevo. The 1 litre reactor content

starts at 0°C and within about 7 minutes re-

ach 20°C. The DW Therm (jacket) temperatu-

re increases at 10 K/min. Despite the steep

temperature gradient, the HTF is not

stressed, low watts/cm² on the heater sur-

face guarantees this. At 20°C the exothermic

reaction is simulated using an electric heater.

The HTF temperature drops at about 4 K/min

to draw the heat out of the exothermic reac-

tion. The process temperature is caught

within 1 minute, and has increased by less

than 4 Kelvin. The 12 Kelvin temperature

difference quickly brings the process tempe-

rature back precisely to 20°C. The heater was

switched off after approximately 12 minutes.

Tango Nuevo - performance data

The curve shows the performance of a Tango

Nuevo working with a 1 litre reactor. The

performance is enhanced with M24x1,5 ho-

ses. The higher fl ow improves the heat trans-

fer coeffi cient on the surface of the reactor.

The combination of high fl ow and low pres-

sure, yields both performance and control

benefi ts. Process temperature gradients of

12 K/minute are achieved due to the optimal

combination of low internal volume, optimal

circulation due to the larger M24x1,5 hoses.

The Tango Nuevo using M16x1 hoses cooling

from 100°C to -30°C takes 150 minutes. With

M24x1,5 hoses it takes only 64 minutes to

do the same job. This brings a 60 % perfor-

mance improvement.

The facts are clear a circulator with only 700

watts cooling power achieves process tem-

perature gradients of 12 Kelvin per minute in

a 1 litre reactor, this represents the ultimate

thermoregulation performance. Power is

nothing without control, the process tempe-

rature quickly reaches its set point and re-

mains there perfectly stable.

Unistat 405 - power and control

The cooling power is transferred optimally

from the unistat 405 to the process. The

combination of power and control is evident.

The near vertical curves between 20°C and

-30°C show energy being pulled from the

reactor and the precise control at -30°C

show the thermodynamics and control are

working together as one. Performance of

this kind is only possible in a low volume

hydraulically sealed Huber Unistat.

The combination of power and control is evi-

dent in the curve shown above. Process tem-

ved due to the optimal combination of low

internal volume and optimal heat transfer. This

is achieved with the „Delta T“ limiter set at

25 Kelvin to protect the glassware.

The True Adaptive Control (TAC), which conti-

nually learns and adapts illustrates tight control

on a larger volume.

Unistat 650w H96 - exothermic reaction

The curve shows the performance of a

Unistat 650w working with a Huber RG

12 kW resistance heater. The True Adaptive

Control (TAC), continually learns and adapts.

Illustrated here, a sudden load of 12 kW was

switched on and the TAC responds perfectly

to return the jacket temperature back to

20°C within a matter of a few minutes. This

is a perfect example of both power (65kW)

and control. Bring on the competition!

Case studies

The case studies were carried out with reac-

tors from current product lines. A unique and

ever growing data bank has been created

with reproducible results. With many reac-

tors from the worlds leading manufacturers

in-house we have the ability to carry out

performance tests with differening HTF´s

and accessories with glass or steel reactors.
