From Cold to Hot...No compromisesregar d ing temperaturetestsThe test chambers of the WT seriesare both highly effective and econo -mical. They are equipped with everythingwhich is required to performcold-heat tests in extreme rangescom plying with the relevant standards.Due to their compact dimensionsthese chambers are perfectly suitablewhere space is limited in factoriesand laboratories.The mainadvantages . . .2compact designeasy operationlow noise levelbeneficial price / performanceratioplug-in design, connection toshock-proof socketlow connected load3.5’’ TFT-colour touch panelwith simple, menu-guideduser interfaces as a convenientinterface with the operator(no programming knowledgenecessary)USB and Ethernet interfacehigh-precision temperatureconditionsnetworking with other testsystems possibleremote control and remotemonitoring possible viaintranet or internetintegrated service informationsystemlow energy consumptionApplication . . .The test chambers allow reprodu -cible temperature tests to be performedin all areas of research, development,production and qualitycontrol.Regardless of the form and composition of the test specimen, efficient,even temperature control and climatisationin the test space guaranteehigh temperature constancy, whichin turn ensures accurate test results.Functional principle...An airstream conditioned to precisely the required set value ispassed constantly through the testspace. Components for processingthe air are located in the circulatingair duct installed in the rear wall ofthe test chamber. The symmetricalair circulation system guaranteesoptimum circulation.The circulating air is returned aboveand below the test space and flowsthrough a heat exchanger in whichit may be cooled if necessary. Anelectric heater warms the circula -ting air. An axial fan with externalmotor, mounted centrally in therear test chamber wall, blows conditionedair back into the testspace, providing intensive air circulation.Every electrical functional circuit isequipped with its own safety facilitywhich shuts down the functionalcircuit affected or the entire testchamber in case of a malfunction.The electrical system complies withthe approved state of the art in thefield, the safety regulation ”Elec -trical Systems and Facilities“ (BGVA3) as well as with the relevant VDEregulations. All test chambers fulfilthe EMC, low-voltage and machinerydirective.The hermetic refrigeration circuitsoperate with environmentally friendlyrefrigerants free from chlorinewithout any ozone-depleting potential(CFC-free).The 32-bit control and monitoringsystem of S!MPAC* ensures controllingof temperature.Networking. . .The units are compatible with theS!MPATI* software package and canbe integrated into their networkingenvironment. (data logging opera -tion in S!MPATI*).

. . . The Complete Temperature SpectrumDesign featuresThe test chambers are designed ina modular system and are ready tobe plugged in. The stainless steeltest space is welded vapour-tightand easy to clean.Its environmentally friendly insulationfree of asbestos and CFC guarantees the best possible insulationvalues and, hence, the lowestpossi ble operating costs.Moreover, the test chambers areequipped with an adjustable safetycut-out against high temperatures(test specimen protection). Anyalarm is issued visually. In addition,a potential-free contact is available.All unit sizes have one access portmade of low thermal conductivitymaterial. It is positioned in the righthand side of the chamber, and maybe used for inserting measuring andcontrol cables, other supply connectionsor supplementary equip ment.Standard design . . .digital measuring and controlsystem S!MPAC*3,5’’ TFT-colour touch panel forconvenient entering of fixedvalues and programs with graphicrepresentation of the targetand actual values, runtime, etc.S!MPATI* Program Toolrefrigeration unit, air-cooledport 50 mm Ø in the right sidepanelsafety cut-out against hightemperatures(protection of test specimen)Ethernet and USB interfacepotential-free contact forspecimen disconnectioncalibration of 2 temperaturevaluesOptions . . .observation window with testspace illuminationsoftware S!MPATI*temperature measurementon specimencompressed air drieradditional access portsrack with shelfadditional shelveslaboratory trolley for WT 64,120 and 240Technical data . . .Series WT WT 64/75 WT 120/70 WT 240/70 WT 450/70Test space volume litres approx. 64 120 240 450Dimensions of housing Height mm approx. 400 400 800 800Width mm approx. 500 500 500 800Depth mm approx. 330 600 600 700Overall dimensions Height mm approx. 1,200 1,200 1,615 1,950Width mm approx. 890 890 890 1,190Depth mm approx. 940 1,210 1,210 1,310Design table-top units free-standing unitsTemperature range °C –75 … +180 –70 … +180 –70 … +180 –70 … +180Temperature constancy, in time K ± 0.2 … ± 0.7Temperature homogenity, in space K ± 0.5 … ± 2.0Cooling-down rate 2) K/min approx. 2.5 2.0 1.5 0.7Heating-up rate 2) K/min approx. 2.8 2.0 1.4 0.7Power supplyConnected loadCondenser1/N/PE AC 230 V ±10 %, 50 Hz, 16 A1.5 kWair-cooledWeight kg approx. 180 210 260 310The performance data refer to an ambient temperature of +25 °C, 230 V nominal voltage, without specimen1) Referring to the adjusted setpoint value in the temperature range of a minimum temperature to +150 °C2) according to IEC 600 68-3-5Subject to technical modifications.
