WTS-3/WK-3

The WTS-3/WKS-3 test system is based on our tried and true modules, the WT and WK SERIES, now offer increased power for heating, cooling and circulating air. These chambers have volumes ranging from 190 to 1540 liters, and are capable of meeting virtually all requirements of contemporary ESS testing.
  • The external housing is made of corrosion-resistant, galvanized steel sheets and solvent-free powder coated
  • The stainless steel test space is welded to be vapor-tight. Its environmentally friendly insulation guarantees the best possible insulation values providing the lowest possible operating costs
  • Even in the standard version of the equipment all sizes are equipped with two standard stainless steel ports (approx. Ø 50 and 125 mm). They can be used for inserting measurement and control cables, or other supply connections and additional equipment
  • Test specimen protection with separate sensor according to EN 60159-2
  • Safety alarm is issued visually as well as acoustically
  • The door latch ensures an optimum closing pressure while ensuring protection against excess pressure at the same time
  • The large observation window is available as an option allowing an optimum view of the test space and it is equipped with multiple glazing and heated in order to prevent the formation of condensate
  • A potential-free contract is available on the test cabinet
  • Every functional electrical circuit is equipped with its own safety facility, which shuts down the functional circuit affected or the entire test cabinet in case of a malfunction
  • The electrical system complies with the approved state of the art in the field, the safety regulation “Electrical Systems and Facilities” (BGV A3) as well as with the relevant VDE regulations.
  • All test cabinets fulfill the EMC, low-voltage, machinery directive. The hermetic refrigeration circuits operate with environmentally friendly refrigerants (CFC-free)
  • A quality inspection of every test unit is conducted before delivery. They are designed ready for plug-in and are ready for immediate use. There is no need for on-site assembly
  • Digital measuring and control system Simpac
  • 8’’ TFT-color touch screen display
  • Control-pad for displaying of temperature values, lighting, start / stop, etc. on the front panel of the device
  • Ethernet and USB interface
  • Water-cooled refrigeration unit
  • Stainless steel ports approx. Ø 50 mm and 125 mm in the left and right side panel
  • Safety cut-out against high and low temperatures (protection of test specimen as per EN 60519-2 (1993) adjustable, with separate sensor
  • Insertion rack (stainless steel)
  • Adjustable, vibration absorbing feet
  • 4 digital outputs (24 V-DC)
  • 4 digital inputs (24 V-DC)
  • Potential-free contact for specimen disconnection
  • 2 temperature values are calibrated (+23 °C and +80 °C)
  • Integrated limit value monitoring system for humidity
  • Psychrometric humidity measurement with automatically wetted, self-cleaning sensor
  • Large, easily accessible water tank
  • Automatic feed of additional water without interrupting chamber operation
  • Water shortage alarm
  • Display of the humidity values on the Control-pad
  • Humidity bath purging for cleaning the humidifier water
  • 2 climate values are calibrated (23 °C/50 % r.h. and 95 °C/50 % r.h.)
