Information VCS7027-10

This equipment is used in case fast temperature variations shall be simulated. This equipment is also well suited for experiments where a lot of power is dissipated inside the test volume.

This thermal stress chamber is ideal for performing thermal stress tests on all sorts of materials because of the possibility of rapid temperature variations (HAST tests) and this in a large volume of 270 L. A typical application is the acceleration of ageing processes, for example, adhesive bonding, solder joints, composite materials, etc.


Test space volume:
270 liters (W x D x H) = 580mm x 620mm x 750mm

Up to 8 grids used in the test room with a maximum load of 30kg per grid and a maximum total load of 80kg.

Maximum load on the floor of the test room: 60kg.

Door with window which allows the samples to observe during a test without opening the chamber. This can be useful to a screen that is part of the test piece to read.

A flange (right side): Ø125mm
A flange (left side): Ø50mm


Temperature Range: -70 ° C to +180 ° C
Temperature change according to IEC60068-3-5:
heating: 10.0 ° K / min
cooling: 14.5 ° K / min

B - Relative Humidity

Heat Compensation: 400W in the range of 25 ° C to +95 ° C
at a relative humidity up to 90%
Sensor: psychrometric moisture probe

Power: AC 400V 3/N/PE + / -10% 50Hz AC 230V OR 3/PE + / -10% 50Hz
Nominal power: about 14kW
Provide safety fuse: 32A
Data Interface: RS-232 and Ethernet connection for remote operation and monitoring through the SIMPATI software. The full operation of the unit and the registration of all data can be done through this interface.

An air-cooled condenser is also part of the equipment. This is used for the second stage in the cooling circuit. The condenser is connected to the thermal chamber by two flexible connections.

Intuitive and easy control of the chamber. Simple programming of individual test PROGRAMS € ™ s.
Programmable dehumidifier to prevent condensation on the test well to avoid

Protection of test well: Safe use of the room by means of two independent safety circuits: a thermal cut through the control software and a fully independent hardware temperature limiter.

Good test interfacing: 4 digital outputs for the test well on or off via potential free contacts (Maximum 24 VDC 0.5 A). 4 digital inputs for reading status lines coming from the test well (24 VDC 30mA max). A free temperature sensor (PT100) can be used at any place within the test area, or well on the test itself, to measure. All these signals / values ​​may include temperature and humidity via the Ethernet interface of the test case are recorded.

Elimination of test items: Potential-free contact material especially for heat-emitting Test (Maximum 24 VDC 0.5 A)
