Operation with Color Touch Panel
The color touch panel, suitable for graphics with a resolution of 800 x 480 Pixel (VGA), is part
of the standard equipment. It allows a convenient input of fixed values and program operation
with graphic display of set points and actual values, the operating time and number of remaining
cycles etc. Furthermore, the touch panel has the following special features:
Background-lit display
Menu-guidance
Easy programming of individual test programs
Safe storing of individual programs, which can be activated at any time
Operation state displayed by means of light diodes
Languages (switchable)
Standardized display of all parameters (temperature, humidity etc.)
Technical Details
Construction
The climate test chambers are supplied ready for connection. Compact design means a minimum of space is required. Three test chambers with a volume from 100 to 1000 l are available. All chambers are designed to be free-standing in one location.
The machine section incorporating the refrigeration unit, the water storage tank and the water pump is located below the test chamber. The swing-out switch cabinet is located on the rear of the cabinet. The operating elements and the main switch are located on the right side of the cabinet.
Exterior Housing
The exterior housing of the unit is made from lightweight corrosion-resistant, self-supporting, galvanized sheet-steel.
The environmental-friendly insulation between test chamber and exterior housing guarantees best insulation values and thus lowest possible operating costs.
Test Chamber
The test chamber consists of a stainless-steel container and is welded vapor-tight. The test chamber is easy to clean thanks to special welding, smooth surfaces, rounded edges and shelf supports. The rear test chamber wall incorporates an air duct with built-in humidifier tub (C models), built-in heat exchanger, electric heaters and a recirculating air fan. Air guidance via baffle plates in the test chamber floor and ceiling produces optimum ambient air and temperature distribution.
Test Chamber Door
The test chamber is completely sealed by a door that is hinged on the left. It is provided with an observation window (not for ECO version). The door opens fully for easy access and is equipped with high quality insulation. An optimum seal is guaranteed by special profile seals and a self-tightening locking mechanism which is operable with one hand.
Access Ports
All chambers have two access ports (approx. 50mm diameter) made of low thermal conductivity material. The ports are in the left and right side walls and can be used for measuring and control wires, other supply connections or accessories.
If not required, these ports are closed with rubber plugs supplied as standard.
Temperature and Humidity Conditioning
The large axial fan with exterior drive motor draws the air out of the space. This recirculating air then passes a fin-type heat exchanger, which cools the air, if necessary. The special design of the refrigerating system avoids unintended condensation precipitation at the heat exchanger during climatic operation and guarantees highest temperature and humidity constancies in time. An electrical heater, installed in front of the heat exchanger in air direction, is heating-up the recirculating air.
An innovative humidification system allows a high relative humidity even with a heat load (C models).
Protection System against Condensation
The protection system consists of a dehumidifying evaporator which prevents condensation forming on the specimens as they heat-up after tests at low temperatures.
The protection system's operating range is -40 to +60 °C.
The protection system against condensation is activated by a digital switch channel. It is possible to switch on the protection system manually or to integrate it into a program.
Permanently Memorized Overheating Safety Thermostat
A steady state overheating safety thermostat is installed that automatically switches off the heater if the test chamber's maximum temperature range is exceeded.
Power Supply
Each functional circuit is equipped with its own safety device, which, in the event of trouble, turns off the affected circuit or the entire cabinet. The nature of the trouble is visually displayed.
Wiring and electrics are governed by the latest technology and strictly conform to safety regulations for electrical installations and materials, as well as to relevant VDE regulations.
The test chamber are standard-wise equipped with a lockable main switch according to VDE.
General Statements
In the constant effort to improve our product, we reserve the right to make construction or design changes without prior notice or obligation.
Please note that for installation of the climate test cabinet (for components which jut out, such
as: hinges, locks, etc.) the clearance requirements indicated in the technical data must be observed.
The performance data indicated were determined with empty test space and refer to an appliance without additional ports or devices, which represent a thermal load with an ambient temperature of max. +25 °C and with water-cooled refrigeration units (option) to a water temperature of approx. +28 °C.
The admissible ambient temperature for operation of the cabinet is between +10 °C and +35 °C (+50 °F and +95 °F).
Performance data cannot be guaranteed in ambient conditions other than those stated.
Accuracy rates are proven in the test space center, in steady state, without specimens, without radiation and without additional equipment in the test space. The cooling down rate stated refers to the temperature range without controlled humidity.
Noise measurements and sound level data are effected as per DIN 45 635, part 1, accuracy class 2.
In case of outgassing or pollution caused by the specimen we recommend regular maintenance of the measuring system. Please keep in mind that outgassing of specimens and connection lines might cause corrosion of components. Corrosive gasses might escape among others from chip boards, cardboard boxes and bandaging materials. If outgassing is to be expected, we recommend an optional ventilation of the test space with a purge air volume. If outgassing or pollution is expected, we also recommend a regular maintenance of the measuring system。
Measures to be taken regarding a necessary combination with other units have to be approved by the local supervising authorities. The relevant costs are not included in our quotation.
Please note that the sealing material and cable insulation used in our test units and systems contains silicone. If this is a problem for you, please contact us.
The EMC test and the data on the noise emission are in accordance with EN 50 081-1 and EN61 000-6-2.
