USE AND FUNCTION
TK Series Climatic Cabinets are developed to simulate real environmental condition by
controlling temperature, humidity and lighting cycles. TK Series Climatic Cabinets are used
for different sectors such as electric and electronic industry, automobile industry, automobile
supply industry, chemical industry, plastic industry, textile industry, pharmaceutical industry,
food industry, packaging industry, plant growth, seed germination, incubation and rearing of
insects.
TK Series Climatic Cabinets maintain temperatures from -10°C to 60°C when the lights are
off and from 0°C to 60°C when the lights are on, humidity from 20% to 95% for temperature
range between 10°C and 60°C. It keeps the temperature and humidity stable within the given
tolerances.
The homogeneity of the temperature and humidity is obtained by the help of the circulation
fan that is located at the upper part of the chamber.
The chamber is made of stainless steel. Fluorescent lamps, starters and other electrical parts
are kept outside of the chamber for easy cleaning of the chamber. The outer body including
the door is made of epoxy-polyester powder coated stainless steel to resist high humidity
levels.
Heating is carried out by using heaters that are located at the upper back side of the chamber,
cooling is carried out by the help of the evaporator which refrigerant gas passes through and
the humidifying is carried out by a humidity generator.
The chamber of TK Series Climatic Cabinets is illuminated from one side by the lamps placed
inside the door. Lighting can be programmed depending on the requirement separately and
two different illumination periods can be programmed. When all the lights are on the light
intensity is about 6000 lux %10 for TK 120, 12000 lux %10 for TK 252 and 13000 lux
± ±
%10 for TK 600.
±
Temperature and humidity can be observed on the LC display located on the door.
The humidity is measured by the humidity sensor. The temperature is measured by PT-100
sensor. As the advantage of the system, the recovery time is fast and humidity measurement
sensitivity is %1 Rh and temperature sensitivity is 0.1ºC. The heating is controlled by PID
while cooling is controlled by proportional system.
The control system also contains a comprehensive self-diagnostic system to provide the
information regarding any system malfunction. The self-diagnostic system warns the user in
case of overheating, heater failure, cooling system failure, low water level, full reserve tank.
TK Series Climatic Cabinets are manufactured according to
EN 61010-1, EN 61000-4-2, EN 50419 and EN 55014-1 standards.
This device is in compliance with WEEE Regulation.
