This document serves as the user's manual for the Nüve TK 120, TK 252, and TK 600 series of Climatic Test Cabinets, manufactured by NÜVE SANAYİ MALZEMELERİ İMALAT VE TİCARET A.Ş. These devices are designed to simulate real environmental conditions by precisely controlling temperature, humidity, and lighting cycles.
The TK Series Climatic Cabinets are versatile instruments used across various industries, including electric and electronic, automobile, chemical, plastic, textile, pharmaceutical, food, and packaging. They are also employed in plant growth, seed germination, incubation, and insect rearing.
These cabinets are capable of maintaining temperatures within a range of -10°C to 60°C when the lights are off, and 0°C to 60°C when the lights are on. Humidity can be controlled from 20% to 95% within a temperature range of 10°C to 60°C, ensuring stable conditions within specified tolerances. Temperature and humidity homogeneity inside the chamber are achieved through a circulation fan located at the upper part.
The chamber itself is constructed from stainless steel, with fluorescent lamps, starters, and other electrical components positioned outside for ease of cleaning. The outer body, including the door, is made of epoxy-polyester powder-coated stainless steel, providing resistance to high humidity levels. Heating is facilitated by heaters located at the upper back side of the chamber, while cooling is managed by an evaporator through which refrigerant gas passes. Humidification is performed by a humidity generator.
Illumination within the chamber is provided by lamps placed inside the door, allowing for programmable lighting cycles. Two distinct illumination periods can be programmed to meet specific requirements. The light intensity varies by model: approximately 6000 lux ±10% for the TK 120, 12000 lux ±10% for the TK 252, and 13000 lux ±10% for the TK 600, when all lights are on.
The control system includes a comprehensive self-diagnostic feature that provides information on system malfunctions. This system alerts the user to issues such as overheating, heater failure, cooling system failure, low water level, or a full reserve tank.
Operating the TK Series Climatic Cabinets involves a straightforward process, starting with switching on the unit and navigating the display and control panel. The main control panel, located on the door, allows for observation of temperature and humidity. An auxiliary control panel on the side houses the On-Off switch, RS 232 port (optional for PC communication), and a printer port for dot matrix printers. It is crucial to connect the printer before starting any program if printing is desired.
Programming the device involves setting language, date, and time, followed by defining specific test parameters. Users can select program names, set the number of cycle repetitions, and determine how the program should behave in case of a power failure (either stopping or continuing). The time counting condition can also be chosen, either starting immediately or after the set parameters are reached. Programs can be saved to memory for future use.
Humidity usage during a program can be enabled or disabled. The system allows for adjustment of temperature and humidity alarm periods, with temperature alarms adjustable between 2°C and 10°C, and humidity alarms between 5% and 20% RH. The specific temperature and humidity values for each step of a program can be set, with up to nine steps available for multi-stage tests. The duration of each step can be set in hours and minutes, or to a "HOLD" position for continuous operation until manually stopped.
Illumination settings can be accessed via a dedicated control key. Users can program two distinct daily periods for lighting, defining start and stop times. The illumination can also be set to activate when the door is opened. It's important to note that if illumination is set to "START," the date and time cannot be changed.
The device incorporates safety warnings, particularly emphasizing not to open the door when temperature and humidity levels inside the chamber are high, to prevent burns. The self-diagnostic system provides clear error messages for issues like overheating, cooling failure, communication errors, power failure, broken sensors, insufficient water, and a full water tank, guiding the user to appropriate actions or to contact authorized service.
Regular maintenance is essential for the optimal performance and longevity of the TK Series Climatic Cabinets.
Monthly Maintenance: The chamber should be cleaned monthly. This involves unplugging the equipment and allowing it to reach room temperature. After removing the shelves, the chamber surface should be wiped down to remove any residue from operations. A mild detergent is recommended for stubborn dust and dirt. Users must be cautious about the effects of chemicals used for cleaning. A critical warning states: "DO NOT SPRAY WATER OR OTHER LIQUIDS DIRECTLY ON ANY PART OF EQUIPMENT. OTHERWISE THIS MAY CAUSE SERIOUSLY ELECTRICAL DAMAGE."
Every Three Months: The cooling performance can be affected by dust accumulation on the condenser. Therefore, the condenser should be cleaned quarterly using a vacuum cleaner. The frequency of this cleaning may vary depending on the operating hours of the equipment and the dust level in the working environment. To access the condenser, the right and left cover sheets must be opened with a key. The warning against spraying water or liquids directly on the equipment is reiterated for this task due to the risk of serious damage.
Every Year: While the electrical and mechanical components are designed for reliability and do not typically require periodic maintenance, an annual check by authorized technicians is advisable. This check should include temperature and humidity calibrations, assessment of the cooling system's performance, and verification of the alarm system's reliability.
Disposal Management: The manual emphasizes adherence to local regulations for disposal of the device and its components. The user is responsible for arranging proper disposal. Electronic accessories (excluding batteries and power packs) should be disposed of according to electronic waste regulations. Batteries, power packs, and similar power sources must be dismounted and disposed of in accordance with applicable local regulations.
The device is designed for indoor use only, with an optimal room temperature range of 5°C to 30°C. Maximum performance is achieved at 22°C and 80% humidity. The maximum altitude for operation is 2000 m. Users must ensure that the mains supply matches the required power ratings and always plug the instrument into correctly grounded sockets. The waste water outlet height should not exceed 15 cm. A circuit breaker-fitted supply is recommended for protection against indirect contact in case of an insulation fault.
