Reliable. For peace of mind. The Peltier cell-based cooling system features excellent temperature variation and fluctuation. It improves the temperature recovery time (for example after opening the door) and the humidity inside the chamber is extremely stable. In the images below, the temperature/humidity diagram with the test points displayed according to the ICH Q1 A (R2) guidelines and the recording of temperature and humidity over time. STEAM HUMIDIFIER KKP climatic chambers with steam humidifier do not emit ultrasound and therefore allow the reproduction of insects (e.g. Drosophila melanogaster). Furthermore, thanks to their wide temperature and humidity range they can be used for testing electronic components, plastics or building materials. ENERGY SAVING Thanks to latest generation technology, the KKP series humidifier heats very quickly, using only the water necessary. LOW WATER CONSUMPTION Water consumption is only 90 ml per day for KKP 240 and 290 ml per day for KKP 750 (at 40°C, 75% RH). Water consumption is so low that the tank will only need to be refilled every two months. Furthermore, thanks to a heater in the waste water tank, no maintenance is required and the climatic chamber can be installed anywhere. PELTIER TECHNOLOGY: SIMPLE AND RELIABLE The Peltier cell refrigeration system is a modern technology used in various refrigeration or heating instruments, thanks to its innate versatility. The strengths of Peltier technology are the scalability of the cooling elements, the possibility of operating anywhere, its reliability and precise power control. Furthermore, the Peltier elements work without moving parts and therefore without vibrations or noise. One of the main advantages compared to traditional compressors is that no flammable or environmentally harmful refrigerants are used and in general, the whole system is much simpler, avoiding breakdowns. To find out more, we recommend the Wikipedia page Thermoelectric cooler. In particular, for incubation, Peltier cells bring several advantages: Zero vibration - Through the use of Peltier cells, the vibrations previously generated by the compressor are eliminated. Minimal fluctuation and variation: excellent fluctuation, variation and short time to reach the set temperature. Lighter design with more space: Peltier cooling system reduces the overall size of the instrument and its weight. Ecological: Peltier technology is simple and does not use substances harmful to the environment. Below are simple operating diagrams of the ILP incubators during cooling and heating. DETAILS AND ACCESSORIES Every detail of your POL-EKO models is designed to make routine work as simple and comfortable as possible. Below, the structure and accessories of the KKP models. 1 - touch control panel 2 - USB port 3 - open door sensor 4 - ø30mm access port for external sensor 5 - room fan 6 - door handle with key lock 7 - shelf 8 - internal glass door 9 - main power socket 10 - fan for electronic compartment 11 - LAN 12 - cooling system based on Peltier modules 13 - humidifier module 14 - drying module 15 - demineralised water tank Together with the climatic chamber you will also receive: OPTIONS POL-EKO allows you to increase the possibilities of your climatic chamber with quality accessories; to better adapt to particular applications or to equip the instrument with safety systems and advanced connections. - Door with panoramic window - Perforated shelf - Reinforced shelf - Stainless steel basins - Stainless steel wire shelf - Internal socket - Water level sensor - IQ OQ PQ calibration and qualification - Backup battery for the display in case of power failure - Clean contact - Non-standard 20/60/100 mm access door - Additional 30 mm access door
