Climate chamber KBF 470

humiditytemperaturestability

Product description
The KBF 470 is a constant climate chamber designed for reliable ICH stability testing in pharmaceutical and laboratory environments. It supports long‑term, accelerated and stress tests with programmable profiles, documented data export and flexible water supply options for varied installation sites. Optional light modules convert the unit for ICH photostability testing or plant growth applications.

Benefits

• Suitable for critical ICH stability tests thanks to high climate homogeneity even under full load
• Reliable long‑term operation using proven compressor technology and stainless‑steel interior
• Ergonomic operation with touchscreen program controller and signal triangle status display
• Up to 40% lower energy consumption than the previous model with modern inverter refrigeration

Important characteristics

• Temperature range: 0 °C to +70 °C
• Humidity range: 10% to 80% RH (with humidity control 10...70 °C)
• APT.line™ preheating chamber technology
• Energy‑efficient inverter cooling unit with R‑600a refrigerant
• Door heating to prevent condensation
• Adjustable fan speed and robust HIT sandwich housing
• Humidity control using a capacitive humidity sensor and responsive steam humidification
• Stainless‑steel inner chamber and inner doors of metal‑oxide coated safety glass
• Signal triangle with illuminated status display and ergonomic, adjustable operating terminal
• Internal data logger; measured values exportable in open format via USB; data interfaces: Ethernet, USB
• Class 3.3 independent temperature safety device (DIN 12880) with visual and acoustic alarms
