Cooling laboratory incubator KB 470

forced convectionfor scientific researchfor microbiology

Product description KB 470 cooling incubators are designed for precise incubation of microorganisms even under full load. The units include a hot‑air disinfection routine, easy programming for secondary setpoints and an energy‑efficient inverter cooling system that reduces consumption by up to 40% versus the previous model.

Benefits

• Assured: consistent, highly precise incubation conditions through power reserves
• Reliable: long‑term, failsafe operation with proven compressor technology and stainless‑steel interior
• Smart: hot‑air disinfection routine and simple programming of a second set temperature
• Economical: up to 40% lower energy consumption thanks to modern inverter cooling

Important characteristics

• Temperature range: 0 °C to +70 °C
• APT.line™ preheating chamber technology
• Inverter cooling unit with climate‑neutral R‑600a refrigerant
• Door heating to prevent condensation
• HIT sandwich housing technology
• Interior fully stainless steel; inner doors of metal‑oxide coated safety glass
• Two stainless‑steel racks (standard); access port 80 mm x 45 mm with silicone plug
• Floor‑standing with sturdy twin casters and front brakes
• Internal data logger; measured values exportable in open format via USB
• Class 3.3 independent temperature safety device (DIN 12880) with visual and acoustic alarms
• Unit self‑test and data interfaces: Ethernet, USB
