Cooling laboratory incubator KB 720

hot airthermoelectricfor scientific research

Product description
The KB series offers two laboratory cooling incubator variants for microbiology: KB 720 with inverter compressor cooling and KB ECO 720 with thermo‑electric Peltier regulation. Both provide controlled incubation from 0 °C to +70 °C, stainless‑steel interiors, programmable setpoints and internal data logging. The KB 720 adds hot‑air disinfection and higher load capacity; the KB ECO 720 provides very low noise and optimized Peltier energy performance.

Benefits

• Precise: tight temperature control and spatial uniformity for reproducible cultures
• Reliable: robust stainless‑steel chamber and proven cooling/regulation technologies (compressor or Peltier)
• Hygienic: hot‑air disinfection (KB 720) and door heating to avoid condensation
• Programmable: second setpoint, weekend operation and unit self‑test for status analysis
• Energy‑efficient: modern inverter compressor or optimized Peltier modules reduce energy consumption
