The Cooling/Heating Humidity System can control the humidity of the air inside the incubation chamber up to 95% rH without having trouble due to condensation inside the connection tube between the humidifying unit and the incubation room. Our innovative very flexible controllerless heatable tube allows this major technical improvement. The system consists of a humidification chamber with a temperature-controlled base plate, a screwed-on water tank and a heatable tube. A vibration damper is part of the system as an accessory.
