KNF C 900: versatile for all laboratories

Temperature control units from KNF are used in a wide variety of laboratories. Many of our customers rely on the KNF C 900, which impresses with its strong performance and first-class durability. As a result, it is ideal for use in microbiological, histological, clinical and environmental laboratories.

Working with the C 900 optimizes, for example, work in sample preparation, reactor temperature control, material stress tests or temperature simulations to be performed.

Important product features at a glance

The instrument can be operated intuitively after installation and makes everyday work much easier. This model operates in the temperature range from -10 °C to + 40 °C and thus covers a sufficiently wide temperature range. It can be easily combined with KNF's RC 900, SC 920 G, RC 600 or N920 G, VC 900 and RC 600.

The unit also features a filling volume of 1.7 – 2.6 liters and also has a fill level indicator to make filling particularly easy.

In addition, the splash-proof membrane keypad ensures safe and clean operation.

Features and design

The compact and simple design ensures that the model fits perfectly into a modern laboratory. The cleverly positioned ventilation slots on the front of the device allow several to be placed directly next to each other without causing heat to build up. The LED display on the front shows the temperature at a glance.

Special protections

The model offers additional protective devices to make the operation as safe as possible. The over-temperature protection device is set at 85 °C and ensures shutdown in the event of overheating. The low-level protection device, in turn, switches off the compressor if there is too little temperature control liquid in the unit.

Technical data

Since the technical data of a product should always be taken into account when making a purchase decision, we offer some information on the most relevant points here.

The C 900 arrives with the dimensions 235 mm x 520 mm x 400 mm and is thus very compactly designed. This means it can be placed and used well even in tight spaces. With its 27 kg weight, the recirculating cooler from KNF can be easily moved even by a single person.

At a voltage of 230 V and a current consumption of 3 amps, the cooler consumes approximately 690 watts per hour. Of course, this varies depending on the ambient temperature and other external influences.

The device from KNF Neuberger GmbH complies with European standards such as Directive 2014/30/EU (Electromagnetic Compatibility), Directive 2006/42/EC(Machinery) and Directive

2011/65/EU (RoHS2). It also complies with EN 61010-1, EN 61010-2-010, EN 61326-1, EN 378-1/2/3/4 and EN 5058.
