DESCRIPTION
FORCED AIR CIRCULATION INCUBATORS FOR THE MODERN BIOMEDICAL AND SCIENTIFIC LABORATORY WITH COMPLETE PID CONTROL
KW offers one of the widest selections in microbiological incubators and thermostatic chambers for biomedical applications, for scientific research and for industry. These are meant for conservation of biological material at controlled temperatures and are indispensable every time a constant ambient temperature must be created for the growth of microorganisms.
Therefore they are used in all hospital laboratories, laboratories for scientific research, agriculture, veterinary medicine, chemicals and in controls for the pharmaceutical, cosmetic and food industry.
KW interprets the needs of the various users, with this reliable and technically advanced line, supported by a competitive know-how and by accurate choices of building materials.
W-WR-LAB incubators are the result of technological innovation, quality in manufacturing and the continuous attention towards the client, all in KW tradition, matured in over 0 years in business.
All models are designed and built according to the ISO 900:000 International Quality System and created in accordance with Mark European safety standards and UNI-EN-600 for laboratory equipment.
KW releases a calibration certificate at +7°C in the centre of the chamber, or others more complex (on specific request).
The WR-LAB series refrigerator groups are built using HFC refrigerants (CFC and HCFC free) for the protection of the environment.
The microprocessor control with exclusive PID action and the DIN 880 class overtemperature regulator ensures a precise and uniform incubation temperature in conditions of maximum operating security.
A wide range of models, capacities and accessories allow the user to choose the ideal solution.
STRUCTURE AND SYSTEM:
External structure and door in sheet steel prepainted or plastic-coated in zinc; insulation in natural mineral fibres; internal chamber and shelves in AISI 0 stainless steel; the shelves can be positioned as desired through mobile supports on racks; these are placed on the internal walls.
All models are equipped with a transparent internal door (in plexiglass or in tempered glass), fitted with a sealing gasket. This allows observation of the samples, without alteration of the internal temperature. The door has a magnetic gasket in PVC.
W-LAB incubators are easy to clean and decontaminate. The heating is obtained with special low thermal density tubular elements (finned), for maximum temperature stability; these are placed in an area separate from the internal chamber, in order to create a very uniform temperature control (with the internal chamber walls) in the working volume. The temperature control flow is driven by a high efficiency helical fan; the speed – in the working volume - is close to the laminarity, and in any case can be regulated with a variable speed drive of the fan itself. Each incubator is equipped with a vent aerator, with adjustable opening.
THERMOREGULATION AND CONTROLS INCLUDE:
• lighted general ON/OFF switch
• digital electronic μP controller, with LED display, with Set value and Process indication RTD Pt 00 Ω probe and PID regulation (proportional, integral, derivative) for maximum stability of T parameter; use of SSR static relays (zero crossing). Regulation parameters optimizable by keyboard, to minimize heating times and avoid temperatures dangerously exceeding the set temperature
• optional adjustable overtemperature controller, in conformity with DIN 880 with separate sensor (protection class.) and with on-panel visual alarm indication and heating exclusion, in case of failure; for maximum security.

• Additional RTD Pt 00 Ohm probe, complete with -0 mA converter, mounted on DIN rails, for connection to external recording system
• BIO-AS-KW, digital electronic device for general surveillance, Vdc self-powered, inclusive of all the alarms (T min/max, etc.), including power failure alarm, with automatic test of battery status and constant status indicator (internal self-diagnostic); complete with contacts for remote alarm setup
• V//60 power supply, on request
An I.Q. (Installation Qualification) and O.Q. (Operational Qualification) can be carried out on this series of equipment; for an evaluation of the costs of these activities, consult the KW commercial office.
KW is also available for ISO calibration certification services for SIT sample comparisons.
