Cooled Incubators LEEC A-PDF Split DEMO Models PFC2C, P3C & P33C Standard Features Controls q PID Microprocessor with digital display. q Digital overtemperature safety cutout. Construction q Stainless steel chamber with adjustable shelves. q Efficient polyurethane foam insulation. q Two 12mm access ports. These models are of a rugged design and are fitted with microprocessor controls. Heating and Cooling q Unique pulsed heating and cooling is very energy- efficient. q Quiet hermetically sealed compressor, with air cooled condenser. q Low wattage heaters are bonded to the outer wall of the chamber to eliminate ‘hot-spots’. Construction All models are made from rust resistant steel finished in tough white stove enamel paint. Inner chambers are made from stainless steel and have adjustable shelves. The circulation fan gently forces air around the chamber via a full-width rear duct. Two access ports Specification are provided so that cables can run into the chamber for shakers, stirrers PFC2C P3C P33C Models or temperature monitoring probes. The low wattage heaters are bonded to the 0°C to +60°C Temperature* Range outer wall of the chamber and surTypically ±0.2°C Control rounded by polyurethane insulation to Typically ±0.5°C Variation help achieve optimum temperature CFC-free Refrigerant stability. Construction Chamber Exterior Castors Access Port Insulation Stainless steel White painted steel Optional Standard, 2x12mm CFC-free Chamber Capacity (litres) Sheves Supplied Safety q Digital overtemperature safety cutout with visual alarm. q Chamber is internally sparkfree. q Insulation is CFC free. Chart recorder. Audible alarm. Auto defrost. Dual temperature cycling. Microprocessor Controls The temperature controller accurately controls both the heating and cooling functions. The unique LEEC cooling system controls refrigerant flow to the evaporator, thereby eliminating the possibility of unwanted overcooling. Heating is pulsed only as required. Pulsing is a very energy-efficient method of achieving stable temperature control and eliminates the need for autodefrosting except at the lowest of operating temperatures. Note LEEC also manufacture a range of Separate Self-contained Refrigeration Units to use with LEEC Precision Incubators. These are particularly useful in crystalography work as they eliminate vibration. Contact our sales office for details. Dual Temperature Cycling This optional facility allows the chamber temperature to cycle automatically between two preset values. *Temperature specification for Model PFC2C at 20°C ambient. 13
