All models are made from rust resistant steel finished in tough white polyester powder coat paint with anti-microbial properties. Inner chambers are made from stainless steel and have adjustable perforated stainless steel shelves. All models have inner glass doors. The fan (two in the P33C) circulates the hot and cold air around the chamber via a full-width air duct. Two 12mm access ports are provided so that cables can run into the chamber for shakers, stirrers or temperature monitoring probes. The low wattage heaters are bonded to the outer wall of the chamber and surrounded by expanding polyurethane foam insulation to help achieve optimum temperature stability.
The digital 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 by the controller only when required. Pulsing is a very energy-efficient method of achieving stable temperature control and eliminates the need for auto defrost, except when operating at the lowest chamber operating temperatures.
A digital over and under temperature alarm / cut out system provides essential protection for your products inside the chamber. Visual warning lights and audible alarms give clear indications when the chamber temperature is out of limits. The cut out will disconnect the heating or cooling system if an over or under temperature situation occurs.
Digital Dual Temperature Cycling
This option allows the chamber temperature to automatically ramp up and down (or cycle) between two pre-programmed temperatures. Timers are available in 24 hour or 7 day type.
