Experience the latest technology of stirring with MAC Ceramic Coated Magnetic Stirrer. Equipped with LED display for set and actual temperature. Available with external PT-100 sensor (optional) for precise control of temperature with on accuracy of 1C. Separate safety circuits and warning indications, for over temperature even in the switch OFF condition.

Construction of double walled, with rigid framework and heavily insulated with glass wool, fresh air inlet and suitable exhaust will be provided. The interior will be finished with heat resistant aluminium and the outer is finished with attractive colour paint

Heating is accomplished by the aid of strip heaters made out of imported BDH Nichrome wire provided on the sides of the inner chamber to obtain maximum temperature.

In order to obtain uniform temperature, specially designed air circulation fans are fitted on the side of the unit. The design is such the unit will suck the hot air to pass over the trays and throw it one the sides where they will be reheated and recriculated to continue the cycle. A part of the air is to come out to throw out the moisture fan motor suitable for different size of driers are give below:-

Temperature: 50 to 250 Degree Celsius

Inn SS 304, outer M.S. powder coated surface. Shaking speed 40 to 120 rpm with ss top cover.
