Product Description

Our firm is specialized in manufacturing and exporting superior quality Rotary Film Evaporator that is equipped with Digital RPM indicator & VFD based speed control, Digital Process time indication and Digital Temperature indicator & Controller. The performance of rota-evaporator totally depends on various parameters like temperature differential between bath and contents of flask, RPM, flask capacity and working pressure. An indicative comparison of boil-up of CCI4 rates for 20L, 50L, and 100L is given in adjacent figure. The offered evaporator is manufactured utilizing premium grade components and latest technology in adherence with the international standards. Our offered Rotary Film Evaporator is available in different technical specifications at nominal prices.

Features:

Universal corrosion resistance with only borosilicate glass and PTFE as contact parts.
Auto controlled, variable rotational speed and variable bath temperature with digital display enhances operational versatility and can be used for wide range of duties.
Can be operated under full vacuum or at atmospheric pressure
The unit has continuous feeding facility & total reflux arrangement
Ideally suited for heat sensitive material due to uniform heating at low temperature with enhanced heat transfer area.
Maintenance free working- operational reliability
Fully Automatic (PLC based) can be supplied on request.

Construction and Working:

Rotary Film Evaporator is essentially a thin film evaporator. The rotating flask continuously covers a large surface area with a thin film which is ideal for rapid heat transfer. Fortuitously, the thin film also ensures uniform heat distribution with out local heating. The facility to work the unit under full vacuum further facilitates evaporation at as low temperature as possible. That is to say, both boiling point and residence time are significantly reduced. These features combined, renders rotary film evaporator to be ideally suited for evaporation of heat sensitive material. It is equally successful for evaporation of suspension in crystallization processes, drying of powder/granules etc.
