Our Pilot-Scale Rising Film Evaporator (RFE) is specifically designed for concentration of heat-sensitive, low-viscosity liquids under controlled conditions. This equipment is ideal for process development, R&D trials, and small-scale production in industries such as pharmaceuticals, chemicals, food & beverage, and biotechnology.

Key Features:

• Vertical tubular evaporator design ensures efficient heat transfer

• Rising film mechanism allows thin film formation for gentle evaporation

• Steam or hot water jacketed heat exchanger for uniform heating

• Vapor-liquid separator at the top for efficient phase separation

• Feed and product tanks with integrated flow and level controls

• Skid-mounted compact structure for easy installation and mobility

• Customizable configurations for multi-effect or solvent recovery processes

• Automation-ready with temperature, pressure, and flow control instrumentation

Applications:

• Solvent recovery

• Concentration of herbal extracts and APIs

• Wastewater minimization

• Evaporation of thermally sensitive solutions

The pilot-scale RFE is engineered for scalability, making it a valuable tool for bridging the gap between lab and full-scale industrial operations. We also offer trial services, process optimization support, and custom fabrication based on client-specific requirements.

An agitated Thin Film Evaporator (ATFE) or Wiped Film Evaporator (WFE) is a rotary evaporator used for efficient and controlled evaporation, concentration, or distillation of liquids, particularly heat-sensitive, viscous, or fouling-prone materials. The rotor has blades that keep a close clearance from the shell. 
The liquid is applied to the heated wall in a thin coating via a feed distributor at the entry site. As the film pours down, the high-speed rotor vigorously agitates and distributes it further. An integrally attached entrainment separator cleans the produced vapours as they flow counter-current.
Features:1. Thin Film Formation: This maximises the surface area for heat transfer and ensures uniform heating2. Agitation: The agitator continuously scrapes the surface, reducing the risk of fouling, scaling, or overheating, ensuring turbulent flow, even for highly viscous liquids, and enhancing efficiency3. Short Residence Time: The liquid spends very little time in the heated zone, minimising thermal degradation4. Product hold-up is low

An Agitated Thin Film Evaporator (ATFE), commonly referred to as a Wiped Film Evaporator (WFE), is a highly efficient rotary evaporation system designed for the controlled evaporation, concentration, or distillation of liquids. It is especially suitable for heat-sensitive, viscous, or fouling-prone materials.

How It Works:

• The core structure is a jacketed shell precisely machined for optimal heat transfer.
  
  

• The high-speed rotor with blades operates with minimal clearance from the shell.
  
  

• The liquid feed enters through a feed distributor and spreads into a thin film along the heated wall.
  
  

• The rotor continuously agitates the liquid film, promoting even distribution and maximizing contact with the heated surface.
  
  

• An integrally attached entrainment separator cleans the vapors, which flow counter-current to the liquid, improving separation efficiency and vapor quality.
  
  

• The process operates in a once-through mode without recirculation, reducing product degradation and minimizing hold-up.
  
  

Key Features:

1. Thin Film Formation:
   
   

   • Maximizes surface area for heat transfer, ensuring uniform heating.
     
     

2. Intense Agitation:
   
   

   • Prevents fouling, scaling, and local overheating.
     
     

   • Maintains turbulent flow even for highly viscous liquids.
     
     

   • Enhances heat transfer efficiency.
     
     

3. Short Residence Time:
   
   

   • The liquid spends only a few seconds in the heated zone, minimizing thermal degradation.
     
     

4. Low Product Hold-Up:
   
   

   • Reduces material loss and improves process control.
     
     

Applications of ATFE / WFE:

1. Pharmaceutical Industry:
   
   

   • Vacuum distillation of bulk drugs, intermediates, and fine chemicals.
     
     

2. Chemical Industry:
   
   

   • Distillation of glycols, used lubricating oils, fatty acids, and their derivatives.
     
     

   • Processing of rubber chemicals, amines, and esters.
     
     

3. Solvent Recovery:
   
   

   • Recovery of contaminated solvents and products from residues.
     
     

Manufacturing Capabilities:

• Capacity range: 0.1 sq.m to 30 sq.m surface area.
  
  

• Operating temperature: 30°C to 300°C.
  
  

• Operating pressure: From full vacuum to 2 bar (g).
  
  

• Construction materials (MOC): SS304, SS316, Hastelloy for chemical compatibility.
