Lesca Tech provides custom-designed FRP (Fiberglass Reinforced Plastic) and PP-FRP (Polypropylene-FRP) reactors specifically engineered for the chemical, pharmaceutical, and fertilizer industries. Our reactors are designed to withstand aggressive chemical reactions, varying temperatures, and mechanical stresses that would cause traditional metallic reactors to corrode or fail.
Technical reactor fabrication
We focus on material compatibility and structural integrity to ensure safe and efficient chemical processing.
Chemical Compatibility Analysis
Our engineers select the optimal resin system (Vinyl Ester, Bisphenol, or Isophthalic) and liner material (PP, PVDF, or CPVC) based on the specific acids, solvents, and operating temperatures of your process.
Structural Filament Winding
For high-capacity reactors, we utilize precision filament winding technology to provide superior hoop and axial strength. This ensures the reactor can handle full-vacuum or positive pressure conditions safely.
"The PP-FRP reactors from Lesca Tech have handled our highly acidic process for over 3 years without a single sign of liner degradation. The agitator support bridge they designed is incredibly stable."
Why choose our chemical reactors
We offer a lightweight, corrosion-proof alternative to Stainless Steel and exotic alloy reactors (Hastelloy, Monel).
Universal Chemical Resistance
Our dual-laminate reactors (PP-FRP / PVDF-FRP) combine the extreme chemical inertness of thermoplastics with the structural strength of fiberglass.
- Resistant to H2SO4, HCl, and NaOH
- No internal coating or lining needed
- Maintenance-free exterior
Integrated Agitator Systems
We provide reactors complete with robust MS-FRP coated agitator bridges and custom FRP impellers (Pitch blade, Paddle, or Anchor types).
- Heavy-duty bridge supports
- Zero-leakage shaft seals
- Dynamic balancing of impellers
FRP Reactor FAQs.
We can manufacture standard vertical reactors with capacities ranging from 500 Liters up to 50,000 Liters (50 KL). For larger on-site requirements, we can provide modular assembly solutions.
PP-FRP uses a Polypropylene liner for the chemical-facing surface, which offers much higher resistance to strong acids and localized hot spots compared to plain resin-rich FRP liners.
Yes, we can provide reactors with external Limpit Coils (half-pipe) or Jackets made of SS or FRP for efficient heat transfer during chemical reactions.
We design our reactors to support various agitator types including high-speed dispersers, anchor mixers, and turbine impellers. The top dish is reinforced to withstand the torque and dynamic loads from the motor and gearbox.
