Stop losing time, energy, and yield to outdated solvent recovery methods. The BVV 2540 Nanofiltration Skid delivers industrial-grade ethanol recovery at up to 30 gallons per hour — without heat, without compromise. Engineered for Class 1 Division 1 environments, this skid is built for serious extraction operations that demand throughput, precision, and energy efficiency in a single compact footprint.
Why the BVV 2540 Nanofiltration Skid
Traditional rotary evaporators are slow, labor-intensive, and thermally destructive to sensitive compounds. The BVV 2540 Nanofiltration Skid replaces up to 7× 50L rotary evaporators with a single, automated system — recovering ethanol at scale without applying heat. This means your target cannabinoids, terpenes, and botanical extracts remain intact while you dramatically cut energy costs and labor overhead.
Unlike falling film evaporators that consume significant power and require constant thermal management, the 2540 Skid operates on membrane-based nanofiltration technology driven by a Variable Frequency Drive pump. The result is a system that qualifies for energy-saving rebates, runs continuously with minimal operator intervention, and scales with your production demands — available in 15 GPH and 30 GPH configurations with Solvent Recovery or Purification membrane options.

- Cannabis & Hemp Processors – Ideal for winterized crude processing where preserving cannabinoid and terpene profiles is critical.
- Commercial Extraction Labs Scaling Up – Upgrade from batch-based evaporation to continuous-flow nanofiltration without rebuilding your entire facility.
- Energy-Conscious Operations – Facilities seeking to reduce their carbon footprint and qualify for utility rebates through lower-energy solvent recovery.
Directions for Use
- Position the skid in a C1D1-rated area with adequate ventilation and access to 230V/60Hz/1-phase power (13A).
- Connect 1.5" intake and retentate lines to your feed tank and collection vessel.
- Connect 1/2" permeate and pressure relief lines per the included plumbing diagram.
- Power on the Polyscience chiller and allow the heat exchanger to reach operating temperature before starting the pump.
- Use the VFD panel to set target flow rate; adjust manual pressure controls to achieve desired transmembrane pressure.
- Monitor the dual 0–1000 PSI pressure gauges and C1D1 flowmeter throughout operation.
- The 700 PSI pressure relief valve with diversion line provides automatic overpressure protection.
- Note: This unit is designed for bulk solvent recovery (approximately 90% of total solvent volume). An additional solvent recovery apparatus is recommended to evaporate to dryness.

Frequently Asked Questions
What is the difference between the Solvent Recovery and Purification membrane configurations?
The Solvent Recovery configuration is optimized for separating and recovering ethanol or methanol from your extract stream at maximum throughput. The Purification configuration uses membranes designed to concentrate and refine botanical extracts, removing unwanted compounds for a cleaner end product.
Can this skid replace my falling film evaporator entirely?
The 2540 Skid handles approximately 90% of bulk solvent recovery without heat. For complete evaporation to dryness, a supplemental solvent recovery apparatus is recommended. In most operations, it significantly reduces or eliminates the need for a falling film evaporator.
What solvents are compatible with this system?
The BVV 2540 Nanofiltration Skid is designed for use with ethanol and methanol. Contact BVV before using any other solvents to confirm membrane and seal compatibility.
What power requirements does this skid need?
The unit requires 230V/60Hz/1-phase power at 13A for the VFD enclosure. Ensure your facility has appropriate electrical infrastructure before installation.
How do I maintain the nanofiltration membranes?
Membrane lifespan depends on feed quality, operating pressure, and solvent type. Regular flushing with clean solvent after each run and periodic integrity testing are recommended. Replacement membranes are available through BVV.
Does this unit qualify for energy rebates?
Yes — the dramatically lower energy consumption compared to thermal evaporation methods makes this skid eligible for many utility energy-saving rebate programs. Check with your local utility provider for specific program requirements.
What is the lead time for this product?
The BVV 2540 Nanofiltration Skid carries an 8–12 week lead time from order confirmation. Plan accordingly for facility integration and production scheduling.
