Solvent Vapour Recovery Unit — VR Series
Assess vapour condensation separately from liquid filtration. Select the recovery duty from the solvent, gas stream and operating conditions.
Request a Vapour Recovery AssessmentRecover Condensable Vapour, Not Suspended Coolant Solids
A solvent vapour recovery unit treats a gas stream containing condensable solvent vapour. The VR series uses direct-expansion cooling as the basis of its condensation arrangement. This is a different equipment duty from a coolant centrifuge, which handles suspended solids in a liquid. The two should not be specified or compared using the same flow or performance assumptions.
The first question is whether the actual vapour stream is suitable for the proposed recovery arrangement. Identify the solvent or mixture, inlet conditions, carrier gas and expected operating pattern. A general request to recover VOCs is not enough to establish compatibility, collection rate or the required outlet condition.
This page presents the available VR reference specifications and the information needed for assessment. It does not claim universal solvent compatibility, a fixed recovery percentage, hazardous-area approval or compliance with a particular emission limit. Those points require review against the exact project and documented configuration.

VR Series Reference Data
| 모델 | Airflow | Collection tank | Power |
|---|---|---|---|
| VR-40 | 40 m³/h | 1 L | 0.85 kW |
| VR-80 | 80 m³/h | 2 L | 1.7 kW |
| VR-100 | 100 m³/h | 2 L | 2.4 kW |
Airflow is a gas-volume rating, not a liquid-solvent recovery rate. The collection-tank figure is a storage capacity, not the amount recovered per hour or per batch. Power is an equipment reference and does not establish the refrigeration duty available under every inlet condition. Keep these quantities separate when comparing a process requirement with the table.
The series description includes direct-expansion cooling and automatic adjustment according to load. The exact control response, operating limits and installation requirements should be confirmed in the project documentation. Automatic adjustment does not mean that inspection, condensate handling or maintenance can be omitted.
Understand What Determines Condensation Performance
Condensation depends on the vapour composition and operating conditions, including concentration, pressure and temperature. Cooling a stream may collect part of its condensable content, while an outlet stream still remains. The required result therefore needs an agreed measurement rather than an assumption that all vapour becomes recovered liquid.
The US EPA's condenser monitoring overview identifies outlet gas temperature and outlet VOC concentration as important performance indicators. That general principle does not establish the performance or regulatory status of a particular VR installation; it explains why inlet and outlet conditions belong in the assessment.
Different solvents and mixtures require different evaluations. Moisture, entrained droplets and other contaminants may also affect the arrangement. Provide the known composition and safety information rather than relying only on the commercial name of the cleaning or process fluid.
Characterise the Stream at Its Source
Measure or estimate the gas flow at the proposed connection and state how that value was obtained. Distinguish normal operation from startup, batch peaks and shutdown. A nominal extraction-fan rating elsewhere in the system may not describe the stream entering the recovery unit under the installed resistance.
Provide inlet temperature, pressure information where relevant, solvent concentration if known and the process schedule. If the concentration is unknown, mark it as unknown. Airflow alone cannot support a credible recovered-liquid quantity or savings estimate because the amount of solvent carried by the gas has not been established.
Identify the capture arrangement and what happens to the outlet stream. A recovery unit should not be used as a reason to reduce necessary workplace ventilation without an appropriate engineering and safety review. The complete capture, treatment and discharge system needs to be considered, not just the machine between two ducts.
Confirm Compatibility and Safety before Selection
Send the solvent safety data sheet and identify any mixed or changing stream components. Wetted materials, seals, electrical equipment and the intended location must be assessed for the actual service. Do not assume that suitability for one solvent establishes suitability for another with a similar application name.
State the site's hazardous-area classification and any required approvals, if applicable. This page makes no ATEX or explosion-proof claim. Required certification and safe integration must be confirmed for the exact supplied configuration; absence of a stated restriction in a short catalogue is not evidence of approval.
The responsible project team should also review collection, transfer and storage of condensate. A small tank can still contain material that needs controlled handling. Applicable environmental, occupational and fire-safety requirements should be established by competent personnel for the installation jurisdiction.
Treat Recovered Liquid as a Separate Quality Decision
Condensed liquid is not automatically ready to return to production. Its composition may differ from the original process fluid, especially when several vapours or moisture are present. Define the quality checks needed before reuse and whether a further treatment or segregation step is required.
Identify how collection will be monitored and how the container will be emptied. The reference tank capacity should be considered alongside the expected collection rate and operating schedule, once those have been established. Avoid choosing a model by tank size alone or assuming that a larger tank proves a higher recovery efficiency.

If reuse is not appropriate, define the permitted waste route. The engineering proposal should account for the liquid collected and the gas leaving the equipment. Moving solvent from one stream to another does not remove the need to manage either stream responsibly.
Build the Proposal around a Verified Duty
Start with a feasibility review, followed by the measurements or trial needed to define the application. Agree the inlet envelope, required outlet result and measurement method. Then compare the appropriate model and installation arrangement against that duty. This sequence avoids choosing a unit from airflow alone and discovering later that the solvent or load was different.
Keep economic estimates conditional until operating data and a quotation are available. A credible comparison needs the actual solvent loading, recoverable amount, acceptable reuse route, energy use and handling costs. This page does not publish a payback period because those inputs are project-specific.
The VR series remains a separate equipment line from Vimfun's liquid centrifuges. For a vapour recovery enquiry, provide gas-stream information rather than coolant sump volume or suspended-solids capacity. We will use that information to identify the next technical review, not make an automatic model recommendation from a single number.
