ACV Condensate Collector

Overview

The ACV Condensate Collector is an engineered solution for reliable, passive collection of condensate formed during gas sampling and environmental monitoring processes—particularly in industrial stack emissions, flue gas analysis, and ambient air quality monitoring systems. Unlike active refrigerated chillers or heated sample lines, the ACV operates on a gravity-fed, thermally passive principle: it provides a dedicated, temperature-stabilized low-point trap where water vapor and volatile condensables (e.g., sulfuric acid mist, organic vapors, or hydrolyzable compounds) phase-change and accumulate as liquid. Its design mitigates carryover risk, prevents line blockage, and ensures representative gas-phase sampling upstream by eliminating intermittent droplet entrainment. The unit is constructed from chemically resistant materials—including fluoropolymer-lined stainless steel and PTFE-sealed fittings—to maintain integrity under acidic, humid, or corrosive sampling conditions common in EPA Method 5, ISO 16913, and VDI 2066-compliant applications.

Key Features

• Passive, maintenance-free condensate separation without power or moving parts
• Modular mounting interface compatible with standard 1/4″–3/8″ OD sample tubing and DIN/ISO pneumatic connectors
• Integrated liquid reservoir with calibrated volume markings (250 mL nominal capacity)
• Optional integrated capacitive or float-type level sensor (output: 4–20 mA or digital RS-485 Modbus RTU)
• Compatible with ALA-series audible/visual alarm modules for high-level alerting (IEC 61000-4-2 compliant)
• CE-marked housing with IP65 ingress protection; operating temperature range: −20 °C to +60 °C
• Traceable material certification available per EN 10204 3.1 for GMP/GLP-regulated installations

Sample Compatibility & Compliance

The ACV Condensate Collector is validated for use with corrosive and hygroscopic gas matrices, including but not limited to flue gas (SO₂, NO_x, HCl), biogas (H₂S, siloxanes), landfill emissions, and semiconductor process exhaust. It complies with key international sampling standards governing condensate management: ASTM D6348 (for gaseous pollutant sampling), ISO 12141 (stationary source emission monitoring), and EN 14181 (QAL3 requirements for automated measuring systems). When deployed in regulated environments—such as those subject to EU Industrial Emissions Directive (IED) or US EPA 40 CFR Part 60 Subpart A—the ACV supports data integrity by preventing uncontrolled condensate re-evaporation and ensuring consistent dew point control upstream of analyzers. Optional documentation packages include Factory Acceptance Test (FAT) reports and calibration certificates traceable to NIST or EURAMET standards.

Software & Data Management

While the base ACV unit is hardware-only, its optional level sensor enables integration into centralized environmental monitoring software platforms via standard industrial protocols. When paired with SCADA or EMS systems (e.g., Siemens Desigo CC, Honeywell Experion PKS, or open-source Grafana + MQTT stacks), real-time fill-level telemetry can trigger automated workflows—such as initiating pump purge cycles, logging event timestamps for audit trails, or generating preventive maintenance alerts. All digital outputs support timestamped, signed data logs compliant with FDA 21 CFR Part 11 requirements when implemented with appropriate system validation (e.g., electronic signature enforcement, audit trail activation, and role-based access control). Firmware updates for sensor modules are delivered via secure HTTPS and verified using SHA-256 checksums.

Applications

• Continuous emission monitoring systems (CEMS) for coal-fired, biomass, and waste-to-energy plants
• Pre-analyzer conditioning in Fourier-transform infrared (FTIR) and UV-DOAS gas analyzers
• Calibration gas delivery systems requiring moisture-free reference streams
• Indoor air quality (IAQ) studies involving VOC-laden humidified air streams
• Research-grade atmospheric chemistry sampling where phase separation must preserve speciation integrity (e.g., carbonyl compounds, organic acids)
• Pharmaceutical cleanroom HVAC monitoring per ISO 14644-1 and EU GMP Annex 1

FAQ

Is the ACV Condensate Collector suitable for high-acidity flue gas applications?
Yes. The wetted components are fabricated from 316L stainless steel with PFA or ETFE lining, providing resistance to pH < 1 condensates containing sulfuric, nitric, or hydrochloric acid at temperatures up to 50 °C.

Can the ACV be installed vertically or only horizontally?
It is designed for horizontal installation to maximize residence time and phase separation efficiency. Vertical mounting is not recommended due to reduced droplet coalescence surface area and potential bypass flow paths.

Does the unit require periodic draining or manual intervention?
Draining frequency depends on condensate generation rate. In typical stack applications (≤10 g/m³ moisture), manual emptying is required every 2–7 days. With optional level sensing and external pump actuation, fully autonomous operation is achievable.

Is third-party verification available for compliance claims?
Yes. Independent test reports from TÜV Rheinland and Kiwa are available upon request, covering material compatibility (EN ISO 15203), electromagnetic immunity (EN 61326-1), and mechanical durability (EN 60068-2 series).
