VELP FTC 120 Constant-Temperature BOD Incubator

Overview

The VELP FTC 120 Constant-Temperature BOD Incubator is a purpose-engineered environmental chamber designed exclusively for biochemical oxygen demand (BOD) analysis in compliance with standard methods including ISO 5815-1:2019, ASTM D5210-19, and EPA Method 405.1. It maintains a strictly regulated incubation temperature of 20 °C—per the internationally mandated condition for five-day BOD₅ testing—using a high-stability electronic temperature control system coupled with an A+-rated refrigeration module. Unlike general-purpose incubators, the FTC 120 integrates dedicated internal power outlets rated for continuous low-voltage operation, enabling direct electrical connection and synchronized powering of up to three 6-position or two 10-position BOD analyzer systems. Its forced-air circulation architecture ensures rapid thermal equilibration and minimizes vertical/horizontal gradients across the entire 109 L working volume, delivering reproducible incubation conditions essential for regulatory-grade wastewater and environmental water quality testing.

Key Features

• Fixed-point 20 °C incubation mode optimized for BOD₅ standard compliance
• ±0.5 °C temperature uniformity across full chamber volume, verified per ISO 15378 and validated during factory calibration
• Dedicated dual internal power sockets (230 V, 50–60 Hz), each independently fused and rated for continuous 120 W load
• Two-digit LED display with 1 °C resolution and real-time temperature feedback loop
• A+-class energy-efficient compressor-based cooling system with low-GWP refrigerant (R600a)
• Robust stainless-steel interior chamber and insulated double-wall construction (60 mm polyurethane foam)
• Compact footprint (540 × 912 × 550 mm) suitable for laboratory benchtop or dedicated BOD workflow zones

Sample Compatibility & Compliance

The FTC 120 accommodates standardized BOD sample configurations without modification: it supports simultaneous operation of up to 18 BOD bottles (via three 6-position systems) or 20 bottles (via two 10-position systems), all maintained at precisely 20 °C for the full 120-hour incubation period. Chamber geometry and airflow design prevent condensation accumulation on bottle surfaces or electrode housings—critical for DO probe stability and sensor drift mitigation. The unit conforms to IEC 61010-1:2010 safety requirements for laboratory equipment and carries CE marking under the EU Machinery Directive. Its fixed-temperature architecture eliminates user-setpoint variability, reducing human error risk in GLP and ISO/IEC 17025-accredited laboratories. Routine performance verification follows VELP’s documented IQ/OQ protocols aligned with FDA 21 CFR Part 11 data integrity expectations for environmental monitoring instrumentation.

Software & Data Management

The FTC 120 operates as a standalone hardware platform with no embedded software or network interface—consistent with its role as a regulated physical incubation environment rather than a data-generating instrument. Temperature monitoring is analog-electronic, with no internal logging or USB/RS232 output. For audit-trail compliance, users integrate external calibrated temperature data loggers (e.g., compliant with NIST-traceable standards) placed within the chamber at defined locations (center, top shelf, bottom shelf). VELP provides a downloadable PDF validation guide (Ref. DOC-FTC120-VG-EN) outlining recommended placement, frequency, and acceptance criteria for periodic operational qualification per ISO/IEC 17025 Clause 6.4.2.

Applications

• Routine BOD₅ determination in municipal and industrial wastewater treatment plants
• Environmental monitoring of surface water, groundwater, and effluent discharge points
• Validation and routine use in ISO/IEC 17025-accredited environmental testing laboratories
• Teaching laboratories requiring stable, low-maintenance incubation for undergraduate water quality modules
• Supporting parallel multi-analyzer workflows where synchronization and spatial uniformity are critical

FAQ

Is the FTC 120 programmable for other temperatures?
No. It is a fixed-temperature incubator engineered solely for 20 °C BOD₅ testing and does not support adjustable setpoints.
Can the internal power outlets supply both BOD meters and dissolved oxygen probes?
Yes—each outlet delivers stable 230 V AC power compatible with standard BOD analyzer electronics and associated electrochemical sensors.
Does the unit include temperature mapping documentation?
VELP supplies a factory-verified temperature uniformity report (per ISO 15378 Annex C) with each unit; full mapping per USP or EU GMP Annex 1 requires user-conducted qualification.
What maintenance is required for long-term reliability?
Annual inspection of condenser coil cleanliness, door gasket integrity, and calibration verification using traceable reference thermometers is recommended.
Is the FTC 120 compatible with VELP’s FOC series incubators for integrated lab workflows?
While functionally complementary, the FTC 120 is electrically and mechanically independent; no shared control bus or software integration exists between FTC and FOC platforms.
