Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and volatile organics degrade rapidly if wastewater samples are allowed to sit at ambient room temperature. Desalytics refrigerated samplers feature precision compressor cooling that holds collected samples strictly at 4°C, preserving biological and chemical integrity in full accordance with national environmental standards.
Refrigerated Systems Range
- Precision Temperature Regulation: Forced-air refrigeration circuit holding sample bottles consistently between 2°C and 4°C regardless of external heat.
- Discrete & Composite Bottle Flexibility: Easily configured for a single 10L, 20L composite carboy or multi-bottle discrete carousels (24x 1L bottles) for 24-hour profiling.
- Non-Contact Liquid Detectors: Ultrasonic liquid sensors ensure exact, repeatable sample aliquot volumes regardless of changes in sample head pressure.
The Desalytics Operational Advantage
- Regulatory Audit Assurance: Continuous temperature logging proves sample integrity to auditing authorities during compliance reviews.
- Direct Flow Meter Tracing: Accepts 4-20mA and dry contact pulses to perform true flow-proportional composite sampling.
- Turnkey Commissioning & Service: Desalytics field technicians provide on-site installation, flow pacing configuration, and annual refrigeration servicing.
