DCP-5 / DCP-17 / DCP-20 Low-Temperature Cooling Circulator Series
High-performance low-temperature cooling circulators designed for rotary evaporators, jacketed reactors, spectrometers, and distillation systems. Features PID temperature control from -20°C to +40°C, eco-friendly R404a refrigerant, and powerful circulation pumps.
-20°C to +40°C Temperature Range | Up to 1500W Cooling Power | PID Temperature Stability (±0.3°C) | Eco-Friendly R404a
Key Features
- Broad Low-Temperature Range: Regulates bath temperature from -20°C to +40°C with high refrigeration efficiency.
- PID Temperature Precision: Intelligent PID controller with PT100 sensor maintains stability at ±0.3°C with 0.1°C display resolution.
- Powerful Circulation Pump: Delivers flow rates up to 22 L/min and pressures up to 1.5 bar for uniform closed-loop cooling.
- Eco-Friendly Refrigerant: Uses non-toxic, non-polluting R404a refrigerant with excellent heat absorption performance.
- Convenient Liquid Handling: Top liquid filling port, rear drain port, clear fluid sight glass, and overflow protection.
- Low Noise & Energy Efficient: Proportional refrigeration control minimizes power draw and reduces operational noise.
- Easy Maintenance: Removable front grille allows quick cleaning of the condenser air filter.
Applications
Provides consistent chilled fluid loops for rotary evaporators, jacketed reaction vessels, condensers, distillation columns, atomic absorption spectrophotometers (AAS), ICP systems, semiconductor testing, and bioreactor temperature control.
