Ningbo Scientz DC-0510 Low-Temperature Circulating Bath (Heating & Cooling)

Overview

The Ningbo Scientz DC-0510 Low-Temperature Circulating Bath is an engineered thermal management system designed for precise, stable, and bidirectional temperature control of liquid media in laboratory and industrial R&D environments. Operating on a closed-loop refrigeration cycle with integrated electric heating, the unit delivers accurate thermal regulation across a broad operational range—from cryogenic conditions at −40 °C to elevated temperatures up to +100 °C. Its core architecture employs a high-efficiency, hermetically sealed Danfoss (Secop) compressor, environmentally compliant R134a refrigerant, and PID-controlled microprocessor logic to maintain thermal uniformity within ±0.1 °C under steady-state conditions. Unlike passive water baths, the DC-0510 actively circulates conditioned fluid both internally (for bath homogeneity) and externally (to serve auxiliary equipment), making it functionally equivalent to a compact, self-contained chiller-heater source. This dual-mode capability supports applications requiring dynamic thermal profiling, sustained isothermal operation, or remote load conditioning—without reliance on external chillers or heating mantles.

Key Features

• High-stability temperature control: Achieves ±0.1 °C stability over full operating range via adaptive PID algorithm and platinum resistance temperature sensor (PT100) feedback
• Dual circulation mode: Switchable internal recirculation (for bath uniformity) and external circulation (for external device cooling/heating), with adjustable flow rate (0–20 L/min)
• 7-inch angled capacitive touchscreen interface: Provides real-time display of setpoint, actual temperature, elapsed time, alarm status, and pump speed; supports multi-language UI and intuitive parameter navigation
• Intelligent power recovery: Retains all user-defined settings—including temperature setpoint, timer, and startup mode—after power interruption; configurable auto-restart or standby-on-power-up behavior
• Acoustically optimized refrigeration: Secop compressor with vibration-damping mount and insulated condenser housing reduces operational noise to ≤58 dB(A) at 1 m
• Comprehensive safety architecture: Overtemperature cut-off, compressor overheat/overload protection, low-level fluid alarm, dry-run prevention, and automatic shutdown on sensor failure

Sample Compatibility & Compliance

The DC-0510 accommodates aqueous solutions, silicone oils, ethylene glycol/water mixtures, and other non-corrosive heat-transfer fluids compatible with stainless-steel (SUS304) bath chamber and circulation tubing. Its design conforms to IEC 61010-1:2010 for electrical safety in laboratory equipment and meets CE marking requirements for EMC (EN 61326-1) and low-voltage directives. While not certified for use in GMP production environments per se, its programmable timer, parameter logging, and repeatable thermal profiles support GLP-compliant experimental documentation when integrated into validated lab workflows. The unit is routinely deployed in ASTM D5275 (viscosity standards calibration), ISO 17025-accredited testing labs, and university research facilities where traceable thermal control is required for method validation.

Software & Data Management

The DC-0510 operates autonomously via embedded firmware with no PC dependency. All operational parameters—including target temperature, ramp rate, hold time, pump speed, and alarm thresholds—are stored in non-volatile memory. Optional RS485 (Modbus RTU) or USB-to-serial interface enables integration with LabVIEW, MATLAB, or SCADA systems for remote monitoring and scheduled protocol execution. Audit-ready data export (CSV format) is supported via USB flash drive, capturing timestamped temperature logs at user-selectable intervals (1 s to 60 min). Though not FDA 21 CFR Part 11 compliant out-of-the-box, the system’s deterministic behavior, immutable parameter retention, and hardware-based safety interlocks facilitate qualification for regulated QC/QA applications when paired with procedural controls.

Applications

• Condenser cooling for rotary evaporators (e.g., maintaining 5 °C coolant supply during solvent removal)
• Thermal regulation of non-contact ultrasonic disruptors (e.g., controlling sample temperature during cell lysis)
• Exothermic/endothermic reaction control in jacketed glass reactors (±0.1 °C precision critical for kinetic studies)
• Calibration of temperature-sensitive instrumentation (thermocouples, RTDs, IR sensors) across extended ranges
• Stabilization of optical benches, laser diodes, and semiconductor test fixtures requiring low-drift thermal sinks
• Biological incubation support—e.g., maintaining constant temperature for enzyme assays, protein crystallization trays, or microbial culture media

FAQ

What is the maximum external flow pressure this unit can deliver?
The built-in centrifugal circulation pump provides up to 0.3 MPa (3 bar) head pressure at zero flow, with rated flow of 15 L/min at 0.1 MPa—sufficient to drive coolant through typical lab-scale heat exchangers and jacketed vessels.
Can the DC-0510 be used with flammable solvents like acetone or ethanol?
No. The bath chamber and circulation system are rated only for non-flammable, non-aggressive heat-transfer fluids. Flammable liquids pose fire and compatibility risks and void warranty and safety certifications.
Is remote programming supported via Ethernet or Wi-Fi?
Standard configuration includes RS485 Modbus RTU and USB interfaces only. Ethernet or Wi-Fi connectivity requires third-party gateway integration and is not natively supported.
How often does the refrigerant require servicing or replenishment?
Under normal operation and proper maintenance (clean condenser coils, stable ambient 15,000 operating hours).
Does the unit meet UL or CSA safety certification for North American laboratories?
The DC-0510 carries CE marking and complies with IEC 61010-1. UL/CSA certification is not currently held; users requiring such certification should consult Scientz’s OEM partnership program for region-specific compliance options.
