Boe-Therm TEMP 300 High-Temperature Thermal Oil Temperature Control Unit

Overview

The Boe-Therm TEMP 300 is a high-precision, industrial-grade thermal oil temperature control unit engineered for demanding process environments requiring stable and repeatable thermal management up to 300°C. Designed and manufactured in Denmark under stringent quality protocols, the system employs a closed-loop circulation architecture using synthetic high-temperature heat transfer fluid (YD-400 series) to deliver uniform thermal energy to molds, reactors, or test fixtures. Its core operating principle relies on PID-regulated electric resistance heating combined with forced convection via high-pressure, high-flow circulation pumps (P3/P4 variants), enabling tight temperature stability (±1°C) across extended operational cycles. The unit integrates multi-layer composite insulation to minimize parasitic heat loss—verified at <3% under nominal load—while maintaining operator safety through IP65-rated heating chamber enclosures and anti-scald front-panel design. Unlike conventional oil heaters, the TEMP 300 operates under controlled micro-positive pressure (<5 bar), eliminating vapor lock risks and ensuring consistent fluid dynamics during transient thermal ramping.

Key Features

• High-temperature capability: Continuous operation up to 300°C with precision PID control (±1°C setpoint accuracy)
• Modular heating power selection: Six configurable options from 6 kW to 36 kW, supporting scalable integration into pilot-scale and full-production lines
• Thermal efficiency optimization: Multi-layer vacuum-insulated jacketing and low-emissivity internal shielding reduce standby and operational heat loss to <3%
• Robust circulation architecture: P3 and P4 high-pressure centrifugal pumps deliver up to 66 L/min at 3.4–4.4 bar, compatible with high-backpressure tooling and long-loop piping
• Intelligent thermal management: Programmable cooling profiles, real-time vacuum-run interlock, automatic oil volume compensation, and rapid mold drainage function support automated production sequences
• Industrial-grade acoustic design: Enclosed motor-pump assembly and vibration-damped mounting achieve ≤58 dB(A) at 1 m distance, meeting ISO 7779 noise emission standards for laboratory and cleanroom-adjacent deployment
• Comprehensive safety framework: Dual-channel temperature monitoring, overpressure relief, dry-run detection, and CE-compliant emergency stop circuitry per EN 60204-1:2018 and EN 60519-1:2015

Sample Compatibility & Compliance

The TEMP 300 is compatible with standard synthetic heat transfer oils rated for continuous service above 300°C (e.g., YD-400 series), and supports both internal reservoir (18–65 L) and external tank configurations depending on heating power rating. Its 1/2″ BSP hot-side process port and 3/8″ BSP coolant inlet enable direct integration with injection molding machines, extrusion dies, calorimetry test chambers, and chemical synthesis reactors. The system conforms to CE marking requirements under the Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. It is certified to ISO 9001:2015 for design, manufacturing, and distribution processes. Optional ATEX certification (II 2G Ex db IIB T4 Gb) is available for Zone 1 hazardous area deployment. All electrical interfaces—including Profibus-DP, Profinet, Ethernet/IP, and DeviceNet—are implemented per IEC 61784-1 and IEC 61158 specifications to ensure deterministic real-time communication in synchronized automation environments.

Software & Data Management

The TEMP 300 features an embedded controller with dual-mode HMI (touchscreen + physical keypad), supporting local parameter configuration, trend logging, and alarm history review. All operational data—including temperature setpoints, actual loop values, pump status, oil level, and runtime counters—are timestamped and stored internally for ≥30 days. Standard 4–20 mA analog outputs and 20 mA serial RS-485 interfaces allow seamless integration with SCADA, MES, and PLC-based control systems. Digital fieldbus protocols (Profibus-DP, Profinet, Ethernet/IP, DeviceNet) provide full device diagnostics, parameter mirroring, and remote firmware updates compliant with IEC 61131-3 programming environments. Audit trail functionality meets GLP/GMP documentation requirements, including user login tracking, configuration change logs, and electronic signature-capable event archiving aligned with FDA 21 CFR Part 11 principles where enabled via external supervisory software.

• Material testing laboratories: Thermal cycling of aerospace alloys, ceramic sintering pre-heating, and high-temp tensile fixture conditioning
• Pharmaceutical equipment validation: Dry heat sterilization cycle support, autoclave jacket temperature mapping, and lyophilizer shelf pre-conditioning
• Automotive R&D: Battery thermal management system (BTMS) component testing, EV power electronics thermal soak simulation, and engine coolant loop emulation

FAQ

What is the maximum allowable temperature deviation during steady-state operation?
The system maintains ±1°C setpoint accuracy under full-load conditions at 300°C, verified per DIN EN 60584-2 calibration traceability using dual independent PT100 sensors.
Can the TEMP 300 operate with water-glycol mixtures instead of synthetic oil?
No. The unit is specifically engineered for synthetic high-temperature heat transfer fluids (e.g., YD-400). Water-based media are incompatible due to vapor pressure limitations and thermal degradation risks above 150°C.
Is remote firmware update supported over Ethernet/IP?
Yes. Firmware upgrades and configuration backups can be executed remotely via Ethernet/IP using vendor-supplied configuration tools compliant with ODVA guidelines.
Does the system include built-in validation documentation for GxP environments?
The TEMP 300 ships with IQ/OQ documentation templates and factory calibration certificates. Full 21 CFR Part 11 compliance requires integration with validated third-party data acquisition software.
What is the expected service interval for the circulation pump and heat exchanger?
Under normal operating conditions (clean oil, ≤300°C, ≤5,000 hr/year), scheduled maintenance is recommended every 12 months or 5,000 operating hours—whichever occurs first—per the manufacturer’s maintenance manual (Rev. 4.2, 2023).
