Closed-Loop Liquid Circulation System
Hermetic Design with Expansion Vessel
Expansion vessel is thermally isolated from the main circulation loop (non-participating in thermal transfer).
Mechanical connection only; vessel media temperature always maintained below 60°C, regardless of loop temperature (-45°C to 250°C).
Zero Contamination Operation
No moisture absorption at low temperatures.
No oil mist generation at high temperatures.
Broad thermal fluid compatibility: Suitable for diverse heat transfer oils.
Solenoid-Free Architecture
Eliminates reliance on electromagnetic valves—enhances long-term reliability.
1.Wide Temperature Range:-45°C to +250°C (Heating & Cooling Integrated)
Rapid Cooling Capability: Instantaneous transition from -45°C → 250°C
2.Advanced Control & Display:
7-inch Color TFT Touchscreen,Real-time display of set temperature, actual temperature, and overtemperature alarm thresholds
User-Friendly Interface: Intuitive operation with graphical trends
3.High Efficiency & Safety
Sealed Circulation System:
No oil mist at high temperatures
No moisture absorption at low temperatures
Extends heat transfer fluid lifespan
High-Pressure Pump Design: Supports long-distance fluid delivery
4.Reliable Refrigeration Unit
Emerson Copeland™ Scroll Compressor
Stable performance | High durability
5.Comprehensive Safety Protections
Self-Diagnostic System
Multi-Layer Safeguards:
Refrigerant overpressure cutoff
Overload relay & thermal protection
Compressor auto-shutdown on faults
6.Unified Thermal Fluid Control
Single heat transfer fluid for entire temperature range
Eliminates cross-contamination risks
