Industrial High Temperature Heat Pump

Delivery Range: Continuous thermal output up to 120°C for washing, pasteurization, drying, and distillation.

Low-GWP Refrigerants: Utilizes eco-friendly hydrofluoroolefins (HFO) or natural fluids, ensuring zero ODP and strict environmental compliance.

Dual-Stage Compression: Tandem or two-stage screw architecture maintains volumetric efficiency and stable pressure ratios under wide temperature lifts.

Corrosion-Resistant Coil: Epoxy-coated copper-fin evaporators coupled with intelligent dynamic defrost control for harsh industrial environments.

Modular Scalability: Supports multi-unit parallel integration via Modbus RTU/TCP protocols, scaling capacity from 100 kW to multi-megawatt systems.

Thermodynamic Optimization
Operating on subcritical/transcritical vapor compression cycles, the system integrates electronic expansion valves (EEV) and shell-and-tube heat exchangers. Pinch points are restricted below 2°C to minimize exergy losses and maximize heat transfer coefficients.
 

Compressor Engineering
Heavy-duty screw blocks feature mechanical internal volume ratio ($V_i$) adjustment, preventing over-expansion and under-expansion losses across wide lifts (e.g., evaporating at 20°C, condensing at 110°C).
 

Lubrication Architecture
To sustain continuous 110°C+ operation, the system incorporates an active oil-cooling loop, a centrifugal oil separator (>99.5% efficiency), and high-viscosity synthetic POE lubricants. 

Food & Beverage: CIP sanitization loops (85°C–90°C) and boiler feedwater preheating.

Textile & Dyeing: Wastewater heat recovery feeding continuous dyeing vats and stenter frame exhaust condensers.

Chemical & Pharmaceutical: Reaction vessel temperature control, solvent pre-heating, and low-pressure steam generation (up to 0.2 MPa).

District Heating: Decentralized industrial waste heat harvesting for municipal networks.

Hydraulics: Customized flange standards (ANSI, DIN, JIS) and material upgrades (Stainless Steel 304/316L or Titanium).

Electrical: UL/CSA or IEC/CE compliant control cabinets matching regional grids (400V, 480V, 600V).

Control Integration: Tailored PLC logic (Siemens S7-1200/1500 or Schneider) for plant SCADA/DCS interface.

Enclosures: Weatherproof IP55 outdoor housing with acoustic insulation limiting noise below 68 dB(A) at 1 meter.

Pressure Vessel Testing: All heat exchangers hydrostatically tested at 1.5 times maximum working pressure per ASME/PED standards.
Leak Verification: Helium mass spectrometer testing ensures annual refrigerant leakage rates below 0.1%.
Full-Load Run Testing: 4-hour hot-gas functional validation on a calorimeter test rig, recording thermodynamic performance, vibration, and power draw.
Traceability: Positive Material Identification (PMI) and mill test certificates (MTC) provided for pressure-bearing components. 

Corrosion Control: Circuits dehydrated and sealed with a 0.05 MPa nitrogen holding charge; electrical compartments vacuum-sealed with desiccants.

Structural Rigging: Bolted to heavy structural steel skids featuring certified fork-pockets and crane-lifting points.

Export Compliance: Secured in ISPM 15 heat-treated wooden crates wrapped in anti-UV moisture barrier film.
