Description

The UHTHP Series is a heavy-duty industrial heat pump designed to recover waste heat (from wastewater, flue gas, or industrial cooling loops) and upgrade it into continuous process water or low-pressure steam ranging from 90°C to 120°C. Engineered as a direct low-carbon alternative to fossil fuel boilers, the system integrates into chemical, food and beverage, pulp, and district heating facilities for Scope 1 emission reduction.

Key Features

Dual-Stage Compression
Tandem semi-hermetic screw compressors arranged in a cascade cycle maintain volumetric efficiency under high thermal lifts.

Low-GWP Refrigerants
Optimized for R1336mzz(Z) and R1233zd(E) working fluids, fully compliant with regional environmental and F-Gas regulations.

Structural Durability
Thick-gauge carbon steel chassis (Q355B / ASTM A572) finished with epoxy-polyurethane coatings for 24/7 indoor or outdoor plant deployment.

Thermal Lubrication Management
Active oil cooling and high-viscosity synthetic lubricants prevent thermal breakdown at 120°C discharge thresholds.

Technology & Performance

Thermodynamic Optimization
Multi-stage compression divides specific work per stage, curbing discharge spikes and protecting compressor service life.

Part-Load Modulation
Electronic expansion valves (EEV) and variable speed drives (VSD) adjust refrigerant mass flow to maintain high COP across 30% to 100% operational loads.

Anti-Freeze Defense
Automated cycle reversal and fluid bypass protect low-temperature heat sources from freezing without interrupting baseline thermal delivery.

Industrial Applications

Food & Beverage
Pasteurization loops, Clean-in-Place (CIP) hot water supply (85°C to 95°C), and liquid concentration.

Chemical & Pharmaceutical
Reactor jacket heating and high-temperature solvent stripping circuits.

Pulp, Paper & Textile
Boiler feed-water pre-heating and drying make-up air conditioning.

District Heating
Substation boosting to lift municipal return temperatures (50°C) to network setpoints (90°C to 110°C).

OEM & ODM Customization

Hydraulics
Tailored nozzle sizes, flange standards (ANSI, DIN, JIS), and multi-circuit header matching.

Metallurgy
Titanium plate exchangers for corrosive industrial streams; cupronickel piping for saline environments.

Control Logic
Custom PLC programming, IP65 enclosure upgrades, and redundant sensor architecture aligned with plant Safety Instrumented Systems (SIS).

Quality Control & Testing

Pressure Vessel Integrity
All shell-and-tube exchangers and refrigerant piping undergo 100% Non-Destructive Testing (NDT), including radiographic (RT) and ultrasonic (UT) inspection per PED/ASME rules.

Full-Load Factory Testing (FAT)
Units undergo automated dynamometer run-tests prior to dispatch, measuring thermal stability, capacity, power draw, and vibration profiles under simulated site conditions.

Circuit Sealing
Helium mass spectrometer pressure testing guarantees zero-leakage performance before refrigerant charging.

Packaging & Logistics

Skid Design
Heavy steel skid featuring integrated forklift channels and certified overhead lifting lugs.

Dehydration
Refrigerant circuits evacuated, dehydrated, and sealed under a positive dry nitrogen holding charge (0.2 to 0.3 bar). Control cabinets protected by desiccant packs and anti-condensation heaters.

Transport Protection
ISPM 15 heat-treated wood crating or shrink-wrapped open-skid transit equipped with shock-impact indicators.

FAQ

Q: How does COP respond when the heat source drops below 40°C?

A: COP declines proportionally with increased temperature lift (Delta T) in accordance with Carnot efficiency limits. For volatile sources, a secondary thermal buffer tank or staging is recommended.

Q: Can this system generate direct steam?

A: The standard series produces pressurized hot water up to 120°C. Low-pressure flash steam generation (120°C to 135°C saturated) requires specialized high-lift configurations subject to engineering review.

Q: What is the required maintenance schedule?

A: Filter checks and sensor calibrations are advised every 2,000 operating hours. Full compressor oil analysis and valve checks are scheduled annually (every 8,000 hours).
