Product Overview
Industrial thermal applications require continuous hot-water generation and precise temperature control. High-temperature heat pumps meet these demands by operating the refrigeration circuit at optimized temperature lifts, transferring thermal energy through dedicated water-side heat exchangers.
The current industrial platform features models ranging from approximately 75.5 kW to 172.5 kW in rated heating capacity, utilizing 380 V, 50/60 Hz power supplies, EVI DC inverter compressors, and robust water-side heat exchangers.
Actual thermal output and efficiency vary according to source temperature, water flow rates, entering water temperatures, and target leaving water temperatures. Proper sizing requires evaluation against project-specific design points.

Key Technical Features
EVI DC Inverter Compressor
Equipped with Enhanced Vapor Injection (EVI) DC inverter technology, the system modulates compressor speed to respond dynamically to changing thermal loads. EVI technology maintains heating capacity and operational stability at lower ambient temperatures and higher temperature lifts.
Robust Heating Capacity Range
Current industrial configurations span from 75.5 kW to 172.5 kW rated heating capacity per single outdoor unit. Larger thermal requirements can be met by arranging multiple units in modular cascade configurations.
Engineered Water-Side Heat Exchangers
The hydraulic circuit is designed to handle specific flow rates and pressure drops. Current models feature water flow rates from 13 to 29.7 m3/h with connection sizes ranging from DN50 to DN80.
Hybrid Solar System Architecture
Designed to integrate directly with photovoltaic (PV) arrays or solar thermal systems, allowing facilities to offset electrical power consumption while maintaining consistent thermal output.
Intelligent Control Architecture
The integrated control system manages compressor staging, electronic expansion valves, temperature setpoints, and protective functions, supporting connection to Building Management Systems (BMS).
Typical Industrial Applications
The equipment serves facilities seeking to replace or supplement conventional electric resistance heaters, steam boilers, or fossil-fuel heating systems:
Industrial Process Water: Supplying heated water for manufacturing, washing, rinsing, and surface treatment processes.
Factory Centralized Hot Water: Delivering high-volume hot water for industrial workshops, manufacturing plants, and employee facilities.
Food and Agricultural Processing: Providing controlled thermal energy for food preparation, cleaning, and processing operations.
Commercial Laundries: Supporting high-demand, continuous hot-water consumption in commercial laundry facilities.
Large-Scale Facilities: Centralized hot-water generation for hospitals, hotels, resorts, and institutional dormitories.
Greenhouse Climate Control: Integrating with hydronic floor-heating or perimeter pipe systems for agricultural greenhouses.
Aquatic Facility Heating: Maintaining large swimming pools and water parks under continuous operating schedules.
Renewable Energy Integration: Combining with photovoltaic or solar thermal systems to minimize grid electricity consumption.
System Working Principle
The heat pump operates via a closed-loop vapor-compression refrigeration cycle:
Heat Absorption: The evaporator extracts low-grade thermal energy from ambient air or alternative source loops.
Temperature Elevation: The compressor increases refrigerant pressure and temperature to create the necessary thermal lift.
Heat Transfer: The condenser-side heat exchanger transfers thermal energy directly to the circulating water circuit.
Thermal Delivery: Heated water is supplied to process loops, buffer tanks, or storage vessels.
Capacity Modulation: Variable-speed operation adjusts compressor output dynamically to match real-time thermal loads.
System Integration & Hydraulic Configuration
Industrial installations require proper hydraulic design to ensure long-term reliability. Typical system layouts incorporate:
- High-temperature heat pump modules
- Hydraulic buffer tanks and hot-water storage vessels
- Primary and secondary circulation pumps
- Plate heat exchangers for fluid separation
- Expansion vessels and safety relief valves
- Water filtration and scale-prevention units
- Flow meters and temperature sensors
- Central control panels with BMS communication gateways
For large thermal loads, multiple heat pump units can be installed in a modular cascade arrangement, providing redundancy, staged capacity control, and simplified maintenance routines.
FAQ
Q: What is a high-temperature industrial heat pump?
A: An industrial heat pump extracts thermal energy from low-grade sources (such as ambient air or waste heat) and raises it via a closed-loop refrigeration cycle to deliver high-temperature water suitable for industrial processes and commercial heating networks.
Q: What information is required to select the correct model?
A: Accurate selection requires the heating load (kW), entering and leaving water temperatures, required water flow rate, local ambient design temperatures, operating hours, and available electrical supply.
Q: Can the heat pump integrate with solar energy systems?
A: Yes. The system can operate alongside photovoltaic (PV) arrays or solar thermal installations to form a hybrid renewable heating configuration, reducing grid electricity consumption.
Q: Does a higher outlet water temperature affect system efficiency?
A: Yes. Raising the leaving water temperature increases the compressor temperature lift, which reduces the effective heating capacity and COP. Units must be selected based on your exact design temperatures rather than standard catalog ratings.
Q: Can multiple units be combined for large heating loads?
A: Yes. Multiple units can be configured in modular cascade layouts to meet large thermal capacity requirements while providing staging flexibility and operational redundancy.
