Product Overview
Industrial heat pump water heaters are engineered for centralized hot water and industrial water-heating applications where conventional electric or gas heating systems result in high operating expenditures.
The system utilizes an enhanced vapor injection (EVI) DC inverter compressor and a robust refrigeration cycle to absorb ambient or solar-assisted thermal energy, transferring it directly into the water circulation loop. Photovoltaic (PV) solar power can be integrated directly into the system to minimize grid electricity dependence.
The current industrial platform covers rated heating capacities ranging from 75.5 kW to 172.5 kW, offering multiple model configurations tailored to distinct water-flow rates, thermal loads, and site installation requirements.
For engineering projects requiring specific hot-water delivery temperatures, flow rates, ambient operating envelopes, or electrical configurations, the equipment can be sized around actual site operating parameters rather than relying solely on nominal capacity matching.

Typical Industrial Applications
Hotels & Resorts: Centralized domestic hot-water supply supporting guest rooms, commercial kitchens, and laundry operations.
Hospitals & Healthcare Facilities: High-reliability thermal supply for sterilization, sanitation, and domestic water loops.
Commercial Complexes & Multi-Family Residential: Centralized plant rooms serving high-occupancy buildings and district networks.
Food & Beverage Processing: Industrial process water, facility cleanup, and low- to medium-temperature preheating applications.
Agricultural Operations: Greenhouse climate conditioning, livestock facility sanitation, and aquaculture water heating.
General Industrial Manufacturing: Factory washdown circuits and process heating loops.
Control System & BMS Integration
Industrial plants require seamless communication between heating equipment and central plant management:
Controller Architecture
Microprocessor-based digital control unit designed for unattended commercial operations.
Communication Protocols
Standard RS485 interface supporting Modbus RTU protocols for direct integration into Building Management Systems (BMS).
Operational Modes
Multi-stage scheduling, automatic fault diagnosis, temperature logging, and frost protection management.
Safety & Frost Protection Mechanisms
To ensure operational resilience in rigorous weather conditions, the system incorporates multi-layer safeguards:
Refrigerant Circuit Protections: High-pressure and low-pressure safety cutouts, compressor discharge temperature monitoring, and phase-sequence protection.
Hydraulic Protections: Water flow switches to prevent dry running, anti-freezing cycle control during low ambient standby periods, and pressure relief valves.
Electrical Protections: Overload relays, over-voltage/under-voltage protection, and dedicated grounding continuity.
System Integration & Plant Room Design
An industrial heat pump operates as part of an integrated mechanical loop rather than a standalone appliance. Standard plant room layouts include:
Primary buffer tanks and domestic hot-water storage vessels.
Primary and secondary circulation pumps.
Automatic air vents, pressure relief valves, and expansion vessels.
Water filtration and chemical water treatment systems.
Flow meters, immersion temperature sensors, and pressure gauges.
Manufacturing, Quality Assurance & Factory Testing
Manufacturing procedures adhere to controlled industrial fabrication standards before export dispatch:
Refrigerant Circuit Pressure Testing: Nitrogen pressure holding and helium mass spectrometer leak detection.
Electrical Safety Verification: Dielectric withstand testing, insulation resistance checks, and grounding continuity validation.
Functional & Operational Run Testing: Simulated load testing of compressor staging, inverter modulation, fan cycling, and safety interlocks.
Hydraulic Pressure Testing: Water-side pressure integrity testing of heat exchangers and internal piping manifolds.
