Key Features

01/

EVI Technology for Low-Ambient Operation: Enhanced Vapor Injection scroll compressors combined with an auxiliary sub-cooler maintain 100% heating capacity at -12°C ambient and operational output down to -25°C.

02/

Modular Multi-Circuit Redundancy: Units integrate 2 to 4 independent refrigeration circuits. If one circuit undergoes maintenance, remaining circuits maintain baseline system operation, eliminating single-point catastrophic failure.

03/

Intelligent Defrost Logic: Dynamic defrost algorithms monitor ambient humidity, coil temperature, and running duration to initiate defrost cycles only when frost accumulation impacts thermal exchange, minimizing heating interruptions.

04/

BMS Integration & Open Protocols: Onboard programmable logic controllers (PLC) support standard RS485 ports with Modbus RTU, BACnet MS/TP, and TCP/IP protocols for seamless central Building Management System integration.

Technology & Working Principle

Refrigeration Cycle Mechanics: The system operates on a standard vapor-compression cycle. During cooling, the heat exchanger acts as an evaporator, absorbing heat from building chilled water loops and rejecting it via outdoor condensers. In heating mode, a 4-way reversing valve switches refrigerant flow, extracting latent heat from ambient air down to -25°C and transferring it to the hydronic heating loop.

Capacity Modulation: Multi-compressor parallel configurations and inverter-driven fan staging allow multi-stage capacity modulation (25% - 50% - 75% - 100%), maintaining chilled water temperature within +/- 0.5°C of setpoint and avoiding frequent compressor cycling.

Applications

Commercial Real Estate:

Multi-tenant office buildings requiring simultaneous zonal cooling and heating via flexible 2-pipe or 4-pipe hydronic setups.

Hospitality (Hotels & Resorts)

Continuous domestic hot water pre-heating combined with guest room climate control, utilizing heat recovery options to recycle waste condenser heat.

Healthcare Facilities

Hospitals and laboratories demanding strict temperature stability and redundant backup circuits for critical cleanroom HVAC loops.

Light Industrial & Data Centers

Process cooling loops requiring 24/7 continuous year-round operation under high thermal loads.

System Solutions

Hydronic Schematic Integration: Fully compatible with primary-secondary pumping loops, variable primary flow (VPF) setups, and thermal storage buffer tanks.

Hydraulic Module Options: Available with factory-installed dual inverter-driven water pumps (duty/standby configuration), expansion vessels, flow switches, and safety pressure relief valves, drastically minimizing on-site mechanical piping labor.

Compliance & Certifications:
Manufactured under ISO 9001 Quality Management and ISO 14001 Environmental Management standards.
Electrical safety and performance conformity compliant with CE (PED/LVD/EMC), Eurovent, and ETL/UL regulatory requirements.

FAQ

Q: What is the COP degradation curve of the unit at -15°C ambient temperature?

A: At an ambient temperature of -15°C and a leaving water temperature of 35°C, the standard EVI model maintains a heating COP between 2.1 and 2.4. Full test curves across various ambient and water temperatures are available in our downloadable Engineering Technical Manual.

Q: Can these units be installed in parallel for large district or campus-style HVAC loads?

A: Yes. Up to 16 identical or mixed modular units can be linked together under a single master controller using a CAN-bus network, allowing automatic lead-lag rotation and total load balancing.

Q: What is the standard lead time for standard catalog units vs. customized OEM orders?

A: Standard catalog units (380V/50Hz) typically ship within 25 to 30 business days. Custom OEM builds, specific refrigerant requirements, or special coastal corrosion packages require 45 to 60 business days following engineering drawing sign-off.

Q: What technical documentation is supplied with each shipment?

A: Each shipment includes comprehensive documentation: an Installation & Operation Manual (IOM), electrical wiring diagrams, hydraulic schematic drawings, factory test run reports, and CAD/BIM (Revit) files.
