Core Technologies & Benefits

The IEU Series combines six advanced core technologies for ultimate indoor climate control:
1. DC Fan Motor: High-efficiency, ultra-quiet operation supported by double-layer sheet-metal housing and imported acoustic insulation, reducing noise levels to just 45 dB(A).
2. Multi-Stage Filtration: Initial, medium, and high-efficiency filters remove >90 % of circulating dust and >97 % of incoming PM2.5, ensuring every breath is clean.
3. Enthalpy Heat Exchange: Balanced temperature and humidity management with enthalpy efficiencies of up to 78 % in heating and 65 % in cooling, lowering energy consumption.
4. Compact & Lightweight Design: At 1615 × 650 × 1730 mm and 285 kg, the IEU Series fits tight mechanical rooms and ceiling spaces without compromise.
5. PID Control Loop: Precision temperature regulation (± 0.5 °C) for stable, comfortable conditions.
6. HD Color Touchscreen: The CLS7.0F controller provides intuitive, on-unit adjustments and real-time monitoring.

High-Performance Airflow

- Indoor Supply Air: 3000 m³/h of conditioned air to maintain consistent comfort.
- Internal Circulation Air: 2500 m³/h for rapid moisture removal and air mixing.
- Outdoor Fresh Air: 500 m³/h to dilute indoor pollutants and replenish oxygen.
- Exhaust Air: 500 m³/h to expel stale air and maintain balanced pressure.

Smart Sensing & Connectivity

A suite of high-precision sensors delivers the data needed for adaptive control: one air-quality sensor, four temperature/humidity sensors, and five NTC temperature sensors. Accuracy is ± 2 % with 99 % consistency, capturing metrics such as 24 °C, 56 % RH, PM2.5 levels, and CO₂ at 500 ppm.Built-in 4G connectivity and support for Modbus and dry-contact networking allow remote monitoring, over-the-air firmware updates, and integration with building management systems.

Modular Flexibility

Whether you need a standalone solution or a scalable network, the IEU Series adapts:

- Outdoor Modules: Multiple units can be paralleled to increase capacity or phased for redundancy.

- Indoor Units: Configurable in series or parallel to suit various floor plans.

- Third-Party Compatibility: Works seamlessly with other brands’ outdoor modules, giving you freedom in design and budgeting.
