Buy PremAIR-NA Counterflow HRV Unit | CSA Certified

Performance and Airflow for Demanding Projects

The PremAIR-NA unit is engineered for powerful and continuous operation, ensuring optimal air exchange and recovery in extensive ventilation systems.

• Maximum SRE: Achieves a superior recovery efficiency (SRE) of up to 90.5 percent, maximizing energy savings by utilizing heat from extracted air.
• High-Capacity Airflow: Capable of delivering up to 261 CFM (123 L/s) supply air at 0.4 inch w.g. (100 Pa) external static pressure, suitable for larger service areas.
• EC Motor Technology: Features high-efficiency EC centrifugal fans with backward curved blades, ensuring high volume airflow with minimized electrical consumption.
• Certified Reliability: Performance tested according to the stringent CSA C439-18 standard and HVI Certified, confirming its technical capabilities.

EPP Casing and Installer-Focused Design

The unit’s construction simplifies every phase, from transport and mounting to long-term maintenance, while guaranteeing superior thermal and acoustic isolation.

• Hi-Tech EPP Casing: Made from Expanded Polypropylene (EPP), the modern casing provides high mechanical resistance, exceptional thermal, and crucial acoustic insulation, contributing to a silent operation.
• Lightweight Advantage: Despite its high capacity, the unit features a light-weight construction, weighing only 32 kg, significantly easing handling and installation for technicians.
• Quick Connectivity: Equipped with 160mm (6 1/4 inch) top ports featuring rubber seals, facilitating fast, secure, and air-tight connections to ductwork.
• Easy Maintenance: Designed with easy access points for core and filters, minimizing the time required for routine service. Wall mounting racks and feet are included.

Filtration Standards (MERV 7 and MERV 13)

The HRU-PremAIR-NA supports dual-stage air quality management via two distinct filter options, providing flexibility based on project requirements.

Intelligent Control and Maximum Frost Protection

The advanced PCB enables versatile control methods—both wired and wireless—and employs robust strategies to ensure balanced ventilation remains operational even in severe winter conditions.

Connectivity and Smart Ventilation

• Wired/Wireless Control: Units can be operated via an advanced wired control panel (e.g., HRQ-BUT-LCD-P5) or remotely through the built-in Wi-Fi/Bluetooth module using a dedicated mobile application (Android, iOS) or cloud service.
• Demand-Controlled (AUTO) Mode: Optimized for energy efficiency with the optional external CO2 or RH sensor (HRQ-SENS-CO2RH-P). The unit automatically adjusts fan speed based on ambient air quality measurements, ventilating only when necessary.
• Time-Based Functions: Supports scheduled operation with four core speeds (PAUSE, LOW, MEDIUM, HOME) and programmable time modes (EXIT, PARTY, AIRING).

Three Available Defrosting Strategies

Continuous, balanced operation during frost conditions is ensured by selecting one of three available frost protection systems:

1. Recirculation System: The most powerful defense, capable of operation down to -25 degC by temporarily redirecting exhaust air to the intake.
2. External Electric Preheater: An optional round duct heater (HRQ-HDE-CO1-P) provides balanced flow continuity below -3 degC.
3. Fan Unbalance: Reduces the supply fan speed to prevent freezing, suitable for temperatures between -3 degC and +1 degC.
