Product catalog summary
Introduction
The HRU Series Heat Recovery Units are designed to enhance air circulation and energy efficiency, complying with the Ecodesign Directive 2009/125/CE. These units are crucial for systems requiring forced ventilation to maintain air quality while minimizing energy costs by recovering over 85% of energy from expelled air.
Specifications
The HRU units are versatile, operating efficiently in both summer and winter. They integrate with systems like convector-fans, air-conditioning units, and underfloor heating. Available in four models, they support air flow rates from 1000 m3/h to 4000 m3/h, suitable for various installations including false-ceiling and ducted systems.
Main Components
  • Casing: Constructed from aluminium with fibreglass reinforced corners and insulated panels.
  • Heat Recovery Unit: Made of aluminium, offering over 85% efficiency with features like a modulating by-pass damper.
  • Electrical Box: Pre-wired for fan control with 0-10 V input.
  • Electric Fan: Features a centrifugal fan with EC motor, thermal protection, and a maximum operating temperature of 55°C.
  • Filter: M5 efficiency, side-removable.
Technical Data
The units provide thermal recovery capacities from 7.6 kW to 30.3 kW in winter and 1.5 kW to 6 kW in summer, maintaining supply air temperatures of 16°C in winter and 27°C in summer.
Optional Accessories
Accessories include re-heating elements, cooling coils, dampers, and anti-freeze thermostats.
Procedures
The HRU can be equipped with electronic controls for performance optimization, managed via remote terminals with features like fan speed adjustments and modulating control.
Standards and Recommendations
Specific power supply configurations and safety measures are required, with recommendations for using the Roccheggiani regulator for optimal performance.
Key Data from Tables
Detailed dimensions and specifications for HRU models are provided, including control parameters for fan speed and valve operations based on environmental conditions.
Performance Ratings
Efficiency and thermal recovery capacity are detailed under various conditions, with data on water flow rates and pressure drops.
Recommendations
  • Select HRUs based on environmental conditions to optimize efficiency.
  • Regular maintenance is recommended for optimal performance.

Unita di Recupero Calore ad Alta Efficienza Heat Recovery Unit HRU Unita di Recupero Calore ad Alta Efficienza High Efficiency Heat Recovery Unit Introduzione Introduction Le nuove unita di recupero calore serie HRU rispondono alle esigenze di ricambio dell'aria e risparmio energetico in un vasto campo di applicazioni. In conformita ai requisiti della Direttiva 2009/125/CE Ecodesign per le unita di ventilazione con efficienza Erp2018 (direttiva 1253/2014), nell' impiantistica evoluta, per il controllo della qualita dell'aria, e necessario realizzare una ventilazione forzata per il ricambio dell'aria, che, tuttavia, comporta l'espulsione dell'aria climatizzata e l'immissione di aria esterna, causando cosi un maggior consumo energetico ed un aumento dei costi. Lo scopo dei recuperatori termici e quello di minimizzare il costo del ricambio dell'aria. Utilizzando un recuperatore ad alta efficienza si riesce a risparmiare piu dell'85% dell'energia che, diversamente, andrebbe perduta con l'aria viziata espulsa. Essi consentono di unire un elevato comfort ambientale con un elevato e sicuro risparmio energetico. Le unita di recupero HRU possono funzionare sia nella stagione estiva che in quella invernale e si integrano in modo ottimale ai sistemi tradizionali realizzati con ventilconvettori, unita di condizionamento, radiator e sistemi a pavimento. La serie si articola su 4 grandezze con portate d'aria che vanno da 1000 m3/h a 4000 m3/h. La tipologia costruttiva e particolarmente indicata per installazioni a controsoffitto per essere canalizzata al fine di consentire l'immissione ed il prelievo dell'aria direttamente dall'ambiente interessato. I recuperatori trovano impiego in ambienti civili, commerciali, uffici, negozi, locali pubblici e sale fumatori. The new HRU Series HEAT RECOVERY UNIT satisfies the demands of air circulation and energy savings in a wide range of applications. In compliance with the requirements of Ecodesign Directive 2009/125/CE for ventilation units with efficiency Erp2018 (Directive 1253/2014), in advanced system design, for the control of air quality, it becomes more and more important to change the air through forced ventilation. However, this involves expelling conditioned air and the introduction of fresh air from outside, leading to greater energy consumption and a consequent increase in operating costs. The purpose of heat recovery units is to minimise the cost of changing air. By using a high efficiency heat recovery unit, one can save more than 85% of the energy that would normally be wasting when expelling stale air. These units combine high levels of comfort in the occupied space together with large energy savings. The HRU units are designed to operate in both summer and winter and are total ly suitable for use in traditional systems where convector-fan systems, air-conditioning units, radiators and underfloor fancoil units are used. The series is available in 4 different models, with a nominal air flow rates ranging from 1000 m3/h to 4000 m3/h and are particularly suitable for false-ceiling installation, to be ducted and to allow air supply and air removal from the rooms. This range of units is particularly suitable for use in civil and commercial premises, offices, shops, bars and restaurants, essential in smoking areas according to passive-smoking regulation.
