Large Standard Series Energy Recovery Ventilator

Larger-format supply and extract air ventilation with energy recovery.

Overview

The large standard series energy recovery ventilator is a larger-format supply-and-extract unit for buildings with substantial ventilation demand. It coordinates incoming outdoor air and outgoing room air through the selected recovery arrangement, reducing the additional thermal treatment associated with fresh-air provision.

The catalogue describes a floor-standing installation that can be located in an equipment room or in a suitably protected outdoor location. Separating the larger ventilation equipment from the occupied zone can also help with acoustic planning.

Large-airflow equipment needs a system-level selection. Supply and extract quantities, fan pressure, core type, duct connections and service clearances are coordinated with the installation location and the building’s operating schedule.

PRODUCT DETAILS

Product Features

Larger ventilation duties

The standard series addresses air quantities beyond small room-level equipment. Model selection starts with the actual building ventilation requirement and the proposed distribution zones.

Coordinated air exchange

Supply and extract fans provide the two airstreams needed for the selected ventilation and recovery arrangement. Their duty is checked with the resistance of each connected air route.

Selected recovery type

The catalogue distinguishes recovery configurations within the range. Heat-only or total-energy requirements are confirmed for the actual model rather than inferred from the general series name.

Floor-standing equipment format

The cabinet can be arranged within a plant area instead of above an occupied room. Floor loading, handling access and the equipment footprint are included in layout planning.

Acoustic separation

Locating the larger unit in a suitable equipment space helps separate the fan source from occupied areas. The duct and outlet design still need to address noise transmission.

Outdoor protection where needed

The catalogue notes that outdoor installations require additional rain protection and other appropriate measures. Outdoor exposure suitability must be resolved for the complete supplied installation.

RNXHBQ and RNXHBX have different recovery characteristics; a dash means enthalpy recovery is not listed. The main dimensions apply to the corresponding paired model suffixes. Outdoor placement requires suitable weather protection, and the control enclosure location must follow the installation requirements.

WHERE IT WORKS

Applications

Suitable for larger offices, public buildings, hospitality and commercial ventilation systems using centralized air distribution. It is relevant where a floor-standing unit and substantial supply and extract ducts can be accommodated.

Provide air quantities, indoor and outdoor conditions, recovery preference, duct resistance and equipment-space constraints. Confirm filtration, weather protection and maintenance access for the chosen unit.
