Small commercial buildings need the same fresh-air performance as large ones, but they rarely have the roof space, mechanical room or installation budget to match. RGSP-X is a compact outdoor energy recovery ventilator (ERV) built for exactly that gap: high-performance ventilation for single and multi-zone applications, without giving up flexibility or ease of integration. It pairs up to 90% sensible heat recovery with year-round operation in extreme cold, and a streamlined design that makes it simpler to assemble, install and tie into building controls. Here is what that looks like in practice.
Compact by design
RGSP-X has a small footprint that suits both single-zone and multi-zone applications. For designers working on retrofits, low-rise commercial or buildings with limited rooftop real estate, that means one less layout compromise.
A smaller unit is also easier to place around existing equipment, curbs and service clearances, which matters most on tight roofs where every square foot is already spoken for.
Up to 90% sensible heat recovery
RGSP-X recovers up to 90% of the sensible heat in exhaust air and transfers it to incoming outdoor air. That cuts the load on downstream heating and cooling equipment while still meeting ventilation requirements.
The performance is designed to hold up across all four seasons, not just at a single rating point. Owners get consistent energy savings through winter, summer and the shoulder seasons in between.
Built for extreme climates
RGSP-X is designed to operate in winter conditions down to -40°F, which is also -40°C. For projects across Western Canada and the Territories, that is a practical rating, not a marketing figure: it covers the cold snaps that sideline equipment designed for milder markets.
Reliable cold-weather operation means building owners can count on continuous fresh air and heat recovery during the months when both matter most.
Simplified assembly
RGSP-X is built from standard parts with pre-engineered locations, so every unit goes together the same way. The result is an easy, consistent and cost-effective assembly process.
That consistency carries through to the job site. Pre-engineered configurations reduce custom work, shorten installation time and make the unit easier for contractors to integrate with the rest of the system.
Flexible integration
RGSP-X comes in six unit sizes, from the RGSP-X 500 up to the RGSP-X 1600 (roughly 500 to 1,600 CFM nominal), so the unit can be matched to the space rather than the other way around. Other options include:
- BACnet capability, for straightforward connection to building automation systems
- 1″ to 2.5″ external static pressure (ESP) range, giving designers room to work with a variety of duct layouts
Together, these options let one product line cover a wide range of small commercial projects.
