The Ventacity Systems VS1000RT is the most intelligent and efficient rooftop heat recovery ventilator (HRV) available, engineered for harsh outdoor application and easy maintenance over a long service life. It is the only UL, CSA and Passive House certified counterflow HRV available in North America.
With its aluminum counter flow heat exchanger core, the VS1000RT transfers up to 93% of the heat between intake and exhaust air streams, which is 43% more than the typical efficiency of heat exchangers using cross flow cores or enthalpy wheels.
Exceptional efficiency means exceptional energy savings for heating and cooling, and the efficiency of the VS1000RT doesn’t stop with core design. Ventilation fans can be major energy consumers but our fans incorporate electronically commutated motors (ECMs) and backward curving fan blades, (they’re aerodynamically shaped like an airplane wing to reduce air turbulence) reducing the power required for air movement while also reducing noise.
The superior efficiency of the VS1000RT is further proved by engineering details, such as positive sealing doors, heavy insulation and the elimination of thermal bridges to the exterior of the units (i.e. would-be pathways for energy to escape and be wasted). It also features a built-in economizer eliminating the added expense and effort of installing an add-on.
The VS1000RT is also the most intelligent HRV on the market. It has eight internal air pressure sensors, five temperature sensors and a sophisticated controller that can be set to maintain positive, neutral or negative pressure within a building, helping to control the flow of air between the inside and outside and within the structure.
Perhaps more importantly, the VS1000RT’s intelligent controls can be connected to sensors throughout the building to detect levels of CO2, VOCs, relative humidity and occupancy and then opitimize ventilation, providing just the right amount of fresh air when and where needed for maximum health and comfort.
The controller can be programmed with sophisticated rules that can be scheduled by times of day and days of week. For example, ventilation can be shut off completely after office hours or boosted when CO2 levels are high.
The VS 1000 RT also includes:
From the outset, we designed the VS1000RT to stand up to harsh rooftop environments. It is also perfectly suited for installation adjacent to a building or its basement. Precision construction and air tight door seals exclude dust and moisture. Its galvanized, powder coated steel case will stand up to years of weather exposure.
Our engineers spend countless hours on rooftops understanding the installation process so the VS1000RT is designed to be easy for crane operators, HVAC installers and electricians to install and maintain. It fits directly over the roof curb of most 5 ton RTUs. Ducting can be routed to ports on either the ends or the bottom of the unit, minimizing the need to modify ductwork. Changing filters is easy with the VS1000RT. Simply open the side door, slide out the old filters and slide in the new.
