GRV Filtration Systems for Gun Ranges
Other companies still install recycled air systems that use a portion of the old exhausted air and bring it back into the range after it is filtered. Filters can remove contaminants, but they do not eliminate the smell of smoke and negatively impacts the overall customer experience. The risk of contamination and dirty air is too great to still design systems like these. GRV has solved this by designing Range Ventilation Systems using Energy Recovery units.
1.) Energy Recovery Ventilation (ERV)
Energy Recovery Ventilation (ERV) is the energy recovery process of exchanging the energy contained in contaminated exhausted range air and using it to treat (or precondition) the incoming outdoor ventilation air in commercial HVAC systems.
During the warmer seasons, the system pre-cools and dehumidifies while humidifying and pre-heating in the cooler seasons. The benefit of using energy recovery is the ability to meet the ASHRAE Ventilation & Energy Standards, while improving indoor air quality and reducing total HVAC equipment capacity.
ERV systems allow for the indoor environment to maintain a relative humidity of 40-50%. This humidity range can be maintained under essentially all conditions.
2.) Purge Systems
100% Fresh air is introduced to the range and the exhaust is filtered through Merv Pre Filters and HEPA Filters before being released outside. Purge systems are less expensive up front, but they are not as efficient as ERV systems over time.
GRV can handle any size project from Military to commercial to private ranges in basements.
Private indoor ranges present special challenges that GRV can provide cost effective solutions for. Heating and cooling is not always needed for private ranges-Just filtration, which can reduce overall cost of installation.
