When it comes to fire protection, our ELO-231 and K11-231 Sprinklers provide you with the ultimate peace of mind. The K11-231 models, including the K11-231B and K11-231FRB upright storage sprinklers, replace the upright standard and quick response ELO-231B and ELO-231FRB models, offering enhanced performance for high-density applications. Both the ELO-231 and K11-231 sprinklers are automatic, upright, pendent, and frangible bulb type sprinklers that produce a hemispherical water distribution pattern. With an extra-large orifice designed specifically for storage occupancies, these sprinklers are engineered to control high-challenge fires with relatively low pressure. For added versatility, incorporating a guard and shield with an ELO-231 or K11-231 sprinkler transforms it into an intermediate level version. Choose our advanced sprinkler solutions for reliable fire protection tailored to your needs.
