Publication number: 20220349613Abstract: An exposed high induction supply air duct is provided and is adapted to be installed in an open ceiling environment. Conditioned air is diffused from the supply air duct through an array of nozzles disposed along the length of the supply air duct. At the same time, existing air in an open space underlying the duct is induced upwardly towards the nozzles where the existing air is efficiently mixed with the supply air being exhausted by the nozzles.Type: ApplicationFiled: April 28, 2021Publication date: November 3, 2022Applicant: Captive-Aire Systems, Inc.Inventors: William Brian Griffin, Nicholas I. Perry, Kyle D. Thompson, Joshua J. Hess

Publication number: 20210372145Abstract: The present invention entails a rooftop exhaust system for a building. The exhaust system includes a motor that is configured to directly drive a fan. The fan during the course of operation generates a negative pressure on the upstream side of the fan. This negative pressure is utilized to induce outside cooling air into a shroud that partially encloses the motor. Cooling air passing through the shroud contacts the motor and heat associated with the motor is transferred to the cooling air after which the cooling air exits the shroud.Type: ApplicationFiled: June 2, 2020Publication date: December 2, 2021Applicant: Captive-Aire Systems, Inc.Inventors: Joshua J. Hess, William Brian Griffin

Publication number: 20210146180Abstract: The present invention relates to a fire extinguishing system for a commercial kitchen. The fire extinguishing system comprises a canister containing a fire extinguishing agent and a gas expellant. In the event of a fire or conditions that pose a threat of a fire, the internal pressure in the canister is utilized to actuate a main control valve of the canister which releases the fire extinguishing agent from the canister.Type: ApplicationFiled: November 19, 2019Publication date: May 20, 2021Applicant: Captive-Aire Systems, Inc.Inventors: William Brian Griffin, L. Kenneth Bray, III, Nikhil Ramesh

Patent number: 10953254Abstract: Disclosed herein is a system and process for monitoring and controlling fire suppression systems in commercial kitchens. Repeatedly various components of the fire suppression systems are tested for faults. When a fault is detected in a particular component, the fault is communicated through a communications module associated with the commercial kitchen via the internet to one or more remote servers. Upon receiving information indicating a particular fault, the one or more remote servers acts to alert interested parties of the default.Type: GrantFiled: December 5, 2017Date of Patent: March 23, 2021Assignee: Captive-Aire Systems, Inc.Inventors: William Brian Griffin, William Earle Glaub, Brady Jay Ambrose, Jesse Beard

Patent number: 8777119Abstract: A heated air makeup unit comprising a heating chamber with a modulated furnace one or more non-modulated furnaces air temperature control and efficient furnace operation over a wide heating rate range. The utilization of indirect fired furnaces in the heated air makeup unit is disclosed. A control system is included to provide control of heated air temperature to within +/?1 F.° using continuous control of the heating rate of the modulated furnace and stepwise activation and de-activation of the non-modulated furnaces in response to heating demand. A programmed combustion air flow controller programmed to provide optimal airflow for any gas flow in a flow range of a modulating gas valve is provided to assure combustion efficiencies of at least 83%.Type: GrantFiled: October 2, 2009Date of Patent: July 15, 2014Assignee: Captive-Aire Systems, Inc.Inventors: William Brian Griffin, Brandon Charles Wellington
