![]() UL508- Standard for Industrial Control Equipment (17th Ed. Standard Equipment ADC150 Control Box XTP2 Pressure Transducer Stack Probe 6’ Silicone Tubing Specifications are subject to change without notice. For that reason, per 2018 IBC §3006, elevator hoistways connecting more than three stories must comply with the smoke and draft control door assembly requirements and be tested in accordance with UL 1784. Material The housing and cover is made of NEMA 1 rated ABS plastic. In the event of a fire, an unprotected elevator shaft acts like a chimney, spreading smoke through the subsequent floors. The control also features a post purge function (3 min) to evacuate the chimney system of residual flue gases after the appliance shuts down. End-switches in the damper actuator wired to the ADC150 ensure the damper must be fully open prior to allowing the appliance to operate. A single acting barometric control is designed for fuel oil fired equipment while a. Draft diverters/hoods and barometric controls are designed to provide varying degrees of draft control and allow dilution air to mix with the flue gases to reduce the potential for condensation. ![]() The ADC150 has an integrated damper relay that works with ENERVEX MFD (Mechanical Fireplace Damper) to automatically open the damper prior to fan intialization and close the damper after the appliance shuts down. As such, the draft rate is critical in maintaining this balance. The control has an integrated saftey system that assures the heating appliance(s) is shut down in case of insufficient draft after 15-180 seconds (user adjustable). It provides a 10-120V AC power to single phase fans and 0-10V DC control signal to control 3-phase fans via a variable frequency drive. A schematic diagram of a furnace draft or induced draft control is shown in the figure below. Description The ADC150 monitors the draft in a chimney system via a connection to a pressure transducer (XTP2) attached to the chimney, and maintains the draft by modulating the fan speed. The ADC150 is typically used to control the draft of a gas-fired, sealed fireplace or water heaters. At the same time, the draft demonstrates an obvious intention to strengthen government control over China’s technology and information ecosystems. ![]() It can control the fan speed directly or via a Variable Frequency Drive (VFD, sold seperately). The ADC150 can be used with models RS, RSHT, and GSV fans. Product Information ENERVEX Fan Control ADC150 Use The ENERVEX ADC150 is a Modulating Fan Control used with up to 2 appliances to monitor and maintain a constant draft or pressure in a chimney or duct. ![]()
