If you want your commercial boilers and water heaters powered by a mechanical draft system inside the the boiler room, ENERVEX has you covered.
Available in small, medium and large formats, ENERVEX's Inline Chimney Automation System (CASI) is a great option for buildings that are tall, that feature sidewall venting, or where the power venter must be installed inside the building. It is a state-of-the-art demand-controlled exhaust system designed for commercial boilers and heaters which optimizes any heating appliance’s efficiency by actively controlling draft. Its high temperature variable-speed draft fan and motor controls regulate draft by modulating the fan.
Depending on the system size, the CASI system consists of an IPVB or TDF Power Venter and the EBC31, Modulating Fan Control. The EBC31 maintains a constant draft for the heating appliances by modulating the speed of the Power Venter. An MSC EDrive Motor Speed Controller is also part of the system when IPVB is equipped with a 1HP motor or larger. The MSC is always a part of a system utilizing the TDF Power Venter, which uses EC motors.
Each appliance is interlocked with the EBC 31. A call for heat activates the power venter and releases the burner once an adequate, pre-set draft is established. The sequence is repeated every time a new heating appliance calls for heat. When an appliance shuts down, the chimney fan will slow down while still maintaining the draft setting. When the last appliance shuts down the chimney fan will operate in post-purge mode for a preset time period.
The integrated proven draft function will shut down the entire system in case of a power failure to the chimney fan or the MSC Motor Speed Controller or mechanical failure. During a following call for heat, the Operating Priority function will detect if one or more appliances can be operated safely and with proper draft. If so, the appliance(s) will be able to operate without fan operation. After two (2) hours, fan operation is checked and if present, the control will go back to normal operation. Otherwise, it will continue to operate in Operating Priority mode. The self-check is repeated every two (2) hours infinitely. During a period without fan operation, the control is in alarm mode.
If the chimney fan has been out of commission for seven (7) days, the Bearing Cycle Activation function will operate the fan at a low speed for a short time. This is automatically repeated every seven (7) days, if the fan has not been operating.
Any errors detected during operation are shown on the digital display screen.
