Ebc12 modulating draft control pdf#
Thanks to Frank Philipse for supplying the above PDF datasheet.

Note the copper evacuation tube that can be seen as the spigot has been broken off. The EBC 12 can be used with EXHAUSTO Models RSV, BESF and BESB. This is achieved by modulating the speed of a chimney fan or ventilator.
Controlling the draft in mechanical draft system serving individual or multiple heating appliance systems. The Identification is on the dome with the sides plain black paint. Chimney Fans Controls Accessories Particle Filter US/CAN/JP Heat Recovery. Use The EXHAUSTO EBC 12 is a Modulating Fan Control used with single appliances to monitor and maintain a constant draft or pressure in a chimney or duct. The intended use of the control includes, but is not limited to: Controlling combustion air supply system. Frequency changer ECH11, IF amplifier EF11 x 2, demodulator, AGC detector and first audio stage EBC11, push-pull audio output EDD11 and rectifier EZ11. We have the complete line-up of valves from the set this valve was used in.
The triode is the first audio amplifier stage. One diode is for detection of the amplitude modulated signal and the other diode is the rectifier diode used to generate the AGC voltage to control the IF amplifier and possible the RF amplifier also.
