ESBE ATA Self Contained Thermostatic Expansion Draft Regulator

The ESBE Draft Regulator by Danfoss is a self contained thermostatic expansion control device intended to regulate the temperature of solid fuel fired boilers without requiring any electrical installation or complicated linkage. The thermostatic control head senses the boiler temperature and the air damper position, controlling combustion air flow. The ESBE Draft Regulator is fully adjustable within the range of 100 - 195 F (40 - 90 C).

Connection is through a screwed boss directly into the boiler waterway. ESBE series ATA draft regulator is also available in European G thread connection. Contact Danfoss for further information.

Under normal service conditions maintenance is not required, however, should the need arise the thermostatic element (372010) may be replaced after first removing the regulator from immersion pocket.

The regulator may be mounted either vertically or horizontally with the chain connected to the air damper with the lever and chain adjusted so that the air damper just closes when the required temperature has been achieved. Fine adjustment of boiler temperature is made by rotating the control knob, each graduation of the knob corresponds to 50 F (10 C) dependent on operating range.
