Draft Control
Draft and Pressure. Under Complete Control.

No other mechanical draft and pressure control solutions offer a more straightforward installation and greater adaptability to changing conditions. 

ENERVEX commercial controls give you precise and safe control of your commercial exhaust and ventilation processes, including protection against:

  • Erratic draft or pressure
  • Inconsistent or uncontrolled supply make-up air / combustion air
  • Un-controlled flow rates in a vent
  • Mechanical or electrical failures

All of our controllers are built to integrate seamlessly with our mechanical draft fans and ventilators. This modular approach reduces risk and guesswork during the design process, and delivers flexibility to add what you need, when you need it. Safe, efficient, easy to install, and easy to maintain.

EBC 31 Modulating Pressure Controller—multi-use draft and pressure controller with integrated web server and remote access
EBC 31

A sophisticated multi-use draft and pressure controller with integrated webserver and remote access used with fans and dampers to monitor and maintain a constant pressure in commercial boiler and building applications.

EBC 35 Modulating Pressure Control and CO Monitor—varies the speed of a fan(s) or the position of an actuator
EBC 35

A sophisticated multi-use draft and pressure controller and CO-monitor with integrated webserver and remote access used with fans and dampers to monitor and maintain a constant pressure in commercial boiler and building applications.

EBC 24 Modulating Fan Control—multi-use draft or pressure controller
EBC 24

A safe, efficient, easy set-up draft control solution built for boilers, water heaters, and mechanical rooms. Integrated Modbus protocol.

MEC 24 Modulating Pressure Control—simple modulating fan control for multi-story applications
MEC 24

A modulating pressure control that provides superior pressure control in single- or multi-story building applications such as clothes dryers, bathrooms and kitchens.

EBC 24X Motor Power Relay—used with a main control panel to operate multiple single-phase intake or exhaust fans.
EBC 24X

The EBC 24X motor power relay is used in conjunction with a main control panel to operate multiple single-phase intake or exhaust fans.

ES12 Relay Box—multiple appliance relay control panel
ES12

A flexible, multi-appliance relay control panel that is used to interlock up to 4 appliances. Requires an EBC control..

MSC E3 EDrive Motor Controller— controls and adjusts the speed of fans and ventilators
EDrive E3

A full featured, industrial-type motor controller for indoor/outdoor use (NEMA 4X) programmed specifically to control and adjust the speed of ENERVEX fans and ventilators using Electronically Commutated (EC) Motors or Induction Motors.

BDC 8 Fan and Damper Controller—maintains fan speed for gas and oil-fired boilers, fireplaces, water heaters, and furnaces
BDC 8

A simple fan and damper control for gas- and oil-fired boilers and water heaters that maintains a set fan speed where modulation is not required. 

PDS Proven Draft Switch—fixed set-point differential pressure switch
PDS

A fixed set-point differential pressure switch that protects your heating appliances against insufficient draft and unsafe draft conditions during a mechanical or electrical failure.

OPS Over-Pressure Switch—over-pressure draft protection for boilers and over-draft control system
OPS

Provides superior over-pressure draft protection for a boiler.

XTP Differential Pressure Sensor—external bi-directional pressure transducer that monitors draft in a chimney or pressure in a duct
XTP

An external bi-directional pressure transducer for monitoring draft in a chimney or pressure in a duct.

BDC 26 Redundancy Controller—used when an option to operate a redundant mechanical draft system is required
BDC 26

The Redundancy Controller is used when an option to operate a redundant mechanical draft system is required. It allows the safeties to be bypassed in case of an EBC 30/31/35 failure.
