Problem: Traditional chimneys and louvers cannot adjust to changes in burner firing rates, temperatures, winds and building pressures that can negatively affect burner performance. What’s more, these fixed systems are often unable to successfully handle common venting of multiple heaters.
 
Solution: The CPC-3 functions as the brains of Tjernlund’s “smart” mechanical vent systems. It simultaneously monitors and adjusts fan speed to maintain optimum draft and/or combustion air. This second generation, patented controller sets new standards for venting system control, ease of installation and operation.

 

Modulating Draft Systems for Boilers and Water Heaters
Featuring the CPC-3 Controller and Auto-Draft® VSAD-Series Inducers or VSUB-Series Universal Blowers

Problem: Erratic draft is the most common cause of heater performance and operation problems. Traditional chimneys cannot adjust to varying winds, temperatures, building pressures and burner firing rates. A chimney has even a tougher time providing stable draft when it is serving multiple heaters. Fan assisted and condensing heaters have specific draft requirements that are not as forgiving as atmospheric heaters.

Solution
: Specify the CPC-3 Controller to automatically monitor and modulate the speed of either VSAD-Series Inducers or VSUB-Series Universal Blowers to maintain optimum draft. Patented CPC-3 controlled draft systems feature 100% modulation and also include the ability to independently modulate a separate combustion air blower and control a motorized combustion air louver. Vent heaters hundreds of feet in any direction.

Auto-Draft® FSAD-Series Fixed Speed Inducers
For single or multiple heaters with draft hood/diverter or barometric draft control.

Exterior mount fixed speed inducer is suitable for vertical and side wall venting. Assures a negative pressure throughout the entire vent system. Features integral stainless steel handles and hinged housing with removable hinge pin for ease of installation and service. Integral tilt switch stops fan operation if housing is opened. Includes PSA-1 Fan Proving Switch
 

Modulating Combustion & Make-Up Air Systems
Featuring CPC-3 Controlled Blowers and Fans

Problem: Conventional combustion and make-up air louvers do not perform consistently. Simply having a large opening to the outdoors does not guarantee correct volumes of combustion air. Depending on wind speeds and direction, mechanical rooms may get significantly more or less air than is actually needed. As with chimneys, combustion air openings must be sized based on the combined firing rate of all heaters
within the mechanical room. In reality, all heaters rarely if ever operate at the same time. Uncontrolled combustion air can cause problems ranging from frozen pipes to flue gas spillage and flame roll-outs.

Solution: Tjernlund’s modulating combustion & make-up air systems always ensure proper air supply, regardless of the number of heaters operating and regardless of outdoor conditions.

Modulating Dryer Venting Systems
Increases efficiency and reduces energy by automatically adjusting exhaust based on the number of dryers in use.

 

Problem: When commercial clothes dryers are
common vented the exhaust from one dryer fights
another. Residential high rises have the same problem
of properly venting multiple dryers without installing
individual exhaust vents.
Solution: CPC-3 controlled inducers and blowers
modulate to "perfectly" exhaust common vented
clothes dryers, regardless of the number of dryers
operating. They automatically compensate for
changing pressures, temperatures and winds.
Controlled exhaust results in faster drying laundry.

Overcome Exhaust Vent Design Restrictions

Individual vents can be expensive, if not impossible
to install in multi-story buildings. Laundry room
locations often force exhaust vent lengths to exceed
the dryer manufacturers’ recommendations. CPC-3
controlled exhaust vents can run hundreds of feet
in any direction and vent diameter can be reduced
by up to 50%.
