ECOFlEx 90+ PaCkagED MODulating Fan-POWErED ECOnOMizEr
The EcoFlex 90+ may be the single design that combats all the challenges in the typical economizer. It opens the energy recovery up to practically any combustion appliance application. With the EcoFlex 90+ system you can now view the application as a complete “boiler plant” as the full load to work with, instead of one economizer per boiler. And the “boiler plant” can consist of a combination of boiler types such as forced draft boilers and atmospheric water heaters that utilize a single modulating demand-controlled economizer. The bottom line is: design flexibility, reduced emissions, improved boiler efficiency, high return on investment. •	 Single	EcoFlex90+	system	for	single	and	multiple	boilers •	 For	atmospheric,	fan-assisted	or	forced	draft	boilers—or	any	 combination •	 Always	perfect	boiler	draft	conditions •	 Variable	or	constant	water	flow •	 Reduces	and	maintains	low	emissions,	including	NOx •	 Spark-resistant	construction	with	TEFC-motor	with	direct	drive	 and true variable speed •	 Easy	programming	of	essential	functions •	 Easy	upgrade,	fast	payback!

FluE DraFt anD CO SaFEty MOnitOr

The EBC 35 draft control with CO-monitor is an easy way to safeproof your boiler facility. An integrated Proven Draft Switch function assures that if sufficient draft cannot be maintained, the control will lock out the boiler(s) within an adjustable time period. The CO transmitter with LCD display monitors CO levels on location. The CO monitor meets OSHA and other safety requirements. •	 CO	monitoring	and	CO	level	display •	 Daisy-chain	multiple	CO	monitors •	 0	to	125	ppm •	 Boiler	safety	interlock •	 Draft	control	and	monitoring •	 Minimum	2-year	sensor	life	span For more information call (800) 255-2923 or visit www.enervex.com
