FLUE DRAFT AND CO SAFETY MONITOR

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!

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

XTRU-THERM® PLUS BY PERMA-PIPE®
SOLUTIONS FOR A GREENER ENVIRONMENT XTRU-THERM	 PLUS,	 the energy saving Green Pipe with the Aluminum Diffusion Barrier, reduces CO 2 emissions, improves thermal efﬁciency and is suited for LEED project applications. It is the most advanced polyurethane foam insulated piping system for fluids from cryogenic temperatures up to 250°F.

EFFICIENCIES UP TO 99% AT FULL INPUT

RBI’s Futera Fusion condensing, high efficiency boilers operate with efﬁciencies up to 99% at full input. The ideal choice for applications with low operating, return, or make-up water temperatures, Fusion boilers fully modulate to precisely match the energy input to the heating load without over-ﬁring and wasting fuel for extremely high part-load efﬁciencies. Available in sizes from 500 MBH to 2000 MBH, Fusion boilers feature a solid stainless steel secondary heat exchanger which operates in full condensing mode at all times, while a state of the art temperature mixing system protects the boiler’s primary heat exchanger.
