Reduced operating costs start with smart controls,
performance analytics and easy to maintain features.
• Pre-commissioned: Installers save time commissioning
equipment when they choose Rebel Applied with
preloaded jobsite specic controls set points and
congurations.
• Refrigeration Monitoring: Optional refrigeration
sensors enable quick direct digital measurement of the
performance of the refrigeration cycle. This ehances
servicability with real time discharge, liquid and
suction refrigeration conditions with calculated subcool
performance at the unit controller. These sensors also
enable a condenser service status to indicate coil
cleaning is need or a condneser fan failure may be
present. Additionally this provides a low charge alarm to
indicate a leak or system maintence may be required.
• Direct-dive ECM Fan Arrays: Direct-dive ECM fans
provide redundacy and operating feedback to the
controller to annunciate alarms when motor replacement
is required.
• Intelligent Controls: Monitor, and troubleshoot equipment
remotely with intelligent Equipment and leverage local
control features like airow measuring on all fans, real
time electronic lter pressure transducer monitoring and
compressor envelope protection to prevent failures and
prolong equipment life.

Operating expenses go way beyond energy consumption;
To optimize the lifecycle cost of Rebel Applied rooftops we
designed in features that make it easier to service, saving time
and money for building owners and operators.
• Direct-dive ECM Fan Arrays: ECM Fans reduce the start-
up process by eliminating belts, and sheaves that have
to be adjusted at start up and eliminates shipping blocks.
Direct-dive ECM fans also o󰀨er a low maintenance
cost by eliminating belt maintenance activities such as
tensioning and replacement, sheave alignment, or fan
bearings lubrication service. Since Rebel Applied uses
direct-drive ECM fans for all supply, return and exhaust
fans, annual service is reduced by at least 2 hours of
service time per unit per year. Additionally, all ECM fan
arrays are provided with quick connect wiring that is
easy to disconnect and only 4 bolts for mounting which
simplies and saves time in the event of replacement.
• Refrigeration Options: Rebel Applied comes with an
optional refrigeration maintenance package that reduces
cost throughout the life of the unit. Compressor isolation
valve and replaceable core lter a dryer reduces pump
down, and service time for providers. Refrigeration
monitoring systems allow quick measurement of the
superheat and subcool performance, low charge
indication, and condenser service status through the
unit controller which saves time on troubleshooting and
service calls.
• Gas Heat Controls: Rebel Applied Gas Heat Units provide
furnace controller alarm feedback to the unit controller
and building automation system so alarms can be
identied quickly to expidite service.
