The Quick Start feature - designed
for your critical applications
Temperature sensitive operations such as data centers,
pharmaceutical labs, hospitals, semiconductor production
and other manufacturing facilities require constant cooling
for equipment and processes. If power fails and cooling is
interrupted, critical operations may also fail – risking millions
of dollars in equipment failure and operational downtime.
The Quick Start feature reduces the risk of
cooling disruption
Standard on all YMC² magnetic bearing centrifugal chillers, the
Quick Start feature saves both time and money by:
• Reducing time for chiller restart after a power failure
• Rapidly bringing the chiller back to pre-power
failure operating capacity
• Keeping critical space and equipment cooled
• Reducing the risk of expensive downtime
Smarter Power Management, Faster Restarts
After power is interrupted, it can take a standard centrifugal
chiller many minutes to restart. But YMC² chillers can restart
within 45 seconds after power is restored from a 15 second
or shorter power failure. During a power failure, the Magnetic
Bearing Controller, OptiView™ Panel, and OptiSpeed™
variable speed drive control circuits remain energized until the
facility’s emergency generator is activated. This smart power
management eliminates the need for a control panel reboot so
that the chiller can restart within 45 seconds of power being
restored.

The fastest capacity recovery in the
industry
Not only will your YMC² chiller restart quickly, more
importantly, your chiller will return to its original
operating conditions quickly, ensuring your facility
does not lose precious products or services. YMC²
chillers can get back to pre-power failure operating
capacity within 3 minutes and 30 seconds.*
The YMC² YORK centrifugal chiller offers significantly
faster capacity recovery times compared to the
industry’s typical centrifugal chiller. For your critical
cooling application, consider a YMC² chiller that can
return your facility to 100% capacity faster than any
other chiller.
There are several factors that can alter or improve the
times of a chiller with the Quick Start feature:
• Specific chiller configuration
• Percent capacity operation prior to power failure
• Length of the power failure
A performance test can be requested to witness
restart times and capacity recovery times for your
specific chiller, capacity operation, and length of power
failure. Performance tests, requested in advance, are
held at the Johnson Controls Water-Cooled Chiller
Performance Test Facility and Customer Center in
San Antonio, TX alongside our Water-Cooled Chiller
Manufacturing Facility.
Proven Performance
With an ever-growing number of centrifugal chillers with Quick Start installed around the world, you receive peace of mind
knowing your chillers – and your operation – can be protected by Johnson Controls from the consequences of a power failure.
