Air containment solutions separate cold airflow supply from the hot equipment exhaust air in the data center. This simple separation creates a uniform, controllable, and predictable supply temperature to the intake of IT equipment which translate to increased up-times and longer hardware life.

• Increase data center performance for IT equipment
• Provide uniform, controllable, and predictable inlet air temperatures
• Reduce or eliminate hot spots
• Augment Airflow Management and Water Loop Management solutions by allowing fan/pump speeds to more effectively match output with load requirements
• Support several energy-reducing adjustments including temperature and RH set points, lower fan speeds, and an increased chilled water / glycol setpoint

• Improved cooling performance
• Reduced compressor run time
• Uniform and predictable air temperature at the IT intake
• Financial savings
• Energy savings
• Reliability
• Often eligible for utility rebates (administered by EE)

Replacing forward curve fans in CRAC/CRAH units with electronically commutated (EC) fans will help to regain fan performance that has degraded over time, enable variable speed control in response to load conditions, and improve energy efficiency.

• Add life to legacy air conditioning units, including units that are 20 to 40 years old. Retrofitting existing CRAC/CRAHs eliminates the need to buy costly new replacement units and can extend the life span of the CRAC/CRAH up to 7 more years.
• Augment Airflow Management by adjusting fan speeds to more effectively match airflow output with load requirements. This prevents overcooling.
• Operate more air conditioning units at slower speeds, instead of simply turning off units. This generates significant energy savings, usually with very good paybacks.
• Provide redundancy via 2 or 3 fan motors, instead of one.

• Improved cooling performance
• Extend equipment life
• Financial & Energy savings
• No maintenance costs
• Reliability and Redundancy

Lighting systems typically consume approximately 5% of the electricity used by a data center. While this is a small percentage, lighting efficiency can still help data center owners save on energy costs. Retrofitting fluorescent lighting with LED technology will enhance lighting quality and aesthetics, reduce O&M, and provide energy savings.

• Enhance lighting quality in the working environment
• Modernize legacy data centers
• Reduce lighting maintenance needs
• Provide occupancy controls where applicable
• Reduce energy consumption for lighting and cooling systems

• Increase worker safety and productivity
• Financial savings
• Energy savings
• Reliability

Variable frequency drives (VFD) are applied to existing fan and/or pump motors to enable variable speed control in response to load conditions. VFDs are a cost-effective way to modify existing computer room air handling or water pumping systems and realize significant improvements in performance and energy efficiency.

• Augment Airflow Management by adjusting fan speeds to more effectively match airflow output with load requirements. This prevents overcooling.
• Augment Water Loop Management by adjusting pump speeds to more effectively match flow output with load requirements. This prevents overcooling.
• Operate more air conditioning units or pumps at slower speeds, instead of simply turning off units (see chart). This generates significant energy savings, usually with very good paybacks.

• Improved cooling performance
• Financial savings
• Energy savings
• Reliability and longer equipment life

A Controls Tune-Up is a service to analyze and tune the existing control systems that overlay the mechanical and electrical HVAC equipment in the data center (temperature, pressure, and flow control systems for air and water) to optimize performance.

• Unstable temperature control or temperature swing
• Thermostats and sensors that are out of calibration
• Competing control algorithms
• Controls sequences that are functioning incorrectly
• Improper setpoints
• Simultaneously heating and cooling
• Older equipment in need of upgrades

• Improved cooling performance
• Financial savings​
• Energy savings
• Lower maintenance costs
• Ability to monitor CRACs through remote user interfaces
• Reliability and longer equipment life
• Redundancy
• Often eligible for utility rebates (administered by EE)

Water Loop Management is a systematic process to optimize refrigeration circuits and the distribution of chilled water to air handling equipment to improve performance in the data center.

• Low temperature differential across CRAC/CRAH cooling coils
• Chilled water or condenser water temperatures that are too low or too high
• Refrigerant temperatures and pressures that are too low or too high
• Pumps that operate at unnecessarily high speeds or that operate at a constant speed even though the load being served is variable
• Valves that are not functioning properly
• Chiller and cooling tower performance issues (air and water sides)
• Water flow that is less than optimal
• Older equipment in need of upgrades

• Improved cooling performance
• Financial savings
• Energy savings
• Lower maintenance costs
• Reliability and longer equipment life
• Redundancy
