Key features

Evaporator coil - microchannel

• Microchannel coils are 40% smaller, 40% more eff icient, and use 50% less refrigerant than standard tube and fin coils.
• Multiple micro channels improve heat transfer.
• Flat tube results in lesser air side pressure drop, less power consumption.
• Compact design & less also resulting in reduced unit weight.

Electronic expansion valve

• Necessary for integrated and optimal variable capacity control.
• Maintain constant superheat
• EEV is standard feature in PEX3

EC fan

• The unit is equipped with high efficiency, single inlet, reserve curved, centrifugal plug type innovative EC fan(s).
• The EC fan technology regulates airflow and reduces the fan input power. In-floor configuration further reduces energy consumption in downflow units.
• Liebert EC 2.0 fan modulates the fan speed according to load density; saving nearly 30% of energy consumption

Compact design

• PEX3 has a footprint nearly 15~30% lower than other brands, available in 4 frame sizes.

Wide capacity range

• PEX3 DX is available from 30kW up to 100kW both down flow and uplow configurations.

Precise temperature & RH control

• PEX3 technology enables close monitoring and control of room temperature, the standard version includes advanced controller, heater, humidifier and other components.

Environment friendly option

• The use of the eco-friendly refrigerant R410A ( standard) is particularly advantageous. The best parameters in terms of heat exchange to improve greenhouse performance.

The Liebert® PEX is the Next Generation Thermal Management Environmental Control System from Vertiv. It is a result of extensive research and development, conducted with leading environmental control experts, consultants and major corporations. A wide range of standard units offered from 20 KW to 100 KW in Upflow & Downflow Configurations.

Liebert Mini-Mate adalah sistem pendingin ruangan komputer jejak kaki nol untuk kontrol suhu dan kelembaban 7x24 dan penyaringan udara. Produk ini diinstal pada atap dan mudah diservis, hanya membutuhkan akses depan untuk pemeliharaan.

Benefits

Key features

iCOM^TM control

• Several graphic display options

• Integrated Web Communication

• Preventive maintenance through an advanced troubleshooting

• 400 stored events/unit

• Up to 16 stored temperature and humidity days

EC fans

• AC powered 50/60 Hz without frequency converter

• Static pressure continuous adjustment

• Energy consumption 30% lower than AC motors

• No maintenance

• Long life transmission

Heat exchange surface

• High Energy Efficiency Ratio (EER). It basically depends on the heat exchange surface. Refrigerating circuits consume less energy.

• High SensibleHeat Ratio (SHR). Sensible heat vs. latent heat. Technological applications require a high sensible heat discharge, without lowering room humidity too much, as it would need to be restored through a humidifier.

Key features

Modularity - easy to move and quick to install

• Liebert Air Handling Unit (AHU) units are customized to suit dierent room space and transportation.

Highly eicient

• Mechanical PUE less than 1.2 as part of a system
• Use of EC fans for lower motor power usage
• Self-optimizing controls reduce over-cooling and under-cooling
• Uniform airflow and temperature across the supply air side

Greater protection

• Advanced monitoring and event notification
• Finely tuned & advanced controls for more consistent supply air temperature & eliminating hot spots through rack inlet temperature sensor
• Feasible with UPS to back up either to whole system or controller only 

Lower Installation & Maintenance Costs

• Multiple section design minimizes shipping costs and speeds installation
• Less component to maintain and ease of access for better service and maintainence

Insight for action

• Simplified access to realtime data and trending
• Quick diagnostics of potential critical events

Cooling capacity

• Customized design based on dierent cooling load requirement, airflow and other specific customer requirements. It does not require unit knock down on site for transportation, better quality control & less components to maintain and service.

Advanced controls for eiciency, protection and insight

• Liebert Air Handling Units (AHU) are best used with Liebert intelligent controllers, wired or wireless rack sens​ors, and a Liebert central optimizing system control to ensure that the entire data center system is optimized with the other components of the chilled water system. Liebert intelligent control algorithms continuously process readings from the rack inlet sensors to ensure optimal air flow through the system while supply air sensors are used to control the unit cooling capacity.

Benefits

• Equipped with heat exchangers made with oval copper tubes.
• Design improves the heat exchanger capacity versus drycoolers with traditional coil geometries. 

Key features

• Modulating fan speed control with single set point or with double set point for freecooling operation, to switch between summer mode (compressors working) to winter mode (freecooling operation).
• Epoxy-coated coil.
• Hydraulic connections flange kits (for three-phase models, single-phase models are provided with threaded hydraulic connections).
• Can be installed either horizontally or vertically, with simple operations to be done on site.
