Liebert SRC-G 3kW Cooling System Overview

Precision Cooling for Small Critical Technology Rooms

Liebert SRC-G 3kW Cooling System is designed to manage the predominantly sensible heat produced by UPS systems, batteries, servers, communication equipment, automation systems and other critical electronic loads.

Model SRC03GES provides 3000W nominal total cooling and 2700W net sensible cooling under the specified rating conditions. Its sensible heat ratio above 0.9 enables the unit to focus cooling capacity on equipment-generated dry heat.

The indoor unit delivers a nominal airflow of 934.5 CMH. A high-efficiency EC fan adjusts airflow according to operating conditions while supporting efficient continuous cooling.

The wall-mounted indoor unit preserves valuable floor space inside compact equipment rooms. The separate outdoor condensing unit rejects heat outside the protected technological environment.

A hydrophilic-coated copper-tube and aluminium-fin cooling coil provides a large heat-transfer surface. The outdoor condenser also uses a hydrophilic-coated coil designed for demanding ambient conditions.

The advanced controller provides temperature management, operating-status information, alarm generation, automatic restart after power recovery and sequencing of up to eight compatible units.

Remote monitoring and access control help operators supervise cooling conditions and restrict unauthorised changes to system settings.

Liebert SRC-G 3kW Cooling System Features

High-Sensible Cooling with Intelligent Control

The SRC03GES combines efficient airflow, precision temperature management and remote supervision for small mission-critical rooms.

High Sensible Heat Ratio

An SHR above 0.9 directs cooling capacity toward the dry heat generated by electronic equipment.

High-Efficiency EC Fan

The EC fan provides stepless speed modulation and high airflow with efficient electrical operation.

Multi-Unit Sequencing

The controller can sequence up to eight compatible cooling units for coordinated room operation.

Automatic Power Recovery

Automatic restart functionality restores cooling operation following the return of electrical power.

Equipment-Room Filtration

A washable G4 filtration system helps reduce dust and airborne contamination inside the cooling environment.

Remote Monitoring

Compatible communication enables remote operating visibility, alarm supervision and cooling-system monitoring.
