Liebert (not to be confused with Lieberton) belongs to the Emerson Network Power division of Emerson Corporation. The main activity of the company: development, production and sale of air conditioning systems, power supply equipment (uninterruptible power supplies, diesel generator sets, batteries, etc.). The structural division, which arose after the acquisition of Hiross, is engaged in the production of Liebert Hiross precision air conditioners only.
The company often offers integrated solutions for heat removal and power supply systems. Requirements for the equipment so that it works non-stop full day all year round and ensures the accuracy of maintaining the microclimate, in particular temperatures up to a degree. This may require a point heat removal (from server equipment, power supplies, communication stations, etc.).
The devices can be attributed to the budget line.
Air Conditioning Systems Emerson Liebert
The equipment is divided into external, internal units and universal units. The function of external units is to cool the coolant into the external environment. Indoor units - heat removal from the room or equipment. Universal - perform both functions at the same time. Cooling can be air or water.
Equipment series:
- Liebert HPW. Monoblock to be installed on an external wall. Designed to cool containers with telecommunications equipment. Cooling capacity from 5.3 kW to 14.9 kW;
- Hiline Slim. Direct mechanical cooling unit. Installed directly on the object that needs to be cooled (telecommunication rack, servers, etc.);
- Liebert HPF. Cabinet-type floor-standing monoblock for indoor installation. Cooling capacity from 4.9 kW to 16.3 kW;
- Cabinet Cooler. Direct cooling air conditioner. Cooling capacity from 3.86 kW to 5.74 kW;
- Liebert HPM. Cabinet, air conditioner. Condenser cooling can be air or water. Some models provide for smooth regulation of cooling capacity, a two-circuit cooling circuit from different independent circuits;
- Liebert HPA. External condensers to remove heat from indoor units;
- Liebert HPD. Water cooled dry coolers;
- Liebert HPC. Air cooled chillers. Within the series, there are several lines, denoting different designs of blocks. A wide range of cooling capacities from 322 kW to 1529 kW. Possibility of cascade assembly;
- Liebert HPC-S. A series of chillers with a lower cooling capacity from 40 kW to 350 kW;
- Liebert HPC-R. Chillers with centrifugal fans, produced by the parent company, cooling capacity from 40 to 350 kW;
- Liebert HPC-W. Indoor water cooled chillers. Power from 280 kW to 1200 kW;
- Fan coil units - FCV, FCY, FCC, FCX. Two-pipe and four-pipe with various installation methods;
- Duct fan coil units - FHC.2-pipe and 4-pipe, combinations of different methods of installation and connection to cooling blocks;
- XD. For rooms with high heat dissipation. The third letter means different execution schemes. O - suspended ceiling unit, V - for cabinet roof mounting, H - floor installation between equipment racks, P - pump unit, C - chiller, A - fan unit. The combination of units can provide up to a maximum of 30 kW of heat removal from one object.

Liebert Console and Air Conditioning Instructions
The equipment manual (including the manual for Libert Hiross air conditioners, the installation of the air conditioner, error codes, etc.) is in many ways unique, since such systems are usually created for a specific order and the whole complex is developed and functions as a whole.
Equipment control is usually intelligent and built into the overall system of the whole complex functioning. Or / and various remote controls for the air conditioner can be installed. It displays both informational parameters, and various operating modes can be turned on and off (which circuit to cool, fan speed, etc.).
The system is a reliable protector against unwanted changes in the microclimatic parameters of the room. To increase reliability, two or more redundant circuits with dependent or independent control are involved in it.
Liebert air conditioner error codes
The self-diagnosis system of such devices is rather complicated. A description of the error codes is given in the instructions for a specific device implementation scheme. Although they are typical in many ways, it is not recommended to use similar descriptions from similar devices in order to avoid damage to expensive equipment. Moreover, it is emphasized in the annotations that the manufacturer reserves the right to make changes to the equipment that do not worsen its declared characteristics.
Changes can be included in the regulations of the supplied equipment.
User reviews
Reviews of precision systems emerson liber hiros on the forums are moderate. This equipment occupies a budgetary price niche in its class. In this regard, users and service personnel often note minor breakdowns (breakage of plastic holders, bypass valves, etc.). One of the advantages is fast, high-quality, timely repair organized by official distributors in Russia.
Although, in general, the installations are of high quality, which will cool the equipment for a long time. And the existing minor flaws are paid off at a significantly lower cost compared to a number of leading brands in this industry.
