Liebert (not to be confused with Lieberton) is owned by Emerson's Emerson Network Power division. The main activity of the company: the development, production and sale of air conditioning systems, equipment for power supply (uninterruptible power supplies, diesel generator sets, batteries, etc.). The structural division that emerged after the incorporation of Hiross is engaged in the production of only Liebert Hiross precision air conditioners.
The company often offers comprehensive solutions for heat removal and energy supply systems. Requirements for the equipment to work non-stop for a full day all year round and ensure the accuracy of maintaining the microclimate, in particular temperature to a degree. In this case, a point heat removal may be required (from server equipment, power supplies, communication stations, etc.).
Devices can be attributed to the budget line.
Air conditioning systems Emerson Liebert
Emerson Liebert air conditioners are a product line of various industrial cooling systems. The main place in it is occupied by high-precision, precision equipment. The company is in no way associated with the company producing domestic air conditioners Liberton with a consonant name. Liberton is a Chinese household air conditioner.
The equipment is divided into external, internal blocks and universal blocks. The function of the external units is to cool the coolant into the external environment. Indoor units - heat removal from a room or equipment. Universal - perform both functions simultaneously. Cooling can be air or water.
Equipment Series:
- Liebert HPW. Monoblock mounted 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. It is installed directly on the object that needs to be cooled (telecommunications rack, servers, etc.);
- Liebert HPF. Floor-mounted candy bar cabinet type for indoor installation. Cooling capacity from 4.9 kW to 16.3 kW;
- Cabinet Cooler. Air conditioning direct cooling. Cooling capacity from 3.86 kW to 5.74 kW;
HPS Split. Split system consisting of an internal and external unit. Available in two versions of cassette and wall type. Cooling capacity from 6.1 kW to 14.7 kW;- Liebert HPM. Cupboard, air conditioning. Condenser cooling can be air or water. Some models provide for smooth adjustment of cooling capacity, a dual-circuit cooling scheme from different independent circuits;
- Liebert HPA. External capacitors for removing heat from internal units;
- Liebert HPD. Drycoolers water cooling;
- Liebert HPC. Air-cooled chillers. Inside the series there are several rulers indicating different execution of blocks. A wide range of cooling capacity from 322 kW to 1529 kW. Possibility of cascade assembly;
- Liebert HPC-S. A series of chillers with lower cooling capacity from 40 kW to 350 kW;
- Liebert HPC-R. Chillers with centrifugal fans, manufactured by the parent company, cooling capacity from 40 to 350 kW;
- Liebert HPC-W. Water-cooled indoor chillers. Power from 280 kW to 1200 kW;
- Fancoils - FCV, FCY, FCC, FCX. Two-pipe and four-pipe with various installation methods;
- Channel Fan Coils - FHC. 2 and 4 pipes, combinations of various installation and connection methods to cooling units;
- Xd. For rooms with high heat density.The third letter means various patterns of execution. O - suspended ceiling unit, V - for installation on the roof of the cabinet, H - floor installation between racks with equipment, P - pump unit, C - chiller, A - fan unit. The combination of blocks can provide a maximum of 30 kW of heat dissipation from one object.

Instructions for the Liebert control panel and air conditioners
The equipment manual (including the instructions for air conditioners Libert Hyross, installation of an air conditioner, error codes, etc.) is largely unique, since such systems are usually created for a specific order and the entire complex is developed and functions as a whole.
Equipment management is usually intelligent and integrated into the overall functioning system of the entire complex. And / or various remote controls for air conditioning can be installed. It displays both information parameters and various operating modes (which circuit to cool, fan rotation speed, etc.) can be switched on and off.
The system is a reliable fuse 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.
Error codes for Liebert air conditioners
The self-diagnosis system of such devices is quite complicated. Error codes are described in the instructions for the specific device implementation diagram. Although they are in many respects typical, however, in order to avoid damage to expensive equipment, it is not recommended to use similar descriptions from similar devices. Moreover, the annotations emphasize that the manufacturer reserves the right to make changes to the equipment that do not impair its claimed characteristics.
Changes may include 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 budget 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 a quick, high-quality, timely repair, organized by official distributors in Russia.
Although the overall installation is of high quality, which will cool the equipment for a long time. And the existing minor flaws pay off at a significantly lower cost compared to a number of leading brands in this industry.
