The company specializes in the manufacture of specific climate equipment - chillers of various designs, precision air conditioners Stulz. The latter are intended for precise control of temperature and humidity conditions in the premises. Scope: server rooms, rooms with telecommunication equipment. Stulz is a responsible manufacturer with innovative technology. Separately, it is necessary to note the quality of products.
The main line of air conditioners and products
Climatic installations of this type are designed for year-round room maintenance. Specificity - low error rate not exceeding 1 ° C from the set temperature. To optimize the work, there is a winter mode - intake and further preparation of cold air from the street. Stuls models are distinguished by technical parameters, design and service rules.
The company has not yet developed a full-fledged Russian-language website, information on its products is partially posted with a few representatives. There you can find basic prices, photo models, get minimal information about the specifics of the work. Consider the main lines that the manufacturer currently offers.
Mini space ec
This series air conditioner is designed for installation in small and medium rooms. Suggested cooling options: air, water-glycol mixture or water. You can select the direction of air flow - descending or ascending. Each precision air conditioner is equipped with a modern EU 4 class filtration system.
Basic technical parameters:
- cooling power varies from 12.1 to 31.7 kW;
- heated humidifier installed;
- high-temperature refrigerant R134A is used;
- installed fans with DC motors.
The use of EC technology has a positive effect on the economical consumption of electricity. The efficiency of the equipment will increase - up to 92%.
The system responds to changes in the thermal conductivity of indoor air. Based on information from the sensors, temperature and humidity are regulated.
Cyberrow
A feature of the equipment in this series is in-line conditioning. The device takes the heated air from the working passage in the room, processes and directs the flow further. The functional purpose of the system is filtration and cooling. You can order the installation of an additional module for drainage.
It is important to know the features of work that Stulz precision air conditioners have, the manual describes in detail the following points:
- cooling power - from 24 to 56 kW;
- installation between equipment cabinets is recommended;
- you can block one of the air outlet openings to concentrate the flow in a certain area;
- line connection, duplication of the work of blocks.
A high-precision module is designed to adjust the temperature regime on a certain area. Additionally, the layout of the serviced equipment is taken into account.
Important - the manufacturer gives restrictions on the microclimatic parameters of the premises served. The set of equipment is not mounted in rooms with an aggressive environment, strong magnetic or thermal radiation.
Split systems Split-Air
This split system of the company differs from standard analogues. It is designed for zonal cooling of air in work rooms where installation of floor units is impossible or difficult.Advantages - optimization of work due to intake of cold air from the street, small size of the indoor unit.
Main characteristics:
- cooling power - from 3.8 to 11.1 kW;
- two zones of airflow distribution - horizontal and vertical;
- effective air purification system;
- ceiling installation of air conditioning possible.
The advantage is integration with the floor models of the manufacturer. This will optimize the operation of the entire complex, concentrate the direction of flow in a specific volume of the room.
Features of Stulz products - air conditioning can be provided by local staff after training. Installation and repair work must be entrusted to company representatives.
Comparison of the characteristics of popular models
Before buying this climate equipment, you need to make calculations of all parameters: the required temperature, humidity indicators, the distribution of air flows in the room. Based on this, the optimal complex for servicing server or similar purpose rooms is selected.
You also need to consider the basic characteristics of the equipment, which are contained in the instructions:
- installation type - floor, wall or ceiling;
- rated power;
- cooling method - water, air or water-glycol;
- degree of air purification.
Comparative characteristics of the three popular models are shown in the table.
| Model | CCD 181a | CRS 251a | SCD 271a |
| Cooling power | 18,1 | 25,3 | 27,3 |
| Air consumption | 4300 | 5400 | 8300 |
| Power consumption | 5,2 | 6,8 | 7,3 |
| Humidifier performance | 3 | 4 | 5 |
| Heating stages | 2 | 2 | 3 |
| Dimensions | 870*1880*770 | 1950*400*1175 | 1400*1980*8300 |
| Weight | 72 | 250 | 410 |
The price is formed individually, depending on the configuration of the system. Additionally, you need to consider the cost of maintenance, the cost of energy and coolant.
Instructions for the control panel and air conditioners Stulz
Instructions for air conditioners were developed for each type of climatic equipment. It describes the features of maintenance and repair of complexes. The manufacturer recommends that staff receive training to learn basic skills in working with equipment. This is due to the individual work of each model.
The classic remote for the air conditioner has been replaced with the adaptive user interface C-7000. Its features:
- informative LCD screen;
- the ability to connect to well-known service systems;
- communication systems support SNMP / HTTP IP protocols;
- the ability to customize individual parameters.
The advantage of this control system is the connection of several air conditioning units to organize collaboration. For the full functioning of a large complex, installation of temperature and humidity sensors in various parts of the room is needed.
Error codes for air conditioners Stulz
Comprehensive control of the cooling system is carried out automatically. The equipment is designed for continuous operation, many blocks are duplicated. But this does not exclude the appearance of malfunctions or breakdowns. When they occur, the system issues error codes. Their list and classification are individual for each model and depend on the configuration.
To minimize the appearance of malfunctions, the manufacturer recommends adhering to the following rules:
- timely service climatic equipment;
- comply with the rules of operation;
- continuous operation in maximum cooling mode can lead to rapid wear;
- control of coolant level, degree of air filter pollution.
Important - independent repair without prior consultation with company representatives may lead to deterioration of equipment condition.
User reviews
Equipment of this class does not apply to general purpose systems. Therefore, reviews about the work of models are rare, mainly the specifics of the work are discussed in relevant forums. Based on the analysis of this information, conclusions can be drawn about the quality of the functioning of the models.
Benefits:
- maximum autonomy of work;
- extensive interface customization options;
- combining several models into a common cooling system.
The only drawback is the high cost. But given the purpose and specifics of the work, the price is acceptable. It is important to choose the right package, for which you need professional engineering calculations.
