Data Center
Full data center service from design to operation – from one source – from H1 Systems.
Conventional and prefabicated / Containerized datacenters
The custom-built data center is the conventional way of constructing a data center where modularity and flexibility are not among the expressed priority demands buta rather physical security and adaptation to build environment are much more emphasized.
The custom-built data center is the conventional way of constructing a data center where modularity and flexibility are not among the expressed priority demands but a rather physical security and adaptation to build environment are much more emphasized.
The professional challenges in the construction of a built data center are in the specific features of design, implementation and operation. With the support of its experienced professionals H1 Systems provides customized solution in each and every case.
The biggest difference compared to the conventional data center is in modularity. The pre-fabricated data center solutions provide our client the following option among other:
- fast and sound quality implementation
- optimal capacity and cost allocation
- scalable expansion
Pre-fabrication can mean several solutions from masonry modules (modular) to turnkey containers.
Before pre-fabrication we do an intensive and precise assessment and planning process where all questions get clarified due to the experience of decades of our personnel. Thanks to the standardized and quality assured conditions of component manufacturing, assembly, set-up and testing, you can significantly reduce the number of unexpected challenges during on-site installation which usually involve additional time-wasting and costs.

Cooling
Cooling is the most dynamically developing field of data center infrastructures. Nowadays, beside the conventional direct expansion (DX) systems you can also find data centers with even indirect evaporation or adiabatic free cooling systems.
The chosen cooling solution significantly influence the operation costs of the data center, consequentially, development activities focus on improving energy efficiency and reducing operation costs. This way of thinking is reflected in our designing objectives, implementation commitment and operation precision. In Hungary you can meet the indoor thermal requirements by using free cooling in the 90-95% of uptime. By choosing a good cooling solution, 10-45% of cooling energy can be saved (compared to a conventional solution) in accordance with customer demand, local endowments and environmental conditions.
We offer a broad range of manufacturing solutions in cooling, as well:
Vertiv (previously Emerson Network Power) - EFC solution
Vertiv - AFC solution
Vertiv - Econophase
Rittal - liquid cooling solution
Huawei - Eco cooling
As an initial step of meeting energy efficiency and environmental or increased demand, the condition of existing technical devices and processes must be evaluated. H1 Systems offers professional support to realize these in a close cooperation with the professionals of the customer. In case of a modernization, identification of errors, energy optimization or efficiency improvement, it is a usual advantage if an engineer auditor or developer (external) colleague is also involved in the process.
Our highlighted products are the followings:
- Econophase , namely free cooling with DX system
- Adiabatic cooling (water pre-cooling)
- Compact free cooling liquid cooling system
According to the ASHRAE 2011 guidelines for data centers, the evaporation technology will be one of the most efficient ways of cooling in case of data centers. We are able to cool the air to 25-26oC for ICT devices with minimal evaporation (by using 2-4m3/h 1 MW cooling). For this there are two ways:
- direct (Eco-cooling)
- indirect free cooling (Vertiv EFC solution) where indoor and outdoor air are separated
Compressor cooling and free cooling
Compressor-based cooling is the simpliest way of data center cooling service. By using smart regulation, we improve energy efficience in the case of new or already existing systems.
Possible solutions:
- automated set point manually fine-tuned liquid cooling’s set point
- smart group regulation of the free cooling chiller
- new compressor technologies
Rack layout and cooling
- CRAC – Computer Room Air Conditioning
- warm-cold aisle
- inline cooling

Our exceptional technology solutions:
Absorption cooling
In case of the heta resource/waste heat is available, absorption cooling is an efficient way of supplying cooling water of the data center. The combination of gas engine (fuel cell) with absorption cooling can be a benefitial solution, as long as gas prices are low.
Direct liquid cooling

General engineering
At the construction of a data center, beside the specified architectural design you have to build up and syncronize several mechanical, low and high voltage power systems in an outstandingly reliable quality.
H1 Systems provides full building-up of systems, HVAC design and implementation. Air handling is the key of HVAC systems. Good ways for it are smart air ventilation or proper humidification.
Power supply, UPS, Diesel
One of the most important components of data centers is power supply. With its precise and professional preparation and design we support our partners from concept making through full implementation to efficient operation and maintenance.
At a full power supply system, it is indispensable to harmonize the distribution network, the uninterrupted power supply (UPS) devices and auxiliary operation systems (aggregators) as a single system and provide:
- appropriate redundancy level
- availability
- meeting international standards and regulations: Uptime Institute, ISO, TIA
UPS Solutions:
Conventional solution:
double conversion + battery + diesel generator set
- Several redundant configuration

EM and RF protection
For the protection of data centers and the information stored there, the followings has a highlighted importance:
• protection against electromagnetic radiation (electrosmog)
• protection against wire-tapping
• protection against data robbery
• identification of possible risks
• creation of multi-level protection.
At our EM and RF protection solutions we consider:
- data center environment, local conditions
- structure of supply systems, their environmental impact
- quality level and classification of stored information
The creation of protection is always a multi-disciplinary complex task which can spread from the lower to higher level of shading of the rooms (EMC and EMP protection, even with a TEMPEST qualification.
Fire protection
In the server areas also exists the possibility of a fire hazard. H1 System protects the machines, the building and the environment. We perform several tasks in the fire protection market segment. Rely on our expertise.
Automatic fire extinguisher - and sprinkler systems
In order to provide high level availability for a facility, the fire protection has a highlighted importance. This are not exclusively requirements regarding life protection since most of the times devices got damaged not by fire but the combustion flue gases which go in the device’s parts and cause damages and can result in operation break.
