Our product portfolio: Your new savings potential
A large number of server rooms offer the potential to significantly reduce energy consumption. With the right cooling concept, a data center is designed for energy and cost efficiency already in the planning phase.
Our experts use performance measurements to determine your current energy requirements and determine the required performance spectrum of your cooling needs.
With an optimally designed energy-efficient cooling solution, several 100€ to several 100,000€ per year can be saved in electricity costs, and thus CO², depending on the size of the system. We stand for this annual savings potential with our name and give you a money-back guarantee in case of non-performance.
Security through availability
Data centers must have the highest availability day and night. Air conditioning is one of the highest power consumers.
Modern precision cooling systems, for example with energy-efficient indirect free cooling and adiabatic cooling, ensure availability and save up to 40% energy.
ONI offers solutions for server rooms, small data centers/data centers as well as large and modular data centers/data centers in the power range between 1KW and 150 MW.
ONI has over 35 years of experience
We‘re also using our years of experience in plant construction of refrigeration and air conditioning technology for complex IT cooling processes.
ONI also offers individual solutions from a single source in this field. Highest reliability and low operating costs have the highest priority.
The systems combines state-of-the-art technology, such as Inverter technology, EC fans, frequency control, free cooling and heat recovery systems with intelligent control.
Refrigeration-as-a-Service / Rental refrigeration
A further component of our 24/7 service is that we support our customers quickly with cooling on demand.
Our mobile refrigeration units are assembled and commissioned on site at the customer's premises in the shortest possible time.
With our rental machines, we can serve a range of capacities from machines with a few kW up to aggregates with several MW of capacity.
Highly efficient ONI plant technology
The highly efficient ONI plant technology with huge CO2 saving rates as well as the useage of modern natural refrigerants is rewarded by high state subsidies for new investments as well as for renovations of existing refrigeration plants.
We are also happy to advise you on subsidies in the field of DC cooling.
