The AIRSYS 36.9kW OPTIMA-INV DXA-DFC Precision Cooling System is designed specifically for use within small, medium and large data centres, as well as for process and cleanroom applications. OPTIMA units combine precise temperature and humidity control with outstanding reliability.
OPTIMA INV-DXA is a DX air-cooled system, optimised to deliver energy efficient solutions utilising EC fan and inverter compressor technology as standard. With options to combine DX-based cooling with Airsys leading edge direct free-cooling technology, allowing you to exploit low ambient conditions and maximise your energy savings.
OPTIMA-INV DXA Precision Cooling Features
- Precise Control: The control accuracy for temperature is Ò1¯ C and for relative humidity is Ò5%.
- Various Supply Air Arrangements: Supply air arrangements include top discharge (upflow) and bottom discharge (downflow). Return air arrangements include top return, bottom return, front return and rear return, to meet all site requirements.
- Corrosion-Proof: The unit framework is provided with a corrosion protection treatment. The treatment is sufficient to provide protection for a 15year life cycle for inland installation. If necessary, the treatment for sea air environment can be supplied as an option.
- Easy Maintenance: The technical compartment housing the compressor, humidifier, control and safety devices is separated from the air flow, enabling ordinary service and preventative maintenance to occur during operation.
- EC Fan: Highly efficient EC fans are supplied with OPTIMA products.
- Air Filter: A washable, easily maintainable and durable G4 class air filter is a standard configuration for the OPTIMA range. With optional air pressure switch, a clogged filter alarm can be triggered when the filter is dirty.
- Scroll Compressor: OPTIMA (DXA & DXW ) units are equipped with scroll compressors which produce less vibration, lower noise and greater efficiencies.
- Isolated Control Panel: All the electrical and control components are installed in an isolated control panel with orderly wiring and clear labelling, meeting the IEC standards.
- Forced Dehumidification Process: The dehumidification process occurs through decreasing the evaporator coil surface temperature or reducing the air flow across the coil. Variable-capacity systems come with power monitoring tools that are displayed locally, in addition to being available via remote access. Power monitoring can be used to measure efficiencies across systems, regions and networks. This feature can be used for predictive maintenance.
- Self Diagnosis: All the microprocessor-connected components are continuously monitored and controlled and, in case of malfunction, the unit is shut down and the fault is shown on the display.
- Electrode Humidifier (optional): An electrode humidifier, controlled by a microprocessor, monitors and adjusts the humidifying capacity precisely, while the water quality monitoring and wash extends the maintenance interval, prolonging the working life of the unit.
- Electric Heater (optional): The construction of the electric heater element (stainless steel pipe with wrapped fins) allows for a reduced operating temperature, therefore eliminating ionisation, and avoiding unpleasant odours.
Airsys OPTIMA-INV DXA Precision Cooling systems have a cooling capacity from 5.6kW-104.6kW.
