DX, chilled water and adiabatic cooling
We select the cooling approach around the site, load profile and resilience requirement. Options include direct expansion, chilled water and adiabatic systems.
4ON CRITICAL INFRASTRUCTURE
HVAC Installation
Cooling for critical equipment must be designed around heat load, airflow, resilience and efficiency. 4ON installs systems ranging from compact room cooling to large multi megawatt technical environments.
Fresh air hybrid systems
Air handling and control systems can automatically vary the fresh and recirculated air mix to take advantage of suitable outdoor conditions and reduce energy use.
Aisle containment
Separating hot and cold air streams prevents mixing, improves cooling effectiveness and helps equipment operate in a more stable environment.
Large and small installations
Our work covers small technical rooms through to complex projects with cooling duties measured in megawatts.
Leading equipment manufacturers
We work with established brands including Stulz, Airedale, Emerson, Daikin, Toshiba and Mitsubishi.
Maintenance and F gas support
Preventative and predictive maintenance can be added after installation, including refrigerant checks and the records required for compliant operation.
Emergency cooling
Portable cooling equipment can be provided when permanent systems are overloaded, unavailable or undergoing repair.
