HVAC Solutions for Commercial, Corporate and Industrial Infrastructure

In these systems, the refrigerant expands and exchanges heat directly inside a coil that is in direct contact with the air to be cooled.

• Mini Splits and Multi Splits: Systems consisting of one outdoor condensing unit and one or more indoor evaporator units, such as wall-mounted, cassette or floor units.
• VRF / VRV Systems: Networks in which a central group of condensing units modulates refrigerant flow independently to dozens of indoor evaporator units.
• Packaged Units (Rooftop / RTU): Self-contained units installed outdoors or on rooftops that deliver conditioned air through a duct network.
• Commercial Split Systems: An outdoor condensing unit connected through copper piping to an indoor air handler or fan coil unit.

These systems use a closed circuit of water or a water-glycol mixture that is cooled in a central plant and distributed through piping to the areas requiring air conditioning.

• Chillers: The heart of the system. They typically cool water to between 4 °C and 7 °C and may be air-cooled or water-cooled, using centrifugal, screw or scroll compressors.
• Air Handling Units (AHU): Large centralized units that receive chilled water in their coils and deliver filtered air through ductwork.
• Fan Coil Units (FCU): Compact terminal units for individual zones or rooms containing a water coil and a fan.
• Cooling Towers: Mechanical-draft equipment that rejects heat from condenser water to the atmosphere in water-cooled chiller plants.
• Chilled Water and Condenser Pumps: Hydronic pumping equipment that maintains constant fluid circulation throughout the piping network.

Designed to control temperature, relative humidity and filtration with high accuracy during 24/7/365 operation in environments where failure is not an option, including Data Centers, operating rooms and laboratories.

• CRAC Units: Precision cooling equipment operating on the direct-expansion principle.
• CRAH Units: Precision air handling equipment supplied with chilled water from external chillers.
• In-Row / In-Rack Coolers: Compact modular units installed between server rack rows to remove high-density thermal loads directly at the source.
• Immersion Cooling Systems: Electronic components or servers are immersed in dielectric fluids with high thermal-transfer capabilities.

These systems lower air temperature by using water evaporation. As water changes from liquid to vapor, it absorbs thermal energy from the air.

• Evaporative Coolers: Also known as air washers or swamp coolers. Outdoor air passes through wet media and is supplied at a lower temperature and higher humidity.
• Adiabatic Dry Coolers: Closed heat exchangers that spray a fine water mist over outdoor coils during hot weather to improve heat-rejection performance.

These systems take advantage of naturally available outdoor thermal resources to provide cooling while reducing or temporarily eliminating mechanical compressor operation.

• Air-Side Economizers: Motorized damper modules installed in AHUs or Rooftop units that introduce outdoor air when its temperature is lower than the indoor temperature.
• Chillers with Free Cooling Modules: Chillers equipped with coils that use outdoor air directly to cool hydronic water during colder seasons without operating the compressors.
• Geothermal Heat Pumps: Systems that use the relatively stable temperature of the ground or groundwater for heat exchange and thermal dissipation through buried circuits.
