Chillers
Chillers produce chilled water that is circulated to air handling units, fan coils or process equipment throughout a building or plant, making them the backbone of large-scale cooling where a single central plant is more practical than many separate refrigerant systems. Frosten supplies and installs air-cooled and water-cooled chillers for large commercial buildings, data centres, hospitals and industrial process cooling.

Frequently Asked Questions
Should I choose air-cooled or water-cooled?
Air-cooled chillers are simpler to install and need no cooling tower, suiting most commercial buildings up to a few hundred tonnes. Water-cooled chillers are more efficient at larger capacities but need a cooling tower, condenser water treatment and more plant room space; we assess this trade-off during design.
Do chillers need a dedicated plant room?
Water-cooled systems generally need a plant room for the chiller and pumps, with the cooling tower outside. Air-cooled chillers can often sit on a rooftop or ground-level pad without an enclosed plant room.
How is chiller capacity sized?
Sizing is based on a full building cooling load calculation — floor area alone is not sufficient at this scale — accounting for glazing, occupancy, equipment heat gain and climate data.
