CONDITION &
DISTRIBUTE
AirPak air handling units receive chilled water from the central plant, heat or cool it, filter it, and deliver precisely tempered air throughout the facility via ductwork. Variable Air Volume (VAV) systems modulate airflow dynamically based on real-time zone demand — delivering energy savings without sacrificing comfort.
Chilled Water VAV Capable Multi-Zone Title 24 Compliant
Best For

Large multi-zone facilities requiring independent environmental control in each space. Pairs seamlessly with the ChillCore central plant.

CHILLED WATER
ChillCore chillers produce chilled water that is simultaneously distributed to all building air handlers. Purpose-built for large, multi-zone commercial and industrial facilities — more efficient, more controllable, and more scalable than standalone packaged units at higher load levels.

⚠ Lead Time Note

ChillCore 300 carries a 26-week lead time. Plan procurement early — mechanical rough-in typically occurs well before substantial completion.

REJECT HEAT.
PROTECT EFFICIENCY.
TowerCell cooling towers reject heat from the chilled water system to the atmosphere. Required for water-cooled chiller plants. An undersized or poorly maintained tower will degrade chiller efficiency significantly — matching tower capacity precisely to chiller output is essential for peak performance and energy compliance.
Water-Cooled System Chiller-Matched Sizing Efficiency-Critical
Best For

Any facility running a water-cooled ChillCore plant. TowerCell models are paired to specific chiller capacity ranges — always specify together.
