Water-Cooled Chillers
Water-Cooled Chillers
Precise, high-power cooling, space-saving by design.
Mydax water-cooled chillers deliver energy-efficient cooling wherever a facilities water source is available — engineered for high cooling power, reliability, and precise temperature control without large air-cooled condensers.

Why water-cooled
Efficient cooling, with the water you have.
When a facilities water source is available, a water-cooled chiller rejects heat to your building water — delivering high cooling power in a compact, energy-efficient package without bulky air-cooled condensers.
Space-saving efficiency
Heat is rejected to facilities water — no large air-cooled condensers required.
High cooling power
Up to 70 kW of cooling capacity for the most demanding loads.
Wide, precise range
From −85°C to +150°C with patented proportional control for smooth regulation.
Built for precision-critical work
Semiconductor & defense, cooled to spec.
Where temperature stability is non-negotiable, Mydax water-cooled chillers deliver clean, precise, high-power cooling for the most sensitive systems.
