Introduction de produit

The 250-ton machine increases compressor capacity, condenser coil length and fan count beyond the compact 115-ton chassis. It provides central chilled water for medium-to-large clean manufacturing buildings while retaining outdoor air-cooled heat rejection.

Key Features

Mid-range central capacity

The 250-ton platform serves a larger process or building loop without moving to the longest 500-ton frame.

Increased condenser surface

Additional coil modules and fans reject the greater compressor heat load at outdoor design conditions.

Adaptive operating control

The integrated controller coordinates compressor and fan stages around leaving-water and equipment limits.

Applications

Central cooling for medium-to-large pharmaceutical buildings, electronics production, controlled manufacturing and healthcare support plants.

Solutions for Your Application

A 115-ton unit lacks capacity, while two independent small machines increase piping and control complexity.Use the 250-ton platform where the verified load and resilience plan favor one mid-range chassis.

More condenser modules require unobstructed outdoor airflow.Maintain manufacturer-based side and overhead clearances and prevent hot discharge-air recirculation.

Options disponibles

Sound reduction, low-ambient controls, evaporator pump package, coil coating, heat-trace, flow measurement and network integration are available.
