Product Introduction

This large water-cooled package combines two independent refrigerant circuits around hermetic twin-screw compression. At approximately 1407 kW, the 400-ton-class chassis offers greater capacity and circuit separation for a clean production campus than the single-circuit smaller frames.

Key Features

Dual-circuit resilience

Separate refrigeration paths allow staged operation and retain partial cooling if one circuit is unavailable.

Large screw-compressor duty

The compressor and heat-exchanger package serves central process loads at the 400-ton scale.

Standard pressure framework

The referenced 150 psig water-side rating provides a basis for plant hydraulic selection.

Technical Parameters

Nominal Capacity	400 tons / approximately 1407 kW
Refrigerant Circuits	2 independent circuits
Compressor	Hermetic twin screw
Water-Side Pressure Rating	150 psig standard
Evaporator	Large chilled-water heat exchanger
Condenser	Water-cooled heat exchanger
Capacity Control	Circuit staging and screw modulation
Resilience	Partial capacity available by circuit arrangement
Installation	Heavy indoor central-plant base
Customization	Circuit controls, pressure rating and water interfaces can be configured for the intended application and operating environment.

Applications

Large pharmaceutical and semiconductor campuses, high-capacity clean manufacturing and central process utility plants requiring staged cooling.

Solutions for Your Application

A single refrigeration circuit creates a large loss of capacity during service.Use the dual independent circuits within a plant-level resilience and maintenance plan.

The high-capacity machine may exceed standard water pressure or electrical assumptions.Verify the 150 psig standard rating, final pump head and electrical selection against the complete plant design.

Available Options

Higher water-side pressure rating, starter arrangement, heat recovery, isolation, metering, sound treatment and plant-control communication can be selected.
