Chemical-free cooling that outperforms traditional absorption and mechanical systems.
Advanced yet simple—proven to excel in price, reliability, and performance.
Mazda’s dual-/triple-/quad-ejector-based chillers remove dissolved air for efficient, compact cooling.
Ideal for chemical, pharmaceutical, food, and paper industries where reliability and footprint matter.
Product Overview
The Chiller Vactor System utilizes multiple steam jet ejectors, integrated chill tanks, and advanced controls to deliver high-performance evaporative cooling. Unlike conventional systems, it features automatic deaeration—removing nearly all dissolved air and gases to significantly reduce corrosion risks. Compact and efficient, this system requires minimal installation space and operates maintenance-free, making it an ideal solution for industries requiring consistent chilled water output with operational simplicity and low lifecycle costs.
The system employs a series of multi-nozzle steam jet ejectors (typically two to four) arranged in staged configuration. High-pressure steam creates suction to draw water through internal chill tanks. The automatic deaeration process removes gases, and the resulting chilled water is circulated for cooling. Controls optimize steam usage by adjusting for cold water and condenser flow, while its compact, modular design allows for easy installation even in tight spaces.

A Chiller Vactor is a steam jet ejector-based cooling system that uses multiple ejectors, chill tanks, automatic deaeration, and controls to produce chilled water. It provides compact and reliable evaporative cooling without conventional mechanical refrigeration.
High-pressure steam passes through the steam jet ejectors and creates suction that draws water through the internal chill tanks. This staged ejector arrangement enables evaporative cooling and produces chilled water for circulation through the cooling system.
Automatic deaeration removes dissolved air and gases from the water during operation. This helps reduce corrosion risks and supports more reliable operation of the chilled water system.
Dissolved air and gases can contribute to corrosion within cooling systems. The Chiller Vactor's automatic deaeration process removes nearly all dissolved air and gases, helping reduce corrosion-related risks.
The system uses steam jet ejectors rather than conventional mechanical refrigeration equipment. Steam creates the required suction and cooling effect through staged evaporative cooling, eliminating the need for hazardous refrigerants.
Yes. The Chiller Vactor is designed to handle wide load variations and operate efficiently under off-design conditions, including higher inlet or ambient temperatures. Its controls adjust operation to optimize steam, cold-water, and condenser flow.
Multiple steam jet ejectors can be arranged in a staged configuration to support the cooling process efficiently. Mazda's Chiller Vactor typically uses two to four ejectors, providing flexibility for different cooling requirements.
Yes. Mazda Limited's Chiller Vactor can cool liquids to 0 °C, and freezing can also be achieved where permitted. The chilled-water operating range is approximately 1.67 °C to 2.11 °C.
Chiller Vactor systems are suited to industries where reliable chilled-water output and compact installation are important, including chemical, pharmaceutical, food, and paper industries.
The system has a compact and modular design that requires minimal installation space. Its configuration allows it to be installed even where available plant space is limited, while still providing chilled water for process cooling.
