Chillers - Products
approaches buildings as more than concrete and steel boxes; we see them in terms of the critical comfort needs of the people and the things in the building. More than half of the large buildings in the world today have chiller at their core, playing a critical role in creating the right comfort environment. Not only do our chillers provide the right temperature, humidity and ventilation, they also help reduce your cost of operation, provide energy efficiency and minimize environmental impact. In fact,

The extensive chiller line was developed with decades of know-how and industry leadership and includes centrifugal, rotary and scroll compressor chillers as well as absorption chillers, ranging in nominal capacities from 10 to 3,950 tons.

Absorption Liquid Chillers
Absorption chillers use heat to drive the refrigeration cycle, they produce chilled water while consuming just a small amount of electricity to run the pumps on the unit. Absorption chillers generally use steam or hot water to drive the lithium bromide refrigeration cycle but can also use other heat sources.

Centrifugal Liquid Chillers
centrifugal chillers have a long pedigree. For over 60 years, these products have embodied the global standard of reliability, efficiency and durability. This product continues to be the choice of thousands of engineers and owners worldwide because its reliability and energy efficiency offers lower operating cost over the life of a variety of different types of buildings and applications, from comfort to process cooling. The hermetic design prevents contaminants from affecting the longevity of the machine and virtually eliminates the risk of releasing refrigerants into the environment during normal operations.
centrifugal chillers are among the quietest in the industry. And the exclusive Adaptive Control™ microprocessor can keep chiller operating when others would shut down—often just when you need cooling the most. All of centrifugal chillers feature multiple stages for a large operating envelope and surge resistance, and a flash economizer to save energy. .


Modular Air-Cooled Liquid Chillers
If you are designing a new system or replacing an existing air-cooled condenser, can satisfy virtually any application need. Whether coupled with an industrial compressor, a single zone commercial self-contained unit, compressor chiller or scroll liquid chiller, has the right air-cooled condenser for the job. One example is centrifugal fan air-cooled condensers, available from 3 to 100 tons, which use ambient air to provide efficient year-round refrigerant condensing. factory-assembled compressor-chillers are ideal for comfort or process cooling applications, keeping the chilled water loop indoors without the need for performance-degrading freeze protection.
All of our units are designed for ease of installation and connection, and have proven, reliable controllers to ensure efficient and cost-effective operation..


Helical Rotary Liquid Chillers
helical rotary chillers provide chilled water for both comfort and industrial cooling systems. These air- and water-cooled chillers can reduce your total cost of ownership because they are engineered for lower life cycle costs and reliability through design simplicity.
Helirotor™ compressor technology is direct drive, low speed (3600 rpm), with only two rotating parts, for high reliability and efficiency. Optimized compressor parts profiles are designed specifically for chilled water applications to optimize full- and part-load efficiency. Adaptive Control™ Microprocessor provides greater reliability through a proactive control strategy, safety functions with simple diagnostics and easy interface with Tracer® building automation/energy management using a single twisted pair of wires. Series R™ chillers are the right choice for tight temperature control in virtually any application,


Scroll Air-Cooled Chillers
has state-of-the-art Air-Cooled Scroll liquid chillers for a wide range of comfort and process-cooling applications. These chillers are complete, factory-assembled liquid chillers that offer ease of installation with wiring and microprocessor controllers providing maximum operating efficiency. Our compact chillers install easily and quickly into most building layouts, making them ideal choices for retrofit or new building designs.


Cooling Towers
There are any numbers of companies that make cooling towers, but none of them has more new ideas. cooling towers are engineered to provide optimal cooling with minimum energy usage. And they’re so quiet, we named them for it.
The Series Quiet™ cooling tower not only sets the benchmark for low sound levels, it also sets the benchmark for some of the highest crossflow tonnage densities per box in the industry. The Series Quiet™ cooling towers deliver thermal performance, low maintenance, versatility of options and outstanding value. However, of greater significance, the Series Quiet™ cooling tower is now quieter.

Refrigerant Monitors
The family of refrigerant monitors offers two important benefits: refrigerant conservation and safety. With the decreasing availability of refrigerants, coupled with rising cost, it is important to have a refrigerant monitor in the equipment room to provide early warning of refrigerant loss. As a leak-sensing device, refrigerant monitor constantly measures the amount of specific refrigerants in the surrounding air. This device is capable of initiating alarms, activating building ventilating systems, and interfacing with Building Automation Systems. ASHRAE Standard 15 – 2001 requires refrigerant monitors to be present in all new chiller installations and all chiller retrofits. Refrigerant monitors are also strongly recommended for all existing chiller rooms or refrigerant storage facilities.

two types of refrigerant monitors: RMWE, the most sensitive monitor on the market and ane offers RMWG, the most flexible and dependable monitor on the market.
