Hard-working Chillers, Condensers, and Coolers

We represent manufacturers of centrifugal chillers that offer the highest IPLV energy efficiencies and the lowest lifetime operating costs in their capacity ranges. We also offer adiabatic cooling systems, sophisticated dry air cooling systems, and more eco-friendly coolant circulation systems.

At CESI, our sales engineers consult on building custom systems to handle a range of requirements. No matter which type of custom chiller is required, our team helps clients find efficient options that are easy to operate and maintain over a long lifecycle. Our lines of advanced chillers drive whole-life ownership costs down and save on operating costs, maintenance costs, and reduce mechanical risks.

Aermec was founded in Italy in 1961 and has provided efficient and innovative chiller and commercial HVAC solutions to the North American market since 2007. The company offers a wide variety of air-to-water chillers, free cooling chillers, modular chillers, heat pumps, high-temperature heat pumps, multipurpose heat pumps, and the world’s quietest fan coils.

NIMBUS offers a range of advanced process cooling solutions that address facilities and operations requirements while also reducing water consumption. NIMBUS’ cooling systems save water and energy by introducing water only when necessary. This technology eliminates the need for chemically treated water, costly maintenance programs, and the health risks associated with standing water. Ask about VIRGA hybrid adiabatic coolers, BOREAS dry cooling systems, winery fluid cooling systems, Bluedrive coolant circulation systems, as well as industry-leading controls and filters.

Petra offers a complete line of air-cooled and water-cooled chillers. The state-of-the-art units deliver low sound, reliability, high energy efficiency, and small physical footprints. The wide range of cooling capacities and flexible configurations make them easy to install and maintain. Each chiller is equipped with an intelligent microprocessor controller to manage the unit’s performance for optimum efficiency at both full load and part load values. Petra chillers are designed as a complete factory package, and each passes a 100% test run before shipping.
Smardt chillers are among the top five manufacturers globally and are ranked number one in oil-free high-efficiency in the centrifugal sector. They feature an oil-free Turbocor® compressor that has magnetic bearing technologies and variable speed drives. This Turbocor compressor is the most energy-efficient type of chiller; it reduces energy consumption by 50% compared to traditional compressors. According to, “This ultra-high-speed technology eliminates up to 99% of compressor induced vibrations and dramatically reduces the sound levels emitted by the chiller”
