Precision A/C ApplicationsStulz-ATS is dedicated to the manufacturing of supplemental and precision air conditioning prod-ucts. With an extensive installation base, SATS has earned a solid reputation as a quality supplier and leader in its field.

CeilAiR ceiling mounted air conditioning units provide temperature and/or humidity control for those hot spot areas in the building which exceed the central system capacity. They are an economical solu-tion to such demands which may, in fact, be temporary until the next offices are carved out of an existing plant area, another laboratory added to a school or new medical equipment installed at a hospital. No floor space is required by the CeilAiR ceiling mounted units. The units are designed with a wide range of options to handle both comfort and precision cooling applica-tions. Typical applications include:

Dual Compressor Systems with C-Tech-10 Microprocessor (see Note-1)

Note-1: Dual compressor systems incorporating C-Tech-10 controls pro-vide 2(two) compressor stages of Cooling and 2(two) compressor stages of Dehumidification. The A-Tech-1.2 and A-Tech-20 controls provide 2(two) compressor stages of Cooling and 1(one) compressor stage of Dehu-midification. Therefore, electrical data for dual compressor systems with dehumidification mode (reheat) is controller dependent as shown above.

Dual Compressor Systems with C-Tech-10 Microprocessor (see Note-1)

Note-1: Dual compressor systems incorporating C-Tech-10 controls pro-vide 2(two) compressor stages of Cooling and 2(two) compressor stages of Dehumidification. The A-Tech-1.2 and A-Tech-20 controls provide 2(two) compressor stages of Cooling and 1(one) compressor stage of Dehu-midification. Therefore, electrical data for dual compressor systems with dehumidification mode (reheat) is controller dependent as shown above.
