Compressor Test Bench Automotive A/C Compressor Test Benches and Calorimeters are designed in accordance with ASHRAE Standard 23 and ISO Standard 917 for compressor development and endurance testing. Calorimeter systems are designed to provide heat balances within ±2% with a repeatability of ±1%. The Test Stands are designed for continuous duty over long time periods to allow endurance testing of compressors under extreme conditions. We offer a standard line of automotive compressor test benches and calorimeters up to 17 ton capacities. Climatic Testing Systems Climatic Testing Systems, Inc. (CTS) is a single-source supplier of complete line of Compressor Test Benches. Our line of Compressor Test Systems includes Compressor Endurance Test Stands, Compressor Calorimeters, QA Audit Benches and Compressor Clutch Test Benches. CTS Compressor Test Benches provide as a standard, control of all critical parameters as compressor speed, discharge pressure, liquid temperature or sub-cooling, suction temperature or superheat, and suction pressure. In addition, CTS, offers automatic real-time oil flow control that allows the user to precisely and accurately control and report the percentage of oil in circulation. The Compressor Test bench offers a unitized design which incorporates compressor and drive assembly, compressor fixture plate, condenser and associated water cooling circuit, Coriolis type flow meter (Micro motion Elite) and either a secondary refrigerant evaporator or an evaporator with glycol loading circuit. These Compressor Test Stands are complemented by Innovative and high-performance Real-Time software. CTS Compressor Test Software is based on open-architecture and data-critical platform. It connects multiple sources of event-driven data in real-time and seamlessly ties complex test algorithms.

Climatic Testing Systems
Climatic Testing Systems, Inc. (CTS) is a single-source supplier of complete line of Compressor Test Benches. Our line of Compressor Test Systems includes Compressor Endurance Test Stands, Compressor Calorimeters, QA Audit Benches and Compressor Clutch Test Benches.
CTS Compressor Test Benches provide as a standard, control of all critical parameters as compressor speed, discharge pressure, liquid temperature or sub-cooling, suction temperature or superheat, and suction pressure. In addition, CTS, offers automatic real-time oil fl ow control that allows the user to precisely and accurately control and report the percentage of oil in circulation.
The Compressor Test bench offers a unitized design which incorporates compressor and drive assembly, compressor fi xture plate, condenser and associated water cooling circuit, Coriolis type fl ow meter (Micro motion Elite) and either a secondary refrigerant evaporator or an evaporator with glycol loading circuit.
These Compressor Test Stands are complemented by Innovative and high-performance Real-Time software. CTS Compressor Test Software is based on open-architecture and data-critical platform. It connects multiple sources of event-driven data in real-time and seamlessly ties complex test algorithms.
