Aerospace Defense – PAO Chillers

Problem

An aerospace and defense contractor faced challenges with maintaining optimal fluid temperatures in a critical military aircraft program. The Poly-Alpha-Olefin (PAO) fluid loops, essential for system performance, required precise cooling at a setpoint of 59°F with a tight stability range of +0/-10°F, even under demanding conditions like ambient temperatures up to 125°F. Excessive fluid temperatures threatened operational reliability, necessitating a robust solution capable of consistent cooling across an operating range of -40°F to +120°F and varying altitudes.

Solution

Chillermen, specializing in custom chiller design and manufacturing, was engaged to address the issue. Chillermen developed a pair of tailored air-cooled chillers engineered to provide precise PAO fluid cooling, ensuring stable temperatures and pressures vital to the aircraft’s performance.
