Ranco A22-392 Cold Control 48 in Capillary

Pneumatic Thermostat With 48 in Capillary

The Ranco A22-392 is a pneumatic thermostat designed for temperature regulation in compatible plumbing and HVAC systems. It features a 48 inch capillary tube that provides flexibility for remote sensing applications. The unit includes mounting brackets for secure installation on slotted or flatted shafts. This new component suits technicians maintaining pneumatic control loops.

Bundled Mounting Brackets For Secure Fit

Supplied mounting brackets allow direct attachment to slotted or flatted shafts without separate hardware sourcing. This inclusion simplifies the parts list for service calls and reduces the chance of mismatched fasteners. The transparent housing lets operators verify mechanism movement during commissioning. No additional software or electronic accessories are part of this mechanical assembly.

Straightforward Mechanical Installation

Installation involves mounting the control body using the included brackets and routing the 48 in capillary to the sensing point. Care must be taken to avoid sharp bends or kinks in the capillary tube that could restrict pressure transmission. The pneumatic design requires no electrical wiring, but system pressure calibration is necessary after fitting. Installers without pneumatic control experience may misroute the capillary or skip calibration checks.

Not Suitable For Electronic

Buyers needing electronic temperature management, programmable schedules, or integration with building automation networks cannot use this pneumatic device. It lacks electrical contacts, communication protocols, and digital readouts. Systems requiring capillary lengths other than 48 in or different pressure ranges are also incompatible.
