POWERS CONTROLS

About POWERS CONTROLS

Powers Controls is a manufacturer of pneumatic and electronic control components for commercial HVAC and industrial systems. The brand's product line includes pneumatic thermostats, damper actuators, static pressure probes, and retrofit kits, with a focus on reliable, serviceable components for building automation. Powers Controls products are commonly found in older pneumatic control systems, and the brand maintains compatibility with legacy designs while offering modern replacements. 3G Electric supplies the Powers Controls line to plant engineers, maintenance managers, and procurement specialists worldwide, providing access to individual SKUs and logistics support for global delivery.

The product families available through 3G Electric cover several key areas of HVAC control. Single-temperature remote-bulb sensor thermostats, such as the 40PN38 and 40PN39, are liquid-filled bulb pneumatic devices with a control range of 60° to 85°F, two-pipe high-volume air flow output, and direct or reverse action. These thermostats include a 96-inch capillary for remote sensing. Retrofit kits, like the 40PN29, are designed to replace Robertshaw pneumatic thermostats in commercial HVAC systems, featuring direct action and vertical mounting with a beige cover. Static pressure probes, such as the 40PN30, have a 7 1/4-inch exterior length and 4 1/2-inch insertion length, with a push-on process connection and mounting flange for duct static pressure measurement. Linear actuators, including the 40PN46, 2KGP4, 2KGP5, and 40PN48, are pneumatic damper actuators with extended shaft or pivot mounting, rubber construction, and spring ranges of 3 psi to 13 psi or 8 psi to 13 psi. Some models are specifically designed for fire and smoke damper applications. These actuators do not include a positioner and use clevis or pivot connections.

Powers Controls components are built to standard pneumatic control specifications, with materials and construction suited for HVAC environments. The thermostats and actuators operate on low-pressure air, typically 3 psi to 13 psi or 8 psi to 13 psi, and are compatible with common pneumatic control systems. The static pressure probes are constructed for duct mounting and include a mounting flange for secure installation. 3G Electric supports the Powers Controls line by stocking multiple SKUs and offering logistics support for global shipping. Technical buyers can source individual components for maintenance, repair, or retrofit projects, with access to product specifications and manufacturer part numbers for verification. The availability of retrofit kits and direct replacements helps extend the life of existing pneumatic control systems without requiring full system replacement.
