7.5 HP Sterlco Water TCU - 150 PSI - 1985 G-Series - Ready for High-Flow

Sterlco 7.5 HP High-Flow Water Temperature Controller | Model G2712-JX

The Sterlco G2712-JX is an industrial-grade water temperature control unit (TCU) engineered for high-demand thermal management applications. Unlike standard 2 HP or 3 HP units, this "G-Series" workhorse features a powerful 7.5 HP centrifugal pump, specifically designed to maintain turbulent flow and superior heat transfer in large molds, rolls, or jacketed vessels.

This 1985 unit (S/N 35B0189) is a 480V powerhouse, built with the durability that defined Sterlco’s classic era. With a maximum pressure rating of 150 PSI and a specialized "Sterl-Seal" pump design, the G2712-JX is ideal for heavy-duty injection molding, extrusion, or any process requiring high-volume fluid circulation and precise PID temperature control.

Key Features

• High-Flow Performance: The 7.5 HP motor provides the necessary head pressure to overcome resistance in large or complex cooling circuits, ensuring uniform temperatures across the entire process.
• G-Series "Fluidized" Pump: Features a close-coupled design that isolates the motor from fluid contact, drastically reducing the risk of seal-leak damage and extending motor life.
• Rugged 1980s Build Quality: Constructed with heavy-gauge internal piping and a robust electrical cabinet, these units are known for outlasting newer, lighter-duty alternatives.
• Safety & Reliability: Includes standard high-temperature safety cutouts and motor branch circuit protection for 24/7 industrial operation.
• Compact Footprint: Despite its high horsepower, the unit maintains a manageable footprint for easy integration alongside production machinery.
