Cast metal gears provide higher shear strength and greater resistance to heat-related warping

The Johnson Controls A28AA-29 is a heavy-duty two-stage temperature control designed for precise cycling of multiple HVACR components

Whether you are servicing an 80% AFUE furnace or a comparable gas-fired unit

This single-stage gas valve operates on a standard 24V HVAC control circuit and is factory-calibrated for a 3

this high limit control switch features an automatic reset mechanism calibrated to interrupt the electrical circuit if temperatures exceed the 180°F threshold

Warrick DFB1A0 Level Control Refrigerant Cast metal gears provide higherThe Warrick DFB1A0 is a high performance 120V dual level control designed for demanding industrial and commercial HVACR applications. This solid state liquid level controller utilizes conductivity based sensing to manage two independent functions: a single level control and a differential level operation. This makes it an essential component for low water cutoff (LWCO) systems and pump up pump down sequences in boilers and food service equipment. With
