744 Series - Accritem® Rigid and Remote Bulb Controllers

Accritem controllers are used to maintain temperature in a variety of applications, including water heaters, compressors, coolers, heat exchangers, and more. The controllers are offered with either rigid or remote bulb sensing elements, which are mounted directly in the medium to be controlled. When a temperature change occurs, Accritem responds with a pneumatic signal sent to a control valve.

Accritem Rigid Bulb Controllers

Rigid bulb controllers include pressure gauges and a 1/2" NPT pipe fitting. The sensing element is available in either copper or stainless steel.

Available rigid bulb controllers:

Air operated, direct action rigid copper bulb
Air operated, reverse action, rigid copper bulb
Water operated, direct action, rigid copper bulb
Water operated, reverse action, rigid copper bulb
Air operated, direct action, rigid stainless steel bulb
Air operated, reverse action, rigid stainless steel bulb

Accritem Remote Bulb Controllers

Remote bulb controllers enable increased flexibility with remote monitoring of temperatures. They are offered in either copper or stainless steel and include a 3/8" NPT brass compression fitting to allow direct mounting of the bulb in a pipe or tank in a variety of positions.

Available remote bulb controllers:

Air operated, direct action, remote copper bulb
Air operated, reverse action, remote copper bulb
Air operated, direct action, remote stainless steel bulb
Air operated, reverse action, remote stainless steel bulb

595 Series - #11 Self-Operating Temperature Regulators

Powers offers numerous remote bulb options to provide flexibility to fit your applications. Powers #11 regulators negate the need for external power to control the process of the heating or cooling medium while maintaining a consistent temperature. They are applicable to a wide range of uses including processing equipment, heat exchangers, and machinery.

Component System Thermal System Options

Powers provides flexiblity and economy with its #11 Regulator line of interchangeable sensing and control components. The line offers a selection of 29 thermal systems (remote bulb, capillary, and bellows) and up to 35 standard valve assemblies to meet a variety of specialty process needs. With these regulators, you can quickly replace the valve assembly in your supply line as your needs change or if a thermal system becomes damaged.

Available Component System Thermal System Options:

#11 Type ST Regulators for heating or cooling
#11 Type CD Regulator for heating
#11 Type DS and DB Double Seat Regulators for high capacity heating or cooling
#11 Type WM Water Mix Regulators for water mixing

In addition to the wide range of options available in the above component thermal system regulators, Powers Process Controls also offers the ability to customize #11 Regulators for specialty applications. For more information about all of the options available with these regulators, see the #11 Self-Operating Temperature Regulators Datasheet and contact us to start your order.
