Description

FIELD OF TECHNOLOGY

The present disclosure relates generally to laboratory, industry, commercial and home devices, and more specifically, to precision temperature control devices that can be used to circulate heat transfer fluids.

BACKGROUND

Heating circulators, also called “bath circulators”, “refrigerated and heating circulators” or “chillers” are used in lab and industry applications for temperature control of various apparatus and materials, and also for heat removal purposes. Bath circulators have been used in labs and industrial operations since the early 1950s. One of the functions of a bath circulator is to control the temperature of a bath. Some systems have heating and cooling capabilities and are designed to very precisely regulate temperatures with 0.01° C. precision. Circulator systems can control temperatures ranging from −80° C. to +400° C.

DETAILED DESCRIPTION

Various embodiments of the disclosure are discussed in detail below. While specific implementations are discussed, it should be understood that this is done for illustration purposes only. A person skilled in the relevant art will recognize that other components and configurations may be used without departing from the scope of the disclosure.

Several definitions that apply throughout this document will now be presented. “Heating Circulator” may also refer to devices that both heat and cool. “Circulating” means agitating, pumping, blending or mixing of one or more fluids. Hence a “circulator” is a device which can be configured to agitate, pump blend or mix a fluid. Fluids will be understood to comprise liquids. “Coupled” means connected, whether directly or indirectly through intervening components and is not necessarily limited to physical connections. Devices which are in signal communication with one another are coupled. “Connected” means directly connected or indirectly connected, and includes, but is not limited to physical or mechanical connections.

Broadly speaking, this disclosure relates to a laboratory heating circulator for laboratory and industrial temperature control use. However, home and commercial uses are also contemplated within this disclosure.

In at least one embodiment, a heating circulator has a motion sensor designed to detect movement to turn on the circulator information display to show temperature info/system status if users are near. Utilizing a motion sensor to modulate the amount of time a display is activated can extend the operational life of a circulator. Utilizing a motion sensor to automatically show information can reduce the need for users to touch and damage the circulator, thereby extending the operational life of the circulator, especially when touching the circulator increases the likelihood that the circulator will be contacted by hazardous or corrosive materials.

In at least one embodiment, the heating circulator has a multi-function hose connector located on the fluid ejection outlet/inlet that can allow for multiple and different types or styles of hose/tube connection interfaces without using adapters.

In at least embodiment a heating circulator has cooker includes a Wi-Fi™/Blue Tooth™ radio to allow users to monitor status and control the system remotely.

In at least one embodiment of this disclosure, a heating circulator can include a liquid crystal display (LCD) and LCD interface elements such as LCD graphics and text can changes color dynamically based on the temperature of the bath or apparatus. For instance the background changes blue for subzero temperatures or change to red if the temperature is above 100° C.

In another embodiment, the heating circulator can sync (or couple) wirelessly or through cabling to allow one heating circulator to control other heating circulator systems or one PC to control multiple systems.

In another embodiment, the heating circulator can utilize a non-contact wireless infrared temperature thermometer to allow the system to take remote temperature readings of apparatus that is being temperature controlled by the heating circulator.

In another embodiment, the heating circulator can be configured to record and calculate total heat released by a particular apparatus and track the heat release over time to determine an end point of reactions or an end point of other industrial processes.
