Commercial food service equipment is found in restaurant canteen kitchens and stand alone for profit dining establishments (hotels, hospitals, educational/work place facilities, airports, stadiums, army barracks, etc). Typically, these facilities are subject to public health laws. They are inspected periodically by public-health officials, and forced to close if they do not meet hygienic requirements mandated by law. The fast food and convenience food trends have also changed the way restaurant kitchens operate. There's a trend for restaurants to only "finish" delivered convenience food or even just re-heat completely prepared meals, maybe at the utmost grilling, a hamburger, or a steak.
Common equipment found in most commercial establishments include Commercial Refrigerators, Commercial Freezers, Walk In Coolers, Refrigerated Prep Tables, Commercial ice machines [Cube, Flake, Storage, Undercounter machines/makers], Commercial ranges [charbroilers and hot plates included], Dishwashers, Ovens, Fryers, Warming & Holding Cabinets, Combi Ovens, Steamers and Steam tables. Counter top cooking would include – Panini Makers, Toasters, Griddles, Salamander Broilers, Waffle Makers, Convection Ovens, Fryers, and Hot Plates. Specialized Equipments would include – Concession equipment, Bakery equipment, tilting skillets/braising pans, BBQ equipment, Ice Cream Equipment, Pasta Cookers, Asian Cooking Equipment, Tandoori Ovens, Hot Dog Cookers, and Coffee Making Equipment.
PUI has manufactured sensors used in every area of the commercial food service equipment. Some of the most challenging applications that we have achieved success:
Refers to the various tools and equipment used by scientists working in a lab. The equipment is generally used to perform an experiment, take measurements, and gather data. Our goal is to be in any instrument that the measurement is temperature dependent located in a R&D, clinical, medical, environmental, or industrial lab. We are also capable of making sensors for both the Automating processes market and the scientific instrumentation industry – which is best known for their ability to measure temperature with a high degree of accuracy and precision.

Types of equipment:
Biomass boilers - Low temperature hot water biomass boilers, those operating at up to 95 °C, can be classified by various methods based on fuel type or on the physical characteristics of the boilers. The classification that follows is based on fuel type. The critical difference between stoves and boilers is that stoves provide radiant room heating while boilers only produce hot water, either for heating or domestic hot water (DHW). Although some stoves will allow the incorporation of a boiler and radiators, stoves are usually much simpler devices than boilers. Many temperature sensors are used in biomass furnaces. They have to be insensitive to dirt, mechanical load and big temperature fluctuations; but on the other hand they have to be cheap. Hence a compromise concerning a fast and accurate measurement is accepted.
Manufacturers and wind farm operators require high quality environmental measurements to maximize performance and fulfill industry standards. These needs with weather sensors for control systems, wind speed and direction monitoring, weather condition monitoring directly on the turbines, and visibility sensors that dim obstruction lights in clear weather to improve community acceptance of wind farms. The motors in the turbine that generate the electric also need sensors to monitor bearings and motor temperatures.
The Ethanol Sensor measures the concentration of gaseous ethanol, from which the concentration of ethanol in a solution may be inferred. The sensor’s probe contains a material whose resistance decreases in the presence of ethanol. The sensor translates this resistance into an ethanol concentration measurement, which is recorded and displayed by the connected computer or datalogger. The Ethanol Sensor is well-suited for continuous recording and discrete measurements.
Boilers – high efficiency – defined - Boilers from a few decades ago usually ran at about 68 to 72 percent efficiency, meaning about 30 percent of the energy consumed by a boiler went to waste. Today, high-efficiency boilers operate at 90 to 97 percent efficiency. Mid-efficiency boilers, which cost about half as much as their mid-efficiency counterparts, operate around 80 percent efficiency. Higher efficiency comes courtesy of a handful of technological improvements. Old boilers relied on a pilot light, a hefty heat exchanger that consumed more energy, and natural drafts to push heat. Today, mid-efficiency boilers use an electric ignition that turns on when the system is turned on, have smaller parts that consume less energy, and push heat using a precise exhaust fan. High-efficiency boilers take those advances a step further, featuring a sealed combustion chamber and a second heat exchanger that condenses gas to further reduce energy use.
Manufactures polymer materials and offers services in plastics important to a range of industries, including aerospace, building and construction, electronics, packaging, and transportation. Common equipment are injection molding machines, polymer processing equipment, heating/cooling equipment for injection molding machines.
Automation - is the use of machines, control systems and information technologies to optimize productivity in the production of goods and delivery of services. PUI’s line of ENET™ sensors are designed to custom fit into automation control systems. With its linear output they work well with PLC’s.
