Understanding Capillary Thermostats

Industrial food warming equipment thermostats

A capillary thermostat is a type of temperature control device widely used in industrial applications where precise temperature regulation is required. It consists of a sensing element, a control element, and a capillary tube connecting the two. The sensing element is usually a bulb filled with temperature-sensitive fluid or a bimetallic strip that expands or contracts with temperature changes. The control element consists of a switch that opens or closes the electrical circuit based on the temperature detected by the sensing element.

The Use of Capillary Thermostats in Industrial Food Warming Equipment

  1. Commercial Ovens and Ranges: Capillary thermostats play a vital role in commercial ovens and ranges, ensuring accurate temperature control for baking, roasting, and cooking processes. These thermostats monitor the oven’s internal temperature and activate the heating element or burner as needed to maintain the desired temperature range. Capillary thermostats in ovens are often combined with timers and safety features to prevent overheating and ensure precise cooking times.
  2. Steam Tables and Bain Maries: Steam tables and bain maries are widely used in buffets, cafeterias, and large-scale food service operations to keep prepared food warm before serving. Capillary thermostats are integrated into these appliances to regulate the water temperature and maintain a consistent heat level. By controlling the heating elements or steam generators, the thermostats ensure that food is kept at a safe and appetizing temperature, preventing overcooking or cooling.
  3. Food Holding Cabinets: Capillary thermostats find extensive use in food holding cabinets, which are used to keep cooked food warm until it is ready to be served. These cabinets are commonly employed in restaurants, banquet halls, and catering services. Capillary thermostats monitor the cabinet’s internal temperature and activate the heating system when necessary, preventing food from reaching unsafe temperatures and ensuring it remains at an optimal serving temperature.
  4. Hot Holding Drawers: Hot holding drawers are another type of food warming equipment frequently used in commercial kitchens. Capillary thermostats regulate the temperature inside these drawers, enabling chefs and cooks to store and maintain the warmth of various food items, such as buns, bread, and cooked meats, until they are ready to be served. The thermostats ensure that the drawers stay within the desired temperature range, preserving the quality and flavor of the food.

Bulb & Capillary Thermostats

Original equipment manufacturers worldwide use thermostat switches designed and manufactured by STEMCO, a Division of Senasys. No matter which style or model you choose, all of the capillary thermostat switches operate using the same physics. A fluid is encapsulated in a metal and when the temperature changes the fluid either expands or contracts. This fluid change moves a diaphragm which is in touch with a snap action switch and either opens or closes a circuit.

Ambient Compensation

Our capillary thermostats can be ambient compensated to offset the differential in temperature which keeps our thermostat controls more accurate as it’s environment changes.

Custom Options

Capillary thermostat switches built by Senasys can also be built to customer specifications. This insures you get the exact control you want without paying for features you don’t need.
