Product display cases used in convenience stores and supermarkets require various temperature controls to properly store items. Our solenoid and expansion valves are used for even temperature distribution in control display cases.
Digital thermostats are also used in places where slight temperature changes can affect product quality, such as at flower and wine shops. These thermostats help to keep products at their optimal temperature while in storage.

Vending machines make use of solenoid valves to offer drinks at the perfect temperature, even in the heat of summer. Heat pump equipped vending machines that offer warm beverages in winter use changeover valves, which helps to save energy.

For hygienic reasons, products must be produced with optimal temperature control In food processing plants. Factories requiring highly precise temperature regulation rely on wide variety of devices, including expansion valves, temperature switches, controllers, and pressure switches to support safe operations.

In product storage warehouses, it is essential to store items at appropriate temperatures. For example, large pieces of meat and fish require -40°C for safe storage, and flowers require around 10°C to remain fresh. Our selection of expansion valves, solenoid valves, and regulating valves can be used based on desired storage temperature and warehouse size. Likewise, our lineup of controllers and other devices can also be used to maintain optimal operations based on warehouse conditions.

Trucks used to transport fresh products to factories, retailers, and homes are equipped with refrigeration devices which utilize expansion valves and safety-critical pressure switches. A variety of Saginomiya products can also be found in refrigerated containers used to transport perishable goods around the world.

Temperature-controlled vinyl greenhouses and other controlled environments are what allow people to purchase fresh vegetables, fruits, and flowers year-round. Thermostats and solenoid valves help to maintain the optimal temperature and growing conditions while humidity controls play a vital role in cultivating mushrooms. Fresh mushrooms can be harvested at any time through humidistats and other devices.

To maintain freshness until they are sold at market, fish are caught, flash-frozen, and then transported. Ships have refrigeration equipment onboard for this reason, utilizing expansion valves, temperature controls, and other devices.
