Economizers - (49 companies)Economizers are mechanical devices that are designed to reduce energy consumption, or to perform other useful, energy-related functions (such as preheating fluids). Economizers are mechanical devices that are designed to reduce energy consumption... -
Boilers (industrial) - (596 companies)Industrial boilers are closed vessels that use a fuel source or electricity to heat water or generate steam for industrial heating and humidification applications. -
Damper Actuators - (51 companies)Damper actuators are powered devices that are used to operate a damper and adjust the flow of air and smoke. -
Carburetors - (24 companies)Carburetors are devices used to proportionally mix a fuel with air for a combustion process. -
Dampers and Louvers - (301 companies)Dampers and louvers are used to control the flow of air in a process system or enclosed area. Dampers are usually motorized or manually-adjustable for flow control. Louvers are often fixed for a constant flow rate. -
Heat Pumps - (284 companies)Heat pumps are reverse cycle air conditioners. They use a compression cycle system to supply heat or remove heat from a temperature-controlled space.
-
Toilets - (117 companies)Toilets are a plumbing fixture that are used for disposal of human waste. A variety of toilets are manufactured, and are implemented based upon existing infrastructure and cultural attitudes.
-
Thermal Switches and Thermal Protectors - (625 companies)Thermostats and thermal switches are electro-mechanical on/off switches that are activated by temperature changes. They are typically used to control heating and cooling systems.
-
Water Softeners - (217 companies)Water softeners remove the hard calcium and magnesium minerals from water.
-
Scrubbers - (386 companies)Air scrubbers, wet scrubbers, and gas scrubbers are air pollution control devices that use a high-energy liquid spray to remove aerosol and gaseous pollutants from an air stream. The gases are removed either by absorption or chemical reaction.

Schaltbau GmbH
Schaltbau introduces the R300 high-voltage relay and significantly reducing the risk of contact welding. The double contact bridge design provides improved arc extinguishing performance. With a making capacity of up to 200 A, the relay is engineered for long-term durability even under tough operating conditions. An integrated economizer circuit keeps pull-in power consumption below 12 W, enabling direct control with a programmable logic controller (PLC), lowering operating costs and thermal stress while extending service life. "Reliable isolation... (read more)Browse High Voltage Relays Datasheets for Schaltbau GmbH -
Schaltbau GmbH
Eddicy’s new megawatt charging contactor portfolio . With separate contact systems for switching and current carrying, the series stands out for its exceptional longevity. Furthermore, silver alloy contact pills result in a contact resistance as low as 35 uOhm, ensuring best-in-class performance with low contact warming. An integrated economizer ensures optimal pull-in performance during switch-on and minimizes energy consumption in holding mode. As a result, the megawatt charging contactor series reduces power losses in the system, delivering up to 25%... (read more)Browse Electrical Contactors Datasheets for Schaltbau GmbH

For over 20 years the generic method of maintaining the prescribed amount of outdoor ventilation air has been through the use of a supply-return fan tracking system. The latest draft of ASHRAE Standard 62-1989R requires "controls and devices to maintain outdoor air flow within 10% of required...
The economizer portion of an air-handling system is not only responsible for reducing the operating cost of the system, but more importantly, it has to provide a sufficient volume of outside air at all times to ensure good indoor air quality. The function of the economizer also affects...
An averaging temperature sensor (ATS) is generally used to maintain the design mixed air temperature of an airside economizer system. These devices can have sensing elements from 5 to 50 feet long and generally provide acceptable performance if they are installed properly so they not only sense...
...environment conditions, PUE, and economizer mode hours. The choice of hot-aisle containment over cold-aisle containment can save 43% in annual cooling system energy cost, corresponding to a 15% reduction in annualized PUE. This paper examines both methodologies and highlights the reasons why...
