Fenwal Brass Thermoswitches

Fenwal ThermoSwitches at Anderson-Bolds

Fenwal has been controlling temperature since the 1930's with their unique and extremely accurate Thermoswitch temperature controller. The Thermoswitch can sense and switch at .1 degree F.  The Thermoswitch is a bi metal switch with the outer shell expanding and contracting which causes the contacts to make and break. The switch probes are made of brass or stainless steel.  The Brass switches have a range of -100F to 400F while the Stainless switches have a range of -100F to 600F.

As of January 1, 2018 the brass switches have been discontinued and leave the Stainless steel switches as the only choices. The accuracy of the stainless steel is the same as the brass. 

Here are the brass switches and their stainless counterparts.

Fenwal Detect-A-Fire switches

Anderson-Bolds stocks and sells Fenwal's fire protection Detect-A-Fires.

DETECT-A-FIRE units by Kidde-Fenwal are the "heart" of many Fire Protection Systems. These highly reliable devices have been a standard of the industry for over 45 years. Many thousands of these units are now in use controlling the release of extinguishants such as clean agents, C02, water, or dry chemicals. In some systems the device is used as an ALARM device, to sense overheat or fire, and alert personnel. In other systems, it is used as a RELEASE device, to sense fire and actuate fire attack systems.

DETECT-A-FIRE units by Fenwal Controls have met with wide acceptance because they are designed with RATE COMPENSATION. This provides a unique advantage over both fixed temperature and rate-of-rise types of detectors because only the DETECT-A-FIRE unit accurately senses the surrounding air temperature regardless of the fire growth rate. At precisely the predetermined danger point, the system is activated. Fixed temperature detectors must be completely heated to alarm temperature and therefore a disastrous lag in time may occur with a fast rate fire. Rate-of-rise devices, on the other hand, are triggered by the rate of increase in ambient temperature and are subject to false alarms caused by harmless, transient thermal gradients such as the rush of warm air from process ovens.

The secret of the unit's sensitivity is in the design (Figure 1). The outer shell is made of a rapidly expanding alloy which closely follows changes in surrounding air temperature. The inner struts are made of a lower expanding alloy. Designed to resist thermal energy absorption and sealed inside the shell, the struts follow temperature changes more slowly. A slow rate fire (Figure 2) will heat the shell and struts together. At the "set point," the unit will trigger, actuating the alarm or releasing the extinguishant. A transient rush of warm air up to 40F/min. may expand the shell, but not enough to trigger the unit. By ignoring transient warm air excursions, the DETECT-A-FIRE unit virtually eliminates false alarms prevalent with rate-of-rise devices. If a fast rate fire (Figure 3) starts, the shell will expand rapidly. The struts will close, actuating the alarm or releasing the agent. The faster the fire rate of growth, the sooner the DETECT-A-FIRE unit will react.

HORIZONTAL DETECT-A-FIRE-UNITS
Horizontal detectors are designed for locations where appearance is a factor. The attractive, functional design lends physical protection of the unit while making it suitable for commercial, industrial, mercantile and public buildings,institutions and ships in non-hazardous locations (those classified as "ordinary" under the National Electric Code). Flush mounted units are designed to fit standard 4" octagonal electrical boxes and surface mounting units are designed to mount directly on ceilings or on 4" electrical junction boxes. Canadian Electrical Codes requires mounting only to an electrical junction box.
Fenwal part numbers include: 27020 27021
Temperature Settings (degrees F): 140 160 190 210 225 275 325
VERTICAL DETECT-A-FIRE-UNITS
Vertical detectors are designed for use in both "ordinary" or "hazardous" locations. For "ordinary" use, they may be mounted to any approved junction box with 7/8" diameter opening by using 1/2-14 NPT mounting nuts. The device may be wired in or out of conduit, depending on local preference and codes.

Temperature Controls - Mechanical

Fenwal controls and Barksdale manufacture mechanical temperature control devices. The switches are bi-metal or liquid filled switches that use expansion and contraction to cause the switching. This type of mechanism can be extremely accurate but lacks in displaying the temperature. In todays computerized/automated world this type of control tends to be used for over temperature control or alarm as opposed to the process control point.

Barksdale manufactures liquid filled switches, both for Hazardous areas and normal areas. The switches can be either local or remote mount. They can sense temperatures up to 600 degrees F.

Local mount type temperature switches are installed in the pipe or vessel. In this type of sensor, the filling fluid surrounds the bellows. A negative temperature change forces the fluid to contract - expanding the bellows to actuate the switch.

Remote bulb and capillary type temperature switches allow the switch enclosure to be placed up to 25 feet from the media. These models use a bulb and capillary sensing device which may be ordered in standard six and 12 foot lengths. Extra lengths up to 25 feet are available. Six and 12 foot sensors can be copper or stainless steel with or without protective spiral-wound armor. The 25 foot lengths are armored stainless steel only.

Barksdale's MT1H & T2H Series Temperature Switches provide unmatched performance, quality & reliability in a mechanical thermostat. The single set point MT1H and dual set point T2H, can switch, measure & control temperatures from -50° to 650°F (-45° to 343°C), The optional adjustable differential provides precise control while ambient compensation maintains 1/2% accuracy with external temperatures from -65° to 165°F. The MT1H & T2H Series are electrically rated for 10 amps @ 125/250 VAC & 3 amps @ 480 VAC. Standard 3- & 6-pin terminal strips simplify installation. The MT1H & T2H Series are rated NEMA 4 & 13; the optional NEMA 4X construction protects the rugged die-cast aluminum enclosure from corrosive environments. A remote bulb and capillary sensor is available in copper or stainless steel allowing the switch to be mounted up to 25 feet from the temperature source. Optional thermowells allow the sensor to work in pressurized vessels to 5000 psi. UL listed & CSA approved, MT1H & T2H Series Temperature Switches are perfect for your temperature sensing needs.

Barksdale's L1X, T1X & T2X Series Temperature Switches provide unmatched performance, quality & reliability in a mechanical thermostat - a safe solution for hazardous locations.

The FENWAL THERMOSWITCH was invented in the 1930's to control fish tanks, irons and other simple applications, but it was soon realied that they could be used for industrial, commercial and process applications. They're durability, reliability and accuracy are the strong points for THERMOSWITCHES.

THERMOSWITCH® Temperature Controllers are tubular devices featuring an outer shell made of high-expanding metal and internal struts made of low-expanding metal, with a pair of electrical contacts between them.

When the temperature of the media being measured changes, a corresponding change in the spacing of the contacts provides instant on/of

f control with a small differential, resulting in +1°F precision, depending upon the application.
