The Hotwatt Square and Rectangular Cartridge Heater is designed to distribute maximum heat within a desired area. Because they are completely enclosed, square units will furnish more usable heat for a given wattage than a comparable strip heater attached to the exterior of a mod, platen, or other equipment.
The units are inserted in a milled slot, permitting greater lengths than would be feasible with a drilled or reamed hole. Close dimensional tolerances are held to permit intimate fit for best heat transfer to surrounding medium.
Heating elements arranged just beneath outside surface for maximum heat transfer, minimum wire temperature, and faster heating.
Maximum surface temperatures up to 1200°F. Designations are etched on the sheath to preserve accurate shape.
Long, trouble free service.
Made in U.S.A.
Construction:
-Sealed end.
-Mica.
-Series 300 stainless steel sheath for non-oxidizing, stable service in cavities machined for them.
-Element wire situated in close proximity to outside surface for maximum heat transfer, minimum wire temperature, and faster heating.
-Magnesium oxide packing.
-Ceramic element support.
-Teflon insulated leads: 1/4" square.
Fiberglass insulated leads: 3/8" to 1/2" square, 1/4" x 5/8" and 1/4" x 1" rectangular.

SILICONE heater mats consist of heating wire or an etched heating foil, which is encapsulated and insulated between two silicone mats strengthened by textile glass fibers. They are suitable especially for applications requiring precise temperature and homogeneous heat distribution. Due to their low thermal mass they distinguish by quick response and an excellent controllability. Their low mass and small construction height make them interesting for many aerospace applications. Their resistance against moisture and humidity (IP 54 and higher) recommends them for laboratory equipment, catering appliances and frost or condensation protection especially of electronic components. The only restriction of this versatile heater: its max. continuous operating temperature of 200° C (up to 230° C for short periods).
Fitting for your application, silicone heater mats can be build in nearly every dimension and geometry with numerous extra-components, e. g. thermocouples, limiters and thermal fuses.
Especially for larger quantities we recommend to use heating mats with etched heating foil. In regard to forms, dimensions and complexity of heat distribution they are as variable as heaters with heating wire. Through shorter distances and larger surface of etched strip conductors they reach an even higher watt density and a more homogeneous heat distribution.

Alper S.R.L is a leading Company in the development and production of flexible electrical resistors called PTF (Polymer Thick Film).
Thanks to the use of special conductive inks or pastes printed on polyester sheet, ALPER is in a position to produce resistors in many shapes and very reduced thicknesses (generally 0.2 mm) to suit the specifications of the end product.
The inks, that have been developed by our Company, in some particular conditions may show PTC features (Positive Temperature Coefficient); this means that they are able to limit the heat produced, with no need to apply a thermostat and with no risk of overheating.
This type of resistor offers many advantages when compared with the more traditional electrical resistors now on the market.
The particular features of PTF heaters make them so versatile that they can be employed in a wide range of applications in both the domestic and industrial sector.

Higher Watt Density and Temperatures
Watt Flex heaters produce up to 50% higher warrantable watt-densities than conventional heaters and can operate at much higher temperatures - up to
1900 degF (1030 degC).
The Watt-Flex Cartridge Heater is a high-quality tubular heating element bent back on itself and swaged into a cylindrical format. Dalton manufactures heaters using only high-purity magnesium oxide, nickel chromium resistance wire and stainless steel terminals.
Special filling methods and equipment compact the magnesium oxide inside and around the resistor coil to extreme density. Swaging further compacts the magnesium oxide to virtually maximum density, which yields high dielectric strength and efficient internal heat conduction. Unlike conventional heaters, Watt-Flex cartridge heaters have no ceramic core that can crack during swaging.
The continuous coil and tightly compacted MgO assure highest watt-density and higher operating temperatures.
Watt-Flex Cartridge Heaters run more efficiently, use less power, last longer and are much simpler and faster to replace than conventional cartridge heaters.

Infra-red radiation partly reflects with a fall on material and partly absorbs. Tre absorbed radiation is changed in heat that penetrates through body. It is a similarity to the sun radiation when with low temperatures comes to a feeling of a heat amenity.
Exactly this piece of knowledge is used with the design of heating with infra radiators HELIOS. In contrast to the air-heating when the hottest air is collected at the ceiling, in our case the effect is exactly contradictory. A stable natural heat climate is created without noise, air draught and dust whirling in an ecologically friendly way. We lower the temperature in the hall about 3-5°C on purpose and the required heat amenity is reached by the radiant heat of the infra radiator.
It is a kind of a „completion“ on a required temperature. The lowering of the calculation air temperature of 1°C brings cca. 7% energy saving. In the present case 20 – 30%.

Watt-Flex Replaceable Immersion Heaters
Heating an acidic or caustic solution in an immersion application can be a difficult and often dangerous procedure. Dalton’s Watt-Flex replaceable immersion system eliminates the complication of changing the heater and draining the tank.
Dalton Electric’s Watt-Flex cartridge heater and immersion well system use a sheath with a welded endcap and NPT fitting that screw into the side of the tank. The sheath becomes a permanent part of the equipment. The cartridge heater is then inserted into this well and held in place with a flange. It can be removed and replaced with ease.

Silicone heaters consist of two layers of silicone with an integrated fibreglass-mesh and heating wires laid out between the two layers. They are thermally and mechanically designed to withstand temperatures up to 200°C, without losing their shape. The silicone heater is vulcanized into a homogenous unit, ensuring the flexibility necessary to adapt to the mounting surface.
